-Philby: What are you talking about (in regards to volt mod on the BIOS-there is no such animal) You are just changing the default core & memory clocks in the BIOS. That's all you need to do (if he needs to do that at all considering his level of knowledge right now)
Not trying to be harsh, I've just seen more thn a few people come back screaming "my screen is blank, what do I do!"
Quote from Peter pan -
"Bios Flashing 7800 and OC to 500/1000Mhz
Its your own risk... and follow the instruction to backup your Bios first.
Nvflash 5.13 ( only this version works)
NibiTor 2.17 Bios Modding Software
Templogger for Nividia Card
1.) Make a backup of your Bios
a.) download nvflash and put it to the root c:\\
b.) Boot from cd and go to DOS prompt
b.) c:\ vflash -b backup.rom
2.) Change the Voltage
a.) open Nibitor load your Bios file
b.) change the Voltage to 1,3 volt in the 3D Mod - see picture
b.) save the file as you want --> oc.rom
Before you flash the bios --- PLEASE MAKE an Emergency Flash Disk -- Like this http://www.mvktech.net/content/view/415/37/
1.) Edit the autoexec.bat
2.) put this command in it --> nfvflash backup.rom
3.) Change Boot parameter in the bios CD-->IDE
Flash your modded Bios
1.) boot from CD
2.) Dos prompt
3.) c:\ vflash yourmoddedbios.rom
And now install tempLogger and check your temperatur of your card.. It runs with the orig Core of 250/658.
Now it ist possible to change the Core to 450/900 or something more. To overclock use Coolbits or RivaTuner.
Please post your results.."
- Basicly the current limit with the stock voltage is around 360/900 - however running this volt mod in the bios will aloow you to o/c further. From what other people are reporting it looks like you can increase the core voltage up around the V1.2 from the current V1.0 - not that I've tried as I just use rivatuner or the Nvidia drivers to run a max of 360/900 - but I've thought about having a play I'm just not to keen on melting something down.
Also I belive if you run these higher voltages then you need the 130W power supply and 9 cell battery to allow the extra current to be pulled.
