I got random bluescreens whenever I plug ram in my mobo first slot.
Tested both sticks individually and paired in other build: both ok.
Actually I'm working with 4gb installed on second slot only, the other stick doesn't work in this slot. No errors 24/7.
On first slot no matter, none of the memories work individually. Both give me BS.
I Had a LC6600 psu that has been replaced (overvoltage).
