TME-MultiKey enable in Intel 12th CPU (12700k)

Hello,

I recently reviewed the specifications for the Intel 12th generation CPU, and was intrigued by the introduction of the TME-MultiKey technique. Consequently, I purchased the Intel 12th gen CPU (12700k) with the intention of activating the TME-MultiKey feature.

However, I'm unable to locate the relevant configuration within my ASROCK B660M Pro RS BIOS. Additionally, upon inspecting the CPU in my Linux host OS and reading the values in the MKTME MSRs, it appears that TMEMK is not active.

Is there a method to activate the TMEMK on the Intel 12th gen CPU?

Alternatively, should I be exploring hidden BIOS configurations or considering modifications to the UEFI firmware?

I would be contacting asrock regarding their bios.

I agree. Since this is an 11th gen BIOS updated to support 12th gen processors, features and parameters specific to them are often missing. ASRock will need to enhance their BIOS to support this parameter.

Hope this helps,

Thank you. I'm looking for more recent motherboards that might support CPUs beyond the 12th generation.
