I bought an Asrock Z77 extreme 4 for a new build and can't get it to POST. I bought two boards before this and tried to get them both to POST, but no luck. I had a Biostar Z77 first and then an Asus Z77, both had this problem.
So, I set it up normally and I get a Dr. Debug error 55 (Bad RAM). I have tried two kits of DDR3 and neither of them work. I tested both kits with memtest and they came up clean. I tested the power supply and that works fine.
Any input would be greatly appreciated. I have worked on this problem for about two weeks and just have no idea what could be doing this. The only thing I can think of is bent pins on the CPU (which I cannot see) or a BIOS that needs to be updated. But the BIOS should support Ivy Bridge at 2.10, according to the manual.

Asrock sent me a new BIOS chip and I installed that, and cleared the CMOS.
No difference. I am running out of ideas.
