PLL Pinmod Overclocking Methods and Examples

I may give the Hard mod a try, I have a T5555 166 FSB.

I always assumed it was the CPU setting the FSB to 167, as I've seen reports of others who have upgraded CPU's in HP DV68xx's to 200 mhz FSB, and not had to hard mod.

Any way, it looks like I'd need to change FSA(PIN 17) from 1 to 0, so how would I do this?

 

Yes, the cpu does determine the FSB. But with newer intel chipsets if you try to pin mod the CPU it will get locked to the lowest multi.

The same way that I set my TME pin to 0 in the first post.

You have to disconnect the pin from the motherboard, then connect it to GND.

If you take a photo of your PLL, we may be able to spot a resistor that is connected to the pin.

If you do find a resistor connected to the pin, then all you have to do is remove the resistor. Then connect the pin to GND with another resistor (or use the same one).

 

I dont need to, my ram is specced at 1066Mhz DDR2 - 5-5-5-15 and its running greatly under the specs around 880Mhz DDR2 5-5-5-15 when pll in modded state.

 

Please tell me where you got 1066mhz DDR2?

Please please please

 

There was sometime ago 1066Mhz 2x2Gb kits in Jimm's PC Store, not shure are they anymore there since aviability is kind of well poor, these chips are binned really high.

Edit : Oh btw, Jimm's PC is finnish online pc store not shure do they ship international.
Edit : Checked and they are not anymore in lists of Jimm's PC. Guess the aviability issue, anyway my kit is A-DATA SODIMM DDR2 1066 2X2GB 128MX8 CL5.

 

Thanks I'll keep an eye out for it.

There was a thread a while ago debating whether it even existed.

I wish I had some, now you gave me some hope that I will find it

 

Those kits are really hard to find, maybe you should ask directly from A-Data if these kits are still manufactured.

 

Ok, does that mean if I Pin mod my FSB, I'll be stuck at 6x?

Not sure how this will look, but........

 

If you pin mod the CPU, yes it will be stuck at 6x.

If you pin mod the PLL, it will not be stuck at 6x.
That is why this thread is about PLL mods.

That is a very good quality photo.

I will just look at it for a few mins to see what the best option is.

 

looks like pin 17 is connected to a resistor of some sort.

hard to tell the best way to do this.

I would wait to see what nando4 has to say about this one.

 

I'm in the same boat. i need to go from 166 -> 200 and my PLL looks identical

 

I think since im unable to get it to boot properly, ill sell this laptop and buy another one with comfirmed oc ability.

Need just put some other cpu into this laptop first so im able to use my T9500 on new machine since its ocing beast.

 

Looks like two resistors mounted right next to each other. More clear when viewing with the eye. The idea here being to lift the left side of that resistor leading from pin17, attach a tiny lead to it and run it to GND, placing some insulation tape below the resistor so it can sit on it. That would set pin17 to be logic 0.

I have the same thing on a broken tecra M9.

The resistor on my tecra M9 is actually two resistors joined together.
So you can't take them off one by one. Makes it hard to work with.

I see this more and more lately. Not very good for our purpose.

 

so i have the same pll chip as ibanezbass so does this mean i set it to RTM876-660 and it will work?

 

It may work. But some PLLs have TME mode enabled, this means no software overclocking without a pin mod first.

Try RTM876-660, tell me your results and maybe we can get it working

Sorry I dont know what PLL that notebook has.
Just download setfsb from here:
http://www13.plala.or.jp/setfsb/

Try every available clock generator in setfsb, maybe one will work.

 

well i have been messing around with set fsb and tryed a few dif pll but none of them seem to change anything on cpuz... what now?

 

can you select RTM876-660 in setfsb.
Then click on the diagnosis tab, then click "getfsb".

Then please post a screenshot here.

I think it's likely you also have TME enabled. If so, you will need to do a pin mod to overclock.

 

ok i put up the screen shots i put the cpuz and my temps on there too wasnt sure if u wanted them too...

 

Looks like you do have TME mode enabled (no overclocking without pinmod).

And I dont have the datasheet for your PLL. Without it, I have no idea how you can overclock.

I will take another look to see if I can find a simmilar datasheet, but I dont think I will find it.

You could maybe send an email to realtek and ask for the datasheet for your PLL. Doubt they would give it to you, but I see no other way.

 

can you help me understand TME? is there a way to take TME off? what if i install a dif OS? or is it in the chip?

 

TME is in the PLL chip. Its isnt something that software will take off

 

I can confirm the Pin_Mod works for the RTM875t-606(Realtek Clock Generator).

Thanks go to Moral_Hazard and Nando4.

Also, Flipfire for the Undervolting Guide.

Plus, all those who helped.

It seem that this is the first documented OC using the RTM875t-606, and we don't have a DataSheet for it, so I'm going to make a new thread to gather info.

 

Nice one, I'm definatly going to subscribe to your thread.

So did you pull the PCI2 pin low? Or did you do the FSL pin mod?

 

wheres a ground that i can run the pin 17 lead to?

 

hello !! I have seen your locked laptops overclocking thread.

I've tried to OC my vaio with setFSB but it made no changes at all and it cudnt shut down . later when i removed the battery it worked normal from the next boot. mayb bcos i was unable to identify the correct PLL. I couldnt find it anywhere else!!

looks like my vaio is locked and i have no option of OC in BIOS nor an update available to BIOS.

SUGGEST ME THE BEST AND EASIEST METHOD AMONG ALL THOSE METHODS THAT BEST WORKS AND STILL TO BE ON SAFER SIDE (not bricking my laptop cos i have no money to buy onemore if this is gone and i m a student so i need it regularly).

also tell me whats PLL for this motherboard!! thank you loads!!


Vaio VGN-NR17G

core 2 duo T5450 1.66 ghz
FSB=166mhz
PCI=33mhz (i guess)
intel GM965, x3100 IGP
2 GB RAM DDR-2 667 mhz
Motherboard manufacturer : Phoenix

 

Use SetFSB->Click Diagnosis->Chose PLL diagnosis in the Clock Generator field-> Check Ultra->Click GetFSB.

Get a Screen Shot of that and Post it.

 

so this is what happened !!...

In setFSB i tried many PLLs but i got error except for 2 PLLs

they are attached here!!..

i tried to change both the sliders and clicked setFSB. i dint see any change but after shutting down the system was still using the power it dint completely turn off. after removing the battery i got it normal . Also CPU-z detects my CPU as T5550 but mine is actually T5450 Core 2 duo.

 

You have TME mode enabled. Means no overclocking until you do the same mod that I did on the first page of this thread.

You need to find your PLL first:
http://forum.notebookreview.com/showthread.php?t=429383

 

I found 2 PLLs showing my lap's specs but they revert back to actual numericals when i tried to change them and click setFSB.

and using si-sandra i dint get " system clockgenerator" tab under Mainboard details at all. Only BIOS version,manufacturer, ID and crap info were seen

 

That happens because TME mode is enabled. When you disable TME mode, the numbers will stick.


On a side note, got a T8100 to 2.7ghz today

 

11 D3 That should tell us what your PLL is, however I've not seen that one before, and don't know what it is.

As you seem to have TME enabled, your going to have to Open your Notebook to be able to OC, if you do, please take a few Pictures and let us know what chip you have.

 

i think i have to give up

 

thats nice!!... not all core 2 duos T5450s have same PPL ? ... does it depend on manufacturer or chip architecture?

 

It depends on what the manufacturer decided to use on your motherboard.

Sorry that it doesn't work for you

You might want to try clockgen, but it's a long shot.

Otherwise this is something you should do (if you're not already doing it):

Hello, i have opened my notebook and found RTM875N-606 clockgen chip. I also found one threat in which this chip is mentioned. But this is as far as I got. It seems to be a problem getting a datasheet. Link to a thread: http://www.aspireoneuser.com/forum/...&sid=afe0f0aedee552d3395709605225bea0#p102418

Some help please

 

@au9879, Here is how to overclock it:
http://forum.notebookreview.com/showthread.php?t=429717

 

I have a different chip - mine is RTM875N-606, but your link is about RTM875t-606.

Pinout is totaly different and my chip is square shape...

 

Do you have a pinout for your chip?

 

No - and nobody can find it . I have googled like one hour and nothing except a few chinese pages, but even there is no datasheet or pinout for the chip.

Anyways I think its a little to complicated for me, to remove those really thiny resistors... to risky.

 

square 64 pin MLF package, I'd say you need to Ground PIN 11:

Before that try:

Click 00h set bit 2 to 1->Click Update->Click Apply

If your system keeps Running like it does not care, then it's Safe to do the Hardware Mod.

If your system FAILS..............STOP, you need to try and setup the PIN17/18 Pin Config (I'll add a table for this later if we have anyone that needs it, post a reply to this topic.)

After the Mod.

Step 4. Run SetFSB->Click Diagnosis->Chose RTM875t-587->Click GetFSB

Click 00h change bit 2 to 1->Hit Update->Hit Apply

Move the Top slider to the FSB/RAM timing you want to test->Hit SetFSB

 

If I select PLL diagnosis and GET fsb, than I can change bit 2 of 00h from 0 to 1 and nothing happens when I click Update. So its safe to do hardware mod...

But will the clockgen for RTM875t-587 work after I do the mod? Because now if I select this clockgen i get PLL ID error...

 

ID Error? That's odd, are you sure your PLL is Realtek?

 

Pretty sure, yes:

Have you find the PLL of that notebook ?

Did you try some clock generator in setfsb to overclock the M6400 ?

 

Hi,

because this is my first post I would like to introduce myself a little bit.
My name is Tom, I'm from germany and want to overclock my HP DV6-1200 notebook.

I red all the stuff about tmpreadback-pin / PLL2-registersettings of you genies. YES GENIES! Because all you sayd is absolutely correct.

After FieroGT got his Dell1525 working and Abo supports ICS9LPRS355 of HP 2510P in setfsb I pray to the computer-god and follow your instructions yesterday evening.

I dont want to do the +66Mhz FSB step with bsel-mod / FSLB but the softmod via setfsb and 1MHz increments. I will attache you every photo I made, hoping somebody can use it for his own mods.

As you can see the tmp_readback register 9 ist NOW 25 = 0 = enable oc!!!
After that I applied a "0" to the PCI register 2 = 0 = output disabled!!!

BUT - it doesnt matter what I change to the MHz sliders (+0.5 / +2.5 / +10) the system always freezes and screen goes black. So my newbie question to you genies is: WHAT did I wrong??? Is it the ICS9LPRS355.B.L.K. instead of B.G.L.F.?

I apprechiate for every response.

Bye
Tom

 

setfsb's ICS9LPRS355BGLF was written specifically to a work with the 2510P with TME enabled. Since you don't have TME enabled, the results could be unpredictable as you clearly show. I also believe it's the only TME enabled PLL that still works with setfsb.

Try a different similar series PLL instead, eg: ICS9LPRS365xxx. Bytes OD and OE control the FSB if you want to just change those manually. Some samples as shown in the PLL_t entry here. Eg: 0D=48, OE=67 sets 183Mhz FSB, which would be a downclock in your case.

 

Hi nando4,

was the implementation of ICS9LPRS355xxx tmp_enable from beginning or should I give another/older version of setfsb a try? The first post of this thread uses 2.2.113.85e I use 2.2.13 4.98.

Im absolutely shure I disconnected Pin11 of the pll. But I do not definitifly know if the grounding works. "moral hazard" wrote: dissconnecting w/o grounding wont boot the notebook.

Because mine boots and setfsb starts, could there something be wrong-wired?
Is grounding=0 different to only-disconnecting=0?

Thanks
Tom

 

GND=0.

But you may have an IPD, so that would let your notebook boot.
I think your hardware mod is good.

You should just try what Nando suggested:

Also try using my PLL: ICS9LPR501SGLF
