Gigabyte X58 U5 problem

[RB racing]

Just finished my new build and I'm having issues with it locking up on me?
Did the bios update Win 7 updates. I have 6gb of OCZ DDR3 1600 V6G 8-8-8-24 Windows shows 6gb installed but bios shows only 4gb as usable. Could I have a bad ram slot?
I haven't changed any ram settings in the bios yet either but shouldn't it show the full 6gb's ?

Thanks.

sounds about right

Do you have 32-bit Windows 7 installed? If so then the OS is limited to only 4GB of addressable memory. Install 64-bit version of OS to fully use all 6GB.

Looks like a bad module. Took the second and third module out and it booted fine and didn't crash. Replaced it with another module and it wouldn't boot. Tried all different combination to make sure the slots were o.k. and I can get it to detect the ram in each slot but when I put that one module in it gets wonky, sometimes it boots sometimes it won't.

Better that than the M.B. I guess will have to get an RMA and try again. I have Windows 7 64 bit installed.

rma ram time

Well it was stable for a while but it's still freezing up on me even with one ram module in. Seems to just freeze at random times. Some times it will boot other times it won't?

I would try setting the RAM to 1066 and see if freezing still occurs. If not maybe the OCZ modules at the rated speed are incompatible with the motherboard.

I have it at 1066 and I checked Gigabyte and my ram was listed for this m.b.
I read on NCIX where someone else had bad OCZ modules that were replaced and everything was fine after. I'll try that first.
