Run Benchmark over and over again.  

**Expected behavior**
I would expect to see similar hashrate has the 7742 or 7B12 (ZEN 2, 7 nm)

similar to this bench: https://xmrig.com/benchmark/36Smmu

I have 16 sticks of 8gb dual rank ram.  

**Required data**
 - Miner log as text or screenshot
 
 - Config file or command line: 
 @echo off
cd /d "%~dp0"
xmrig.exe --bench=1M --verbose
pause
 - OS: Windows 10 22H2
