ASRock Z77 Extreme4 MoBo won't boot with more than one stick of G.Skill Ripjaws X RAM installled
This is my first build and all is going well, except for the fact that I can't get the PC to boot with more that one stick of RAM installed. I have: ASRock Z77 Extreme4 4x8GB G.Skill Ripjaws X DDR3-1600 CL9-9-9 1.50V PC3-12800 Intel i7-3770 LGA1155
When I install any one of the four sticks of RAM into A1 or A2, then the machine boots to Windows just fine. When I install more than one, it starts to power on, presents a couple of numbers on Dr Debug, then stops at error code 55, which is Memory not installed, then powers down and retries. It will do this until I hold the power button to shut down. I have tried as follows: -Dual Channel (A1 and B1; A2 and B2, as prescribed by the MoBo manual) -single stick in B1 -single stick in B2 -All four sticks loaded Each of the above scenarios results in a failure to boot and a 55 error code in Dr. Debug. I have updated the BIOS to the latest from ASrock's web site (P2.80), which didn't help. Any ideas?
