AMD Releases Second Official Statement Regarding Ryzen 7000X3D Issues
AMD has today released another statement to the press, following on from controversy surrounding faulty Ryzen 7000X3D series processors - unlucky users are reporting hardware burnouts resulting from voltage-assisted overclocking. TPU has provided coverage of this matter this week, and made light of AMD's first statement yesterday. AMD ensures customers that it has fully informed ODM partners (motherboard manufacturers) about up-to-date and correct voltages for the Ryzen processor family - yet user feedback (via online hardware discussions) suggests that standard Ryzen 7000 models are also being affected by the burnout issue - this side topic has not been addressed by AMD (at the time of writing). This second statement repeats the previous one's recommendation that affected users should absolutely make contact with AMD Support personnel:

AMD Statement"We have root caused the issue and have already distributed a new AGESA that puts measures in place on certain power rails on AM5 motherboards to prevent the CPU from operating beyond its specification limits, including a cap on SOC voltage at 1.3 V. None of these changes affect the ability of our Ryzen 7000 Series processors to overclock memory using EXPO or XMP kits or boost performance using PBO technology. We expect all of our ODM partners to release new BIOS for their AM5 boards over the next few days. We recommend all users to check their motherboard manufacturers website and update their BIOS to ensure their system has the most up to date software for their processor.AMD has released AGESA updates to involved hardware parties, in hopes that motherboard vendors will distribute newly overhauled BIOS firmware updates to end users. AMD recommends that customers keep a watchful eye on mainboard download pages, reflecting advice already given by its many board partners.
Anyone whose CPU may have been impacted by this issue should contact AMD customer support. Our customer service team is aware of the situation and prioritizing these cases."

I did not have CPU, then used flashback from 801 (bulk) to 1406, then all reports came up and i applied 1409, today 1412, i feel bad... a Bios has not to be updated, but only if needed.
A lock to 1.1V max would be okay also imho.
Vsoc is CPU side.
You can have SOC @1.2V and memory @1.35V+.
This is what MSI said about the issue. "As soon as EXPO is enabled, the CPU SOC and CPU VDDIO/MC voltages increase to 1.36-1.4v, sometimes boosting to 1.5V in Windows, causing instant death on the X3D."
So the cpu soc increased voltage to 1.4v because many ddr5 use 1.4v expo for overclocking and overvoltage.
I'm not sure what conclusion buildzoid came to in his video, but no evidence so far clearly points to VSOC. VSOC max current draw remains low on chiplets. The visible evidence of damaged pads and areas are all far away from VSOC pads and IO die areas.
Judging from AMD's multi-stage reaction to the reference Navi31 vapor chamber problems, I'm waiting for a couple more statements before they finally, actually discover the real problem. I doubt that very much, considering there are clearly samples of Raphael out there that require that VSOC to hit 3000MHz UCLK. It's not like they got rid of IO die silicon quality variance overnight. There is literally no relation between VDDCR_SOC, VDDCR_MEM, and VDIMM. Memory controller, which they are referring to in the quote, is still subsumed under VSOC rail.
The 1.4V on EXPO kits is for VDIMM. The board vendors just choose whatever number they please for VSOC that they think is necessary to support EXPO when it's enabled.
FYI the vendor that push 1.4V on some board is indeed Asus.
AMD just doesn't want to throw a particular partner under the bus.
Gigabyte is second place @1.35V+
MSI and Asrock usually apply around 1.25V.
Fact is that is enough even with 64GB of DDR5 6000 CL30, on the X670E PG.
They're just saying that VSOC spikes far beyond what is set, and blaming damage on that (considering that VSOC and minor rails have literally nothing to do with Vcache, not sure what it is supposed to have to do with X3D parts specifically).
Every other voltage setting to up to the motherboard discretion.
If you are referring to the alleged bug of BIOS copying VDIMM into VSOC and VDDIO, 1usmus does have a tweet mentioning it, but none of the board vendors make reference to it.
In any case, there are a lot of 1.4V EXPO kits out there, but if it still exists such a VDIMM=VSOC bug doesn't seem to be a widespread one. If it was a major AGESA bug, then everyone with a decent Hynix kit would apply EXPO and immediately see 1.4V SOC set, which is not the case. So maybe board and/or BIOS specific. The board vendors are more hinting at a different form of VSOC overvoltage.
Not sure about the other vendors, but MSI's response seems to be removing manual and positive offset voltage adjustments across different rails. Which makes a lot more sense than AMD pinning the blame on VSOC, MSI's focus seems to be on dying X3Ds in particular, and VSOC has nothing to do with V-cache.
To be honest, AMD should have just kept the hard cap limitations that were on 5800X3D (hard Fmax limiter, hard Vcore limiter). Either they removed those protections for Raphael-X in the spirit of their advertised "overclocking" to generate more interest in the new X3Ds, or AGESA is bugged so that the protections are worthless, or the board partners fucked it up.
I really have a hard time believing anyone should be running greater than 1.3v, the benefits are few and the dangers are seemingly many. I agree there is likely more to the story here, but I personally wouldn't be running over 1.3v SOC until we know the whole picture. I'm not a fan of disabling features either. Perhaps they could just plaster a big warning on voltages past a point, and trip some efuse or something that I'm sure they could check warranty wise. Yes, if their obeyed and the alleged bug of copying VDIMM as SOC voltage isn't real.
My VDIMMs run at around 1.35v in EXPO, so even if the board did do that, hopefully nothing would just explode.
