I got a new motherboard and processor today: Intel 3570K and the ASRock Z77 extreme4. After setting it all up, the debug on the board displays error #55. Which says "Memory not installed." When take out the ram slots it says error #53 which is "No physical ram detected." I've tried swapping the ram out, and I've learned the ram works. I read that it could be the motherboard or proccesor. I'm curious about which it is so I don't have to send 2 things back for RMA. If you have an answer, that'd be grearly appreciated! Thanks for your time!
You need to update the BIOS to 2.1+ The BIOS it comes with does not support Ivy Bridge. To update you can either call ASRock and they can send you a new chipset with the updated BIOS or you can use a Sandy Bridge CPU to update the BIOS then once it's updated switch back to your new Ivy Bridge.
I'm in the same boat, currently waiting on a cheap Celeron Sandy Bridge to come in.
