Drewy Posted July 8, 2009 Share Posted July 8, 2009 Hi I am attempting to increase the ram on my PC. I have been running Dominator Twin2x4096-8500C5D. I purchased another set of ram the only difference being is the version number. the original ver 2.1 the new ver is 2.2 When I install the new ram I get main bios checksum error and the PC reboots and then continually loops with a message scanning bios image from hard drive. If I remove either pair of ram the PC works fine but when both pairs are installed (8gig) I get the checksum error. If I remove 1 ram chip ie 6 gig remaining the PC works I am unable to get to the bios as it remains in a loop. These sticks are in the Corsair compatabilty list. Any help please.
