Bad DIMM on Formula VII

[HappyBuddhaman]

I keep getting an error 55 on my Formula VII MB. I've tested all the DIMM slots with multiple single sticks of known good memory, slot A1 and B1 give me the 55 error. I've checked the cpu mount for bent pins, ran the mem ok button multiple times, made sure the cpu cooling block was secure but not too tight, just about done everything I could think of. It's still under waranty, before I send it out for an RMA, anyone have any other ideas I might of overlooked?

Hello HappyBuddhaman

Normally that's a sign of a couple bent cpu socket pins. When you checked the cpu socket did you use a magnifying glass in good light?

Did this problem just start or have you always got code 55?

Have you tried clearing the cmos or resetting the bios to defaults?

[HappyBuddhaman]

Started when I had to change cpu coolers. And I have cleared the cmos and reset and updated the bios. Had good lighting while checking pins, did not have a magnifying glass.

EDIT - just checked all the pins with a very bright LED flashlight and magnifier, they're all good. Had to switch the video pci slot, and two of my drives needed to change sata ports, as they were not being recognized, probably best to RMA the board at this point.

Well I don't like to tell anyone to RMA their motherboard as that is the last resort but seeing how you had to put your gpu in the second pcie slot and some sata ports aren't working along with DIMM slots A1-B1, it sounds like the thing to do.
