Hi.

I have 4gb RAM, 2x2gb sticks, everything is working fine. But for the past week it has been varying. I can play a video game, and all of a sudden it would BSOD or crash, and upon rebooting it would say i have 4GB (2 Usable).

Switching RAM sticks around fixes the problem temporarily, but eventually it crashes back to 2gb usable. I used the windows memory diagnostic tool and it detected no issues, i have also checked the Max memory setting in msconfig and it is switched off. I have also switched BIOS to default, and rebooted, and it still said 2gb usable.

The weirdest part is that without touching anything, not switching ram around, just powering the PC down for the night, it booted up as 4gb today, but I am sure it will crash back up to 2gb soon enough.

My Motherboard: gigabyte ex58-ud3r (RAM in slot 1 and 2, with a gap between)
RAM: Corsair Dominator 6gb (3x2gb series, i only have 2 sticks)

Please help.

Love.

Nonka.

well you will always want to have the ram in either slots 1 and 3 or 2 and 4 to take advantage of duel...

The motherboard is not on the warranty anymore, but since i only have 2 RAM sticks, isnt it possible to have a combination that would work for now ?

I will try that, I have also heard that it might be an OS problem, since it happens at random, after BSOD. I will try to reinstall the system, and change the slots, that should reveal if its the hardware or software related issue, since I tried various slot configurations and it always ended up the same, with a crash and boot to 2gb.
Thanks for help, I'll report back after I try the solutions.

yeah the only reason why I didnt think of it before was that one of the slots is blue, and since I am no PC expert, I assumed that its not used for dual channeling, I will try that config anyways and see how it works.

The problem was a bad ram stick, even though it passed all the memtests. I've tried other ram sticks and they are working flawlessly, thanks for help.
