8x00M Overclocking under Windows XP

Hi, recently became one of lucky IFL90 owners, and after some problems with installation finally came to tuning.
I read this forum a lot, and know this is not a first thread, but unfortunately there is no certain guide how to overclock under Windows XP.
On laptop2go forum someone mentioned that overclocking is blocked in BIOS, and driver reads that bit and forces to use only default clocks. So I suppose the solution would be:
1) Edit BIOS to enable overclocking.
2) Get a driver without the support of overclocking bit.
3) Get some hack to rip of anoint Nvidia’s nag from drivers.

1) Since Compal stores video BIOS with the main mother board BIOS and none utilities like NiBiToR can't read it, this variant is automatically off.
2) I personally tried 10 or more drivers (15x-16x) and none let me overclock, really disappointed (by Nvidia ). If somebody knows any, please post a link.
3) Didn't find one of those either, didn't anybody for 5 all month from 6mlrds wasn't able to hack overclocking protection off?

So please, help me find solution for this anoint problem. Need that OC like a drug. ^^
Thank you.

P.S. Don’t offer to install Vista and hope for the happy future, Vista is not ready yet. And as 8600 isn’t capable to give descent FPS in DX10 game there is no points at all, only incompatibility problems.

 

try last version ov rivatuner 2.05
maybe oc lock fixed

 

Nope, was OCing with it from the very start? Monitoring clocks doesn't even move a bit. Nor with RivaTuner, nor with ATITool.

P.S. I flashed BIOS to version 1.12.

 

Woohoo, I found some!
The thing is that if you install the driver with OCblock you have to uninstall it in the certain sequence. Here is the minimum what to do:
1) Remove driver through Add/Remove programs.
2) Restart you laptop.
3) Install new driver through device manager have disc function only! Confirm change if it askes.

So here some drivers I found to be overclockable (the latest from each series):
10x.xx - 101.29
I seen some gays on futuremark overclocked with 101.34 drivers, that come with MacbookPro laptops, but unfortunately I didn’t find them with the support of 8600M GT. If anybody has it, please give a share, thanks
156.xx - don't allow to overclock at all.
158.xx - don't allow to overclock at all.
163.xx - 163.44 allows only 2D mode.
167.xx - 167.26, shader domain clock indapendent OC is also available!
169.0x - Same as 167.26.

Here is my scores:
3DMark05 9233 @ 670/1470/519 WR
3DMark06 4639 @ 680/1475/519 WR
Steel need to do some experimenting with GPU, new drivers sort of made its’ OC potential go higher.

 

interesting find Dirt. I guess the result vary on everyone but I'll give have disk function a try later, it's close bed time for me
Keep us updated what you did~~

BTW, what tool you used to overclock?

 

I used RivaTuner 2.05 for making overclocking profiles and ATITool for finding artifacts.

 

101.28 driver was stock with my dell vostro 1500's 8400M GS. Once I wiped that out with driver cleaner properly, I upgraded to 158.22 using have disk method, and overclocking is no longer possible. Many other people have had this problem, so it seems like only the 101xx drivers are overclockable in XP at this point...
I've also heard that if u try to go back to stock drivers, you still cant overclock...anyone try?

 

Yop, as for me I also found only 101.xx (xx<=29) to be overclockable. Maybe there are some other drivers, but they must be different from laptop2go, since I tried all of those, even every single beta.
That's pretty bad, since 101 are too old and have awful CS:Source deep fog bug.

 

YES, a breakthrough! New 167.26 drivers support overclocking once again, first after 101.29, now I can OC and play CS:Source without foggy bug at the same time. ^^
And the shader domain OC option is also active working! This must be the best gift from Nvidia ever.
