i first done A1 B1 it's work fine . i got dual channel
then i done A2 B2 but got only 4GB total then i revert back to A1 B1 it's not working
now i install it on A1 A2 on single channel and i get all 8GB

what wrong with mobo ? according to manual it should be A2 B2 which is not working .

BIOS detect ram on both A2 and B2 slot but i get total 4GB ram in BIOS and windows showing 8GB ram with 3.97GB usable . :confused:

yes but after buying RAM :banghead: it's model is not showing there . but most of the time it work . i use many gigabyte mobo previously . this is my first asus mobo so maybe it's because ram compatibility issue . also ram which i m using is run @ 1600 @ 1.65v i m going to try my friends 1033 transcend RAM today

Mobo supports 1600mhz ram and i think cpu will do the same.

yes no problem with ram even my friends 1333 ram giving same issue . so it's mobo . some people says it's because cpu pin bent . but as i install new CPu and i cross check there is no pin bent it's mobo that won't making proper connection between cpu and ram . so i need to RMA asus momo . now tell me how to RMA mobo i leave in mumbai .
