What voltages are you running at?
I can't get my samsung pc2700 to run the 4:5 divider even at 160fsb. (It's the real stuff from newegg.com, as it says samsung on the PCB.)
Update for my temps. I'm now running 38-40C idle, and 47-52C under a full load with just 2 panaflos providing case ventilation, and a YS-tech variable speed fan on the Alpha. I like the Qfan technology, I noticed it does lower the speed of the fan when idleing. I don't even need the YStech running at full speed to keep the temps at a decent range. I found that 2500rpm only causes the temps to raise 2C or so from 3900rpm. At 2500rpm, the fan noise drops below that of the hard drives spinning.
This replacement board however, isn't quite as stable as the first one I had. I had to bump the core voltage up to 1.675 V to be able to run prime95 stable for more than an hour or so. Before, I had it as low as 1.6 V and it was stable overnight with prime95 and 3dmark looping. Guess it's just a crap shoot when it comes to quality
Thanks to those who recommended this board. I couldn't be more pleased with it so far, and I don't mind that I paid a $20-$50 premium for it. You get what you pay for, IMHO.
