is there any way to add more voltage? - Page 2

post #11 of 13
You will be able to determine that for yourself based on temperature. Even though you have a great air cooler you won't want to run 1.2v on it for daily use, as you will see for yourself based on temps. Just make sure that once you get all this extra voltage headroom to play with that you don't just instantly max it out, still continue increasing voltages 12mV at a time and retesting to get an idea of temperatures. So with that warning and recommendation of caution, I think that based on your current temps you should be able to run 1.16v or 1.17v, possibly even higher. Your card is specified to have a max temp of 105C by Nvidia but with your cooling I would want to go no higher than 90C on the core, this is because your core cooling is much better than your VRM cooling so while your core may still have a little more room to go higher (normally I would say 95C is the stopping point on the core for a 480) the voltages required to get your core to a temperature that high would be torture for your VRMs.

Just be patient and make small gradual increases and post back with what kinda of volts, speeds, and temps you are seeing.

Personally I wouldn't go over the set limit (1.138) for 24/7 use on air but for the occasional bench run as long as temps aren't crazy (not over 95C) you probably can get away w/running around 1.2V. The thing I'd be worried about if you were gonna run 1.2V all the time is the temp of your power section (i.e. vrm's or mosfets), which there's no temp gauge for on the 480 ttbomk so you'll not know how hot it's actually getting/running all the time.

Also don't forget that anything less than about +15% fps is not really visible to the naked eye so pouring on volts just to eek out an extra 1-3% fps for gaming is really a silly and unnecessary risk IMO ...

I second this, I bought one for my 480 and some Shin-Etsu not long ago and it keeps my card nice and cool.
