For posterity, what PSU are you using?
Just lost my 7800X3D CPU on an Asrock board. Craziness, I was also on the latest bios.
Just lost my 7800X3D CPU on an Asrock board
Where’s the last place you remember having it!?
FR though that sucks. It’s a bummer situation. I ended up switching to MSI because I didnt wanna deal with potential downtime.
Oh , the PSU is an EVGA 1000GQ, I looked at the published power curve and possible max draw of all the components and tried to hit the best point on that curve with room for temporary high draw if needed. It’s plugged into a CyberPower PR1500LCD.
The system also has a RX 9070 XT that I’m really not impressed with.
Also, I’m running Nobara linux for now, I tried Windows, just can’t swallow that load of … 8 )
A psu cause seems to be very unlikely to me.
Although in an individual instance a bad psu could cause system components to fail.
However in regards to the Asrock problems it´s not very likely.
In my other topic on the issue i was thinking about a possible socket issue,
given that two main manufacturers of sockets being used across the board Foxxconn and Lotus.
However that presumption is also kinda ended up cold given that it´s hard to build,
a data set on the data that is available on reddit.
Because we don´t know which sockets being used on the so called murder boards.
From what i gather you can actually have two of the exact same boards with either a Lotus or a Foxconn socket whatever the availability was at time of production.
I guess that it´s likely that those boards with different sockets also have different batch numbers.
But yeah it´s kinda impossible to filter that exact data.
Still yeah we did have had issues with sockets in the past.
The only thing we know till know that some of the cpu deaths seems to have occurred,
in a low power state situation.
I wouldn´t be surprised if those particular boards have a bad transistor on them somewhere,
in the power plain causing voltages to fluctuate and eventually killing the cpu´s.
That occurred to me when the murderboard thing started getting press visibility back in March. If there was a simple answer probably it would have been found in the past nine months. While the r/ASRock anecdata everybody’s working from doesn’t seem to include workloads or GPUs, it seems plausible to me correlations might exist with those the way they do with the 9800X3D, certain lot codes, use of PBO, and 1.4 V DDR kits. Since GPUs tend to pull more power than AM5 CPUs, GPU intensive workloads are likely the most influential ones on PSU activity.
It’s entirely speculative but perhaps workload and GPU combinations are one reason why time to failure seems to vary widely. Unlikely there’ll ever be sufficient data to test hypothesis around game or GPGPU power levels, though, much less things like use of Furmark for GPU acceptance testing and thermal evaluation.
One thing about RDNA4 is, based on the small numbers of cards Igor’s has reported measurements for, it appears AMD’s card designs return ~90% of ground current via the PCIe slot rather than Nvidia’s ~65%. So a 9070 XT is capable to put ~270-330 W worth of current through EPS and the 24-pin, comparable to a 4090 or 5080. If the deaths result from voltage, and are thus linked to ground potentials, then 9070 XTs would be the most cost effective way of getting into ground problems.
In particular, the PEG-EPS return path runs along the CPU VRMs. So if the VRM ground references aren’t resilient to GPU current flows the CPU’ll get hit. Also the lowest impedance PEG-24-pin path probably runs under the DDR sockets, which is maybe kind of interesting given the possible correlation with 1.4 V kits. The resulting current distribution’s influenced by the motherboard but might be more a function of PSU cabling and PSU internal layout.
Another question I have here is why MSI started placing auxiliary 8-pin power connectors on their boards. It puts probably five ground pins a bit closer to PEG than the eight EPS pins and makes a triangle with the eight 24-pin grounds. That’s not insignificant to changing a motherboard’s ground balance.
Could also be a manifestation of the tendency to hit stability problems around idle state voltage transitions. Like maybe if there’s degradation while active and then it’s an idle transition which finally makes something blow for good.

Yeah that is indeed something in the realm of possibilities that i am thinking about yes.
Can you provide more details please?
When did you buy that CPU and mobo?
What cooling solution were you using?
Any PBO or CO enabled?
Was EXPO enabled?
Was the iGPU disabled or were you using it enabled with the discrete GPU as primary display?
Did it stop booting one day or did it turn off suddenly while using it? If the latter, what were you doing on it at the time?
What kind of workloads were you running on it?
As I’ve asked in another post, how many of the COD where using GPU’s with that 12V-2x6 power connector? I’m running tests now to find out, simply poor mechanical connections and deviating from the original specs to a lesser cost alternative that can’t handle the demand? 8 )
