PLL Pinmod Overclocking Methods and Examples

I flashed my RAM as DDR2 533 (1.33x multiplier) and it works fine on my overclocked to 266Mhz FSB Lenovo T61.

 

Hello,
I've have some problems when setting my FSB to 333MHZ, I have a CY28410OXC-2 PLL, Datasheet here: www.silabs.com/Support%20Documents/TechnicalDocs/CY28410-2.pdf

In SetFSB setting register 6, last 3 bits to bits 1 1 1 my screen goes crazy and I have to pull the plug.
I don't know how to tell the pll-chip -> output 333 MHZ and make a ratio of FSB:RAM 1:1.

At the moment the cpu e6320 runs at 266 Mhz(x6-x7), the ram at 333 MHz with a ratio of 4:5, do I set the ratio too in the pll?
What does @PUP or Hi-Z in the datasheet mean?

Any help apreciated, I'm looking into these datasheets like a pig into the clockwork.

 

The last 3 bits of byte 6 are only sampled on power-up, they can't be directly changed with setfsb as far as I know.

It doesn't look like setfsb can do anything to help you overclock with that PLL.

Best chance is to try to disconnect FS_A and FS_C from GND and then connect them to FS_B or something that will change them to be sampled as 1 instead of 0.

 

Thanks for the quick reply,
so you mean physically cut the pins and give them 3.3V, so the SMBus samples another value at this register? Perhaps I'will try it, thanks anyway, interesting topic here.

 

Can someone help me and my 6910p to pll pinmod to unlock TME.
I found the instructions here
http://forum.notebookreview.com/hp-...947-guide-6910p-6710b-6510b-overclocking.html
but I can`t read the diagram, i would need some pics how to do this or a good walktrough.

Thanks for your help.

 

Here ya go:

* 6910P schematic
* ics9lprs355 PLL datasheet with pinouts

+ the first page of this thread as a guide. If soldering or reading circuit diagrams isn't your speciality then suggest seek the services of your local mobile phone repair technician.

 

Thanks I got this but I dont understand it quite good. I thought somebody who did this mod could tell me where and what to do.

Thanks anyway man!

 

I've done the analysis of the schematics explaining how to do the mod in http://forum.notebookreview.com/hp-...947-guide-6910p-6710b-6510b-overclocking.html thread. I don't have a 6910P nor has anybody else expanded on those details with reference to the physical machine and components. So you'd be pioneering the effort from that point on if you decide to take up the challenge.

 

Anyone know the PLL to HP1191NR

 

Hey brothers...
does any of you have or know where to find the datasheet of the ICS 9LPRS325CKL?
I have searched everywhere on the web and nothing. I even wrote to IDT but I got no response yet.

Thank you!

 

hi.

I remember i used setfsb to OC my old pentium 4 laptop some years ago.

I was wondering if is also posible to overclock a sandy bridge laptop, the laptop is the XPS 15 (L502X)

if there are chances to OC it, I can take the machine appart again to search the ICS info when I get back from a family trip.

thanks in advance

 

Hello.

I'm make pin mode, hardware:
Acer Aspire 7738G
Intel Core 2 Duo P8700
1066 Bus, (266)
ICS 9LPRS365BKL
RAM: 4GB 1333 + 2GB 1066

Acer Support: Acer Aspire 7738G Notebook Specifications

I make pin mode
I cut oryginal path to pin11.

From 11 pin i put resistor 5k, 10k, 20k, 30, 50, 70, 90k to ground but still I have logic 1.
When is resistor 5k voltage is 0.24 in 11pin but fetfsb have still logic 1.
Screenshot shows it's status on register 9 bit 6, shown as 65h=1100101(binary) bit 6=1, meaning no overclocking

What wrong make i?

I MAKE IT

my tutorial

 

Hi!

I have TME-unlocked my Acer Aspire 5920G:
System Board Rev. G (I think) with ICS9LPRS365BGLF and MY Modded BIOS
Kingston HyperX Gaming Memory 4-4-4-11 667MHz
Intel Core 2 Duo T8300, 800MHz FSB and 45nm technology.
And....a stunning Tuniq TX-3 over it!!

First of all, I haven't disassembled my notebook. Only the back plastic that covers - nearly - everything has been removed. I've just taken a small wire and I have soldered on the second resistor after PIN 4 to the first leg that make contact to the board. Then I have connected it to GND by putting the other side of the cable in the nearest screw hole (the Mini-PCIe one that supposed to be for Intel Robson)
And that's it!

I had trouble soldering the wire on the resistor because it's an SMD one. It's risky because you can short circuit the board.
But now I have a fully functional overclock feature!


2,88GHz with Dual IDA Enabled Rock stable!

 

Congrats, great to hear from another 5920G owner. I'm still wondering why it didn't worked for me with T9500 (800MHz FSB), but it runs just fine with X9100 (1066MHz FSB, downclocked to 800MHz via pin-mod).

*Looking at your sig* You'll need to put some more wires in your LVDS cable and arrange them correctly, in order to get 1440x900. If you want 5920G's schematics, let me know (if you don't have them already)

 

Congrats on TME-unlocking your system. Now 2.88Ghz is a great result however I've seen ppl overclocking T8300s to 3.2Ghz (dual-IDA), so you could (1) slow your RAM timings down with SPDTool/Thaiphoon Burner (2) increase the x13 voltage using Throttlestop and ensure you show the temps in the system tray, then (3) use setfsb to increase the FSB up to the point of CPU and/or thermal instability, then back off 5Mhz to get a stable point.

A overclocked T8300 represents excellent bang-per-buck as a T9300/T9500 will hit an OC wall at ~3.4GHz.

 

I have a Fujitsu AH530 (Arrandale) with SLG8SP585V.

I am referencing Google Translate

With setpll and the no_hw_mod .lut, I can only goto 138mhz bclk. At 139, it locks up.

So I am looking to separate pcie.

That guide is supposedly for the SLG8SP585, but it includes this diagram:

It shows bridging pcie_sata_r/# with cpu_dmi/# and disconnecting cpu_dmi/# from src_1/#

However, here is the SLG8SP585:

It shows that src_1 and sata are shared @ pins 11 and 12, with 13 and 14 being src_2/#


What is the situation? I am not Russian and don't feel confident using a translator to post on their forum. According to the post, they are working with a SLG8SP585 yet posted a diagram showing SLG8SP587V, which seemingly has a different pinout?

I am pretty thrilled to be able to manipulate bclk with setpll. I just need to break past 138bclk now, and most likely modify my SPD for looser timings.

update: looks like the atheros minipcie card is not tolerant of increased pcie. max bclk is 138 with wifi on. disabling, i was able to test incrementally into the high 150's for bclk. somewhere around 150, i started getting video artifacts. dropping bclk down to 140 fixed it, but then I took a big jump from 140 back to the last bclk I benched (158) and it locked up. Looks like something doesn't like the spike in pcie. Not that 150+ was usable anyway because of video artifacts, but it was still going. RAM seemed to be holding on as well, even though I didn't change the spd so it was at cas7 (have an x64 os right now so can't use older thaiphoon burner)

Is definitely good news and makes me eager to attempt separation of pcie.

 

Only way you'll know with 100% confidence which PLL pins are SATA and which are DMI is to get the AH530 schematic: Fujitsu LifeBook AH530 (Discrete) - hobi-elektronika and review the PLL pinout. Unfortunately that free schematic doesn't have the PLL shown. Maybe try this one instead which does show the PLL on the first summary page: http://notebookschematic.com/?tag=fujitsu-ah530-uma-schematic

 

@triturbo: Wow, you can run X9100 on a 5920G! Nice I don't want to spend one more cent on this PC. It's outdated now. And IMHO upgrading it is a waste of money (and time). Better buy a new beast

@nando4: Well, I tried clocking it more and this is what I've achieved

Very stable!

Even if I slow the timing of RAM, putting more than 504/760 in SetFSB will reboot the system itself.

 

Nice.. but I believe you could overclock further. Necessary is slowing down the RAM timings and increasing the x13 voltage to the max using Throttlestop then ramping up the FSB in setfsb until it's unstable. If you are already at max voltage, then consider a +0.1V or +0.2V CPU voltmod to increase voltage http://forum.notebookreview.com/har...90696-bsel-mod-socket-p-explained-photos.html . Before doing this check the temps with the current overclock/voltage and try to estimate how much margin you have to play with. You'd want max ~93 degrees at full load to give you a decent margain before the CPU hits Tjmax (100/105) degrees where the system would switch itself off to prevent overheating.

 

Well, with the stock voltage (1.2125v) and IntelBurnTest the notebook turns itself off because it reaches 105°C. Even with no overclock and a repaste. Never had problems 5-6 months ago...maybe the heatpipes are broken.

 

Well it's just that I really like the design and that it's 16:10. I HATE 16:9

 

Hey, I have a laptop Compal KHLB2, how to tweak it Core2Duo P8600 processor?

I found on the PLL ICS9 LPRS387BKLF

Specification of my laptop:

Intel Core 2 Duo P8600
PM45 Motherboard
4GB RAM DDR3 1066Mhz
Graphics ATI Mobility HD4650 512MB GDDR3
Seagate Momentus 320GB 7200rpm

Is it enough to where the cut the pin 14 according to the following schedule and will work?





please help

 

Help someone?

 

Yes that should work.
But you will have to make sure you connect that pin to GND.


It looks like I might need to update the table.

Also I have an idea about overclocking a sandy bridge system with a PLL pin mod:
http://forum.notebookreview.com/sag...-sandy-bridge-pll-pin-mod-overclock-idea.html

 

So, just as the cut the pin 14 and connecting the cable to GND? there must be a resistor on the cable?

I found a forum on the Italian way of unlocking the PLL ICS9 LPRS397 DKLF and OC P8600, is said to be the twin to my ICS 9LPRS387 BKLF. Does that make it look like the picture below and it should work?


PLL PinMod p8600 @ 3ghz

 

Yes a resistor is a good idea, just take your time when you're doing this mod. Be really careful.

 

Ok, thanks a lot for your help

 

+1. The m11xR1 folks that just disconnected the TME pin found the logic floats between 0 and 1. To get it to be a definite zero requires grounding that pin.

 

Can someone help me with pll mod?

MY PLL is slg8sp513v - model Samsung R522 montevina. CPU P9700

Here is the datasheet: Slg8sp513v.pdf - download. Darmowy hosting plików.

What should I do first?

 

hello.
I have Gateway TA7 and as I found (from internet not itself) he has PLL ICS9LPRS365--but when I chose this PLL from SetFSB--setFSB button is locked. I already write bytes to PLL control--but nothing--button still locked.
what need to do?
(it's GM965 chipset and Intel T4400 2.2GHz)


upd.
or I need PLL-pin mod (that unlock overclocking)?

also how to use setPLL program? when I do setpll -read then myPLL create with empty BLCK's and when 'setpll -preview mypll 210' (for sample) then receive error 'RW is not internal or external command that executing program (translated from russian).
(next line)
setPLL ERROR: No 210Mhz entry in [BLCK] section of mypll.lut'

 

Hi i have Acer 6920 clock generator ICS9LPRS365BGLF with TME-unlock All worked fine i overlocking my system from 2.4 to 2.8 but now i overlocked gpu too. I have NVIDIA 9500M GS. If is GPU overlocked i cant overlock the cpu becasue system freeze. If gpu isnt overlocked all is ok. SO i think setfsb automaticaly change the pcie frequency. But in bios a cant choose pcie frequncy. Its my mind i dont know if is true because all monitoring programs show PCIE 16x but not frequency.
can anyone help me???

 

Hello all. I would like to intrude with my own question as well if anyone has any insight they would like to offer. I would like to overclock my laptop but can't seem to find something for my PLL. The specifications are as follows:

Laptop Model:	VGN-AR730E
Motherboard: (I believe)	MBX-176 (scribd.com/doc/81419562/Sony-Vaio-Vgn-Ar71mr-Mbx-176-m610-rev2-0)
Chipset:	Intel PM965
PLL:	ICS9LPR358YGLFT
Processor:	Intel T8100 Core 2 Duo 2.1GHz

My problem is that SetFSB doesn't have such an odd PPL and I can't find anything on the internet regarding it (except schematics and other engineering resources). I would like to try overclocking through software but, even though I could, I don't want to solder or flash the bios; especially since I'm not sure how far I could push it before heat is an issue. I have tried the ICS9PLRS355BGLF PLL (SetFSB's closest) but it can only read as trying to set it without modifications immediately locks the system up. If anyone can offer any insight I would greatly appreciate it. Thanks for your time.


EDIT- Actually, I think the TME might be locked so software isn't looking like an option. Flashing an unlocked BIOS rom wouldn't help if the PLL is hardware locked, right? If this is the case then soldering is the only option?

EDIT2- If I were so ambitious as to try pinmodding the PPL would I connect pin 4 (PCI2/TME) to the ground (pins 15, 19, 23, 29, etc.)? I would rather do a BIOS flash first though if that would work (with TME).

 

Hi i have now very big problem my notebook i THINK IS DEAD. I overlocked the cpu and then a slowly overlock the gpu and testing but the notebok freeze so i tornet off the notebook. Then when i set power on the notebook start but dysplay is BLACK and the hdd led responds if DVD rom is working. What is but? CAN YOU HELP ME PLEASE ENYBODY. It isnt funny :-((((. Do you know any body what is dead? I changed ram cpu but it isnt dead. I think dead are maybe pll chip or Northbridge or southbridge.
HELP ME PLEASE. THANKS

ACER ASPIRE 6920, T7500, 4GB RAM, ICS9LPRS365BGL, NVIDIA 9500M GS

 

I reset cmos and clean the motheboard but dont work its same have you any idea?

 

@reptile

if you pinmodded something, try undo the mod and revert it to the stock status.
look for fuses at the motherboard, and check them using a multimeter.
if there is a broken fuse, try replace or bridge it.
unplug the laptop from wall and battery and remove cmos battery, and leave it as it is for two hours, then assembly it again and turn it on.

if it still broken, it looks like you will need a new motherboard or laptop :/

GL

 

Ok i Willl Try it Thanks :-(

 

I Try it and fuses is Ok and all looks ok but dont work

 

If you were overclocking the GPU, my limited experience would say that's the problem. Since it's a laptop the display is probably connected to the GPU, which you can't just remove. Maybe one of the adjustments you made permanently damaged or changed an internal setting of the GPU. I would say, though it's a really long long-shot, try connecting other displays to the other outputs on the GPU (I assume that has at least VGA). Otherwise maybe see if there are ways of hardware resetting it. I'm just grasping at straws here, though. I'm not well experienced with this stuff.

Another highly unlikely option would be to use another computer to have an OS already installed and configured on the HDD so all it has to do is boot up. Then remotely login to it and revert your changes. Of course, that assumes it will successfully boot. You could try making a throw-away installation of Windows with autologin and something like LogMeIn.

 

Ok thanks so i connect ntb to crt screen. So ntb when is off and i connect the crt cable to ntb the crt screen shutdown and the green led on crt shut off too. when i turn on the ntb is same. Ntb i tested without hdd and problem is same.

 

I didn't think a different display would really work as that would work only if the problem was with the LCD's connection/port. Does it seem like it is at least booting or is there no activity after the first few (~5) seconds?

 

System dont booting. I Turn on ntb and the hdd led respond cdrom activity. Fun turn on too thats all.

 

Well perhaps someone with experience can give you pointers on actually troubleshooting/resetting/flashing the hardware but sounds to me like you might need a new motherboard, unfortunately. You could try selling the old one on ebay to some ambitious fixer.



On an unrelated note, I could still use any pointers on my own question last page if anyone can offer any.

Hello.
How you know that OS system don't boot?
As I understand your 9500GS is broken now. Usually Acer 6920/30G (G-index, right?) have mxm II connection for video card and you can try to repair video card or buy another (like 9600GT) or try to sell laptop.

How you do pin mod? I have the same PLL (named on motherboard RTM875-606, but in datasheet that I found (overall version) it's named as ICSLPRS365, as I remember).

 

Thanks for reply. I think motheboard is dead my gpu will be good. I testet the motheboard without rams and all is same.Without rams dont beep. Noteboard dosnt load the bios. Notebook unresponsive if i push any buttons.I tested without gpu and all is same. Notebook only responds if in cdrom is any dvd/cd then blinking the hdd led. I have pll unlocked with TME mod. 4 pin groun with 10 or 20Kohm to GND.I do not remember the exact value. PLL is ICS9LPRS365BGL. I think the nortbrith is dead because if i rymember it louads rams and pci express port....... I have Acer 6920 without G but a think is same. In bios was Acer 6920 and all another programs showed 6920 without G too. I'm thinking to buy nothebouard from acer 6935G. I think its same but improved. This motheboard have DDR3 Rams and suport better CPU with 1066 fsb.

 

Sorry, my English is bad and I don't understand exactly what you mean. But trying all cases (without RAM, GPU etc.) is good idea.
As I know first problem if no displaying it's problem with GPU. (if HDD indicator is blinking and DVD works). You also can wait when laptop load OS around 2-5 minutes. (or may be your OS have malfunction when your laptop freeze first time and OS restarted not normally).
When you overclock GPU you use program as Rivatuner etc. or you flashed video bios?
If you'll buy m/board from 6935G then may be you need some little modification of your laptop bottom or overall case. (or may be no need do this). But this upgrade will be really good.

 

I had running notebook all night and prablem is same. keyboard dont work only power button work. Motheboard is dead bios dont load so i want to buy the 6935 motheboard. Now i describe how problem happened. So like first i had overlocked bios on my gpu. Then i overlocking my cpu byt if i set only 1 fsb more (in setfsb programm) my computer freeze I tried it several times and sometimes my system dont freeze but when i running the MAFIA 2 GAME my notebook freeze (but if i wait 2 minutes system show this error :"Display driver stopped responding and has recovered" and then i see green artefacts in the game so i turnet off the notebook. So i then put my original bios to gpu with not overlocking values) and then i overlocked the cpu from 2.4GHZ DUAL IDA to 2.8GHZ DUAL IDA Stable. Then i overlocking slowly in nvidia panel the gpu and tested in MAFIA 2 GAME but at once the system freeze so i tuned off notebook and now i have dead the motheboard.

 

Hello again. After my last post got no response I went ahead and tried flashing a modded bios (Hippotek's R2090J8 modded by KIZWAN) and it worked fine. I can now adjust things like the CPU temp fan thresholds and enable virtualization but nothing about clocking comes up. I assume it's because (I think) the PLL is locked. As in my other post, my laptop's specs are:

Laptop Model:	VGN-AR730E
Motherboard: (I believe)	MBX-176 (scribd.com/doc/81419562/Sony-Vaio-Vgn-Ar71mr-Mbx-176-m610-rev2-0)
Chipset:	Intel PM965
PLL:	ICS9LPR358YGLFT
Processor:	Intel T8100 Core 2 Duo 2.1GHz Penryn

Using setFSB with ICS9LPRS355BGLF (the closest to mine), it didn't crash on "Get FSB" and after setting bit 2 of register 2 to 0 as per this guide's TME_READBACK check, the system locked up. I assume this means my board would require an FSL mod to overclock, right? Looking at the PLL diagram on page 3 of the motherboard schematic, however, it specifically says for the PCI2_TME
"pin4 setting 0= Overclocking of CPU and SRC Allowed
1= Overclocking of CPU and SRC NOT allowed"
Furthermore, for the CPU block it says Merom yet, as listed many places including in CPU-Z, mine is a Penryn. So there's quite a few seeming inconsistencies.

Also, as a side note I have been running Burn In 2008 in CPU Burn In mode and the processor core temps are only hitting 57 Celsius so I think it has a little clearance for a moderate OC.

Can anyone offer me any hints or tips?

 

There were many notebooks that came with a merom CPU and could be upgraded to a Penryn, so that part is fine.

I would go for the fslx mod if I were in your place because if you do the tme mod then your notebook would probably not turn on. Though nothing stops you from testing that.

Also your temps are great, I wouldn't worry about anything under 85C myself.


The nice thing about the fslx mod is that you don't have to mess with software.

 

Raptile
You already tested GPU in another laptop?
Motherboard really can be damaged with this method?

This is my RTM875.


Just need to short pin4 to ground with 10-20k resister?

 

Thanks for the reply. So am I correct in understanding that by setting FSLB (pin 57) to low, that it locks the frequency at 266 instead of 200 on the hardware level? Is it not possible to have the variable option in bios to overclock when wanted then underclock later to save power or after the mod would I be able to change the multiplier? I'm really thinking about not doing it because this is my only laptop right now and it would be kind of irresponsible to risk it during the semester just to be able to run one class' software.

EDIT- Also, it seems someone blatantly ripped off this thread: conlocso: PLL Pinmod Overclocking Methods and Examples
