Currently running a 14900KS on asrock mobo, all cores locked at 5.9 with adaptive voltage and a -100 offset in fivr/llc set to level 3, with ac at .63/ dc at .74, and its stable around 1.35 voltage/vids, ring also set at 5.0 min/max,. My only issue is in games i get IA: Electrical Design Point/Other (ICCmax,PL4,SVID,DDR RAPL) in hwinfo at times and the cores downclock to 5.8ish at times, unless i set a crazy 1.60ish VR voltage limit. Is this safe? I'm on an asrock motherboard and i have no way to see actual transient spikes or voltages my cpu is getting. But my vcore/vid they never go above 1.37ish. Is it actually possible transient spikes are spiking up to 1.55 and its throttling me unless i set to 1.60? Or is it simply the the request that is throttling me. Sorry, i'm new to this

Hi and welcome.
Your CPU is trying to draw more power than bios has limited it with the settings you've chosen so the CPU throttles .
What are you using your pc for ?
Motherboard bios update to date ?

Yeah its up to date. And its throttling because IA VR Voltage limit i set it to 1.50-1.55. The only way to make it not throttle is if i set it to 1.59-1.60ish. I don't understand why i need to set that so high, especially if my actual vcore/vids are 1.36ish, and never even going above 1.4.
Yeah i've already set the PL on it, its not being throttled by that its being throttled by IA VR voltage limits, which i have to set at a ridiculolus 1.60 or else it will downclock. Trying to understand why that is since my vcore/vid is around 1.36 during games, so it shouldn't need anywhere near that much, and idk why the cpu would even request that
Have you tried reducing the polling period in hwinfo ? Maybe it's a really short spike.
Never touched IA VR limits myself.
Yeah, it throttles no matter the MS i set, even in games i use msi afterburner and i see cores drop very briefly to 5.8 at times. Could this have something to do with my LLC settings? I'm using LLC level 3 (middle on asrock), and ac of .65 and a dc of .74. At 1.55 vr limit they are very short and brief and rare, but still annoying and i don't understand why the cpu would request that especially since my vid/vcore is 1.36

Maybe you have a bad CPU.
Some 13th and 14th gen Intel CPUs have been experiencing instability issues, including crashing and potential permanent damage, due to elevated operating voltages. Intel has identified the root cause as a microcode algorithm that requests incorrect voltages to the processor, leading to instability. While Intel has released microcode updates and other mitigations, some users may still experience issues, and Intel recommends contacting customer support for affected systems.

i don't think so it has an sp score of 110 and can do 5.9 at 1.35, my vids are really good, its just this stupid IA VR voltage limit, i don't get if its actually sending that much voltage via transient spikes that i can't see, or if its just the cpu requesting that much but it never actually comes close to that

So reading your first post again your only issue sometimes you get 5.8ghz in games does this give you big drops in Frames , noticeable dips ,stutters ?

i haven't noticed any big drops or stutters or anything, this is more so just me wanting it not dropping 5.9 at all lol.

6.2 gz on the 14900ks is only achievable on 2 cores and there are a lot of variables which will slightly lower clock speeds such as cooling .
So if your getting 5.9 across all cores that's a good result after reading other threads on Reddit,etc.
well i agree it is a good result if it actually held 5.9 and not drop unless i gave it a 1.58ish vr voltage limit. i've been looking everywhere to find more information on this, intels default spec on it used to be 1.720, but they since lowered it to 1.55, so i'm not sure if 1.58 is safe. Also, not sure how much voltage my cpu is actually getting in transient spikes, if its that high or what since i have no way to detect it
400/unlimited tried both neither did anything. only thing that has ever done anything is raising the ia vr voltage limit. just tried lowering the cores to all 5.8 and it doesn't trigger the IA: Electrical Design Point/Other (ICCmax,PL4,SVID,DDR RAPL) when i do, even at 1.5. it could probably go lower. So 5.9 takes 1.58 while 5.8 takes 1.47-1.50. I wish i knew more how transient spikes worked and these crazy requests.

What game ? Curious to see if I can repeat it myself.
