I've just recently installed 8MB of G.Skill DDR2-1066 (2048 x 4), P/N F2-8500CL5D into an ASUS Crosshair II Formula AM2+/AM2 NVIDIA nForce 780a SLI HDMI ATX AMD Motherboard.
The problem is that the both the BIOS and Windows only shows 6 of the 8MB installed.
Any ideas whats causing this?
Note: The Motherboard bios has been updated and the DDR type selected in the bios "DDR1066" with all other setting on automatic. I dont think that there is another bios update as this MB is about 2 years old.

More aboutmemory reporting whats installed
Are you running 32 bit or 64 bit Windows?
32 bit.... however as I said, the bios isnt even showing the 8MB installed so I dont expect that the OS would ever show it.
Note: I'm aware of the 32bit memory limitartions and plan on changin my OS at a later date.
