So I was attempting to upgrade my 2x4b gskill ddr3 kit to a 2x8gb kingston ddr3 kit. I can't get to POST with the kingston ram in place. I get an error code C1 on my motherboard (z68x-ud7-b3) which is a RAM detection error. I double checked my bios is the latest one available and I've tried each stick individually in each slot with a bios reset in between to the same effect. Any ideas?
