any of you guys using powerchip based 2gb dimms find the sticks overclocked better on either colour dual channel pair? white (a2/b2) or blue (a1/b1). i'm running a pair of gskill pi 1100s on the white slots now and couldn't for the life of me get them to pass memtest at 1200mhz! i'm going to try the blue pair later on tonight and see if I can manage it. Not sure whether its the sticks, the 266 strap the divider I want lies on, or the bios memory tables aren't all that great for powerchip ics.
