WHEA-Logger ID 47

[spidertech]

Hi

I have a problem with my Windows Server 2012 R2.
For some time in logs there is a lot of lines about:

WHEA-Logger ID 47

„Fixed hardware error has occurred”

Part: Memory

source of the error: Revised memory check

logs:
ErrorSource 1
FRUId {00000000-0000-0000-0000-000000000000}

Error is occuring every second. Memory was not replaced.
Memtest shows no errors. How can I fix the issue. Should I replace the memory?
