PLL Pinmod Overclocking Methods and Examples

+1. Going 200->266 overlock very likely needing spdtool or Thaiphoon burner to set slower 333/667Mhz SPDtable RAM entries as it would be operating at 443/888Mhz. CPU too is getting a hefty overclock so might need more voltage as a pinmod.

 

I guess the pinmod is not needed, because the cpu is specified for 266mhz. Maybe the ram cant handle it, but i think its specified for 800 and maybe it will work like that. if not i will change the timings.

Hope that the P7350 will work and that the PLL mod will work and not crash my notebook.

 

P7350 is a 266Mhz CPU. PM965 max BSEL is 200Mhz. If the CPU won't accept the 200Mhz BSEL, then need to provide a 266Mhz BSEL to 'trick' it into operation while at the same time the rest of the PM965 chipset can't see a 266Mhz BSEL, else it will not post. The way to achieve both would be to hardwire the BSEL pin that sets 266Mhz, yet isolate it from the rest of the system. If that boots, it would running at 200Mhz. To get it running at 266Mhz would then require SPDTable mod to slow down ram AND FSLb PLL mod to increase the FSB to 266Mhz. A bit of work.

Which is why a 45nm 800Mhz CPU like T6400/T6600 would be a better candidate to begin with imho. They run pretty low voltage and can be bought at pretty good prices. A T9300/T9500 better, but more costly.

 

Just a correction to moral hazard, i run my X9000 in old Clevo M570RU, PLL mod to 266FSB = 3724MHz. M860TU is already MV Platform.

 

Thanks for that, I've have corrected it now

 

That's very impressive. What voltage are you running and how are the temps?

 

Hy,
I have read the technical data of this post and I am very confused.
I have a dell xps m1730 with a T7700 cpu. Can I BSEL mode or pin mode my cpu?

also I have no ideea where the PLL chip is on the motherboard.

if I mode my cpu, will be a problem with the RAM modules ?

 

Sorry, but any pin mod done to your CPU would only slow it down.

The max FSB that your chipset supports is 800mhz, the T7700 has an 800mhz fsb. You could BSEL mod the FSB to 667mhz, but no point in doing that.

You should try to find the PLL.

 

Thank you for your time. probably when I will buy an X7900 I will open it and find the PLL chip.

 

I flashed my ram to with information from a 800MHZ module is this good enough or do I need to actually change the 333MHZ SPD table to have slower timings.

I'm using the P965 chipset (800 Bus/667 RAM) and want to go to 1066/8xx using method 3.

 

Flashing your RAM with information from a 800Mhz module just gives you a 400Mhz SPDTable entry. The 333Mhz SPDTable entry will be as before and will be the one used to boot your system. The 333Mhz SPDtable entry needs slower timings to provide stability you apply the FSLx 800Mhz->1066Mhz FSB overclock (333/667->444/888Mhz RAM timings).

 

Do I need to change anything else besides the tCL from 5.0T to 6.0T?



Also for the PLL mod do you think this is the correct ground? (39 Green)

Clock gen data sheet

http://www.idt.com/products/getDoc.cfm?docID=18712578



data capture from setfsb 2.3.144.108


Register data from CPUZ 1.54

I try mod jump pin 10 (FSLA) to GND (R2.2K pulldown) but not work
system can't boot

 

TME is disabled, looks like you probably don't need a pin mod.

I would try all of the similar PLLs in setfsb, if none work, email abo (creator of setfsb), show him the screenshot and the datasheet, he should add support.

If abo can't help, you can try connecting pin 10 (FSLA) to GND. That should take your FSB to 200mhz.

Pin 10 seems to be connected to a resistor, I would lift one leg of the resistor and connect it to GND.

 

Bit 9=25h=100101b. So TME_Readback bit 6=0, TME isn't set. Only problem is the datasheet doesn't give info on how to program the PLL. The idea of doing a FSLx PLL pinmod is sound, but would need to decrease RAM timings to accomodate for it.

 

Sorry if OT but where did you get SetFSB 2.3.144.108? I downloaded a copy and it works but asks for a code. I did not have a code so I hit ok and then received a message about how it was a trial and I needed to buy but there was nowhere to go purchase once the prog starts up.

 

hey guys, im thinking about trying a pinmod. are there any good soldering tips that will fit a cheap 40 watt iron? i bought one on ebay but im not sure if its small enough.

 

You have to have on mind that if You rise fsb from 165 to 200 by pll mod cpu v migh be insufficient. If You check this review of atom d510 matherboard : ZOTAC NM10-DTX WiFi (NM10-Express) Motherboard w/ Atom D510 CPU BIOS and Overclocking :: TweakTown, You will see that overclocking this board even with option in bios wasn't impresive at all. I suspect that they didnt rise cpu voltage at all. And HWBOT have only 3 results above 2000MHz (all about 2105MHz) for this processor and one of them was done on LN2. It looks like this atom isnt overclocking friendly.

 

Hello all,

I have a Dell Inspiron 1545 with a Pentium Dual Core T4300.
My pll is SLG8SP513V

TME is enabled, I'm wondering if anyone has had any success with the same pll. I will post a screen shot of setfsb. To access my pll, all I need to do is open a panel on the bottom. I'm willing to take my first shot ever soldering anything, as long as its not too risky. I can take a picture of the pll chip if necessary.

EDIT:

 

People have asked about this pll before, if I remember correctly, nobody can find the datasheet. Though I suggest you search this forum for "SLG8SP513V" and see if someone has managed to pin mod it.

 

See info on how to TME-unlock the SLG8SP513V PLL. Please port your results if attempting this pinmod. Lots of Dell owners could benefit with a freebie performance upgrade.

 

Thank you for the response. I had just been using google.

Thanks for the link. I'll certainly show my results here.

I just took off the bottom panel, and couldn't spot R124 or R122. Maybe I missed them, or need to further disassemble.

I don't know if I'm way off or not, I'm under the impression that I can try taking a pencil to the top of the resistor on R124 to disable it, and make a line between the R122 pads for a connection. I think I'll be trying this before any soldering.

Edit:
Still can't seem to find R124 nor R122. This time I took out my ram, and peeled a black sticker off the mobo. The edge of the sticker is a little bent, and there is some grease on it. I hope I haven't effected anything. There is a smaller black sticker beneath the wifi card too, I'll look under that one as soon as I find out I'm not ruining anything. I suppose I'll post on that Asus forum, asking where people found theirs. It'll be a bummer if I have to remove the mobo.

 

Well I took pretty much everything apart, and found r124 + r122. Both seemed to have resistors on them though. So I didn't remove the one from r124, better safe than sorry. Now the question is if I am correct, and both had resistors.

R124 and maybe R123 were both side by side, than to their right was two resistors also side by side. I figure that means the left one is R124 and the right R123.

R122 was with 6 other codes contained in white lines, which also had 7 places all with resistors. In the list of codes, R122 was top left, so I figure was also top left out of the 7 resistors. I don't know if they were all resistors, but certainly all covered by some type of box.

According to the post on the Acer forum, you have to remove the resistor from R124 and place it on R122. Obviously there's a difference with my dell. I'd like to know if it would be wise to open this up once more, and remove the resistor from R124, leaving R122 alone. Also if it can be done with just some tweezers.

 

Could anybody help?
My NB is Quanta TW8,PM45 Chipset,T9400 CPU.PLL is SLG8SP513V,and it was TME lock enable.I have learn some posts that tells how to unlock the TME mode,at last I connect pin 11(TME) to GND,and setfsb shows that bit 09 is 25,means that TME is disable,but I still can't OC.By selecting slg8sp513v,333 MHz or 200 MHz FSB,the NB crashed or reboot.By selecting SLG505YC56DT SLG505YC264BT and SLG505YC256BT,it freezed or crashed. anyone konw why?

 

Are they the only FSB options setfsb gives? Either will be problematic. 333Mhz is a subtantial increase from 266 so your CPU would now overclocked 2.53->3.16Ghz and your RAM would be overclocked 800->1000Mhz. The CPU would need BSEL voltmods and/or RMClock set to higher voltages for stable operation. The RAM would need slower RAM timings to function.

200Mhz would probably downclock your system too much to work. My 2510P downclocked from 133->110. Any less and the x3100 video doesn't like it.

 

Thx for reply,the pll doesn't give 1 MHz increase opinion，only 200->266>333->400,
select 200 or 333 may cause comuter crash,no matter the RAM is 800 or 667.i use Rmclock to set the max multiplier to 6 @0.95v,then set FSB to 333Mhz,it still reboot.

 

As you have seen,several days ago I have done Quanta TW8 TME MOD with SLG8SP513V,but didn't success.
At last,I change to do the BSEL MOD
Here is a part of the PLL datasheet of Quanta TW8,
there is a resistor R219 (2.2K) leading off the Pin64,so connect Pin 64 to GND will set fsb from 200 to 266,and it work
I have bought a pentium dual core T4500,and now it works at 3.06GHz.The ram runs at 443MHz(DDR2 887)

 

That's a great result, added to the table on the first page.

 

hi i have an 2710p laptop i read all posts...i dont want to open the laptop it has guarantee..so i tried with setfsb and pll of 2510p .
i cant change byte 17 and 18 ...i change 09 , changed ok...but 17,18,13,14 is only bytes i cant change....all other i can. why this happens? what i must to do to enable change these bytes?

 

2710P thread has had a go at software overclocking with no success. Appears then you'd need either a TME-unlock or a FSLx pinmod to be able to successfully overclock a 2710P. Perhaps worth waiting for the warranty to expire?

 

i have 2 more year warranty so is not worth...

 

I discovered the PLL of the Aspire 5940g/7740g/8940g notebooks.It's ICS9LRS3199AKLFT.IDT website doesnt even have it listed yet (I emailed them)

 

abo found out it's the same pll as in ASUS-N61JQ so Acer Aspire 5940/7740/8940 now work!!!

 

Hello!

I got a Thinkpad X61 with T7300 CPU and Intel GM965 Chipset, the PLL chip is called: SLG8LP564, but SetFSB doesn't support it. Does anybody have an idea what do to for overclock?

 

Could hunt for the PLL datasheet so could do a FSLx pinmod along + slower RAM timings + BSEL voltage mod as described on the first page to go from 200->266Mhz FSB. T7300-2.0 would then run at 2.66Ghz.

 

Hey guys,

I've got a Dell XPS M1330, with the T7300 and the chipset i believe is the GM965 ( With integrated graphics), and i just recently stumbled on this thread whilst searching for a way to overclock the system. I tried a few ways... Tried looking at the registers and adjusting one by one hoping that one of them controlled the FSB.
Which Clock Gen would it be? And how can i go around to overclocking it?

 

XPS M1330 FSLx pinmod overclock is linked on the table on the first post.

 

^ right:
http://forum.notebookreview.com/har...socket-p-explained-photos-35.html#post6360837

 

So I am going to have to do some soldering to do the pin mod? or is there another way?
Thanks for the info there, BTW i found this thread from you moral hazard on HWBOT ... Pretty cool

 

The datasheet is here:
http://www.silego.com/uploads/Products/product_66/xSLG8LP550r10_05152007.pdf

If you can upload a screenshot of setfsb with the diagnosis tab, I can tell you if you need a pinmod.

Or you can just check if bit 7 of register 15 is 1 (overclocking disabled, need pinmod) or 0 (don't need a pinmod).

 

I am not quite sure if im doing something wrong but it has no value...

 

Did you press getfsb?

If you did and it still doesn't show the registers, try this

http://forum.notebookreview.com/alienware-m17x/495203-how-oc-m17x-r2s-920xm-940xm-using-setfsb.html

 

I did click getfsb and i had tried changing the font size previously, with the same result. Any ideas?

 

I can't think of anything.
Maybe try clockgen.

 

Tried it, It wont let me change any settings or provide anything to change it with. I think it might be a different PLL chip or something

 

Well I guess you would have to open up the notebook and check.
Probably needs the pinmod anyway.

 

Just checked the specs on the system that was overclocked, it had the nvidia graphics, which has a different motherboard. So Im guessing its a different PLL chip.

 

Darth_nVader told how to oc rtm875t-606 here

and now I have another Quanta TW8,pll is rtm875n-606,and have done tme mod,remove the resistor connected to pin11(tme) and then to GND.Now select rtm875t-587,bit09 is 25,bit00 is 41,and bit07=1E,which is the same as Darth_nVader writed.But update bit00 to 47(Click 00h set bit 2 to 1) system crash.From the url above,Darth_nVader said

How can I do the config?

 

hi! I'm really glad to have found this thread!!

I have the PLL ICS9LPRS365BGLF, and downloaded the pdf via datasheet4u as the other links in this thread no longer works.

The good news is free version of setfsb supports my PLL.

Bad news is it's TME enabled, as I read the register 9 and it says 65 in dec.

So I guess my only savior is to pin-mod it, since I don't think I can figure out how to bypass it via setfsb.

Since the datasheet said it's sampled first (pin4) then is used to set PCI, i'm somewhat scared to just cut it off, what should I do? Where can I reconnect the pin to?

Here's a photo I've just taken of the PLL and hopefully it's pin4's resistor...

any help would be much appreciated !!

should've tried the official website for datasheet.

 

Looks like pin4 goes to that resistor, but it seems to also go down a hole.

First thing I would try is just removing that resistor and booting.
If that doesn't work, you might have to cut the track comming from the pin and then connect the pin to GND.

Maybe Nando will reply with a better idea?
