I can run the system fine with one stick of RAM in slot 1 or 2 (A1 or A2) but if there is a stick of RAM in slot 3 or 4 (B1 or B2) - either with or without the other stick inserted - I get a 4-beep timing error code, the fans and LEDs power on briefly, then the computer shuts down and tries re-starting again, only to go through the same pattern over and over til I cut the power.
I've played around with both RAM sticks and all 4 slots, checking that the RAM is properly seated, and I've concluded that slots 3 & 4 aren't currently working. This is a pain since dual channel will only work in slots 1 & 3 or 2 & 4, not 1 & 2. My thought is that either I need to change something in the BIOS or the mobo is faulty.
Updating the BIOS didn't help and neither did setting the timings manually to 9-9-9-24-2N (as listed for my RAM). Beyond that I am not familiar enough with the RAM BIOS settings to do much. I've logged the issue with Asrock support and I am waiting for them to respond.
In the meantime, does anyone here have any suggestions as to how I can fix this (assuming the mobo is not faulty)?
