AMD A10-7860k quad only 2 threads working. Half CPU alseep.

Why are 2 cores/threads of my A10-7860k at 14x and the other two at 36x.?

 

hwinfo64 latest version beta, report, under stress CPU-z 4 threads..2 cores at idle 14x 2 at 36x

 

msconfig/advanced, nothing ticked for processors.. Device manager shows 4 cores

 

GPU R9-280x pcie-3 8x not 16 never shifts regardless generation.

 

GB MB GA-F2A88xm-HD3P bios version 2 supports CPU according to GB website../ is latest bios. supports CPU.

 

Was functioning ok until CPU change..properly..changed CPU back too A8-6600k it's not only working 2 cores. Freah win 10 home x64.. all updates all drivers latest.

 

have unparked cores, rerun util says unparked, still problem persists.
