[Question] Degredation in Raptor Lake series fix?

[Hexdigest123]

Hi, is there a plan to add the Intel microcode that fixed the degradation issue for the Raptor Lake series? To be specific: 13th and 14th Gen CPUs?
I have seen there were some changes to the microcode, but from my Google search, I found they were for another type of CPU and not the Gen I'm using.

@Hexdigest123,
Thank you for your question.

https://github.com/Dasharo/dasharo-issues is a better place for such inquiries.

Which precise version of microcode are you looking for? Please check the SBOM of recent release notes https://docs.dasharo.com/variants/msi_z690/releases/#v115-2025-09-18 and let us know if you are looking for a newer version, and if so, which precise version you would like to see.

From what i could find it's the following: 0x12B

"For all Intel® Core™ 13th/14th Gen desktop processor users: the 0x12B microcode update must be loaded via BIOS update and has been distributed to system and motherboard manufacturers to incorporate into their BIOS. Intel is working with its partners to encourage timely validation and rollout of the BIOS update for systems currently in service. This process may take several...": Microsoft

It seems you already use the newest firmware patch:

"Updated Intel CPU microcode to 0x12B version"

We already use the following microcode in the latest release:

• Intel microcode version ADL/RPL C0/H0 0x3a 12/12/2024
• Intel microcode version RPL B0 0x12f 17/03/2025

0x12F is newer than 0x12B. Yet even on 0x12B we have observed degradation issues to continue (I can personally confirm as an owner of freshly RMA-ed i9-14900K processor). I haven't yet checked how the CPU behaves with 0x12F microcode.

Well in that case i guess im gonna use it until its broken and switch my CPU back to a more compatible model nothing much i can do
