This beta seems to fix the L3 cache bandwidth benchmark on my 5900X on Windows 11. I would like more people to validate this though.
This is the forum thread linked by the article "AIDA64 Download Version 6.50.5819 beta" https://www.guru3d.com/files-details/aida64-download.html , I don't know if this is intended or an issue. Version 6.50.5819 beta of AIDA64 does not show the L3 bandwidth benchmark issue on Windows 11 on my rig. Therefore it looks like it was not a Windows 11 problem, but an AIDA64 bug that has been somehow fixed in this beta. But for confirmation I would appreciate if more people can validate if Version 6.50.5819 beta of AIDA64 fixes the L3 cache bandwidth benchmark for their 5800X/5900X/5950X cpu too.
