In my case, if the uCode is patched from Windows update, the TSX won't enable even modified Registry
Thanks for explaining why Windows 10 had TSX enabled (with mcupdate_GenuineIntel.dll disabled) and Windows 11 had TSX disabled (with mcupdate_GenuineIntel.dll enabled) for the two images I posted here.

I force updated the Windows Update Microcode patch and BIOS microcode to ensure TSX is disabled for testing :D

Here is my testing result:

1
2
3
 
REG value: DisableTsx ; FeatureSettingsOverrideMask ; FeatureSettingsOverride
BIOS MC: EC
Windows MC Update Patch: KB4589212
 



- TSX enabled (with mcupdate dll, reg TSX enable) [surprising and weird, is it ignore dll in this situation?]

- TSX enabled (without mcupdate dll, reg TSX enable)

- TSX disabled (with mcupdate dll, reg TSX disable)

- TSX disabled (without mcupdate dll, reg TSX disable)



Therefore,
- Windows will apply microcode from BIOS while mcupdate dll not exist
- Does TSX not only depend on mcupdate dll, registry also?
- [EDIT] Different situations will show different results, if CPU-Z / AIDA64 shows TSX isn't supported, you need to check the regedit first. If still unsupported, you should uninstall the MC update patch / remove or rename mcupdate dll.
- @chinobino can you enable TSX through regedit on your Windows 11 while mcupdate_GenuineIntel.dll enabled?

In my case, TSX is displayed with CPU-Z. However, I do not know if it is actually working in the system.

If TSX is displayed on CPU-Z, that means it is working.

Sure, can you tell me the location of the keys and their values etc?

@ritizen I added the 3 new keys and set them to enabled, rebooted and now TSX is enabled in Windows 11 with mcupdate_GenuineIntel.dll enabled.

This shows mcupdate_GenuineIntel.dll & the registry are the keys of TSX :D
I am thankful for your assistance
(Different uCode may not affect TSX instruction)

If Sky new microcode does not come out...
The possibility of coming out will be old version that have not yet appeared.
There is point there. This is natural.
And the possibility of the content like the special version of the example will come out.
It will connected to it.

TSX is better for enable than disable in some cases which are required on TSX. (one of the emulator - RPCS3 rely on TSX instruction to optimise, the huge degraded result show after TSX is disabled). However, there are no any gaming benchmark (except RPCS3) that can reflect the influence of performance.

[Edit] Regarding the benchmark, due to TSX instructions involve some of thread enhancements technology, you will get some different on benchmark score between TSX on and off

In your situation, you may continue to use pre-spectre uCode on your 7900X and without mcupdate dll to perform the best performance.

Skylake-S (1151) has been brought in line with Kabylake and Coffee Lake with microcode cpu506E3_plat36_ver000000EC_2021-04-29_PRD_D912FEAB.bin
