Nah, the RAM voltage is unrelated, that's the voltage which is supplied to the RAM sticks. If that was an issue it would be the RAM being fried not the CPU/socket. The SoC basically contains the memory controller of the CPU among other things, which is why the SoC voltage also gets raised when you set EXPO/XMP, as the memory controller will also be stressed more when running ram at higher speeds/tighter timings.

Ok that's what I thought, so because EXPO/XMP profile is disabled, even though I am running higher MHz and tighter timing the SoC voltage should still be at default (though worth double checking)

There is another Reddit user with a blown 7800x3d, says he built the pc and it went to bios fine but as soon as he tried to boot windows the 7800x3d went Pop!

It does concern me just how much voltage must be getting shoved through the chip to make them die so quickly - and how hot they must be getting to deform in this way.

To be honest MSI is the only manufacuturer I haven't personally seen a burn out from, but I was watching buildzoid and he said he had so i'm erring on the side of caution really. Rather do that and end up with a burnt cpu, lol.

MSI put out a notice the other day that their latest bios addresses this issue but it seems they might have thought it was a different cause? They specifically mentioned blocking being able to do positive offsets so that's probably why the SoC currently remains at 1.35v with EXPO on.

Makes you wonder what the real story is, hopefully we'll see something more full from Steve @ GN.

So changing the motherboard to an MSI one won't actually fix the issue then. That's good to know. I wonder if the memory timings error is related to this in some way? I have no idea.

I'm sure Steve is doing a deep dive as we speak. :cool:
 
I've run 1.35v without issue since Am5 launched on my 7950X for 6 months or so.

Now running 1.2v with the 7950X3D, although I was running 1.35v for the first few weeks. I've also tested up to 1.4v while running 6400Mhz - without any issue though this is overclocking so at your own risk etc.

I'm now currently running 6200C28 and testing stability at 1.125v, albeit on the older 1004 BIOS as that works perfectly for me. I also tested 1.100v SOC, but the system didn't complete post sometimes so I increased it a little.

I sync up the SOC and VDDIO voltages too, and I don't use the iGPU so no harm in putting VDDIO to a lower voltage. 1.25v should work for everyone, but its possible that many can lower it even further than that if desired.

If your system and memory settings are 100% stable, folks can certainly experiment with using a lower SOC voltage. If using more than 32GB or more than two DIMMs, the amount you can reduce SOC voltage before encountering stability issues will be less.

Community Notice - ASUS AM5 motherboard owners

An important update for Ryzen7000X3D processor owners
Several AMD Ryzen 7000X3D owners have reported CPU and motherboard failures. We acknowledge the incidents/issues and have been communicating with AMD to analyze the possible causes. We have also contacted affected users to provide support and collect additional information.
Ryzen 7000X3D processors do not allow for CPU ratio or CPU core voltage tuning (CPU overclocking) but do allow for performance tuning and DRAM overclocking via PBO2 and EXPO memory. To support EXPO and/or memory overclocking at DDR5-6000 and beyond, SoC voltage has to be sufficiently increased to ensure compatibility and stability. The amount of voltage required varies between CPU samples. Some processors are more sensitive to overvoltage than others, and some are capable at running higher memory frequencies without needing as much voltage.
As confirmed with AMD, any intentional manipulation of these settings can damage the processor, socket, and motherboard. To mitigate this, we have been working with AMD to define new rules for EXPO memory and SoC voltage. To help protect the CPU and motherboard, we are issuing new EFI updates to limit the maximum available SoC voltage to 1.3V.
We recommend updating your motherboard UEFI BIOS to the latest release. Please also ensure the CPU is cooled adequately. Our recommendation is to use at least a 240mm AIO liquid cooler or high-performance air cooler.
If you have been affected, please do not hesitate to contact ASUS support for your region.

Any additional updates will be noted and updated in this post.

FAQ -

1. When are the new UEFI releases going to be released. Our expectation is to have the UEFI BIOS updates posted and available through the service and support website within the next 24 hours.

Thanks for posting this btw.
 
My 6200MHz ram isn't stable enough in my case. But today Asus give me another bios for STRIX 670E-E v1301 beta for max SOC voltage up to 1.3V.
I tested it and works ok ang have great performance in testers. Best scores I ever had.
I'm using my typical settings - EXPO tweaked and PBO 80*C.
In my case voltages with newest bios looks like this:
- old bioses with expo enabled - readings from ZENTIMINGS - SOC 1,300V,VDDP 1,148V and MEM 1,4V/1,4V/1,8V/1,1V
- bios 1301 with expo enabled - readings from ZENTIMINGS - SOC 1,244V,VDDP 1,148V and MEM 1,4V/1,4V/1,8V/1,1V
For now I didn't tweaked memory and have again faster boot options enabled - power down enabled and memory context restore - both ENABLED.
 
Just noticed a TUF beta bios 1412 on the asus page that specifically mentions a SoC 1.3 cap, are beta's worth the risk you reckon? Or just stick latest release and manually lower the SoC?

Good spot. It's not on the UK ASUS website yet. I really don't know dude. I think I'll wait for the non-Beta.
