Hello

I have skylake c236 motherboard + xeon processor + ECC UDIMM memory

 

I run "best practices analyzer" scan on hyper-v role on windows server 2012r2

And got error

 

Title:Use RAM that provides error correction
Severity Error
Problem: The RAM in use on this computer is not error-correcting (ECC) RAM.
Impact:Microsoft does not support  on computers without error-correcting RAM.

 

Then I tryed AIDA latest beta (from this topic https://forums.aida64.com/topic/3404-fixed-ecc-supported-but-disabled-skylake-imc/)

 

DMI

      Error Correction:

Please answer, ECC is full enabled? Why windows server thinks it is not enabled?
