So, just wanted to post this in case anyone has similar issues and finds this thread, the new mainboard did in fact solve all the instability issues. Furthermore, with PBO enabled the CPU now boosts to its thermal limit again, without any "spiky" performance drops resulting in worse performance...

So I've ordered a new mainboard - Asus rog strix B550-f gaming - any thoughts on that? I've watched a comparison of several B550 mainboards by Hardware Unboxed, it performed really well for its adequate price. It's a little old so they only tested it with an overclocked 3950x, but as it could...

So, something does indeed not seem quite right here. I suppose the vsoc phases are the 2 that are horizontally placed and not under the heat sink (?). The tip with measuring from the rear was really good, because I couldn't see anything from the front because of the cooler fans + heatsink...

No, I think you misunderstood. I cleared the CMOS, ran a few tests, then went into the bios and modified the fan curves, together with the XMP settings. I have previously tested if the RAM was the problem, maybe because of the mix, even though it was working fine before, but it wasn't the issue.

I'll see if I can find one, but keep in mind the Pro4 has a pretty big heatsink across the VRMs so you won't see much there

Yes, I have since the reset applied a "slow" XMP profile again, and adjusted the fan curves.

Did some more prime95 testing, this might be more interesting. I also added all the "current" stats I could find.

Wasn't ticked.

Here are some screenshots: Idle: Cinebench: Prime95 (interestingly, it boosts higher here, yet not to the 90° mark): Here is a selection of graphs (The idle stats are before any CPU load, the first major CPU load is Cinebench, the second, less consistent load is Prime95) (I don't really...

I meant it didn't crash with the 4650g. Which exact values would you like? Do you want a log file? I suppose a single instant isn't really enough. I can also try showing you some specific graphs.

HWInfo64 doesn't know anything more: It says this for all entries except "Motherboard" which just says "Mainboard temparature" and "CPU", which is irrelevant. Mainly though, these values are also not higher than the values from above.

Never mind, crashed again.

(Pink is the CPU, red the mainboard sensor, whereever that is)

This is the current throttling behavior:

Do you think it could just be "bad silicon"? If so, what should I do? The way it currently is really isn't usable. I can use it for testing and for some minor work, but it crashes even on not so extreme loads, an hour ago even just from running Firefox and some monitoring tools.
