Guba Posted December 9, 2013 Share Posted December 9, 2013 Greetings, I recently decided to upgrade my RAM from 4gb to 8gb. My old setup was a matching kit of 2x2gb, produced by a competitor. I purchased an additional 2 2gb RAM sticks from another competitor, these however were not a pretested kit. When I installed the new sticks, however, I could only access a total of 6gb, with 2gb in reserve. After doing some research, I found out that the issue was most likely one of compatibility between the newest two sticks as well as between the two sets, as my mobo did not support a 4DIMM setup from these two producers. According to the Qualified Vendors - list, I found a single 8gb kit that SHOULD work on my mobo, at least according to Asus. So, I proceeded to purchase a Corsair 4x2GB, 1333MHz (CMX8GX3M4A1333C9) - kit. However, after I installed the new kit (all 4 sticks replacing the old ones), I could not longer get any signal to my monitor. I tried using different ports, even the mobo's GPU, but nothing. I switched the sticks around, nothing. I replaced all but 1 with the old sticks, still nothing. Only after replacing ALL of the new sticks could I get a signal. I'm guessing the problem is that the system does not boot properly with the new RAM, for some reason. Their frequency is the same as the old ones, so that shouldn't be a problem. Have you encountered this issue before? I'd really like to get these new ones to work, they were quite expensive, after all. My PC stats: OS: Windows 7 Home Premium 64-bit Mobo: Asus M4A89GTD-PRO CPU: AMD FX-6350 RAM: 3DIMM setup of 2GB sticks, from 2 different producers (no point in posting if they get censored anyway?) P.S. I recently updated my BIOS to AMI 3030, as it was necessary due to my CPU upgrade (AM3+ to be installed in an AM3 socket). Link to comment Share on other sites More sharing options...

Yellowbeard Posted December 10, 2013 Share Posted December 10, 2013 Clear your BIOS, reset it to system defaults, and try booting with a single Corsair module in the memory slot closest to the CPU. Link to comment Share on other sites More sharing options...
