I'm getting these with my CPU @ 3600 with RAM @ 800 using 4-4-4-12: Stick #1 Stick #2 Stick #3 Stick #4 I used banks #0, #1, #2 and #3 respectively for testing the sticks #1, #2, #3 and #4, individually. The reason i did it this way is because i'm unable to boot with stick #2 in the board's bank #0 (blue slot). I was told to test the sticks again, without the OC on the CPU and with the sound card removed from the PC, and test all of the sticks in bank #0 so i proceeded as suggested. Stick #1 got zero errors this time but, when i tried to boot with stick #2, i couldn't I can boot with this stick in bank #1 just fine but, and i just tested this a few minutes ago, i can't boot from ANY of the blue slots (banks #0 and #2) with this kit, though i can with the other, and yet, it's the other that gives me errors in the MemTest (with the CPU OCed to 3600 MHz). I'm confused I've actually noticed this behavior before: i've sent this board to RMA because i couldn't boot in the blue slots though i could in the white ones (only had 1 RAM kit @ the time), but the tech dude @ the store tested it and it booted just fine I think the problem lies with the board, thought the RAM might be affected as well. Has anyone had something like this happen? If so, what was the cause?
