RAM detection problems

[Truth13]

I just got my Gigabyte motherboard back from RMA servicing. When I rebuilt my system, however, I had some problems with my Crucial memory cards (2 512MB DDR sticks). The first time i booted, I got BIOS beeps indicating momory problems. After tinkering around with each card in each socket, I was able to determine that only one socket out of four was detecting memory at all. Not only that, but the socket that was detecting memory (it detected each card when i tried each) only detects 64MB of RAM, when it sould be detecting 512MB per stick, or thereabouts. I have a seperate videocard, so there is no onboard video RAM drainage, either. Is this another motherboard problem, or a memory problem? Thanks in advance for your help!

What's the model of the MB, and the specs for the RAM?

Boy, it seems like so many porblems in PCs need to be solved by trial and error. I guess you don't have any other mem modules to try? Like a couple of 256s....?

One thing, make sure you've reset the CMOS, to give the board a "new try". And beleive it or not I'd start the board once, NO RAM in it, reset CMOS, and try again.

For sure, it's much more likely that you've somehow scrambled the memory-hub controller of the mainboard. If you could try the RAM in another board, that would pretty much prove that.....
