Clipped due to a max of 20,000 characters. I also regularly get PCIe errors reported on all devices, and even errors saying that ECC errors have occured, on a different DIMM more or less each time. Considering how many of these issues are directly tied to the CPU, is it the one most likely dying?

Hello @Jord ,

Can you run the following and post the output:

• dmesg | grep -i error

We would like to see more of the errors being reported.

Can you also reseat all of your DIMMs?  And have you reviewed, and ensured you're follow, our DIMM population guide?  https://developer.amd.com/wp-content/resources/56502_1.00-PUB.pdf

Are you running this on an OEM box?  If so, check the out-of-band management controller like the Dell iDRAC or HP iLO, they will also give you lots more information about hardware failures and they typically will offer support as well.

Hello @Jord ,

If none of the other suggestions have helped, I suggest reaching out to your platform provider.  This could be a voltage regulator going bad just as much as it could be faulty silicon from what you've shared so far.  The platform BMC might provide more details as well to help diagnose.
