another thing. Is it just me or did my pc just went A little bit faster? I tried to benchmark my NBA 2k13 and Borderlands 2 games on highest settings(physx on) and the ave fps of both games went up in 2x4gb single channel config. about 40+ increase in NBA 2k13(60+ to 100+ fps) and abut 10-15 fps in Borderlands 2 (55+ to 65+ fps). Really really wierd considering. Also the boot up time was considerably less than when i was in dual channel mode.
