Blacklisting defective RAM region

Anonymous

I have a question on how to actually blacklist a bad region in RAM in Windows 10.
I came across this Microsoft Docs page that mentions that now I have to make a binary value in registry that is an array of 64bit little endian integers representing the bad RAM pages.

Or can I do it the old way through bcdedit and cmd as admin?

Anyways none seems to be effective because I set the registry value, but windows seems to be still accessing the bad region and I get bluescreens from time to time :(.

Moreover, I was not able to do the blacklisting using bcdedit because {badmemory} store is missing ,that is

What should I do exactly?

For information:

  • I am running Windows 10 version 21H2.
  • My bad ram region starts at 0x7c6dc010 and ends at 0x7e6e0318
Windows for home | Windows 10 | Settings

    Unfortunately, the returned number is 3, meaning I don't have ECC memory. Is there any other way to blacklist a defective RAM region in windows 10?

    I am planning doing this, but it is not possible right now, when I need to use my PC.

    Hi, thanks for reaching out! Sorry about the frustration encountered and please allow me to assist you.

    Predictive Failure Analysis (PFA) requires Error Correction Code (ECC) memory. Please ensure you have ECC memory installed. You can check this with the command "wmic memphysical get memoryerrorcorrection". The return value should be between 4 to 7 if you have ECC memory.

    Please let me know if I can help you further!
