Hi my ststem is running games really slow, 5FPS even at the lowest settings(800x600). My specs E8500, 2Gb Geil DDR2 533Mhz, P5N32-E SLI, EN9600GT, think my performance issues might be something to do with my memory(2 1Gb Geil DDR2 PC4300 533Mhz) and the way it is set up in the bios(1405). Can u tell me if this memory is 100% compatible with my board(Asus P5N32-E SLI). And how i set the correct timings in the bios. CPU-Z reports that the DRAM frequency is 266.7Mhz. Should this not read 533Mhz because thats what the memory is rated at?
