PLL Pinmod Overclocking Methods and Examples

once again - me

the 667 dump looks different.
Previous attached dump was loaded via [open].
Now - I attach you the [open dump] summary from the browser window.
Looks much better to me.

Maybe a bug, or trial limitation???

Bye
Tom

 

Sorry that it didn't work.

Yes it looks like there is a bug with win7 + thaiphoon burner.

I have a problem with it too.

Try using winxp if you can.

This time when you try it, just use the editor and try to increase the Cas latency.

 

Anyone here had success pinmodding a series 4 penryn (1066mhz) and/or have gotten a series 4 penryn to work in a Santa Rosa/PM965 chipset? I know there have been topics discussing this, but all I got out of them is that some people says it works, while others say it doesn't.

I ask this because I'm going to be starting a project soon involving this issue.

 

I'd say the best way to get a 1066FSB CPU to work in PM965 is to Pin Mod the PLL to 200Mhz ( Force the CPU to 800Mhz FSB ).

Good luck, let us know how it goes.

 

Yeah, I read the OP, specifically the topic regarding the BSEL. Although my first course of action would be to edit the BIOS microcodes, I don't really know how to proceed. I don't know that the L-H-L and L-L-L stuff translates to which pins to connect.

Also (slightly off-topic), but anyone know how to extract an Alienware BIOS?

 

Can you give a link to your BIOS?

 

It's an CD image (.ISO). The problem I'm having is that the actual ROM is hidden somewhere in the ISO and I can't view the files. It might be in the boot image, but I'm a newb when it comes to that. You might have better luck with it. Here's the link:

http://go.notebookreview.com/?id=525X832&url=http%3A%2F%2Fsupport.alienware.com%2FSupport_Pages%2FRestricted_Downloads%2FMobile%2Fm17x%2FBios%2Fm17x_306_bios.iso

 

Looks like there is a floppy disk image inside the ISO file (along with other junk). I don't know how to extract a floppy image. You might have to burn the image onto a floppy to see the files.
I can probably try it when I find my USB FDD.

Use 7-zip to extract the files from the ISO as if it was a zip file.
Then burn the floppy image to a floppy disk.

 

Ok, I've done all of the extraction.

I have attached screenshot of the files in there.

As you can see it's in the form of a .com file not a .rom.

So you will have to find another way to get the BIOS file.
You could try using some software to get a backup (by reading straight from the EEPROM). That will give you a rom file. But you cant flash that file because it would be missing some parts.

Basically I don't think you can mod your BIOS.

 

What a sec. I see F17306.BIN (1MB) which would be your BIOS file that you'd want to try to modify to have the series-4 Penryn cpu (P8xxx) microcode. AFLASH2.exe is used to presumably flash the bios.

 

Ok, I take my words back, and here I attached the file.

 

It's an AMIBIOS. Try using mmtool to replace the CPU microcode module.

 

Awesome. Thanks moral hazard. The reason why I needed to do this is so that I can reflash the BIOS. The M17x's BIOS is write-protected unless one uses the program provided by Alienware to boot up and reflash the BIOS via CD. So, I needed to edit the ROM and put it back in the disk/boot image.

I used MMtool to swap the CPU microcode module with that of an MSI GT725 BIOS (version 1.0U), which has support for the series 4 CPUs including a QX9300 as well as some older CPUs. But is there a way to combine old microcodes and new microcodes into one module?

For now though, I'm going to try a P8400. I also ordered a T7100 to see if it would boot up with both the project notebook and an MSI 1722 (pretty much a neutered down GT725).

So there you have it. My project is getting a PM965 based system (generation 1 Alienware M17x barebone) to run with a series 4 CPU. I believe this can work because they said the same thing about the P965 (desktop) chipset not supporting the Wolfdale and the Yorkfield CPUs with their 1333mhz FSB.

BTW: parts are not here yet, should be here later on this week so I'll definitely keep you guys updated on this.

 

Don't know. You might have to visit one of the BIOS mod forums.

 

As I understand it, Intel CPU MicroCode Updates are for Errata ( Bug Fixes of the MicroCode ).

Microcode is not the CPU Detection code in the Bios, that's hardcoded in another place in the Bios.

So, you can't add support for a New CPU to your Bios, via a MicroCode Update.

I may look into CPUID Bios updating at a later time, so if your System won't boot with your new CPU Installed, post back and I'll see if I can look at it.

You may find your Bios supports your new CPU's CPUID already, but you'll still need to PIN MOD your PLL for 800Mhz as I don't think your RAM is Going to POST @ 1066mhz speeds.

 

Darth_nVader,

how to do this?

since my PLL is not in the setfsb list yet .

Thanks!

 

Select a similar PLL in setfsb.

 

I tried, there's only 2 Silego PLLs that are similar, and none of them (and other PLLs) works. Thanks!

PLL diagnosis also doesn't work

 

Try using "PLL diagnostics" as the PLL.

 

it doesn't work also

 

This is what abo replied to me

So I guess I'm outof luck even with PLL mod ??

 

No you can still do the second type of PLL mod.


The FSa/b/c pin mod.

 

I even harder to understand that one

 

First you should flash your ram to 533mhz (so that it will be stable when you OC the FSB).

Then you would have to GND pin 45 (after disconnecting it from Vdd).

See page 1 on this thread for more detail (thanks to nando4).

You would only have to flash one stick of ram with thaiphoon burner (the other stick would run at the slower speed automatically).

I would first check if there is a track coming from pin45.
Hopefully the track leads to a resistor. That would make it easy to disconnect pin45 from Vdd (just remove the resistor).

And then find a GND point and connect pin45 to it (using the resistor you removed or any 10K resistor).

 

and the cpu's fsb will automatically become 266Mhz??
(assuming all goes well)

I need to re-think about it if it's H/W permanent mod .. (or almost permanent)

Thanks for the hints moral!

 

Yes, it's as easy as that.

I guess you could wait a while until you feel that your T9300 isn't enough.

Also with this mod you might also have to volt mod the CPU to make sure it's stable. Because at 3.3ghz I don't think it will manage with only 1.2V.

So that means you would have to flash your ram, pin mod the CPU and then pin mod the PLL. A lot of work IMO. Might be worth it, I'm not sure.

 

Hi guys,

I have an acer 6920G and tried setfsb with ICS9LPRS365BGLF. It returned with this result attached. I need to confirm whether if TME is unlocked and which method should I use. Help appreciated alot.

 

Yes in your case TME is disabled (unlocked).

What happens when you increase the FSB?

 

Err nothing happens it just reverts back to default clocks. So should i be doing method 1?

 

hmm, I might have to look at the datasheet for your PLL.

I have to sleep now, I'll try to help in 10hrs.

You can download the datasheet yourself and check which bit is the TME bit.

 

Here is a link to your datasheet:
www.idt.com/products/getDoc.cfm?docID=18703881

You don't need to do the TME pin mod because you already have it unlocked. TME is already disabled. Bit 6 of byte 9 = 0.

You need to play with setfsb to make it work. Email abo and give him a link to your datasheet. Also try using a similar PLL in setfsb (e.g. ICS9LPR501SGLF).

You don't need a pin mod, you just need to troubleshoot setfsb.

 

Well based on here, seems that it will not work.
http://forum.notebookreview.com/showthread.php?t=331249

It puzzles me now that the readback says that TME is disabled but moving the slider doesn't do anything. BTW, I've tried other pll's as well and nothing works.

Tried method 0 on the cpu socket, lappie just shuts off by itself. Seems like I hit a dead end on this one. Any ideas left?

 

You should try method 2: Hardwired PLL for higher FSB.

But before you do, flash one of your ram sticks with thaiphoon burner to a slower frequency (533mhz).

 

Erm will it work? Isn't it similar to cpu pinmod?
I have ddr2 800mhz rams do I still need to flash them?

 

Yes it will work.

If you have the PM965 chipset then your 800mhz ram downclocks to 667mhz.
Then if you do the pin mod, your ram will overclock from 667mhz to ~880mhz. With the 667mhz timings.

If you think your ram can handle 880mhz with 667mhz timings then you don't need to flash. But my ram can only take about 850mhz with 667mhz timings. So if I do the pin mod my ram will not be stable.

If you do the pin mod without flashing your ram, it might not be stable so you would have to remove the pin mod then flash and do the mod again.

It's up to you.

You have a better chance of it working the first time if you flash one of your sticks of ram to 533mhz or at least increase the CAS latency.

 

Ok thanks alot!
Btw, by pin mod u mean method 2 right? Because method 0(pin mod) doesn't work for me. Or could it be my rams that are causing method 0 not to work(lappie shuts itself off).

 

Yes I mean method 2.

I don't know what is wrong with method 0 and why it didn't work. Maybe the ram is not stable or maybe the wire was shorting something out.

Good luck. Take your time with method 2, it's hard to solder something so small.

 

Ok so for method 2, I just have to disconnect pin 57 and ground it on pin 58?
In other words, I can just bend the pins together to make contact? and insulate the bottom of pin 57?

I read from this thread http://forum.notebookreview.com/showthread.php?t=390696 that you have to cut the connection to MCH as well?

 

You do not have to cut the connection to the MCH. That is BS.


You are right about disconnecting pin 57 and then connecting it to 58.
But make sure your chip is the 64-TSSOP (rectangle).

If you have the 64-pin MLF (square) PLL then the pinout is different so check page 6 of the datasheet.

I would not bend pins though. That could be trouble.

I would look at the track coming off pin 57 (if there is a track), if the track leads to a resistor then you would have to remove the resistor. Then use that removed resistor to connect pin 57 to GND (or use a 10K resistor).

Make sure you have a DMM to test the connection and to test for GND points.

 

Does setfsb's author, abo, say in his latest message mean he's no longer developing setfsb?


src: setfsb homepage

 

That's bad news. But I guess with the new Grub2 OC, setfsb is not really needed.

Too bad though, why stop at a million?

 

Moral hazard,
My notebook PLL is RTM875T-606, so I decide to crack it and OC cpu, like Darth nVader's thread, I ground PIN4 and the TME is disable, but when use setfsb, the system crash and reboot.
My notebook chipset is GS45 and cpu is SU9400(Penryn);
1) Run SetFSB->Click Diagnosis->Chose RTM875t-587->Click GetFSB; (setfsb detect error fsb to 166Mhz, but 200Mhz is running

2) Click 00h change bit 2 to 1->Hit Update->Hit Apply
Set FSB from 166Mhz to 266Mhz, the system crash and reboot, and then the fsb change to 266Mhz:

Please help me, why system crash and reboot for?

 

It's hard to fix without a datasheet.

Here is what I would do:
1. open setfsb, select the PLL, click on the diagnosis tab, click getfsb, move the top slider a little to the right and then press setfsb.

2. Just before the system crashes, take a photo with a camera of the registers.

3. Restart the notebook, manually change each bit in setfsb to make it look like the photo. When you get to the "bad" bit your system will crash again.
Then you will know which bit not to change.

4. Restart the notebook, manually change each bit in setfsb to make it look like the photo. But this time don't change the "bad" bit.

Hopefully you system will not crash.

 

Thanks hazard, I'll try it.
And did you konw how can I put the setfsb in command when windows start and set 00h change bit 2 to 1 automatically?

 

Sorry I don't. Though it is a usefull thing.

What you could try is grub2 OC and then you could do it. PM nando4, he will help.

I can give you a link to his thread if you want.

 

OK，please give me his thread, and thanks again.

can anybody help me with intel pm965 mainboard and proccessor T8100
i want to overclock the t8100 but i don not know the PLL that is suitable with PM965.

 

Your motherboard could have any PLL, it doesn't depend on the chipset.

Here is how to find it:
http://forum.notebookreview.com/showthread.php?t=429383

The T8100 could get to 3ghz (if you have stable ram). I run mine at 2.7ghz.

 

i have found this data sheet for PM965 mainboard:
http://www.intel.com/Assets/PDF/datasheet/316273.pdf

and where can i found the PLL?i looked in it but with no results....help.........
