Fixed it you're good lol, but far as Intel I've heard conflicting things about what's even impacted. Some seem to indicated it's just 13900K/14900K while others seems to indicate it might be the entire raptor lake/refresh series could be impacted. Like it doesn't sound like it is necessarily strictly just a TVB issue with the highest end model. Who knows though honestly. I'm presuming you use a anti-intel-failing bracket? I think that could be creating issues where it's hard to pin point the actual root problem definitively as easily. I do believe L1 Tech is on to something with trying to narrow down possible evidence pointing to a particular fault or problem. It seemed like the IMC was suspect in part of what he found looking at like crash reports. I'm pretty sure your CPU is undead. It's alive, but is it really living.
What's the SP on that chip btw!?
I think there was a case that was legit and now all Raptor Lake CPUs are toast!! HAHA! Who's to know, but I haven't seen a dead one and I hang with a few guys that LN2 13/14900K/KS/KF chips quite frequently.
My thought is the e-core complex isn't exactly stable or the power draw while on heavy loads causes issues. Of some kind or another. Generally CPUs have a failure rate, but they aim for that of less than 2% released in the wild while AMD 3000 series chips suffered failure rates recorded as high as 5%..... So take that for w/e it's worth?? lol.
Nope, no bracket. I just thumb snug, not tight. The density is so great, it doesn't matter that greatly as people would suggest. From what I can experience, Intel likes v-core and cold. But requires both.
SP remains unknown. Asus B660-G I have, doesn't give SP numbers. MSI doesn't cater this feature. Core #4 is my fast one (fifth counting from 0). E-cores are fairly stable at 4.7ghz. P-Cores seem very average. Have no issues hammering in 5.2ghz Cache speeds. I could definitely use a better kit of RAM, but I can pull of 7200mhz with CL 36-36-36 Samsung chips, so that's fair I suppose. Not stable for daily, but can run some benching.
What you doing at−78.5 °C?
I'm sorry I didn't directly answer you yet. I'm finally ass down in an office chair....
I do stuff like this with Dry Ice.
6.4Ghz 16 threads, No E-cores @ about 275w
See the V-core needed to keep effective clocks as high as requested clocks?
Additional Comment:
I'd like to say this is a 200$ motherboard. Average Joe stuff. This is no Apex. I don't throw my money out like that. GPU costs kill those adventures. LN2 in my area is like 100$ for 10 Litre. This is the reason I don't use LN2. I have a 22 Litre dewar, the last time I used LN2 was to install cylinder liners into a Perkins small diesel engine. So at least when I have these kinds of jobs, if there's a little left over I can at least get a little colder.
