I9-14900K Voltages question.

[⸸𝙿𝚛𝚊𝚡𝚒𝚜⸸]

If anyone here has had this CPU for a while, Id greatly appreciate the help.

So Ive gone from an i5-8600k, bought at release, @5ghz constant clock, 4.6ghz cache clock, 1.45-1.48v.
To an I9-14900k build earlier this week and Im getting my head around the jump in gens for OCing.

I am aware of the voltage crisis associated with these cpus, but, bought it anyways lol
Even with the new micro code, latest bios for the MSI MEG ACE, it was still hitting 1.59v+ according to HWinfo.
I currently have it set in the following to avoid spikes of 1.5v and further.

P-cores. 5.7ghz, constant clock, all cores. -100mv on all p-cores.
E-cores. 4.6ghz, constant clock, all cores. no undervolt on E-cores.
Max package temp of 63c.
Stable.

My Core VIDS min-max-average is as follows.
Minimum - 1.177v
maximum - 1.5v
Average - 1.359v

These values are after about 30-40 mins of letting Stalker2 sit stationary in a busy area, at max settings, 1080p, average 98fps.
Figured real world load instead of benchmarks would provide the real use values.

So for a constant clock set of 5.7ghz, maybe 5.8 on P-cores and 4.6 on e-cores, these voltage values shouldnt cause the degradation known to affect these gens, yeah?

Am I right in this logic?
I was reading that intel said 1.72v is the max safe, but ♥♥♥♥♥♥♥♥♥ that lol.

EDIT: is there any other practices other than turning intel's clock/voltage control off and doing what Ive already done to make sure it doesnt damage itself?

In my opinion anything under 1.45 is fine. Intel went mad with 13th and 14th gen CPUs. Chip sized of a matchbox can pull 400 Amps, that said chip's TJmax value is 100c and Intel says it can run safely on 1.72 Volts. Basically this chip is a fancy 320W heater.

No wonder people killed their chips.

I use the following on my 14900k, note this is technically an undervolt, not an OC. But the results I've got are better than intel/msi's presets.

* Core Lock - P Cores: 5.6
* Core Lock - E Cores: 4.1
* Negative 0.055v CPU Offset
* Power Limit 250
* ICCMax 307a
* CPU Current Limit 307a
* GT Current Limit 30
* ICCmax Unlimited Bit Disable
* CEP Enable
* EVTB Enable
* TJMax offset 0
* AVX Offset -2
* Intel Speed Shift Enabled
* Intel Turbo Boost Max 3 Disabled
* Enhanced Turbo disabled
* VR Voltage Limit 1.450
* CPU VR Voltage 1.450
* BCLK 100mhz Lock - On
* CPU Switching Freq - 500khz
* CPU Loadline Calibration Mode 6
* MSI Lite Load 9

This keeps the voltages at 1.35v, temps were max 90c on the P cores in a 30c ambient (yes, that's 30c since I'm in summer in Australia) and 80c on the E cores. Power usage rarely goes above 230w. If it's unstable, wind back the voltage offset by 0.005v at a time (eg go from minus 0.055v to 0.050v), and try putting the MSI Lite Load up by 1 (ie, from 9 to 10).

I use thermal grizzly phasechange as the CPU thermal interface with a 360mm AIO.

I still get a cinebench R23 score of 39k.

Ayee, good to see you again lmao, you get that DeadSpace stutter sorted?

Good info, appreciate it, Ive managed to get it to sit at a max of 1.472v under load with the same constant p/e-cores.
So Im happy. Im okay with the occasion jump to 1.5v, my I5 was hitting that daily for like 5 years so Im sure this one will be fine, especially with the "1.72 safe voltage".

Its definitely not a chip for the average consumer thats for sure. Essentially the XMP profiles that come with the boards are guarantee degradation, it seems. I mean If I hadnt checked HWinfo and trusted the latest bios to fix this issue, it would be bouncing near that 1.72v all the time to get 6ghz in super quick bursts, which is.. not cool lol.

I know what you mean lol.
Its incredible watching the CPU pull over 50w more than my entire i5 platform pulled under stress lmao.

Thanks for the options list, super valuable.
Theres so many more options than the 8th gen I need to learn about, so this is a great place to start.
The bios for this board has so much stuff I just look at some of em like "coooooool, dont know what any of that means but... cooool" lol

My goal is to get it to sit at or near 6ghz constantly while hitting acceptable voltage maximums.
So again, appreciate the details of your config, I'll have to research what some of those options affect before I start mixing them in with my current config.

Hello Praxis! I was positively surprised when I saw you here as well. o/

Meh, it stutters like a.. thing that stutters, but it's OK. It's one and the only game in my ~250 game library that acts like that. And I've already played it through couple times while trying to fix it.

I don't think quick bursts to 1.5 volts is going to fry your CPU. I'm keeping my i7 13700K limited to 1.35 volts and of course undervolted. But instead of boosting up to 5.6-5.8ghz it only goes to 5.3-5.4ghz (Intel's default) depending on cores. This way I'm keeping my temps waaaay below TJMax and I don't get significant performance hit in the process (practically no performance hit at all).

When I built this setup I was shocked when I saw the values Asus/Intel thought would be OK. And then there was this whole degradation fiasco but from the day 1 I undervolted my CPU and kept reasonable power/current limits (Intel's default) instead of Asus's 4096 Watts/511 Amps (sic!). After the microcode updates this chip seems to run on lower voltages than before. To be more precise it doesn't shoot up to skies/plummet so low it causes crashes in burst loads and load releases - which apparently caused problems for users who didn't set proper power/current/voltage limits and let their chip roam free before the microcode updates.

Times oh are they changing.. My CPU sucks ~250 watts at worst and my GPU is thirsty for 300+ watts in under heavy load. First time in history as a PC owner I'm noticing this in my electricity bill. Crazy times indeed.

Good luck to your new build! 14900K is one sick CPU when set up correctly! It rips through multithreaded and/or heavy workloads. A solid choice for a user who does more than just plays games on their PC.
