PC Processors

[Andrewww_1003]

I have a 9700x and TUF GAMING B650M-E WIFI

when i updated my bios yesterday my task manager shows that my CPU has only 8 threads instead of 16

I tried turning off eco mode in the BIOS and searching on Google for a solution, but to no avail.

Appears AMD SMT (Simultaneous Multi-Threading) may be disabled.

Here's your BIOS manual, page 34, SMT control.

If that doesn't fix it try going back one previous BIOS version.
