GTX 470 Overclocking - Page 5

post #41 of 46
Listen to CL3P20 here, he's bang on.

I agree with the part about cold, my 470 gained 57MHz onto its max clock for unigine heaven when I put my rad in a bucket of iced water. Temps make a massive difference with fermi.
Regarding memory OCs, I can run 1950MHz for benches below 800MHz but I couldn't run above 18501875MHz for cold heaven runs at high clocks or it would just crash.
Keep your memory clock at stock until you find your max core clock and then up the memory clock. The core is basically all that matters here anyway because it will make a much bigger difference than a memory OC will.

Edited to fix max clock in Heaven, I checked to make sure and I was wrong with 1850.

Just curious, why does everyone say "fermi"? Doesn't that mean refurbished? My card isn't refurb tongue.gif

The GTX 4** cards were codenamed fermi. It's their architecture, like intel's sandybridge or AMD's bulldozer.

Go to the 400 series wikipedia page to read about it. smile.gif

Just FYI, I found my max clocks on my 470 are 825 @ 1087mV, and I just keep mem clock at 1800. Past that games and my system freeze. While folding with advanced WUs I drop the OC since even with a Zalman 3000F cooler temps go over 100C at max clocks. Gaming at max clocks temps are ~60C max.

Basically; 830core is alright, really between 800-830 you aren't going to see much of an improvement for gaming, unless you care about every fraction of an FPS...

Yes, 11FPS from stock to 830, but 800 to 830 how much of a change?
