*HP EliteBook 2530p Owners Lounge*

I've sent it in, and the graphics problem is evidently hardware-based and covered by warranty.

I LOVE BUSINESS WARRANTIES. The day after I reported the issue, a shipping box arrived at my door with prepaid overnight return shipping. All responses have been prompt and direct, and I'm really enjoying how quickly they act. This only solidifies my decision to only choose among business models when shopping for notebooks.

 

Within four days after reporting the problem to HP, the computer has been fixed and returned to me. By fixed, I mean replaced by a new unit.

As a side note, the display panel in this one is a Samsung LTN121W3-L01

 

Hi guys.
I'm replacing my nc2400 motherboard with a 2530p. I just got the 2530p motherboard. its a surprisingly good fit.

Now for all the little cables... first of all, how the heck does the LCD cable connect? is it a plain old molex?
Also, is my Synaptics TM151 button board compatible? Anyone know the model of the 2530p one?

Its too bad the new bottom RAM slot isnt just a few mm lower... would have been accessible through the wifi door

I think I can figure out pointing devices. what are the palmrest cables, where would I find the PS/2 connector?

Any help appreciated. thanks.

 

Are you saying the 2530P systemboard is a direct fit into a nc2400 chassis with screwholes matching, HDD lining up in correct spot, expresscard accessible via the cardbus chassis cutout? This could be of interest to 2510P owners. Any chance of some quality pics + writeup of how to fit the 2530P systemboard to a nc2400 chassis? If it all fits then the only incompatability would be the sata 1.8" and optical drives, the latter solvable with an ebay 9.5mm ODD caddy + 2.5" sata HDD.

Also, can you ID the PLL on the 2530P systemboard. It is likely ICS9LPxxxx and will be located somewhere near the CPU with a 14.31Mhz crystal reference timing chip above it.

 

I'm saying that MOST of the screwholes match. There are some major problems near the bottom as the 2530p board seems to have a square cut out were the nc2400 does not. The very bottom right screwholes dont line up, maybe just one.

A bunch of the screws on the top edge line up perfectly, the top corners, a few in the center also. All the ports on the right side except for firewire match perfectly in accordance to the screws. The power jack on the left side lines up, but somehow the modem and usb are shifted closer to the dvd drive.
The ethernet doesnt quite line up but will with a little filing.

The 2510p is pretty different isnt it? You would probably have more luck.
Its a pretty good deal for anyone.
I just wish I'd had more money a while back... there were sl9600 motherboards for 110.

Anyway I havent looked at things in good light yet so I'l get the PLL later... also then maybe I'll start a thread with pics and exact screws that match along with chassis modifications as I get to them...
Oh and I dont think most of the components like hdd actually line up with doors on the bottom at all...

I will just have to see how this goes.

Does anyone have know of a disassembly guide for the 2530p where I would be able to see what plugs into what?

More updates later.

 

LOL this weirded me out: HP 2530P CPU BASE COVER ASSY 492547-001 Tested - eBay (item 190417942240 end time Aug-12-10 02:22:58 PDT)

...yeah whats that from like a latitude d630?? heres the actual base:


so i think the HDD is in the right place, one mini pci-e slot is completely inaccessible, the other and the ram slot will be too high to access.
maybe it will be possible to get the ram out and use half height cards... not sure yet

 

no. you need to replace the DVD tray with the HDD tray. it gives you the space and connectors for that 2.5 sata drive.

exactly. ALWAYS go for business warranty. it may be expensive, but worth every penny.

go to the 2530p support center in hp.com, then manual page, then look for "Maintenance and Service Guide". it's a 5MB pdf file.
or this link (links in hp.com keep changing somehow)

 

Hi all

I'm the owner of an hp 2530p with the sl9600 8gb ram an intel 160gb 2gen ssd
the rare thing is that what i read at this forum that the graphics preformance of the 2530p is
Graphics: 3.8
Gaming Graphics: 4.9

BUT I have
Graphics 3.9
and gaming graphics 3.4
how can the gaming preformance be higher @ an slower cpu's

 

Is there someone there??



------>Bump<--------

 

those scores are not really significant. You need 3d benchmarking tools to know whether its just a difference between your OS and the one you read about.

 

Just bought a used 2530p with the 80gb Intel SSD. The unit is running XP Pro (downgraded from Vista) and I plan to move it to Windows 7 Pro. The SSD is the first-generation X18-M which doesn't support the Trim command. So, I'd like to use Intel's HDDErase 3.3 program to restore the SSD to factory condition before clean installing Windows 7.

I've read about various problems getting HDDErase to work due to incompatibilities with certain system BIOS and disk controllers. It seems the most widely recommended approach is to run it from a DOS bootable USB drive, after setting the HD controller to "legacy" mode in BIOS. Has anybody here successfully run HDDErase on the SSD in a 2530p? Any tips or pitfalls? Thanks.

 

I'm also looking for recommendations on a good-fitting, reasonably protective but not overly bulky sleeve for the 2530p. Thanks!

 

Some bad news, I've been in contact with Abo, author of the wonderful program SetFSB. Unfortunately, he is not able to make SetFSB able to overclock the 2530p.

This is his reply:
"Hmm..., I do not have ICS9LPRS397 datasheet.
Though it is not certain, I seem Truested Mode Enable (TME) strap status is no overclocking.
Unfortunately, I cannot support it."

 

You'd get overclocking support if you do the TME-unlock PLL pinmod in my sig. Though not a good idea while under warranty.

 

Hi nando4
I have tried it and it works but after 3 sec's it fals back to the original state's


I have also an program called cpugenie where you can modify the all the (mfg) multipliers and vid's
GreenVantage LLC

 

wei scores are the same


------->Gaming preformance still low (what am i doing wrong)

 

Sounds like you have single-IDA but not dual-IDA. Can test using WPrime32. Set it to run using only 1 thread. You should see Throttlestop keep the higher multiplier. When you set a WPrime32 with 2 threads it will disable the extra multipler.

A bios hack to set MSR 0x1a00 bit 20 to be zero was required on the 2510P to get the extra multipler to run dual-IDA as explained here. 2530P uses a Insyde BIOS so the hack would be different.

If you do hack the bios, please share for the enjoyment of other 2530P owners.

 

Hi there,

This is a repeat of this post:
http://forum.notebookreview.com/hp-elitebook-probook/352887-2510p-owners-lounge-47.html#post6662803


Code
-------------------------------------------------------------------------------------------------------
I've got a EliteBook 2530P with a C2D SL9600, french located.

I think that the thermal ingenering of this subnotebook has been botched. On the keyboard I can feel 8-10°C of difference between his left and right sides. That's sucks !!!

Before having enought money for come-back to ex-BigBlue, I would like fix as possible my thermal problem.

I can't force fan on AC/DC by using bios option because I'm running Debian who can't been booted without disabling ACPI in that case (and that I won't !).

I want to enable (force) lowest fan speed for idle run for any case, I don't care about power consumption 'cause I've got two batteries ...

So I've disassembled the DSDT table like shown in nando4's linux link.
But I can't find inside the section about fan's power tweaking (there's no quote like in nando4's DSDT table post).

You can dl my DSDT table here:
2shared - download DSDT_2530p-SL9600.dst

Notice : table disassembled with iasl, please open it with vim, the windows notepad seens to alter this file.
-----------------------------------------------------------------------------------------------------------------------------

@Nando
Thanx for your anwser.
I purchase my subnotebook for new (less than 1 year), and I use it 100 hours for max, so the fan is very clean
Applying some fresh thermal compound remove waranty isn't it? And if I can't force fan on idle, new thermal compound as no real effect?
Correct me if I'm false.

To undervolt cpu under linux, I need to change my kernel and this is not the first thing I want to do (later I think, for optimisation). According to my research undervolting/underclocking have minor impact on heat & power consumption for idle run.

In my DSDT table, I can't find the section with 5 lines who contains '0x64' like explained in your 'Fan speed control by modifying the ACPI DSDT table' link on 2530p's thread.

 

Nobody ?

 

I found in Serbia renew 2530p with ssd for good price...
What are experiences with those renewed laptops, is it good to buy or not...
thans...

 

thinkaddict,

you haven't given any definite evidence that there's something wrong... like maybe the temps >_>

 

Speaking of temps, does nayone else notices higher temps when using windows 7 compared to Xp? Just upgraded and my battery life, noise and temps got worse (subjective comment, nothing measured)

 

I know I'm very late to the 2530p party (esp as the 2540p is out), but I got mine *really* cheap since its end of line / ex demo. But very happy with it so far! Much much better than my 2510p (u7600) - so much faster - gone are the 5 min boots Battery life probably isn't quite as good (sl9600) but its close.

I know this question was posted ages ago, but here's a definitive answer....

My 2530p came exactly the same. The answer is YES.
Buy part 492567-001 - ExpressCard cage assembly - $27 delivered (direct from the HP part shop Australia). It is literally the cage and eject button - the actual expresscard socket is on the motherboard already.

You then have to follow the 2530p Maintenance and Service Guide on page 88. It is not for the faint hearted. You pull apart the *whole* laptop - hard disk, DVD, screen off, keyboard off - everything. Try not to mix up / lose screws along the way. As someone else has talked about, the hardest part is getting the keyboard out - it is glued on (which the manual doesn't talk about). Just gently lift it forward, and use a flat screwdriver to directly loosen the glue. The next difficult part is removing the top cover of the laptop to gain access to the motherboard. Once you've got the motherboard itself out, the expresscard assembly is pretty easy to change for the smart card reader (which is actually an expresscard 54 card). NB - you will need a T8 hex screwdriver

Good luck.

 

Has anyone got the Samsung 128gb SSD
Model : SAMSUNG MMCRE28G8MXP-0VBH1
Firmware : VBM1AH1Q

in their system? It does NOT support TRIM :-(
I've been hassling HP's technical support - who were completely useless. I spoke to about 5 different technicians - and they varied from not knowing what TRIM is, to getting the firmware of the SSD confused with the BIOS, to
asking me to attempt to install firmware for a Intel SSD, and a non-matching Samsung SSD. Finally they fobbed me off by telling me to talk to Samsung - but they specifically say on their website that this is a HP branded SSD, and they do not release firmware directly - only from HP.

Anyone have any idea how to update the firmware? I have a feeling its not a mainstream 2530p hard disk - hence the lack of support.

BTW this thing flies! Boots into win7 64 in 30secs, resume from hibernate in 20sec, hibernates in less than 10sec! Its faster doing day to day stuff than my Lenovo w500 (T9600 / 4gb / Seagate Momentus XT)...

 

Does anyone's LCD flicker when pressing keys - only on the very lowest brightness setting? Even with the ambient light sensor off?

Has anyone else noticed the extreme power use of the un2400 WWAN card? My power consumption goes up from 8w to 14w when I turn the thing on. Also it never seems to get more than 2 bars reception....I'm using the built in win7 control to connect to Optus - and reception seems to be poorer than my 2510p WWAN....

 

First of all: Congrats! About some of the questions you've made my screen does not flickers since it was replaced. My old one used to do that but its gone. I so envy you for your top-loaded config, I wish I had the wwan card and the ssd.

About the 2540p, the one thing I love is the exaust fan now has more space since they changed to a much better port layout. Thats about it, performance wise I wish it included the ULV processors found on the alienware m11x R2.

 

Thanks fakeplasticblah...did yours flicker at any brightness level? Mine only does on the very lowest setting - and its only slilghtly (I can probably live with it). Otherwise there are no complaints.

As for the WWAN card -

$43 delivered to Australia. Very simple to plug it in. The only hassle is the non-standard screw to hold it in (not included) which is a different size to that stated in the manual. I drove around town for a half a day looking for one - and in the end cannabilised one from my 2510p.

 

Hi,

I have a question about the SD card reader: Does anybody know up to what capacity the reader supports and more importantly, whether it is capable of supporting class 10 SD cards that shuuld deliver up to 30mb/second.?

Thanks!

 

Any answers on the temperature readings? Could you guys measure yours with Windows Xp or Windows 7 (whatever you have installed) when idle? Thank you. I remember having around 50 °C in Xp without the fan always on option.

 

I have a question
i'm planing to change the intel5100 wifi cart to an intel 6200 or 6300 card because they are faster BUT are the whitelisded???

 

Annyone BUMB

 

Does anyone here has an elitebook with an ULV processor (su9300 or su9400)? How are your temperatures?
What about noise?

I really like my 2530p (keyboard, aesthetics, form factor) but I do hate the noise and the slow 1.8" hard drive so I was thinking I should probably sell
my 2530p and buy one with an ULV + 2.5" bay (cheaper ssd's)

 

Hi guys, i'm the new.
I want to change Intel Wifi Link 5100 to AR9287, but i got the "104" error message.
How can i remove/modify the whitelist or wlan card's ven_id/p_id/subsystem_id?
Thank you.

 

Try to modify the DSDT table as shown here, where code is added to reduced temperature readings by 32 degrees to limit fan noise.

Overclocking support

Latest setfsb supports the ICS9LPRS397 PLL that's in a 2530P. However, would need a tme-unlock PLL pinmod for it to work. Any pioneers willing to give it a go?

 

Hi, nando4.First, sorry for my english.
I searched the forum than i found you had modded the wlan whitelist from hp 2510p's bios.
Did you modify the 2530p's bios?
I want to change Intel 5100 to Atheros AR9287,but i got the "104" error message.
Thank you.

 

Hello folks,

I just bought a new 2530p, beautifully looking notebook-pc, but I'm having a big problem:

CPU-Whining!

Yes, I refer to the well-known high-pitch noise emanating from somewhere under the keyboard.

Is there a working fix for the 2530p? It's driving me nuts :{

 

No, thank you. Most 2530p's are still under warranty because of the marvelous 3 year on site warrranty they have.

I believe the whining is the nature of the C-states of the processor. (Not sure about that)

 

As already proud owner of a 2530p, I followed nando4's advice and have me

2530p with 4GB ram, dvd, blah-blah
+ original caddy
+ 750 WD drive in the caddy
+ external box for the DVD (working beautifully)

Now, I have two more questions:

1) Where can I buy a GSM module to use mobile data? How is the module called?

2) Can I downclock the system to reduce CPU load and temperatures to reduce the vent whine?

Thanks!!!

 

I heard so, too. The question is what I can do about it. Other HP-Books have been provided a fix, for example via a BIOS-update.

 

Apply http://forum.notebookreview.com/del...dvanced-rmclock-powersaving-whining-stop.html . The undervolting may also quieten down the system fan due to lower running temps. It's also possible to use Throttlestop to do Undervolting and disable c-states.

 

Ebay is your friend. For example:
HP un2400 EVDO UMTS HSDPA 3g Card 4 8530W 2530P 6930P - eBay Other, Wireless Networking, Networking Communications, Computers Networking. (end time 04-Nov-10 23:13:08 AEDST)

About $40US. Its called the un2400. If possible get them to include the screw to hold the card in place - cause its non standard and hard to find.

Good luck

 

Adding the aspi-table (load.bat says it suceeds) provided bei nando results in a blue screen @ Win7 Startup. Anyone else experiencing this problem?


edit: I was able to compile my dsdt with the iasl (intel), asl (MS) just gave me errors. Unfortunately I can't find the entry for fan-control. Means there's just no list like 0x64 ... 0x00 which indicates the fan control in other hp-notebooks.

 

TTAV134@mydigitallife has done it again. 2530P owner's no longer having to endure with HP's self-serving WWAN/wifi whitelist. See modified bios in Wlan/wwan whitelist removal .

 

thank you for your information, nando4.

 

Thanks it works now I have an ubiquiti sr71e in my 2530p
The only thing that not workd is automatich wifi lan switching and the wlan button does not work



I'm trying to tweak my memory with memset 4.1 but everythng i try, memset will not change anny setting since I changed the mainboard to an sl9600 <--------- annyone

 

Just purchased a 2530p here. The 2540p was just a bit TOO much for the config I wanted...and got 4gb, DVDRW, and 128 gb SSD for about $600. In addition, researched and found out I could run XP as a downgrade for either machine. Given I have about $2000 in software Windows 7 won't run and I can't afford to replace, this is the way to go...

Problem is this...learned that the system coming is very unlikely to have the XP image on it...as that was cut off in December...so looking for the XP disk image..i.e., an XP recovery disk to get this thing set up. Can anyone here help? I've seen a few sites that offer to sell a recovery disk, but somehow suspect it'll be missing a few critical things...like the proper installation of the SSD. I'd be happy to pay a modest cost for anyone who can help out. I'm at [email protected]. Thanks!

^1 Requires a Stage1 modded dual-IDA bios + Throttlestop to overclock using an extra multiplier.
^2 Requires a Stage2 PLL TME-unlock as noted below.
^3 Requires Stage3+4 modifications as noted below.

Stage1: overclocking with an extra divider

I was able to dual-IDA overclock a [email protected] after this stage. Flash the 2530P dual-IDA bios and follow instructions to gain an extra CPU multiplier via Throttlestop, netting you 12-17% more cpu performance.

Stage2: TME-unlock the 2530P's ICS9LPRS397DKLF PLL for software overclocking

I was able to do a dual-IDA+setPLL overclock to 316Mhz (2.5Ghz on a L9400) after applying this stage.

The free setPLL and the US$10 setfsb support the 2530P's ICS 9LPRS397DKLF PLL making it possible to overclock the CPU up to the final point of stability that's within thermal limits. Before spending the $10 on setFSB I'll advise that it causes a intermittent hanging which appears to be related to the optical drive sata controller. No such problem with setPLL however.

A TME-unlock (Trusted Mode Enable) PLL pinmod will be necessary to allow software overclocking to be possible. Ref similar 9LPRS387 datasheet. Example setPLL commandline I use to do my AC overclock and DC downclock are below. These are included in setPLL's automated\ directory as AC-overclock.bat and DC-normal.bat

1. Access the PLL by removing the RAM slot cover and RAM module from the underside of the system.

2. The TME_unlock mod. Connect an enameled (clear shielded) copper wire to the PLL pin 14 (PCI2/TME). Attach the other end of the enameled wire to a 100ohm or less resistor. Wind a single coil of the resistor's leg around the nearby screw and cut off excess. This is a pull down resistor setting the PCI2/TME pin to Vss (logic 0) which disables TME.

3. Place some insulator over the resistor so a short circuit could never occur.

4. Check the TME_readback flag in setfsb to confirm TME is now unlocked. Can use the freeware version with the ICS9LPRS365 PLL to check.

5. Pic of the 2530P cooling system. Can slightly improve cooling by replacing the factory thermal compound.

This very simple mod only solders to one point on the systemboard AND can easily be reversed. A mobile phone technician could do this for you for less than $10 and take less than 5mins to do.

Stage3: flash the PC2-5300 RAM specs to one RAM module

I was able to do a dual-IDA+setPLL overclock to 326Mhz (2.6Ghz on a L9400) after applying this stage.



Left: PC2-6400 (800Mhz) RAM, Right: PC2-5300 (667Mhz) RAM

Trying 2.6Ghz would intermittently freeze on overclock with video artifacts due to the 4500MHD IGP. The workaround was to flash one RAM module as PC2-5300 spec (667Mhz) using SPDTool, which was very easy for me since one of my modules came from a 2510P. I just reversed the PC2-5300 to PC6400 process. Using PC2-6400 RAM means the 4500MHD boots up with 533/333Mhz timings. When one PC2-5300 RAM module is detected the chipset runs at the lowest compatible RAM timings, 333Mhz in this case, with the IGP set to boots up with 320/300Mhz timings.

Stage4: Decrease 4500MHD Core render clock and timings

I was able to do a dual-IDA+setPLL overclock to 330Mhz (2.64Ghz on a L9400) after applying this stage. Without this stage I'd otherwise see intermittent 4500MHD freeze on overclock.

i) Decrease 4500MHD Core Render clock from 400Mhz to 266Mhz

I use setPLL's setIGP command to do this: 'setIGP 266'

ii) Set the 4500MHD power settings in the systemtray maximum savings

This is an extra small measure to slow down RAM timings further to prevent video artifacting. This also means that if doing a resume-from-standby/hibernate overclock, ensure your script does a 'taskkill igfxpers.exe' then 'start /b igfxpers.exe'. Add some delay time before setting your PLL to ensure igfxpers has time to reinstate this setting.

iii) Set the multimedia settings to optimize power savings as shown in spoiler to ensure your youtube videos play without random exits

Spoiler

OPTIONAL: slow down RAM timings

This was not necessary on my system, however if you are overclocking further or have poorer quality RAM then this may be necessary.

i) Change 333Mhz SPDTable entry to CAS=6 timings

Use SPDTool to do this. This will give more RAM stability on higher overclocks. This makes sense since at a 266->333Mhz BCLK overclock will see the RAM running at 416Mhz when the system boots up using PC2-5300 RAM timings. Do this using SPDTool, effectively making the 333Mhz SPDTable entry the same as the 400Mhz entry in PC2-6400 RAM module. Could take this step further and change the whole 333Mhz SPDTable entry to 6-6-6-18 timings.

Optional: use the platform clock

If you do not use that and increase the BCLK, you system will perform better in benchmarks but games may give incorrect benchmark results due to the timer being slightly off. With this change, it will use the trueplatform clock reflecting correct benchmark results and give better playback of games.

At the command prompt type:

Code:

bcdedit /set useplatformclock true

To revert the change anytime enter this at the command prompt:

Code:

bcdedit /deletevalue useplatformclock

Find stable AC-overclock and DC-undervolted voltage limits

Within Throttlestop I set my CPU to 1.225V (highest) then set it to do a dual-IDA overclock (right click, start dual-IDA). Then I used setPLL to overclock until the system froze. I rebooted then backed off the BCLK used and tested with Everest's Stability test until it was stable. Then I went back into Throttlestop and lowered voltage until the system BSODed. Rebooted and then increased the voltage by two 0.125V levels. The result will be the lowest voltage that can run the highest BCLK at the highest multiplier to keeps temps at their lowest. Then I tested what was the highest multiplier I could run at the stock 266Mhz BCLK at the lowest voltage (0.925V).

The final result of testing showing I can run [email protected] (AC, 2.64Ghz) and [email protected] (DC, 1.86Ghz). The undervolted DC setting giving better battery life than the factory-delivered state.

Overclocked CPU temperatures observed

If overclocking then consider observing CPU temps to ensure operation stays as far as possible below Tjmax of 100C using tools like Everest or Throttlestop. Can also increase fan rotation to remove heat faster.

With a 22 degree ambient temperature AND with the rear right cover lifted to allow airflow, I did an Everest Stability test. Running the 2.64Ghz [email protected] at 100% load saw a maximum temperature of 73 degrees. Running 3dmark06 in the background saw temps climb to 76 degrees. The right side of the system where the fan is was warm to the touch. We see the system is well below Tjmax. Though I wouldn't advise running it at 100% cpu+gpu load for extended periods of time unless improve the cooling system, invest in a notebook cooler or run with the faster fan speed and elevated rear right corner.

Better removal of CPU/gpu heat can be achieved by application of some decent Artic Silver thermal paste between the CPU/northbridge and the heatsink as well as clearning/blowing out any dust or gunk accumulation blocking the little fan under the system.

Overclocking wall due to chipset and/or 4500MHD graphics

Overclocking my L9400-1.86 beyond 340Mhz sees a BSODs, regardless if I pull back RAM timing or give the CPU more voltage. Looks like then it's either a chipset or CPU internal cache wall.

A L9600 can be overclocked to 323Mhz with an extra multiplier bringing it up to 2.9Ghz. Careful with voltage and associated temperatures if you wish to test. My L9400 can go up to 1.225V but I wouldn't advise going that high - the 2530P cooling system would be insufficient to remove the heat under full load.

overclocking side-effects

The system will not restart properly with the AC overclock. it will either just shutdown or attempt to do a reboot and hang. Workaround is to just do a shutdown and poweron instead. Standby/resume works fine.

setfsb hangs on startup with some problem related to the DVD. No such problem if using setPLL.

Conclusion

Running my 2530P with an overclocked+overvolted [email protected] (AC) and undervolted [email protected] (DC) provides additional performance when plugged yet sees lowered power consumption on battery than prior to tweaking.

Appendix

Appendix 1: Overclocking in Linux

Pre-requisite: a TME-unlock PLL pinmod as described above. Dual-IDA can be enabled on Linux as described. The PLL can then be overclocked in Linux with the steps below.

1. Download lfsb-ics9lprs397.tgz. Extract and copy the precompiled lfsb-x86 (32-bit) or lfsb-x64 (64-bit) into the path /usr/local/bin directory OR extract over the lfsb-0.4.1 package and recompile.

2. Enable the SMBUS controller. Add entry below to your Linux bootitem in /boot/grub/grub.cfg:

Spoiler

Code:

# Enable the SMBUS controller at RCBA+0x3418h (FD register). 
# On a 2530P this is at 0xFED1F418

write_dword 0xFED1F418 0x3380001

3. Test overclocking with one of the following frequencies: 266-357. I use 333 (ie: 1.86Ghz -> 2.28Ghz), checking the faster glxgears response with the faster FSB. NOTE: lfsb reporting of CPU frequency is not accurate - overclocking IS active..

Spoiler

Code:

# glxgears
5155 frames in 5.0 seconds = 1030.906 FPS
5149 frames in 5.0 seconds = 1029.697 FPS
5295 frames in 5.0 seconds = 1058.589 FPS
^C
# modprobe i2c_dev
# modprobe i2c_i801
# lfsb -y ics9lprs397 333
-------------------------------------------------------------
CPU frequency : 1602.73 MHz (estimated)
PLL ics9lprs397 is supported.
FSB=333 MHz
-------------------------------------------------------------
Changing to:
FSB=333 MHz
FSB frequency changed.
-------------------------------------------------------------
CPU frequency : 2280.17 MHz (estimated)
FSB=333 MHz
-------------------------------------------------------------
# glxgears
6408 frames in 5.0 seconds = 1281.436 FPS \
6525 frames in 5.0 seconds = 1304.862 FPS [COLOR="Red"]-- Improved rendering speed[/COLOR]
6444 frames in 5.0 seconds = 1288.656 FPS /

4. If overclocking is stable, add to be automatically started up:

Spoiler

/etc/modules

Code:

# wifi - before the i2c drivers 
iwlagn

# Add i2c modules to be able to communicate with the PLL for overclocking
i2c_dev
i2c_i801

/etc/gdm/PostLogin/Default

Code:

# Overclock 2530P from 266->333 FSB
/usr/local/bin/lfsb -y ics9lprs397 333

5. Add overclock upon resume-from-standby or resume-from-hibernate by creating script as shown below:

Spoiler

/etc/pm/sleep.d/02overclock

Code:

#!/bin/bash
case $1 in
   hibernate)
       ;;
   suspend)
       ;;
   resume|thaw)
       # need to re-init the i2c bus after a resume
       modprobe -r i2c-dev; modprobe i2c-dev
       modprobe -r i2c-i801; modprobe i2c-i801
       
       # Overclock after standby
       /usr/local/bin/lfsb -y ics9lprs397 333
       ;;
   *)
       ;;
esac

Appendix 2: U9xxx owners: consider a FSLx pinmod to run 6x266Mhz 1.6Ghz, or up to 1.95Ghz with setPLL

The PLL FSLb pin2 (2nd one down from the top left corner) has a resistor connected off it and is set to be a logic 1, meaning 200Mhz BCLK. Attaching a wire+resistor as shown in the above TME-unlock, or simply daisy chaining a wire from a tme-unlocked pin14 to pin2 will change that pin logic to 0, setting a 266Mhz BCLK (see details). The chipset will detect this and lock the cpu to 0.9V and a x6 multipler. So a U9300/U9400 would be running at 266x6=1.6Ghz. If the PLL is tme-unlocked then can overclock further from 1.6Ghz using setPLL up to the point of instability.

Though consider if you *dont* do a FSLx pinmod then you may be able to dual-IDA+setPLL/setfsb overclock to a higher point with the luxury of higher voltages available. Only problem might be 4500MHD graphics might start glitching. Certainly a U9400 would already run at 1.6Ghz dual-IDA, so I believe could just be tme-unlocked and setfsb overclocked to 2.0Ghz.

m11xR1 owners have got their SU7300-1.3 CPUs up to 2GHz with exactly the same modification. I found the chipset limit of 333Ghz on my system, so running a U9300/U9400 at 6x333 would be 1.95Ghz.

undervolt INFO: 0.925V DC undervolt with measured power consumption

My DC profile is as follows:

1. Run [email protected] undervolted as discussed in the previous section using Throttlestop. Use "DCExitTime=5" and "ExitTime=5" in throttlestop.ini so TS exits once it's set this up to reduce monitoring load.

2. brightness set to 3 bars

3. wifi 'power transmit' set to 5. Highest. Ad-Hoc power management set to "maximum savings"

4. Set 4500MHD graphics to "maximum power savings". Ensure have a single display setup. Using the "clone display" adds 1.5-2W extra overhead.

5. BIOS has LAN disabled

6. Mute the audio device

7. Disable system paging file to reduce SSD/HDD access.

8. Install the Intel RST driver then AHCI Link Power Management - Enable HIPM and DIPM - Windows 7 Forums . This will reveal AHCI Link Power Management in Power-> [Plan]->Advanced->Harddisks. I set these options to HIPM+HIDM and 100ms respectively as shown below:



9. Install the Firefox flashblock plugin to prevent flash pages from kicking up CPU and iGPU utilization in the background.

So with this DC profile my system idles at 4.6-5.0W (!!) wifi on three bars at idle. This is very impressive. My 52Whr 6-cell is lasting 7:43hrs as confirmed by batterybar. If I had a 93Whr 9-cell battery then I'd be getting 13:50 of real battery life.

Hi Nando,
Long time ago


i have an 2530p with an sl9600 (2.13ghz)
the dual ida bios work
but is there an option to have ida inplemented in the os??
i have tried to pinmod the pll (r=22ohm)but after setpll to 300 the system freezes after 5 sec and dit not reboot
I taked out the battery and power adapter wait 5 minutes reinstalled battery
WHOOOW no boot (black screen fan running)
cut the pinmod wire from the resistor and then it booted


is placing the resistor to ground the ony thing to do did i forgot someting



for undervolting I use CPUgenie but the 9x multi is not there???



PS.
VERRY NICE WORK

 

I have a 2530p mainboard which running B.0B bios, I installed linux on it.
Does the setfsb module in grub2 works for your 2530p?
Any dual-ida solution in linux?
How to flash the B.0B bios to F.13(modified) one, I heard that it require a B.00 one to switch from B to F?

thx.

 

I've added Appendix 1: Overclocking in Linux here in response to your query. The additional ics9lprs397 PLL file added to lfsb could also be added to grub2-setfsb if you prefer to overclock at the bootloader.

I've also just posted DIY ViDock Experience: HP 2530P + NVidia GTX460 @x1.Opt. The recipe making it easy for other 2530P owners to duplicate if they want accelerated/gaming graphics, HDMI audio/video or multi-monitor support.
