EPYC 7513 melted a part of its heat-spreader

One of our servers had been throwing weird memory allocation, memory access and execution errors on a Linux box we were running.

All of it got fixed however, after we disabled one of its physical cores, which was weird, right? Why did disabling one core fix such an odd mix of errors?

So we decided to replace the whole CPU despite only having lost 1 of its 32 cores.

What we discovered, after removing its cooler however, utterly shocked us.

The CPU had literally melted the aluminum layer of its heat-spreader in two spots, suggesting there must have been some kind of a short circuit in one of the cores, or some other kind of a hardware issue.

In all of my 8+ years of working in IT, I have never seen a thing like this.

Seizure strings vs individual seizures

Hey everyone,

I was wondering -- how common is it for seizures to happen in clusters?

Mine go off about once a month or two, but when they do, they always cluster up - meaning I get one TC, then a break ( don't know how often I fully regain consciousness), then another goes off... Instead of just a single bigger / longer seizures.

Anyone has it similar?

And are there certain kinds of epilepsy more likely to cluster up opposed to others?

Mine is right TLE FBTCS for the record.

Thank you <3
