P5Q-D is nice, I hit 590 FSB with no problems, could bench 3D at 572+ FSB and I found it to be a very stable board. I also have TeamGroup ram and it ran without any problems for me and although I had some ram related issues and RMA'd the mobo, I clocked it up to 1333 MHz. Sounds like you need to tweak some settings, your ram isn't playing nice with it, or your board may be defective.

DFI P45 Plus looks good too.
