Asus p4s8x-x - add 3.2 P4 cpu support

[KvackEvolution]

Hi!

I have an ASUS P4S8X-X socket 478 motherboard that have an Pentium 4 3.2 Ghz with the newest 1005.001 beta bios dated 2003/12/02 (https://www.asus.com/supportonly/P4S8X-X/HelpDesk_BIOS/). Now the problem is that the motherboard dont have official support for the cpu (Only up to 3.06 GHZ Pentium 4) but it clocks down the cpu to 2.13 ghz. And POST says invaild CPUID but it still continues to boot and Windows works normaly. But if i try to open an monitor program that captures info from the cpu the PC halts and restart. 

Now i want to upgrade the cpucode in the bios so it supports the 3.2 GHZ Pentium 4. I have the cpucode for it, but its easier said than done to edit the bios.
The file you get when downloading bios update is an 001 file which if you extract, you will get an SYSTEM.ROM file. I have tried open those files with Phoenix BIOS Editor but it doesn't work.

Tell sSpec of your Pentium 4 3.2 Ghz.
Show a photo of screen with error: "POST says invaild CPUID".

The Sspec is SL6WG.

Seems like the POST stopped complaining when i flashed bios to the 1005, but says is a 2133mhz Pentium 4. Sorry for being unclear in the first place.

I can't see this picture.
This motherboard is based on SiS648 chipset. It support FSB=533 Mhz maximum.
It's the reason for downclocking of your CPU with FSB=800 Mhz.

Ah ok.

But what can the problem be then with that it freezes soon as you open a monitor program ? The ones i tested was HWInfo, CPUID, Afterburner and HWmonitor.

EDIT:
Btw i found a Pentium 4 @ 2 Ghz - SL6GQ which i inserted instead.

But the problem still resists.

What's the operating system?

[KvackEvolution]

Its Windows XP Home Edition. But CPU-Z and Hwmonitor works now So i think its just HWInfo

OK.
Try to find Pentium 4 3.06 GHz with sSpec: SL6JJ, SL6K7, SL6NN, SL6PG, SL6QC, SL6S5, SL6SM.
It's the best CPU for your motherboard.
