Gigabyte EX58-UD5 Memory Problem

[zom247]

I recently installed Windows 7 and now I have a problem with my RAM. CPU-Z shows all sticks installed (6 GB) but in system it just shows 6 GB (2GB usable). I've tested the sticks with memtest and no problems there. Anyone else using this board come across this problem? I'm using the F7 BIOS and some Corsair XMS 1600 Mhz RAM.

Have you got a Memory Gap Feature in your bios?

Don't think so but will have a look. Been reading other posts elsewhere about this problem and they mention memory remapping but can't find anything in the BIOS like that. It's probably named something else!

Can I ask what version of Winows 7 have you installed? If its not 64 bit it wont use all the RAM anyway and that may be a problem? Also where have you lost this ram in Windows or is not showing on the POST screen?

Win7 x64 and it showed up in POST and in system it just said 6 GB (2GB usable). CPU-Z also showed I had 6 GB installed. I've RMA'd the board now so just wait for them to test it and get back to me.
