Intel motherboard partners have started to roll out the first batch of microcode updates to address the issue known as Vmin Shift Instability. The iconic PC chipmaker blogged about this issue earlier this week, revealing the root cause, the four circumstances in which it occurs, and its 0x12B update to finally fix it. Hopefully, the release of BIOS files by Intel partners is going to draw a line under this long running saga which has caused instability, defects, and failures of 13th and 14th Generation Core 'Raptor Lake' processors.
It is now well established that motherboards fed Intel’s newest CPUs elevated voltage levels beyond safe limits. Microcode 0x12B is claimed to address all the circumstances which lead to Vmin Shift Instability. Thankfully motherboard making brands like Asus, ASRock, and MSI have already started to release BIOS updates for systems currently in service. It has taken just a few days for these updates to start trickling through, though Intel warned users the process “may take several weeks.” Let’s have a closer look at what has been made available, so far.
