I got Gigabyte GA-EX58-UD3R MB and 2x2gb Supertalent 1333 ram and I have this problem.
If I manually don't set the freq to 1333 in bios I get only 2 GB ram and working on 1066. When I set the freq to 1333 I get all 4 of ram until power off. If I turn off the PC and then power it back on I get 1333hz ram but only 2 and in Win 7 x64 saying 4gb but 2 usable. What might be the problem?

I updated to latest bios and still the problem. I read on the net cases of bent processor socket pin but its weird that every time I change ANYTHING in the bios again it shows 4 GB @ 1333 until power off.

Any suggestions?

Thanks, S@
 
Fair amount of this kind of thing going on with several different causes or speculation as to what is causing it.

Two things come immedately to my mind and they need to be checked out an eliminated as possible problems before digging much deeper.

Could you give us a link or post the exact model number of your ram so we can look at the specs. One common issue is that high performance ram wants a litttle more voltage than motherboard default to work. Have you set the dimm/ram voltage and what is it at now when you are having the problem.

It never hurts to run memtest86+ on the ram once you are certain that the voltage is set properly to just make sure the ram itself is not defective. If necessary run on one pair of sticks at a time.
