Stop grant cycles / MCH configuration register

[rgf]

Hello,

I would like to edit some values; however, I don't know what program to use. I succeeded in unlocking 99% of my hidden bios features, except for one.......Hyperthreading.... I used a utility called " tmods biosmodv3". Next, I ran Intel's Hyperthreading technology readiness tool and it reported that I didn't have hyperthreading because of the following:

1. The cpu wasn't being ID as an Intel 3.06 P4
2. The fequency didn't match
3. Stop grant cycles need to be set to logical processor count -1, in this case 1

Is there a way to edit the MCH Configuation register to change the logical processor count? I might be able to enable the hyperthreading option in the bios if I can change a register or two so that it will appear in the bios? I do have the latest bios update for my motherboard and it supports hyperthreading but only if it recognizes the cpu as being an Intel 3.06 processor. I also ran cpu-z program and it reported that I did have a hyperthreading cpu.

Just a thought...Is there a utility that I can run in dos or winxp that will let me change the cpu's ID? Don't slam me please, I've read alot of posts over on VR-Zone and HardForum on this subject and alot of good ideas were posted. I think this might be the route to take.



My system:
GA-8IHXP v2.1 w/ F8 bios
Intel 2.53 ghz cpu
1 gig 1066 RDRAM
Radeon 9700pro
Antec true550w
CTX monitor
5.1 Avance audio

this is OT, and (sort of) slamming you,
but plz post in 1 forum...

We've been over this... hyperthreading is disabled on non-HT chips, and you as an end user cannot enable it.

edit: just to clarify, from reading your post, I get the impression that you have a 533MHz P4, which is not HT-enabled. I apologize if I'm wrong.

Here we go again.

You cannot modify the CPUID. This is a hardware string in the processor.

You might be able to enable HT in the BIOS, but this is not enabling HT on the processor. HT is PHYSICALLY disabled on the processor.
