From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yeah I'm on my 2nd motherboard due to the first having issues where it just plain wouldn't post 75% of the time, and this 7700x is just.... sporadically unreliable.
It won't fail ANY kind of stress test I throw at it, but will then have notepad crashing repeatedly. I'm confused because it makes SO no sense and tired of dealing with it and it's on it's way to replacement as soon as there's benchmarks out for the Core Ultra stuff, and whatever Tim Apple does with the M4 Macs.
(Not really asking for diagnostic advice, as I've spent most of the last year diagnosing and replacing pieces and not being able to firmly blame the CPU or the PSU or the Motherboard or whatever since the failures are sporadic, and what doesn't work seems to change occasionally.)
Maybe you have just ended up with a lemon CPU. Though for random crashes like that, I'd almost always look to RAM first.
I did have some stability issues early on when trying to enable Expo. Never quite got that working right so it is currently disabled. I keep my 7600x in Eco mode since it is air cooled and the performance difference is not that great anyway, so I haven't noticed any major differences with Expo off.
The Expo issues were also with a very early MSI BIOS. I haven't tried it again after upgrading, but I probably should.
Yeah the goofy thing is it pass any length of memtest I care to toss at it, and will happily run prime95 forever with zero issues.
And then immediately have apps crash or freeze or otherwise misbehave.
Like, something is wrong, but nothing is actively broken, which is just.... annoying, heh.
The MSI board has been a source of less than enjoyable usage, but it's almost exclusively tied to the super super long POST times and the fact that, sometimes, it just... doesn't. Hard to know if the 90+ second wait is the normal 90 second wait, or if it's actually not going to turn on for some reason.
It's fine other that little quirk, at least as far as I can tell.
It volts up under load, maybe the problem is too little voltage at light loads.
Well, shit. This may have led me down a useful path.
So not voltage exactly, but load line calibration adjustments looks like it very much MAY have resolved the issue.
Or at least, I've been whacking at it with all the workloads that were unstable and crashing and so far it hasn't misbehaved at all.
