I got my ASRock Z68 extreme3 gen3 motherboard in the mail, as well as everything else I'm building with, and I'm having some issues.
I get everything hooked up, ready to go, and I go to power on my system to make sure everything is working. It doesn't pass its POST, and beeps 4 times. Dr. Debug is giving me error 55.
After some reading, I've come to the conclusion that the motherboard isn't accepting the ram, and that I probably need to update my BIOS. Are there any other things that could cause this problem? Everything's compatible, installed the way it should be, etc.
I ran into this problem myself. If you think the RAM is still working then it's a bios issue. And yes, updating the bios fixed it.
This line shipped with a bios before the Ivy Bridge existed, and doesn't support it. Flashing a new bios isn't exactly possible unless you have a sandy bridge lying around, but if you call ASROCK they'll send you a chip with the new bios. If you bought the Mobo recently it will be free, otherwise it's $15. It's really easy to swap out the chip.
