I have a amd 8350 processor gtx 970 and 12 gb ddr3 4 x 4gb 1333 all same speed gigabyte 970a-ds39 only 7.96 usable.
Windows 7 ultimate 64bit
I had 2 x 4gb installed and 8gb usable and installed another 4gb ddr3 and now only 7.96gb usable have tried all sticks in all different slots and new ram with one of the old sticks at a time and 8gb usable but when all three are in together 7.96 usable.
Tried msconfig and unchecked max memory off and tried on and turned off again.
Shows results on cpuz as running on single channel cant find options for duel channel reset bios to default settings and no integrated graphics bios updated to latest version.

any help would be appreciated thank you
