I recently aquirered 2x512 sticks of ram to replace my current 2x256 setup. Both the new modules and the old ones are OCZ (Performance line I think, one step below their O/Cing line) with heatspreaders (they probably don't do anything, but they look cool and I can't remove them w/o voiding the warranty. I was intending on selling the 256s, but they wouldn't fetch me much (a freind will buy them for $40). So, I am thinking of using them in my system in addtiona to they new sticks. However, I have 2 questions:
1.) I have heard that there can be stability issues with multiple assorted stick of ram. Is this in any way true?
2.) Has anyone tried to put 4 sticks with heatspreaders onto a mobo that has the ddr sockets right nixt to each other? (like this
)? I am very concerned aboout any bending/forcing that might be needed to get the sticks in there.
3.)Are there any possible memory issues that will not be detected in memtest?
