Need to check my memory controller on Ryzen 5 2600 cpu. The ram sticks is ok but my system only detects 50% of the usable memory. BIOS detects 8GB + 8GB but only count 8GB as usable and not 16GB. BIOS is reset and updated. I'm absolutely sure that the memories working correctly to 100%.
In Win 10 pro 64-bit there is 16GB and only 8GB detected as usable memory.
