PLL Pinmod Overclocking Methods and Examples

Actually when I opened it, I took a peak in the upper part of processor there was T9300 an SLAVY was printed, I remember... but what matter [from what I know] is revision, and mine is C0 like in the description by CPU-Z
you know what is odd ? when I use orthos there is no problem on stability test, but when I give torture with prime95 or OCCT... pfuu, it's auto underclocks which still keep my laptop from shuting down... when just notepad/browse net simple, the idle is like 45 degrees Celsius.
I have problems with the RAM too...

-if Samsung 800Mhz CL6 standard is inserted, after "Windows is loading" the BSOD makes it appearance.
-if Samsung 800Mhz CL6 is moded to JUST CL6 using SPDtool, again the same problem
-if Samsung 800Mhz CL6 is moded to 667 CL5 using Thaiphoon Burner and then mod to ONLY CL6 using SPDTool, Windows is on but some stability problems make their appearance [memtest too, won't pass, error detected]
1066 ddr2 is not available and the cooling system is, as I say, powerfull
if I could increase the ram voltage from 1.8 to 1.9, that should fix the problems [and maybe even run 800 at 1066]

 

About your memory try flashing your 1GB to 667MHz CL5 (all timings default).
My system wouldn't run for more than 533 because of my IGP(x3100). You can try flashing your RAM @533 default timings and check the result.
FIY if you have a module running @ 533 or 667mhz the otherone will use the same tables (even if it is a 800MHz module) so if you find a working setting then you can add your 4GB module and it will adjust at your current setting. Then check with memtest your 4GB too. Right now I'm using DDR3 modules so I won't be of much help.

 

flashing the ram any way it doesn't get stable, I tried every single way, just the original flash with downclock, by modifing manually the timings... no way
now I'm running my unflashable 4gb 800mhz ram at 1066, however is not stable... I just browse the net, everything simple
-when using moded ram; 533 won't start at all, 677 start 1/5 tries
-when using original ram; 800 start 5/5 but not stable... if I can voltmod the ram to 1.9, that will do the trick, or buy 1066 ddr2 [very hard to find here]

I saw something weird on the ram, the flashable one has just 1 brown (resistor?) on the corresponding spd chip, and the unflashable one has 2, 1 black and 1 brown: I check all available ram, I have 3 sticks, my girlfriend has 2, and 2 to another laptop, all the same thing [I think that's the trick to make it flashable]...
however I need volt increase on the ram [bios doesn't provide anything-fujitsu is hard to crack], any ideas ?
as I can figure out there are only 2 things to make it work: increase ram voltage or replace with 1066 pc2
now I use setpll/setfsb to downclock to get stable until I figure out a solution

 

Intel Chipset 4 (i.e. GL40, GS45...) don't support RAM or CPU at FSB 533MHz.

I wrote this thread a while ago. I tested 17 modules of RAM. I found that A-Data RAM (amongst those I had at the time) was the best, since it overclock and it can be flashed. Some of you guys have been flashing Samsung RAM. I had mixed results with Samsung RAM. When I wrote the above thread I couldn't flash any of my 4 Samsung modules. Recently I tried another Samsung module and I was able to flash it to 533 and back to 667MHz.

According to your experience what are the other brands that can be re-programmed?

 

I saw your thread and is great, however there is another way of checking if it's unflashable: using Thaiphoon Burner [ EEPROM>PSW Protection ], and if there is all grey [unable to modify], then you're stuck, else there can be click-check [but DON'T do anything there or you'll block the ram by yourself]
for now I saw the ram builds from the same manufacturer [pcb+memory] is flashable: Samsung PCB+Samsung Memory is flashable, Samsung PCB+SEC Memory is unflashable [and has, as I said in a previous, two resistors on the back of SPD chip] [SEC=samsung semiconductor, maybe their partnering is not such good for us]-now I'm far away home and I'll come back in a few day, then I'll make some pics about SPD and maybe we can make them all flashable by hard moding -for now I'm interested in voltage increase
I check also the PM45 and saw the 533 is unavailable but I saw many computer anomalies so I'm used to "that shouldn't work, but it does!"
FACTS: I'm running 800Mhz Samsung CL6 [unflashable] at 932Mhz and it's ok, but my target is 266Mhz FSB => 1066Mhz PC2 ram [flashing any way doesn't help to 677 CL6, still big problems, so raising the voltage should solve, if not then voltage+flashing should definitely work] - I'm also interested in buying 1066 PC2 for my notebook but I have a hard time finding [in Romania I doubt I'll find it, however I'm available of buying abroad]
maybe someone knows if SPDtool works to change voltage ? or any other idea ?
form factor 200pin, memory standard DDR2-1066, look like it fits due to the pin, what do you say ? the PM45 support the speed, but the slot ram is pc2 so the pin position needs to be look for my desired ram

 

I tried that and the laptop didn´t boot. But It didn´t boot also when I tried to BSEL pin mod the CPU to 200 MHz, which I don´t quite understand why happened, because I was expecting a boot with a locked multiplier (in fact, the error message is the same: power led going from green, then red, then orange, and then stays at green --> No boot). Does that means that this chipset won´t accept a mod at all? Do you think there is a way I could try to BSEL again in a successful way?

 

Does anyone know how get Thaiphoon Burner work on a Win 7 64bit system?
I tried to disactivate the drivers signature and I still can't get it to work!

Thanks for the clarification.

I know for sure that 533 doesn't work with the GL40. I flashed a samsung ram to PC4200 and tried it in two laptops and it doesn't work. I also tried a T2370 (CPU with 533FSB) and it didn't work.

 

enter in menu by pressing F8 after BIOS [but before Windows starts] and select Disable Driver Signature Enforcement, I tested on the laptop I'm moding with Win7 SP1 x64 Ultimate and is working like it should, however you may want to disable permanently drivers checking or maybe a tool to do that

 

g
I try the above by didn't work for me with the 14 days trail version. Maybe I'm doing something wrong. I'll try again later and post back.

 

send me a pm and I'll help with that

@Andreche there is a chance to work when you remove the pin and "leave it free" BUT it will work for sure if you ground it via a 10k resistor, my temp server will give you an idea [I will update the picture 'cuz I've modified the mod ] -look at the yellow moding, you cut then solder the resistor between the "just freed" pin and a GND point [you may use any screw hole as a ground or make it look good by checking a condensator as your GND -I also used a 10k small resistor from a mobile phone 'cuz I wanted to be elegant , and for the wire you can cut an IDE cable, the ones you use for old cd-rom and hdd; that's small too and is protected as well not to make smoke

 

I'll PM you shortly.

In the mean time this is what I get when I use and when I disable the drivers digital signature (with F8 or though the command prompt).

 

To make the app run on 64bit, Disable Driver Signature Enforcement using F8 after BIOS AND run as Administrator... however to write/flash, you need to register the app
regarding RAM voltmod... anyone knows how to do it, some ideas ? there are no bad ideas, they're only different... so hell ya I'm listening !

 

That´s what I said I did in my previous message, although my case is a special one, because the FS_A pin on the PLL is also an 48 MHz output, so I can´t separate it completely from the board (I tried though, via a 10 K resistor to ground and it didn´t work). But, actually, I don´t know if that´s the problem, because the system should boot with the BSEL pinmod @ 200 Mhz with the locked multiplier, but it doesn´t, so I´m trying to figure out why this is happening: more voltage?, higher RAM speed?, etc...

My guess is that if I´m able to BSEL pinmod @ 200 MHz successfully (with locked multiplier at lowest), then I can try again the FSLx pinmod, hoping it will work.

Anyway, thanks for your help bro

 

@Andreche
Doing FSLx mod, you have to go GND because of the 48mhz, but still the laptop won't start; Don't do BSEL ! do voltmod !
my T9300 works ok with stock voltage up to 250fsb [with error], doing FLSx 266 didn't start so I increase with 0.1, still didn't so VID_4 +0.2 did it ! [increase with 0.2, check intel datasheet to know what VID is for you]

[sorry for my english if there're some mistakes but this is not my 1st language-I'm romanian]
ON NOTEBOOK, until now, I found out that the ram with PSW Protection have +1 black resistor on the back of SPD BUT this isn't the protection !

the BIG question:
if I rip the unblocked SPD EEPROM chip from a dimm and replace the one blocked, will that do the trick ? YES IT WILL ! I actually tested that, and that's what I'm running !
I've done TME-unlock and FSLx PLL mod on Fujitsu Amilo Pi 3560, the T9300 is ok at 3.6Ghz with VID_4, my Patriot 8GB DDR2 [2x4GB] at 887Mhz [125$ brand new, Romania] and my GT 240M 1GB GDDR3/128bit at 675/1485/932 is boosting this baby to the cloud ... after so many hours of theory, sketches and work, NOW I can finally say I can go drink a few beers [with the money left after the quite big investment]
I will make a full review about all modification and the entire device, a video too AND... my advice is [after I've brick 2x1gb eeprom]: buy the oldest and the cheapest desktop ram you can find [and unlocked/flashable too]! you just need the SPD chip to be unlocked, then you rip it and solder it to the ram you need to flash. start the laptop with a ram that just works, HOTFLASH the ram moded in, and using Thaiphoon Burner/SPD Tool flash the freq/timings you need...SO:

Q: How can I check if my ram is flashable/unlocked?
A: You can check if there's a black resistor on the back of the SPD chip; if there is, then you're locked.
A: You can check by using Thaiphoon Burner by EEPROM > PSW Protection; if there're all grey, you're locked [if you're 64bit, press F8 and select Disable Driver Signature Enforcement, and run as Administrator or disable UAC].
A: You can check by flashing anything with SPD Tools BUT don't restart after that so flash again what you need; if there will acknowledge you about any errors, you're locked.

Q: What's with the black resistor thing on the back of the SPD chip, does it need to be removed?
A: I actually think it's kind of protective and has to do something with the pin7, but what I know for sure is that this black resistor is just on the back of the official blocked ram! this has nothing to do with the PSW Protection so leave it alone !

Q: So ya, I checked the ram, it's blocked ! what now ?!
A: Actually is easier than we all thought... just use ANY flashable/unlocked EEPROM [SPD chip] to replace the one from the ram you're working with. You mai flash the EEPROM to fit the ram BEFORE you do the mod, OR HOTFLASH the ram and flash it after.

Q: I've done it and it's working great ! iupiii , BUT what about the ram from which I 'stole' the SPD ?
A: if you'll interchange the SPD beetween the dimms, the 'stolen' ram will be locked and will work ONLY IF the dimms have the same space and less or equal frequency

Q: What if I'll leave the 'stolen' dimm without SPD, will it work ?
A: I'll try this tonight and post later... [I think it will work if you use together with another dimm with SPD, or the BIOS has been set to override the ram timings]

The best timings explaination I found is at tweakers, do you know somewhere better ?
+after VID_4, some strange things I [theoretically] think happen: [am I correct?]

 

Great help! +rep for awesome
This is a great way to save money. You can start a thread : How to flash ''locked mem modules". It will be very helpfull.

 

Hi there bro (and bros), I was about to test the method above (starting with +0.1 voltage increase), but before I did it I decided to take care of the annoying password that my laptop keep on asking me at boot up everytime I saved new options in BIOS (for some reason the password I set years ago was reset to an unknown one, so all I could do was make use of the fingerprint recognition to get in. Lucky me). Looking around I found out that I could clear the CMOS (just like I did with my previous desktops... easy and safe stuff) by shorting the appropriate pads in the motherboard. I have all the documentation needed for my laptop, so it was not difficult to find the pads and to short them for some seconds. Then, turned on the laptop, NO BOOT.

Since that horrible moment I´ve been trying to figure out what happened and testing all kind of stuff to make my system alive again (Charged RTC battery for a whole night=no boot, unplugged RTC battery=no boot, Phoenix Bios Crysis Recovery method= doesn´t read the USB floppy.....). It´s very weird because all I did was a simple short for some seconds in the pads labeled "clr_cmos", so I don´t know what was triggered by this. The only thing that comes to my mind is that the RTC battery became dead after this... but It doesn´t make so much sense.

Well, any ideas are very welcome brothers, sorry to bother you with this post, but I thought that it was not unappropriated to say it here, since I´ve been working in the pinmod for the past two months, and maybe I did something wrong...?

Thanks in advance, and I´m sorry to disturb you guys.

 

@Andreche, listen... and listen good
my bad: after moding my Fujitsu in any way, my display died [I won't replace the display, so I transformed this into a nice, powerfull little desktop ) by connecting to a 20inch display]
my advice for you: do NOT do anything with your bios, it's ok... what you need to do is:
-reverse any moding you've done [that sucks!] VID_x, bsel, remove any mod !
-to clear the bios, remove the battery and ac power cable and then remove the BIOS battery for like 10-15min [that's more that enough]
-make sure everything is ok with your ram, cpu
-after 10-15min, reconnect the BIOS battery, the battery and AC, then start your laptop -look very close to your display, does it turn black [or maybe the lids iluminates ?]

I tried every single way to flash the ram using the tutorials found, it won't work because they're not updated ?
tested and working to boot from usb -NOW you'll know what there's working because the bios beeps come to the rescue:
FOR Phoenix:
-format USB stick using HP Tool to fat32 and make it bootable by using win98 files
-then copy your bios file [ BIOS.WPH], your PHLASH16.exe and AUTOEXEC.BAT with the content as command PHLASH16.exe /s /X BIOS.WPH
-shutdown, remove the hdd because you're display-blind and you want to automatically boot from that usb
-plug your usb and start your computer, the usb stick start working and the appropiate bios beeps are given [checked that on internet to see what's wrong -mine where long, short, short, short -meaning no video adapter pluged in -internal connector or display died]

 

anybody can help me on how to overclock my laptop to 2.79GHz????
this is my PLL pic


the clock gen is SLG8SP556V
my system spec is in my signature

EDIT:
last time, ive cutted pin 2 to set my BCLK to 266 but when i turn on my laptop it wont boot.....
theres a connection from pin 2 to 1 point that there are no resistor on the connection
i think my pin 2 is not connected to anywhere because the connection just ends near the pin 2

 

before asking something, read what is already written. I've also personally written why it may not boot... hint: cpu voltage [I recommend to do what I did: read ALL >100pages of this topic, many problems have been found and resolved]

 

Hello,i go to overclock my laptop,but i don,t know my pll of my motherboard(Quanta 3628).My procesor is T6600 2.2Ghz.
Sorry for my vocabulary i am spanish.Thanks

 

Hi,
sorry if the following thought came up already. In the Vostro 1500 bios i disable EIST so Throttlestop can do a little overclocking(T8300 to 2600MHz).

Pinmodding CPUs with Intel chipset leads to only getting the smallest multiplier = turning off EIST. Isn't this the exact scenario ThrottleStop needs to be working?

 

About setPLL, I have downloaded and played a bit around with it. First, thank you for bringing a tool like this to life. Althrough, I were not able to see Acer 5739G in the list. Is there any possibility to add or together do this? I have untill now used SetFSB, but it has not been stable. Sometimes it workes sometimes it does not. Any help will be appreciated.

 

Hello all,

will this PLL mod work with ATI chipset+ AMD CPU? for eg. on Dell 1501 ?
Thanks

 

I'm about to OC my Lenovo X61 Tablet (L7500 1,6GHz) and would like to clear a few things up before frying the hardware.

1) The PLL: SLG8LP564 datasheet, Pinout ,application circuits Low Power Clock Synthesizer For Intel Mobile PCI Express Chipset . Is it correct to asume the "method 3" from the thread opener? Eg. I should connect a 2,2kOhm resistor from GND to pin 7 of the PLL to achieve the OC?

2) Are the PLL control registers read only during boot, or does changing FS_B during run-time also change the system FSB during run-time? This is important as I'm planning on linking the state of the overclocking to the position of the tablet pen (there's a sensor/switch inside) during boot. Pen inside during boot -> 266MHz FSB, pen outside during boot -> 200MHz FSB.

I've already bought PC6400 memory, which should cope with the increased speed.

Apologies for the possibly noobish questions, but I've seriously tried to dig into this issue. Even attempted to read some chinese Lenovo forums via google translate

e: Images from chinese site suggesting cutting the pin7 wire. Quite confusing.

Three things:

1. The 200->266Mhz FSLx pinmod involves setting FSB_B to logic (0). The forum indicates disconnecting pin7 from the circuit is sufficient to do that. It would be if the PLL then internally defaults to logic 0.

2. the PC6400 RAM will still boot using the 333Mhz timings when you do your 200->266 PLL overclock. Some RAM has tolerance to accomodate the higher, most don't. In which case refer to the first page on how to slow down timings by increasing *at least* CAS.

3. I *believe* the PLL samples the FSLx pins on bootup and then maintains those settings based on reading some datasheets. So your pen idea might very well work. I say believe because I've never tried it to confirm.

You do know too there is a dual-IDA bios for your system that would get you a 1.8Ghz overclock already? See http://forum.notebookreview.com/len...s-cap-willing-pay-solution-8.html#post6501443 .

 

there ya go, these are my results, no info pops, only my clocks. but like i said the 3 consecutive ones after work too, but none actually overclock anything, it stays still in cpu-id

 

Can you download RWeverything and click on the clock generator and see if you get any info there?

 

yeh im in the process of downloading v1.4. anything specific you need to see, so i can snip, and show you?

 

Just the clock generators registers/bytes.

 

so this is what pops up when i click on the clock generator.


and my clock gen is empty with this

 

If you open setfsb, select "pll diagnosis" as the clock generator, click on the diagnosis tab and click getfsb, do you get any bytes/registers that show info?

 

no its empty as well. im kinda stumped. but ima novice at this stuff, still learning. idk what it can be, or why its not accessing the info????

 

I'm also stumped, I wonder if your smbus is enabled.

You can check using bar edit, as shown here:
http://forum.notebookreview.com/har...rclocking-methods-examples-8.html#post5291533

Or you can trying using grub2 to enable the smbus (harder to do in my opinion):
http://forum.notebookreview.com/har...es/429883-overclocking-cpu-2.html#post5463071

 

i was just thinking if my smbus, was enable too. but idk, so with enabled, there might be a chance that my pll is not locked after all, hopefully

 

can you send me a link to that? so i can check my smbus?

 

http://www.tweakers.fr/download/BAR-Edit.exe

 

I have it up and running, tbh im kinda lost on what im suppose to do next. i think i found the RCBA? can ya instruct exactly what im tryin to find

 

You find RCBA, add 3418h to it and then type that number in the memory address box of bar edit.

Then you will see the bit you need to change from 0 to 1. Unless it's already 1, then you have a different problem.

I would take apart the notebook and find the PLL, look for a datasheet online and then do an fslx pin mod to overclock if possible.

 

well it was at 0. and i tried to put 1 to change it, but it change my whole number list, rather than just that single number.

 

this is what im getting in speedfan

 

I don't know what the problem is, you could email the creator of setfsb and ask him why you don't see any pll registers when you select PLL diagnosis. But he will probably ask for a donation.

You could also contact the person behind RWeverything and get support from them, that should be free.

You need one of those 2 programs to work if you want to have a chance of overclocking from windows.

Another option would be to try GRUB2 overclocking or with a PLL pin mod.

 

hmmm, well. where can i message to support for RWeverything? and do you think my smbus driver is installed, i just recently upgraded to win7ultimate, and there is a few things that dont have a drive, like broadcam USH, and base systems. any clue?

 

oh and one more question hazard. i was looking into buying an external Gpu for my laptop, via expresscard slot, buying a egpu kit. would i have problems installing with my m6400 q43 core 2 duo. win7 ultimate. i wanna get this here ImageShack® - Online Photo and Video Hosting

 

There is an email address if you open RWeverything and go to help > about.
I have no clue about your smbus, sorry

I haven't been keeping up with either of the eGPU threads on NBR, so I can't help you with that.

 

Managed to TME-unlock an ICS9L VRS387.
Only difference with this PLL compared to the ICS9L PRS387 that I have found so far is that the PLL1 M/N enble bit is bit 2 of byte 21 (instead of bit 0 of byte 21).

I was able to underclock to 120mhz (from 166), but I can't go above 169mhz.

It can't be the ram or CPU that is making it unstable past 169mhz, but I dont know what it is.

Still working on this one, once I'm done I'll take a photo and add it to the table.

 

I'm sorry, this is really random, but did anyone else try to click the OK button?

 

Here is my situation and nothing happens.

5920G

I mean - boots normally, hangs when I try to overclock it.

 

Is that a TME mod?

Your CPU and sata clocks might be on the same PLL, that would make it hang when overclocking with software.

I have this problem with my netbook. I've tried loading an OS on a usb HDD and that let me overclock fine.

What you should try is changing bit 1 of byte 0 (put sata on PLL2).

For some reason it wont work on my netbook, but maybe it will work for you.

 

Not sure what you've done there. What is the PLL model? Have you TME-unlocked it or done a FSLX pinmod? What software are you using to overclock it?
