Sounds like both companies use the same vendor for their voltage regulators and accompanying control software. Maybe that software contains a bug where it will accidentally set a much higher voltage that requested, leading to this issue.
Still you would expect the teams that builds the UEFI BIOSses at both companies to check what the actual voltage being set is and not rely on vendor supplied information. Guess we'll see new BIOS versions soon from both parties.
BTW: Other motherboard vendors might have similar issues, they just haven't been found out yet.

Most likely they use the same method of "increasing performance" by auto overclocking the CPU and they royally fucked up the voltage.

lol, that's why prefer buying fixed hw late at discounts anyway than beta test early samples at extortionist prices.

Haven't CPUs had dynamic frequencies since the turn of the century? That would have been coupled with dynamic voltage regulation. Seems like too old and established technology for it to suddenly have weird and hard to solve problems now in the 20's.

that's not vcore but memory controller voltage what's causing the damage. asus prove again they're a premium brand name at premium prices but the quality control is worse than budget msi.

Hilbert i remember your first ryzen 7000 review ,im not microprocessor engineer neither a board designer but 200 + watts and 90 + degrees C is not ok.
90 degrees C was considered a malfunction of the cooling setup.
I remember the times when 70 degrees C was a warning.
You cant suggest something wrong as normal.

Even if it goes up to 1.36v at times i dont think it will damage anything. I dont stress my system enough but for me its always 1.27v after the bios update.

Looks like a new feature to me, how to kill your CPU+Mobo easily so you can get new ones 😀

Strange, shouldn't the MB set maximum voltage values that shouldn't be crossed at any circumstance?
I'm thinking about an AM5 build but this news are making me reconsider...
daffy101
Same here although this doesn't appear to effect all brands of MB I could upgrade to AM5 if I wanted but I think I'm going to wait for a while and see what happens.

software readings were proven wrong in this case.

Isn't expo technically overclocking and out of specs?
I wonder if we should just goes to the basic that overclocking is risky, sometimes more sometimes less.

that's what I want to know?...if I build a new am5 platform and don't tinker with it at all is it still screwed up?

EXPO is an AMD technology developed with various DDR 5 manufacturers as partners. Normally the motherboard reads values from EXPO and applies them - but is AMD and memory here - the motherboard just execute those values.
It's a messy thing....I avoided AM5 for those reasons and went with AM4 for a new PC - I hate Intel big/small architecture.
From AMD: - and fry the chip/motherboard in the process...
Asus, Gigabyte also make boards for Intel cpu's like 13900K that can draw 350W - why there is no incident with XMP/Asus MCE, Gigabyte MCE on Intel?
And by the way AMD footnotes:

reconsider what ? why ? everything seems fine 😀

Funny thing: while AMD on their AMD EXPO page (where, by the way, the foot note with voided warranty is hidden by default) says that "it will void any applicable AMD product warranty", Intel is not so decided on their XMP page: " it may void the processor warranty".

Another funny thing: most people didn't even knew that enabling XMP/EXPO is overclocking- it is just a natural way to obtain rated speeds on those expensive memory kits that can run at very high speed: if all the memory is run without XMP/EXPO than what's the point in buying those expensive kits that can run outside the supported memory on the CPU? AMD itself uses 6000 EXPO memory kits in their marketing materials for AM5 and now they are saying that you WILL void warranty if you use EXPO because it is a form of overclocking??? WTF? So, "it's just marketing suckers!"
And if you disable EXPO on AM5 then benchmark results are, of course, very bad.

Wouldn't worry to much. However, best approach is to manually lower SOC voltage, I've got mine set to 1.175 atm in the BIOS and did some memory benches.

Would it be a workaround to set those timings and values manually like I do on 1st gen Ryzen?

Its easier to enable expo and lower soc voltage manually.
Im just updating to agesa 1.0.0.7A to see if anything is changed.
