Do I keep frying CPUs?

Hi, a few years ago I had to return an AMD ryzen 5 3600 because it stopped working, now my 5700X3D has just done the same.

The 3600 was tested by AMD and found to be faulty, however, could it be overclocking that has killed them both?

I undervolted them both and they've both been watercooled so even after gaming, temps don't go near 80*C...

Motherboard is an MSI Tomahawk B450 with RAM @ 3600XMP

If there was years between them, I doubt it, just unlucky.

That's what Im hoping!

3600 must have lasted a couple of yours or so, I'm not sure but the 5700X3D is only 5 months old

I have now put the old 3600 (not the broken one) back in my pc and it's working so I do think the 5700X3D has given up, shame.

Is your bios fully up to date?

Strange as over the many many years I have been building or upgrading PCs (personal 1s) I've never had a CPU die on me.

At least you had a spare CPU to test and know its this that has died.

I think I updated the BIOS for the 3600 but not the 5700X3D as it worked without.

It may fail an RMA due to that but I'm willing to accept any causes that could have been my fault.

They will not be able to tell if its failed due to a bios version unless they ask you what board and bios version you are running but you could say anything to that.

Hope the RMA goes well and you get a replacement, if its within warranty then it should not be a problem.

If the replacement 3600 ran for several years and is still working fine now, I very much doubt you (or the board) are the problem. Just unlucky with the 5700X3D. Spontaneous death does seem a lot more common with modern CPUs than previous ones, which pretty much never died once installed.
 
Latest BIOS? Good quality PSU? High quality 24-pin and 8-pin extension cables (if used)? If you're doing everything right I wouldn't worry about it.
 
In over 30 years I've never had a CPU die, so I think it's just bad luck.

Motherboards on the other hand... if you've lost two CPUs on the same motherboard, I'd be looking at that.
 
CPUs are pretty rock solid in my experience. I think you just have a bonified, unlucky conincidence. Especially if you undervolted them, it's not like you had balls to the wall OC settings.
 
If a motherboard killed a CPU, would that be purely down to it being the vessel that delivers the power from a faulty or cheap PSU, or could you have a decent PSU and a faulty motherboard kill a CPU?
I've never heard of CPU's dying bar when majorly overclocked with loads of juice added, I did used to hear the whole "it'll shorten it's lifespan" but I never knew of anyone that had one die in their ownership based on that?

Motherboard VRMs are pretty complex, so they can definitely kill a CPU on their own (heck, the manufacturer just choosing to overvolt at stock can do that), but yeah, a bad PSU can also kill the stuff connected to it.
