Originally, this is the kind of stuff that the original overclockers would risk happening right before it caught on?
If I never respond again, AMD got me.
Oh, ok. I thought maybe it warped a bit as it got worse and then went BAM!, all of a sudden burnt up and you now know for sure.
What AMD fixes are you talking about?
Still mind blowing that these chips can even run that much SOC voltage so readily, but because of the heavier RAM EXPO profiles with DDR5, it makes sense. DDR4 XMP profiles would rarely need more than 1.1v SOC. AMD has to make sure that vSOC CANNOT exceed 1.3v on those CPUs at least because it'll fry them.
I was asking because, as far as I know, AMD already released a new AGESA to address this problem.
The AGESA update didn't fix the problem, nor did ASUS' beta BIOS.
That's actually my point. Isn't the ball in the MB makers' court?
The end-user is not seeing any improvements until they properly implement the code from AMD and fix their own crap.
Most users don't have a BIOS version with the latest AGESA yet. The one that supposedly addresses the voltage issues.
The ASUS one was tested by GN, vSOC is still too high, exceeding 1.3V, which was the set limit in that AGESA update. Which is a reason why AMD is now overhauling their whole BIOS standard. Regardless of what AMD does, it is indeed up to the board maker, and ASUS being ASUS doesn't properly follow manufacturing standards, and they add their own garbage into the mix.
Plus, ASUS' beta BIOS that supposedly fixes the issue (but actually doesn't) voids the motherboard's warranty, according to them. So not only does it not fix the problem, ASUS won't help you if their failed fix still results in a damaged CPU and motherboard. AMD would replace your CPU, but ASUS could tell you to ♥♥♥♥ off if you asked for a new motherboard after using that BIOS because they're trying to relieve themselves of any responsibility. Don't know about you, but I'm never buying an ASUS product ever again, I'm not supporting that turdstain corp.
My conclusion - ASUS still pushed it too far, despite AMD's revised specs.
I don't think the move to openSIL has anything to do with these CPU burn-outs.
As of today, some AM5 ASUS MB's received a new BIOS update. Maybe we'll see someone testing it for voltage check. Again.
Watching GN's latest, now. Interesting thing they're doing there.
Their board have always overshot on voltage, that’s just how they did things.
The SoC, like everything, has a limit. In order to get the system running with Expo RAM speeds, the SoC voltage is raised when Expo is enabled. This was setting them to run around 1.3V to 1.35V from my understanding. Some would see brief spikes to 1.4V or even 1.5V I think? The latter was causing issues, and when the 7800X3D specifically released (wondering why this wasn't caught with the Ryzen 9 X3Ds, maybe too few sold?), it became apparent because the X3D chips have lower voltage limits.
My 5800X3D runs at much lower voltages (~1.25V) than my 3700X did (which would run up to 1.4 or even 1.5V on spikes, but again, these values were never used under 100% use so it wasn't damaging to it, but it COULD if it used those voltages under heavy loads).
With AM4 CPUs, the SoC tends to run around 1.05V to 1.1V, at least in my experience (I saw 1.1V on both my AM4 CPUs and that was on two different boards and with a heavy memory configuration, so I don't imagine the values these AM5 CPUs are seeing is normal on AM4).
I made a better thread before this one explaining the issue here.

TL;DR; This isn't a thing to worry about on AM4. Check your SoC voltage if you want reassurance but it's probably ~1.1V at most. The new platform when using Expo is just causing the SoC voltage to get too high. Especially a risk for the X3D chips but also a lesser but still risk for the rest. If you're on AM5 and the SoC voltage is at 1.25V to 1.3V at most you're not at risk either (presuming your particular board doesn't spike it higher like some do; MSI is said to not being doing this but that was a claim put out by themselves so take it for what its worth).
