So I've built this new system, and recently I've been getting some memory issues (6GB (3x2gb) ddr3 1600mhz). There are 6 total slots on the motherboard for memory. Using the first set of 3 (for triple channel), I got some results. Using the other 3 slots, the computer didn't boot at all. Not even POST. I ran memtest86 and this is what I've got: Individual sticks in each slot: all pass Every combo of 2 sticks: failed at 45% of first test all 3: test freezes at 7% of first test I've never used memtest before today so I'm not quite sure what these results mean. Is it faulty memory or possibly a motherboard problem? Motherboard: EVGA X58 SLI LE Let me know if any other information is needed. P.S. Also, for some reason, a few seconds after shutting down my computer (while I was changing and testing the memory), I hear a slight sizzling sound coming from somewhere on the board, though I can't tell where. Normal or could this have something to do with my memory problem? Thanks!
