ASUS today became the first motherboard vendor to release UEFI firmware updates that encapsulate the latest 126 microcode update by Intel. This microcode update is Intel’s response to the stability issues plaguing 14th Gen and 13th Gen Core desktop processors based on the “Raptor Lake” or “Raptor Lake Refresh” silicon, which was caused by an improper implementation of the on-die power management, which caused high voltages to run through the silicon, causing their physical degradation over time. If you are already experiencing stability issues, you should be able to claim an RMA or service under warranty, since your processor has already degraded. If, however, your processor is new, and is stable with all kinds of workloads, including games and compute-heavy productivity, then this UEFI firmware update is crucial in preventing its degradation, as it corrects the issue. Safedisk, a professional overclocker associated with ASUS, posted a list of ASUS ROG and ProArt motherboard models based on the Intel Z790 chipset, with links to their firmware update files. It stands to reason that the company is releasing these updates across its other product lines, such as TUF Gaming and Prime.
You can find the list here.
If you don’t find your motherboard model in that list, keep checking the Support section of your motherboard’s product page on the ASUS website, you’ll either find it there, or one of these days the company will put it up. This aligns with Intel’s timeline of a mid-August release for the microcode update.
