Mb or ram?

post #1 of 4
Thread Starter 
Ok guys, i have had this problem with my ram for about 6 months where the ram won't run in dual channel memory mode at the full 4gb.

Instead it runs at 1.99gb in dual channel mode and 4gb in single channel mode.
I have tested each individual piece of ram and they run in dual channel mode at 2gb no problems.

My question is: do you think this is a ram issue or a motherboard issue?

BTW i have tried literally everything to fix this. It's not windows, and yes, i have run memtest with no problems.
There is no option for memory remapping on my computer, and the ram is running at the right voltages.

If there were no problems in memtest then it sounds like an issue with the motherboard.

Are they both in the dual channel slots? Just to be sure

So it posts as only 2gb? +1 on double checking the correct slots are being used. Does it still happen when you turn the speed down to 1066 cas 9? If none of these fix it, it could be the board being warped due to poor mounting - try running without a case and remounting the cpu cooler.
