8800GT bios for better overclocking! *test*

[r4st4m4n]

FYI, I've used NiBTor voltage editor to pump up the voltage to 1.4v.
Flashed the card, and done some benching at 786/1890/1060

Just to add it wasn't stable but allowed me to run 3Dmark06 artefacts free.

Can you explain how you do that ?

According to people who tried and measured the Vcore there was no change pass 1.1V and also according to the author of nibitor you cannot change the Vcore to more than 1.1V through his software

Nice copy/paste guys... It seems you are all well following the thread on MVKTech but don't really discuss it there but rather here. To make it clear to every one, every BIOS you can add/change the voltage table but it depends if the voltage circuitry can work and recognize the different VID levels. And yes all turns around the VID level not the label you put next to it in NiBiTor.

So if VID 00 would give 1.00V, and you would use NiBiTor to change the label of VID 00 from 1.00V to 1.20V that will make no change at all as the VID is still 00 and that is what the card looks at not the label next to it. On the GeForce 8800 GT, the VID 00 is 0.95V and highest VID 03 is 1.10V. So you can do what you want but none of the VID's 00 to 03 will give 1.20V. But maybe VID 04...if possible and if the card can work with it.

Yes, and it is not capped. The voltage circuitry on NVIDIA based graphics card only looks at the VID xx (the label 1.1V or 0.95V is just for you guys ti understand what each VID give sin terms of voltage). The card just looks at VID xx, and for the GeForce 8800 GT, the VID 00 is 0.95V, so having set the core at VID 00 the GPU voltage circuitry will recognize VID 00 and run at 0.95V. And VID 03 is just 1.1V... So if there would be a VID 04 then maybe we could get 1.15V...

And if you check in the 8800 GT vmod thread in the Xtreme GraphX Vmods subforum, there is an OVP on the 8800 GT that kicks in at 1.3V ...

Did you measure the Vcore with a DMM ?
