That's a gigabyte board, right? I got an older one, and it's great.. Did you do everything you needed too? Put a divider on the RAM, lower the HT multiplier, up the voltage alittle? If so, then too bad. I could OC my single core sandy (3700) past 2.8, but I got my x2 3800, and it was a dud. I can't overclock from the bios, it doesn't post, I have to set all the settings (mem divider/HT mult/voltage) in the BIOS, but leave the HTT alone, then use easytune within Windows to OC. There I can get to 2.8 easy.
