No Dual Channel

[alkimst]

This is a good one. ASUS M4A88T-M/USB3, 965BE W/Hyper TX-3 cooler, MSI HAWK HD6870, OCZ 650 PSU, 2X 2GB GSkill 1866 @ auto-detect 1600. Will not run in dual channel mode. First got crashes. Now It will not boot with the RAM in the blue or black slots. Any MEM OK light stays on. Pushing the button does not work. System is stable with one stick in the first black slot and the other in the first blue slot. This is single channel mode. RAM passed Windows mem diag extended test.

Is the ram on the approved vendor's list for the mobo?

Have another set (or a friend with some) that you can test with? Are you running the latest BIOS?

No, but IMHO these days it really doesn't matter. RAM is RAM and there's just no way a motherboard maker can test every RAM module made by every supplier. Besides that, the system was built in late 2010 and just started acting up.

Swapped ram, cpu, psu. Latest BIOS, even went back to original BIOS. NO GO.

Download Memtest86+ and run it for several hours one stick at a time. One of your sticks may have gone bad.

Another option is that the ram slot on the MB went bad. Any way to test your RAM in Dual-channel in a friend's computer?
