This should have been there to begin with. Not every user is going to update their BIOS.

This probably invalidates all benchmarks? (CPU can't boost as high with lower voltage?)

according to the statement only applies to overvolting, shouldn't effect stock , the msi statement implies that its being caused by people running a positive Curve optimizer or a vrm voltage offset.
however I don't really buy it , people adding +50-100mv isn't going to cause your cpu to melt, Seems more likely that somebody screwed up, and there is a legitimate voltage regulation issue on those bioses. there is very little if any difference between the x3d and regular chips package wise, and of course all cpus have temperature / current limits, to prevent such a malfunction, smells fishy to me.

Just my luck, I literally just built a 7800X3D system Saturday and then spotted this issue the next day. Wasn't really considering this to be an early adopter situation since the AM4 5800X3D and the AM5 platform have bee out for some time without issues, but I guess I was wrong.
Crossing my fingers it's just a bios issue but, I'm a bit skeptical. Therefore, I'll be dropping in a 7600X to run until investigations into this matter are concluded.

Just don't touch the stock voltages and you will be fine.

7800X3D just launched 3 weeks ago, and "stock" EXPO voltages for 6000MT DDR5 can kill them in less than 3 weeks.
That should probably invalidate benchmarks with 6000MT DDR5
Maddness
I have a very hard time believing that. If that was in any sort of way true, there would be a mass recall of the chips.
Krizby
Ryzen 7000 max RAM speed is 5200MT, anything above that is considered overclocking.

Most reviewers use 6000MT DDR5, only PCGH and computerbase stick to official specification
Undying
Indeed. 4090's ware bruning up and no one recall them as well. This is one of those cases chip being pushed to far.

Question is what voltages are actually safe for long term, how low should people run their DDR5 in order not to burn up their 7800X3D LOL.
user1
the expo voltages probably aren't the cause, 1.35v-1.45v won't melt a cpu, seems more like they fked up, and are sending >3v at post or something like that, that kind of damage requires very high temps.
Krizby
Der8auer said the bulge on dead CPUs are on the IO die, so it probably affect all ryzen 7000 CPU, people should really limit the SOC/MC voltages just to be safe

Buildzoid said Its not soc becouse vrm will probably shut down before it cause any damage, its the vcore itself.
user1
that is only true if the vrm controller is programmed correctly, and that is where I suspect the problem lies, if you've ever messed around with any vrm controller, you can litterally insta-fry if you put in the wrong value. and vrm based over current protection has to be enabled, which is not always the case on motherboards.
I for instance once had a bug with an asus board where if you set the soc voltage with an offset , and left the value empty, it would set the soc to 1.55v ( on am4 verified with a multimeter) , and it would persist even after boot failure recovery.a mis-programmed vrm value can be deadly.
