G skill memory question

[anubis2k7]

Recently built a new rig with an i5, p8p67 MB, and gskill ripjaws 8 gb 1600mhz memory (2 4gb sticks)

the system has stability issues (freezes on prime95 burning, and fails mem tests) but when I enable XMP, it seems to work fine.

I tried some corsar vengeance (same specs) and it worked just fine.

Why do i need to overclock the gskills? (XMP) will this effect my ability to overclock the cpu? is this bad for the board?

Thanks.

Overclock? Why would you overclock them??

You should run them at the rated speed. Can't really help you cause you failed to mention what model of ram you have, and what settings your having issues with.
