Mem latency over 1000 when VBS off

Logs posted below

 

---------

On my 9700X + Gigabyte Aorus Elite, 16Gx2 6000 C28 system ,

Win11, 10.0.26100.3476

VBS off

AIDA64 7.60.7300 got that incredible result, as well as CPU latency increases

By https://github.com/ChipsandCheese/MemoryLatencyTest/releases , the second pic

By intel MLC, the 3rd pic.

If I turned VBS on, AIDA64 back to a normal result.

I don't know which is correct.

With both VSB on and off, in AIDA64 please press Ctrl+D --> CPU Debug --> CPUID & MSR Dump. Attach the results as a TXT file to your post.

Thanks,

Thank you for the test runs.  I'm afraid we didn't find anything meaningful there.  We're puzzled, this is an absolutely unique phenomenon that we've never seen before and one where we have absolutely no idea on what could the cause could possibly be
