Volt Modding a 8800GT

post #1 of 11
Thread Starter 
Hey guys, ive recently overclocked my Zotac 8800GT *non Amp! edition* and ive managed to get 738/1728/1080 out of it so far. I was wondering, how would i go about volt modding it through NiBiTor? I want to try and push it as far as it will go. Im confused on how to get the current bios off my card, and what to do with it after.

Also, is it safe to volt mod using NiBiTor? I only want to do it a little. 1.1v is meant to be safe? I think im at 1.0v stock atm.

Thanks in advance!

You are either at 1.05 or 1.1v already (load is +.05v higher). 1.1v is the highest you can go with just a bios mod.

It's as simple as going into NibiTor, reading the BIOS from your card into it, changing the "Extra" voltage setting to the highest one available, saving the BIOS to a file, then using NVFlash to flash that BIOS.

The clocks you are getting now seem to suggest that you may already be at 1.1v, but it's worth a look.

The nibitor read bios error is a Vista (x64 only?) issue. You can boot into dos and use the newest version of nvflash to save the bios and then edit it in nibitor and then use nvflash to flash it back on.

NVFlash 5.57

Volt modding isn't worth the cash you have to shell out to ship it for RMA, if they accept it, or to buy a new card. If you're willing to replace it, then buy a second one and SLI them.

You can use nibitor to bios volt mod it.

Also if you would have gotten the xfx version of the card you would have a lifetime Service

Right, after copying my backup, setting the 'Extra' to 1.1v and flashing it back on, i cant get any higher that what i got before, i must already be on 1.1v.

Oh well, it was worth a bash. Thanks for the help all, +rep!

Make sure you have the latest NVFlash.exe. Put it on a floppy/usb stick. Boot to dos using bootable media. run nvflash.

nvflash.exe --save <filenamehere>.ROM

Boot back to windows open up nibitor make your changes, save the bios to a NEW file dont overwrite your original bios ( )...

Boot back into dos using your own bootable media. run nvflash again.

nvflash.exe <yournewbios>.rom

read the screen carefully before pressin "Y". After you press "Y" it will begin to flash. Dont touch anything... flashing will take about 5seconds. After that your done.
