I'm trying to get GA-P55-UD6 to work with 12 gigs of RAM. I'm using 2 Corsair TR3X6G1600C8D kits (3x2GB). This memory is listed in the supported memory list of the montherboard. But...
4 sticks - all works fine. BIOS and Windows report 8 gigs of RAM
5 sticks - it's weird - BIOS shows 4 gigs of RAM and Windows boost and shows the same
6 sticks - video doesn't initialize, speaker yells and POST code LCD on the mobo shows C1 (which quite predictably means detecting memory...)
Originally the mobo had P3 BIOS version. Upgraded to P4 - same stuff. Tried enabling and disabling XMP - same thing.
It doesn't seem to be tied to any particular memory stick. I've tried to rotated them and results are always the same. 4 sticks work fine. 5 detect as 4 gig rather than 10 and 6 don't work.
Has anyone successfully installed 12GB of RAM in this mobo.
My video is EVGA 280GTX and CPU is i7-860 if it matters. No overclocking whatsoever - everything runs on stock.
PSU is Seasonic 650W but I doubt that it is the problem.
