I got a evga 7800gt and 2 gigs pc3200 dual channel ddr400. When I clock my cpu at 2.2 ghz with ram setting at (auto), i get 155 fps average on source with doing the video stress test, when i overclock to 2.7 ghz with ram speed at 110mhz its 150 fps, what would be the best settings toget the most fps out of my system, another thing, if i dual channel my ram, shouldnt i be getting 400mhz ram speed?
