My most recent response from MSI support:
Thanks for reaching out. MSI Desktops use a custom BIOS. We have not had any reports of voltage issues on our prebuilt desktops. If we do have a newer BIOS to provide this will fall under this page : Blizzard won’t let me post the link but it points to a web page I already know about
Turning the PC on exacerbates the issue, thanks to the motherboard sending too much power to the CPU. Any real IT tech would understand that.
How absolutely horrible of Blizzard to warn you that damage is happening to an expensive component in your PC. 
Blame Intel for creating this problem, not Blizzard.
Well Intel and the motherboard manufacturing companies that shove performance profiles down everyone’s throats with default settings, rather than using the CPU recommended settings and limits. But hey, they gotta sell their boards, so they have to make their +0.1% performance bar on the graph look a sliver bigger than the other bars on the short five minute tests, or else they will be review bombed into oblivion by brainrot content creators playing telephone like parrots with the misunderstood/misinterpreted information. Yeah… I could go on a MUCH longer rant about it all lol…
Same here.
Anyone who has msi. Took me 2 days to figure out. Msi center has a tab live update under that it will have update on bios…try that i worked for me…it updated the bios for me and no longer get the fatal error.
I started my career with Intel MCS 48 family processors as an electrical engineer. I spent most of the 40’ish years I worked in operating and communications systems software design and architecture. How’s that for IT experience?
Most people will not be affected by the issue as they do not drive their processors hard enough to exacerbate the problem. WoW does not drive my system very hard so unless Blizzard knows something about their game causing an over voltage condition that I don’t it will have little to no effect on CPU life. So it is horrible causing a panic in the player base by issuing a warning with no rationale as to why they are putting it out and for a game that is unlikely to accelerate CPU problems. In particular Intel readily admits that the fix is not really a fix and that over voltage conditions are still possible after the BIOS is updated. They know at best they can reduce the over voltage condition by some degree but never eliminate it. The problem is in the chip itself which is why Intel extended the chip warranty to 5 years.
I already knew about the issue and when I saw the warning it did make me decide to look into the problem and how I use my computer. It wasn’t WoW that drove me to look for BIOS updates but the fact I use my computer as a DAW to record and mix music. This does put a lot of load on the processor that could exacerbate the over voltage issue. However I don’t think I’m typical of the everyday WoW player.
So again Blizzard is creating unneeded panic in the player base. If they have concerns about the Intel CPU issue then they needed to articulate those concerns so players could make a rational decision on what to do. Not flash a warning to take a potentially unneeded action of updating their BIOS which is not without risks in its own right.
They’re responding to the uptick in support demand caused by CPUs in this family beginning to crash WoW sessions.
It’s both preventative, and (probably more important) disclamatory: if your CPU is one of the affected and you haven’t brought the microcode up to the minimum required level, you’re out of support. As long as you still get that warning, Blizzard is going to waste zero support effort on you.
Download msi center under one of the tabs it has live updates with new bios ( most recent update ) click it and download. It will update it for you.
Not when there isn’t an update available for my system. As has been posted by me and @Asyra MSI does not have a BIOS update for our pre-built systems that use a custom BIOS. We have both posted responses we’ve received from MSI support that more or less dance around how much of an issue this is with this family of pre-built systems. If I start to see problems due to my audio recording usage I’ll replace the processor under warranty and use it while I look for something more robust with an AMD chip.
Where do they state this? They certainly didn’t make any statement in the warning popup and I haven’t seen a sticky thread saying this. There is one post with a referral to the Intel website but it says nothing as to why they decided to push the warning message.
Nah. Too many people with this warning message. This is something on Blizz’s side.
Probably everyone with an affected Intel CPU, as spelled out in the wowhead post linked above. Hopefully not too late for the majority, but we know Intel already extended warrantees for affected units.
Maybe and only just maybe, they are attempting to protect blizzard as a company from any possible court actions caused by this problem.
Oh, we’re all very impressed. It’s always people who think they know more than everyone around them that won’t bother heeding a simple, preventative warning.
Do whatever you like with your setup. Your choices won’t make a difference to players in the forum.
For everyone else, Blizzard is providing a courtesy alert so you don’t waste your hard-earned money due to the negligence of the other companies that put your system together. Updating the BIOS is a simple process and something you should perform when possible (even without a pop-up message). It’ll help protect your hardware over the long term.
I have had the same problem on an MSI rig. I opened a ticket with MSI and I was told that there were no problems with the BIOS. It does sound like the commonality is World of Warcraft.
I can’t say, I’m not personally following this outside of wow, the Intel forums might have more information about what happens in other environments or programs.
There is, which is why Intel released 0x12B and didn’t just stay on 0x129. The commonality is businesses don’t want to put in work and expend money to do what is required of them.
I have a ASUS system that does not have the 0x12B microcode BIOS update yet and haven’t seen anything about a timeframe to expect one.
Is there anything practical someone in my position can do to fix this other than wait?
What board do you have?
They have an asus prebuilt model G16CHR. The most up to date bios, and probably what comes preflashed, is from 8/20/2024 and is the 0x129 microcode update. They have not yet released a bios update for that prebuilt to include microcode 0x12B which Intel rolled out in September.
