*** Nvidia GTX 460 Overclocking Thread ***

[wyemarn]

I'm using EVGA GTX 460 1GB EE. The default VID is 1.00V and I edited the BIOS to run at 800/1600/2000 with NiBiTor.

A few days I go, I got a Sparkle GTX 460, purple fan version for SLI. The default VID is 0.9375V.
I tried to clock it to match EVGA's 800/1600/2000 but it couldn't finish 3D Mark 11 loop so I guess the low VID is the culprit.

Is 0.9375V too low to reach 800/1600/2000? Or the card I got is crappy with bad heatsink? Temperature is lower than my VGA though, and less noise.

Could be, you can always try 1.0v then you should be fine. Temps don't sound like the problem here.

I managed to edit my bios to increase voltage upto 1.212v and unlocked the fan speed upto 100%
Even at stock speeds, the VRM gets very toasty and I cant even put my finger there longer than a second, so I added some heatsink on the VRM using those Coolermaster mini heatsinks with some 3M thermal tape, the heatsinks becomes very hot as well during load so this means they are doing their job, still the back side is pretty toasty.

Would would 1.212v be safe for 24/7 usage ( gaming ) ?

Aside from Kombustor do you guys still use 3dmark for synthetic stability test ? What specific tests?

I would also like to know if 1.2v or just under would be good for 24/7 gaming? Especially if your under water? Personally from what I've seen on this forum is that it shouldn't be a problem
