This is my second set of Micron D9 GMH DDR2-1066 that got flaky even with below rated voltage settings for 24/7 use.

In my first set, one really died after over a month of running @ DDR2-1000 CL4.0-4-4-12 with only 2.2v and with active cooling..

The second set which I'm still able to use @ DDR2-667 used ran @ DDR2-1100 CL5.0-5-5-15 with only 2.0v for almost a month until yesterday... now one of the sticks is dying..

Is my motherboard killing my RAM or am I just so unlucky that the replacement for my first set is a dud as well?
