Hey guys, I recently got a 7750 and was wondering how far I could OC it.

I have the stock heatsink(the no heatpipes version), so temperatures are no where near what they could be. Running p95 large ffts, I get 65C on the cpu, and the cores get to 45. Voltage adjustments on my board aren't very hospitable either, I have stock(1.35), 1.4, and 1.5.

What I need to know is what temperatures I should stay under while overclocking this thing.

Might as well add me to the club. Got mine to 3.16, but have hit a wall. I hope you guys can help me.
Just about everything is on auto except the ram uses 2.2v from the factory, fsb at 204 and multi at 15.5. CPU-Z shows fsb at 203.

mdcrt... you need to pump up some voltages there.

I have tried 1.4v. I am a little hesitant to go higher. What is the safe, max voltage?

mdcrt...well I have stable 3.2GHz with stock cooler and 1.45V. And only 30C at the moment
Memories running on 2.1V 1066MHz.

I was able to go even 3.3GHz... but then getting bluescreen on 3Dmark test. Thou Im going to try that again when I get a new Noctua cooler.

My 7750 seems to be running really hot and I don't know why. I had been running it at stock, and then 2 days ago it started crashing when under full load. When I went to investigate, first thing I noticed was that my voltages where all over the place, So I got a new power supply. Still, if I have my Vcore set at 1.275, it will jump from anywhere between 1.250 to 1.360, which seems bad. So I started looking on forums, and saw a post on here from a week ago where someone posted their stock temps and OC temps and voltages, and something looked wrong. When I leave everything in the BIOS to auto, and MB still feeds 1.4v into the Vcore, and my chip idles at 40c, and hits 65c and shutdowns under full load. Lowering the Vcore to 1.275 lowers my idle temps to about 37, but still hits 58c under load. Any lower Vcore and the box won't boot.

My only ideas are either the MB sucks and its A: feeding too much juice to my chips, or B: My CPU is bad and just puts off to much heat. Or maybe the temp sensors are bad? It says the exhaust temp is 44c, but it sure doesn't feel that hot...

At any rate, I really wanna get this thing overclocked, but seeing as it is barely stable at stock settings I don't know what to do. Any help would be awesome.

Thanks.
