Overclocking GTX 280

[George]

Hello,

1st off im new here and RRR sent me an e-mail and it looks like its going to be a great forum ;)

Anyway..

I have a W/C GTX 280 and i have it overclocked but lately it has been "sort of" crashing and the clocks on the Core, Shader and Memory plummet and go to way way below stock (im talking 400Mhz core, 200Mhz shader and 200Mhz Memory) and will only revert back to there normal or OC'ed state when i restart. The temps are fine mid 30's idle and mid 50's under full load so what i was thinking was that the voltages need to be upped. In Nvidia control panel i saw this....

*Note: I use EVGA precision to OC and the clocks have been lowered slightly to that on my sig for stability :D


which made me think (now here's the question :p) is it possible to up the voltages without a physical volt mod?

Not that I know. The only ways to raise voltage is either via a physical mod (great to put a voltage pot to adjust) or by flashing the video card bios with a new set voltage.

I like the sound of the second one :p

soo.....

care to explain a bit more :D?

Could you use something like Rivatuner to up the voltages ????

No, the voltage is locked in the bios.

I know there are guides and infos on the net about this but I never tried it myself.

Flashing it is the only reasonable option then, I'm sure theres a guide somewhere................
