ok where to start... bought this mobo (crosshair) on newegg read reviews havn't installed it. plan on learning more about over clocking before i really get deep into this project. there was a frequent review comment about the upgrade to bios of 0904 making it usable to the new quads but taking away 1066 recognition for memory. i plan on running an amd athlon x2 6400+ with Corsair(8) X2(4g:2X2gb ddr2) 800mhz 5-5-5-18 1.8v. the mobo says it has a standard of 800mgz and has a setable frequency in bios of ddr2:400, ddr2:533, ddr2:677,and ddr2,800. so i was just wondering why this is. memory standard of 800 can u over clock to 1066? can u go higher? is standard memory a minimal? just looking for a little q and a please and thanks everyone!
