32 or 64 bit OS? 4gb ram won't be recognised on a 32 bit OS! First thing is to reset CMOS and load defaults and don't overclock anything then try the RAM at stock settings and see if it's stable.

I have an ASUS Crosshair with 2gb (2 x 1gb), SLI Ram is enabled, CPUOC is 0% and SLI Profile is set as 'High Performance' for my Crucial Ballistix 800Mhz DDR2 with timings 4-4-4-12-2T.

I have also had problems with the machine not posting and have had to swap the RAM to the other 2 slots to get it booting, and the other day I had to swap the RAM back to the original 2 slots as it woudn't boot again? I've also had a stick go down and had to RMA it so maybe these ASUS boards aren't actually setting the correct voltages? Tried a BIOS update or manually setting the voltages/timings yourself?
