Would you be able to check what voltages are reported if you set soc and vddio to auto and Expo Enabled on this bios?
Would be interested to see what thresholds have been set...

Sure I can when I'm home from work later.

Dunno if its related to the burning ryzen issues but gb just released a new bios tho i think its a beta as has a b on it.

For the b650 mb. Should i grab that when i finish building mine, or wait for a non b version? The notes just says optimizations for the x3d series, so might not be for all the ryzens of the 7x series.

Bios 1302 (beta) is avail for the x670e Hero. I will be installing it so will report any issues.
SoC voltage for Ryzen 7000X3D series limited to a maximum of 1.30V to protect the CPU and motherboard.
Before running the USB BIOS Flashback tool, please rename the BIOS file (CX670EH.CAP) using BIOSRenamer.

With manufacturers putting in lower SoC voltage caps... is it likely that the memory QVLs will have to be adjusted? Are we going to see kits that were formally certified dropping off them because they needed a really big whack of voltage to get them stable?
Kind of have 2x32 G.Skill 6000 c30 sat unopened on my desk while I await other parts, suddenly nervous that this build might no longer be going to work...

1.3v still sounds a little high to me, especially when my system is running faultless at 1.15v SOC, MC voltage I've dropped to 1.25v, I tested stability last night although I didn't have much time, I left memtest pro running for 5 hours without any errors and then looped CBr23 for 30mins without any issues.
The beta is there for my x670e gene too, I may flash it, might just wait for the final, I think a lot of us have been guinea pigs enough already.

Flashed the bios on my MSI B650 Tomahawk last night. The bios was released on the 14th of April and it has the voltage protection. It appears they have known about this for a while.
Yep, i'm sure.

The latest bios for my MSI B650 Carbon dated 18/04/2023 does not have any voltage protection. I updated and re-enabled EXPO. Still forcing 1.35v

I did think it was odd. Im guessing msi are slow to bring out bios revisions in regards to this. I think Gigabyte and Asus both have.

Scratch that, i was updating the DRAM voltage by mistake
. They changed the layout on the update. Enabling AMD overclocking on the SoC then manually changing it down works just fine.

Great, so they made it worse!
Can you take the CPU out and check the underside for discolouration or lumps?
Part of the issue is to do with the Load Line Calibration associated with SoC.
Every board manufacturer has slight differences on how well the VRM responds to load (based on the precise VRM design, number of phases, and bios settings).
Information is coming out now showing that some boards, even though they were specifiying 1.35-1.4v for SoC, they were spiking past 1.5v in windows when cycling to/from idle to load....i.e. they were overshooting their target voltage.
-So you have EXPO which called for up to 1.4v (that upper limit tentatively set by AMD by the looks of it) - but this was not validated on X3D chips only X series....and then i doubt the level of validation as we are talking out of spec values here.
-On top of that you had some bios's with poor accuracy on what they were actually setting (specifiy 1.4v and you were actually getting 1.45v)
-In addition to that you have overshoots under load/idle transitions.
It's no wonder the bloody CPU's have been blowing up. As under the worse case scenario above, you would be looking at around 30W of SoC power, vs the stock 9W - over 3 times what it should have been drawing. and a voltage spiking to over 1.5 times rated value.
If they can't get their house in order they need to dial back SoC to around 1.2v max i'd say as not every motherboard seems capable of accurately sticking to a set value.

As per the video by der8auer its not an issue thats limited to x3d chips its the entire line up thats prone to this issue.

If every single AM5 CPU is at risk then I guess it's not much of a problem? Units sold vs units that have died with this issue.
Could be user error again - just don't touch the pads with your unclean fingers.

The F6B that i mentioned in above has now been removed from the bios page of my mb, i wonder why. It just came out the other day. Either they pulled it for reasons or maybe they are dropping it and trying to add in the soc fix for it if it wasnt in already.
Tbh it would be outright crippling because the 7000s need good memory speed so badly... if they're forced down to 5200 they'll end up swapping place in any benchmarks where they had a close lead over an Intel chip.

I don't know what they're doing. Say they've released updated bios today, but they've pulled everything from the B650 Aorus Elite except the F4 version which is an old bios :/
