DDR RAM won't work!

can't get ram to work properly.

can't work with slots:
dimm 1 & dimm 3
dimm 2 & dimm 4
dimm 3 & dimm 4

works fine at stock but not when oc:
dimm 1 (one stick of ram)
dimm 1 & dimm 2 (2 sticks)
dimm 2 (one stick of ram)

it's soo weird. after removing the ihs it wont' seem to work. but i'm sure that i didn't damage anything on the chip or scratch any of the capacitors because if i did why would it work with "dimm 1 & dimm 2 (2 sticks)". i think something is up with my dfi motherboard. but i'm not sure what is wrong. doesn't any one have similar issues? let me know.

thigns i have done:
clear cmos.
long cmos clear (8 Hr)




note: the ram ran stable ibefore

need some help please/

Are you sure your ram isn't screwed up? Try some other ram. Then if that don't work its probably your motherboard.

Check your motherboard for any physical damage. You can also try contacting DFI technical support.
