Several errors reported in Memtest86 - Tests 1,3,4,5,7,9,10 failed

[Avenger1234]

Hello everyone,


First of all, I would like to thank you for making this program and for the continued support you are offering.
I've been having BSODs, crashes while playing for some time now. The bluescreens mostly had the error MEMORY_MANAGEMENT and yesterday, there was an IRQL_LESS_THAN_OR_EQUAL so I ran Memtest86 to see what would happen.
Here are the results. For some tests, namely 3, 4 and 7, all 4 passes had errors. Tests 1, 5, 9 and 10 had one or more passes with errors.

Certification

This document certifies that the Tests described above have been carried out by a suitably qualified technician on the System described above.

I will also attach the complete log in the post.
Should I try to test the modules individually now? Or should I just change both RAM modules?
Thank you for the help!

Likely the RAM is bad.

In your case try testing half the RAM at a time. See the following page for troubleshooting RAM errors, https://www.memtest86.com/troubleshooting.htm

Hi again!
After testing, there were still errors, so I replaced the RAM modules. After running Memtest again, there were no errors anymore, the system seems stable and I did not have any more BSODs so far.
I think the issue is resolved. Thanks again for your help! Have a great day!
