well, for the past 2 days i have had 512mb ram on my computer, but today i decided to put 1gb back in, so i got the other 512mb of ram, and put it in so it was in dual channel configuration, next thing i knew, is the computer wouldent boot, or post, and no monitor would come on, so i tried dual channel in the other 2 slots, and still no luck, so i decided to try just another 512mb stock, and wahey, i posted, i put both stick of ram back in, but not in dual channel, and it posted, so it seems i cant get dual channel to work anymore:(
no, as long as your motherboard supports say ddr 400 memory, and has dual channel on the mobo, it will work.
anyway, i got it to work again, i dont know what went wrong.
here is the ram slots
II XX , obviously for dual channel, i would have to etiher have both sticks in XX or II, instead of putting 1 stick in the left I, i put the stick in the right I, then started it up in single channel, then i put the other stick in the left I, and it started up.
before i also noticed my ram timing were somthing like 2.5, 4, 2, 2 after loading optimized defaults.
