I'm a little out of date when it comes to memory but my understanding is this should work and it isnt. Bought a brand new ASUS P5K-E motherboard with 2 sticks of Crucial PC2-6400 memory and if i put both sticks in DIMM1 and 2 (respectively) system POSTS and everything is fine but the POST states (and cpu-z confirms) that my RAM Is in single channel. which makes sense because i think 1 and 2 are both in the same bank. If i move one of them over to a different slot, the system wont POST. i dont get any error beeps (i dont know if i should with the P5K-E, i'm new to this motherboard), but i dont get video or keyboard lights or anything, just fans turning. If i put the two sticks of ram back in the original slots, everything is fine. It was my understanding (limited as it is) that putting one stick in one bank and one stick in the other bank would allow for me to do dual channel memory. the memory should support it and i bought it as a 2 gig kit (two 1gb sticks in a package).
Any ideas what i'm doing wrong here?
Here is a dump from CPU-Z of what i figure is the relevant stuff:
