Need some help regarding enabling TSX

Intel 10th gen does not have TSX support at all. The Intel website is also known to be wrong regarding TSX support for other CPUs.
TSX is more relevant for stability nowadays, but your CPU doesn't have it so you can't enable it, regardless of Motherboard BIOS or CPU Microcode.

Interesting info there, just out of curiosity, and because I see you are an admin here and know much more than I on the subject; have you first hand tested machines that do have CPUs with TSX working vs more modern faster processors that don't have TSX working to see any notable performance differences between the two?

Thanks
