Here's the issue:
AMD FX6100 CPU + Gigabyte 990fxa-ud3 mobo
(Also have tried an Asus M5a97 mobo but returned to store)
2x4gb Ram (Tried patriot and gskill from a different computer, both at 1333)
650w PSU
AMD 6870 gpu
The bios will only see 4gb of ram, windows sees 6gb of ram but only 4gb is usable (64bit Win7). Linux only sees 4gb of ram.
If we take the SAME ram and put it in the SAME mobo but swap out the CPU for a PhenomII 965 then the ram shows up fine.
We have updated the bios and tried all available versions from Gigabyte's website.
Does anyone know what's going on?
