Need memory recommendations for Asus P7P55D... current memory seems unstable


Dec 1, 2000
I get occassional crashes to a blank screen (less of these after switching from 8GB to 4GB).

I get other errors such as superfetch stopped working, windows update stopped working, host process stopped working, microsoft software protection service stopped working, etc. It seems Windows 7 gets corrupted and I keep having to reinstall every few days.

This is the RAM I have now: G.Skill DDR3 1333 Ripjaws CL7.

I have tried it at auto settings (CL9), and with XMP (CL7 and voltage fixed at 1.5v).

Any recommendations? If I can't find settings that fix it, I want to try a different brand of RAM. Thanks for any help.
