Hello, to make it easy to read, I'll try my best to answer to all your points in their order.
- The temp spike lasts while the usage is at 100%, so if for example a render is taking 10 seconds, it'll last 10 seconds with that high temp, everytime I run a Cinebench it lasts the whole duration of the test, and when I render on Blender using cycles it stays above 90°C while rendering.
- Sure, here you go, here's a screenshot of Core Temp while the CPU is idle and when it's under 100% load, after formatting I currently don't have XTU installed, but I can provide a screenshot of it later:
idle temps
100% load temps
- The motherboard is an ASUS PRIME H670-PLUS D4, but in the future I wanna upgrade to DDR5 with this same CPU
- Ehhh I had like an endless amount of issues with the previous CPU (AMD Ryzen Threadripper 1950X), 4 years of random freezing, it would freeze with C-States enabled, it would freeze if I overclocked it even tho AMD advertised it as an "overclockable" CPU, it would randomly freeze for no reason while I was streaming on Twitch or even just playing with my friends on Discord, then in the last period, before it finally died, it used to take like over 30 minutes before the PC would even POST, it always had less than half the FPS than even an i7-10700F could produce, comparing it side by side with a friend, random blue and green screens of death, then one night it completely died, giving error "0d" on the motherboard, which neither me or my friends ever figured out what it meant... and then I ordered this i9-12900KS and finally switched back to Intel forever, after all, besides the extreme temps, this i9 hasn't frozen even once or ever given me a single bsod since I got it, it's basically perfect!
- I'd like to overclock it, but I ain't been able to do so yet due to these temperatures on stock voltage, I also tried to downvolt it a bit, but not much changed... also, yes, I'm using XMP for the memory, if that could be useful.
- As I said before, this CPU is rock solid, hasn't given me a single green or blue screen of death yet (and I really hope it stays like that)
- I'm getting these temperatures only when the CPU is rendering or it's being used at 100% (for example if I make a VM and assign all 16 cores to it, which obviously I wouldn't do). When it's idling or under "normal usage", it seems to be staying in a range between 38 and 75 degrees, with the average of 41-45 (I monitor it the whole time, keeping Core Temp's tray icons in the taskbar)
I hope this can satisfy your questions, I'll install XTU and provide a screenshot of it (which is where I see the EDP throttling) as soon as I'll be able to, thank you!
