Based on the dmesg output alone, it looks like ECC support flat out does not work on my system. However this flies in the face of what I see in Windows. Basically the wmic, HWiNFO64 and AIDA64 results for my system are the same as these
The previous post mentions issues being resolved in 4.11.3. Do the fixes extend to 5-series kernels? Is there anything else that needs to be enabled under Linux ECC memory, or should it Just Work™?
