Any tips ?

1) If you haven't, download and install MSI Afterburner to OC.
-One other program I recommend is HWBOT as it can display your VRAM temps, but don't use HWBOT all the time as you can get a nasty hiccup every time it takes a reading. Apparently it's a known issue with HWBOT to cause hiccups.

Memory overclocking on these in a breeze, I usually set it to 1500-1550, bench on a program like Heaven or 3dMark and just make sure my VRAM temps are reasonable (less than 100C is OK, mine stay mid 70s @ 1500).

Now are you looking for maximum clocks or a happy voltage/temp middle ground?

A rule of thumb that most people use is not to go above 1.25V at max while on air. I personally like to stay away from volts that high to ensure a longer life for the card. Temps should also stay below 85C, I prefer lower around 70ish though.

Don't bother with the intensive GPU burn-in software (Furmark). It used to be a good tool to find artifacts on my 5850, but I was able to get unrealistically high clocks with no artifacts in Furmark, but then try to play Battlefield 3 and it would crash in a minute. My next point, after you have found an overclock that stays within good temps in Heaven/3DMark, then play the most demanding games you have. I have found no better stress tests for my GPU than Battlefield 3.

Another thing to note is while your GPU may run at a higher clock, you will have more heat and fan noise. My 7950 can do 1100mhz but I stick at lower volts and 1030mhz to keep fan noise down and temps around 71C. Good luck with your clocks!

Thanks a lot, good advice. I got another case fan to vent my case better and ill post clocks when I get home from work

So running 1.25 volt
1100 core
1500 mem

Every game runs fine except crysis 3 and only on single player. It crashes after 5min or so...

Any ideas?

I was 100% stable with 1100/1500 1,06v but then I tried Crysis 3 and I wasn't. Raising voltage by 20mV got me stable again.
