I was building a new system from scratch and when I put my 2 gigs (2 sticks) of Crucial RAM in, the computer wouldn't boot. (one stick was in DIMM1 and the other in DIMM2) 
I then took out the second stick (so now just one stick is in DIMM1) and everything booted fine
But I really want to put my 2nd memory stick in so I put that in DIMM3 and nothing booted!
What's the reason here? Should I try one in DIMM1 and the other in DIMM4?
My mobo manual tells me NOTHING about this
This is what I have
Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory
on a
Foxconn A690GM2MA-8KRS2H AM2 AMD 690G Micro ATX AMD Motherboard - Retail
Thanks
