I need to use xmp profile or 1600mhz + 8-8-8-24 or 1866mhz+9-9-9-24
I try to set RAM voltage to 1,65v and CPU vtt voltage to 1,1 but it dont helps.
When i have black screen and PC stuck, in system log I see error "Initialized error report IOMMU".
All tests and benchmarks pass OK. OCCT test pass OK. Problem happend in certain games(battlefield and same) and adobe premiere.
