I had an ASUS rog strix b550 gaming F motherboard with an 5700X, it would randomly freeze and then resume or reboot.
After a look on the HW monitor it was clear (see cpu vdd). At first I thought is had to be a wrong measurement but my multimeter confirmed it.
I contacted ASUS, they told me it could be the cpu requesting wrong voltages, so I should test it with another cpu, in retrospec that was insane, but I did it with a 2700x from my other system.
RIP
Now the motherboard was send back to the retailer and I got my money back for my motherboard but none of the 2 CPUs are now stable on my other system (which is stable otherwise, the 2700x was stable there before and i got a 2600 which also is still stable there). Sometimes they hang on post, other times bluescreen, and sometimes freeze everything but the mouse can move (reset required), they may work for an hour or so.
I contacted the store, they told me they needed a signed document from a tech that there was damage to the cpus caused by the motherboard and then they would think what they could do. I couldn't get a tech to sign it, however I thought contacting AMD was simple (I can't find an email or navigate their support maze*, so I can get it from them that pentium 1 voltages are damaging to the 7/12nm cpus)
Does anyone know the amd support email and/or where to find the datasheet for these cpus that will have the maximum voltages writen on them by AMD?
Notes the 5700x was from the same shop, the 2700x is from a different one and the warranty has gone out along with 2 power pins that got stuck into the faulty mb socket (i managed to remove them with tweezers)
* Maybe it is simple but at this point I don't have a clear mind.
