I cant understand , I have a GA-965P-DS4 v1 installed a recently bought 4GB DDR2 800 MHz Cosrair TWIN2X4096-6400C5DHX 2x2G (1.8v) but in the start up it says memory runs in single channel and it only sees 2GB of ram.. i've placed the 2 modules correctlyso that the dual channel should work but it doesnt. Cpu curently is core 2 duo E6300, the rams are 800mhz i dont see what the problem is , maybe a bios set up? Can someone help? Thanks (windows 7 pro 32 bit)
