6gb of ram randomly showing as 4gb?

Hey all, so here's my issues

Today I went out and purchased an Intel i7 960, Asus P6T motherboard, 6gb of Gskill Ripjaw ram, and a 64gb Kingston SSD drive.

So I go home and I install the motherboard and cpu / ram, and boot into my previous windows install to make sure everything is running great before I install my SSD.

Everything shows up perfect, 6gb of ram etc.

I shut down, install my SSD, install Windows 7 Home Premium 64bit. Booted it up, and apparently I only have 4gb now? CPUZ shows all 6gb, but bios, and windows shows only 4gb?

What the hell could have happened ?!

Does it say 3.5 or 4GB useable. If so i have the same issue. What i did was not exact but i oviously rebooted went into bios. I even moved the sticks around. then before i knew it i was running at full capcity. Also you could try only loading 1 or 2 sticks.

Last year I had the same exact problem with my asus p6t se running i7 920. After hours of testing everything it turned out to be a bad motherboard. I rma'd and got back a p6t which is running strong for 6+ months now.

So I tried each ram piece, in each slot. Then added 2, turns out one ram stick wont work in the middle slot, but works fine in the 1st or 3rd. Either way, problem is fixed.
