Hello G.skill tech. I recently got a pair of these off newegg and am having problems. I am using an evga 780i with the newest bios, and they are in the correct slots. I cannot get the ram to run at stock speeds without errors in memtest. If i downclock them to about 900 -950 I can get them stable. Do I have a bad pair? It auto-detects volt at 2.1, I have even tried differ volts as well but still cannot get stable.
