This one is only stable at 2.7GHz, though, I can run benchmarks at 2.85GHz (not prime95 stable). The cpu itself is as mentioned above, an Athlon 64 3700+ 2.2GHz. I am using air cooling now, my old water-cooler won't fit this socket unfortunately. The air cooler is the stock heatsink from an Athlon X2 4800+ (the big one w/ heat pipes). I also put an 80mm Delta running at 7 volts on it. It is completely stable in prime95, linux compiles, mlucas prime tests (real sensitive), and everything else I've tried at 2.7GHz. The board is a DFI NF4 Ultra-D with the 6/23 bios. Multiplier settings are 300MHz bus (200 is default) and a 9.5x multiplier for testing at 2.85GHz, 9x multiplier for normal operation at 2.7GHz. CPU voltage is normally 1.40v and is is set to 1.55v at 2.7GHz, for 2.85GHz test runs I use 1.6v. As far as CPU temps go it is usually 27-30c idle and 41c with various chess engines. Prime95 gets the CPU up to 45c. I wish I had bought the 2.2GHz Opteron 939 pin. The new 939 Opterons have been doing extremely well, in the 2.8-3.1GHz range with air cooling. A friend of mine just got his in yesterday (also using a DFI Ultra-D) and has it doing stability tests at 2.8GHz and 1.50v. I presume he'll be able to get 2.9GHz stable as a maximum (probably around 1.6v) and 3GHz benchable. I'm willing to sell my current Athlon 64 CPU if anyone wants it :)
