P_Doughboy's 7800gt voltmod

post #1 of 22
Thread Starter 
So i decided to try my doughy little hand at something new...voltmodding! so ckp64 let me see some pics of his 7800gt voltmod in the past and i modeled it exactly off of that and wala, it worked !!! before you look at this mod, i would like to give thanks to the user ckp64 for helping me along this mod...i rep you dearly =) pics below

a nice top view of the entire setup


the vgpu portion of the mod



the vmem portion of the mod



a nicely taken side view pic



here is what i used to test my voltages for vmem and vgpu so i didnt have to reach back and find those tiny little holes every time!



my mom was mad about the kitchen counter...



vgpu voltage (im gonna up-it more soon) deafault = 1.43 mine = 1.5 (for now)



vmem voltages (also gonna up it a little more) default = 2.08 mine = 2.21



and here is what happens when the doughboy drinks crappy Tab energy drinks


i havent started overclocking yet...will in a while and ill post the results on this thread...thank you for reading this

Nice.

I'm tempted to do the same to my 7600GT, but I fail at soldering, so I'll wait 'til I get more practice.

BTW --
My 7600GT gets higher clocks on the memory at 2.185v then it does at anything higher. Make sure your vRAM is "OK" with that voltage, or you'll OC will actually worsen instead of improving.
2 OP pls nerf
