Thought I'd try my luck here as I don't seem to be having much luck so far.
I've just upgraded my PC to the following parts
Mobo- GA 970a D3P
CPU- FX- 8320
Ram- HyperX fury 8gb X 2 kit
Gpu- Gigabyte Hd Radeon 7950
My problem is Memory atm, 16gb installed, BIOS, speccy, Cpuz and windows all recognised the 16gb but only 8gb was usuable and in single channel not dual channel. I tried most things people had suggested to try, virtual memory off, memory setting in advanced boot options, made sure all overclock settings were off, checked CPU pins ect, check each ram slot ect.
Changed the ram speed to 1600 instead of 1866 as I read that my mobo only supported 1866 per channel. Nothing worked. So I decided To do a clean reinstall of windows as I hadn't done that with my new parts yet. And to my surprise finally the full 16gb was usual with windows and showing Dual channel now.
Turned my PC on today and I'm now back to square one 😩 The only major update I've don't since my clean install was a update from windows last night - currently uninstalling this to see if that might help.
if anyone has any suggestions it would be most appreciative.
