Hey guys,
Just thought I would share my experience with the 14900k as all I really see on here is people worrying about degradation.
I have an SP 101 chip (P 111 E 83 MC 85) for context on an apex encore.
Back in Dec 2023 when I first powered on my PC and was greeted by the bios the first thing I noticed is that my chip required 1.49v to do 6ghz on its two preferred cores and had unlimited power settings set by Asus' default options namely "multicore enhancement".
This spelt disaster so naturally turned off "multicore enhancement" to enforce intels PL1 / PL2 / ICCMAX (but keeping CEP disabled) limits. I set the P-Core ratio to "sync all cores" @ 57x which immediately dropped the required voltage to 1.37v (with XMP enabled) without an undervolt.
Syncing all cores on an asus board auto turns off TVB and having CEP disabled is fine in my books as I prefer to see instability issues / app crashes when undervolting as opposed to frequency throttling.
I increased the load line to LLC6 to reduce the cpu's droop (as the default was LLC4 which had to much vdroop for the 14900k and caused stability issues). I then started undervolting using an adaptive global offset and found a sweet spot at 0.130mv where I found my undervolt pretty much capped out.
I have been pretty much running the vcore at 1.24v since then (57xP / 44xE / 45xRing)
I am currently running the first released raptor lake microcode (11f – originally for the 13900k) on a custom bios (9905) based on the official 1102 bios for the board (pre intel guideline) as it is the most stable for my RAM oc.
This post is really just to share that if you run sensible voltages on your CPU you won't experience any problems.
Hopefully this helps someone 🙂
