Thread: 7800GTX Volt mod




  1. #1

    Default 7800GTX Volt mod

    Does anyone know where I can find a GOOD how to with the hardware volt mod on a 7800GTX? I have this one... http://www.tekbunker.com/articles/VoltMod7800Pt2/
    but the pictures are a bit fuzzy and it does not say which pins to solder.
    All software mods, even BIOS flashes have proven to not increase voltage..so I went and got the two POTS I needed for a hard mod. This is the first I've done and would rather not screw it up! I'll keep searching and update if needed.

    Any info will be appreciated!

    Ok...after a few hours of digging I found this...looks like I'm in for some ~600+ MHz clocks...or a dead card!

    All went well, the pictures are somewhat misleading, the soldering was much smaller than I thought, I actually had to use a magnifying glass and that's with my 20/15 vision. But I am satisfied with my results so far. I'm stable at 605@1.68 Vcore. Tems are under 50C and get a solid 10k in 3d05...

    I know I can go further, I was stable @635 but that was with 1.8 volts, a little to high from the other 24/7 overclocks I've seen.
