14900K why i am not stable at 4096W

xxx123 · May 9, 2024

Hi.
I have 14900K stock with NZXT kraken elite 360, 2x16GB DDR5 6800,rtx 4090,Seasonic Px 1600,SSD 2TB,Aorus Z790 Elite X.

So in AUTO bios config i had crashes when preparing shaders in Lords of The Fallen or Remnant 2 OUT OF VIDEO MEMORY. Clock cpu was 5700mhz.

But after changing power limits P1 P2 253 and Core Limit 400 , i am finally stable , at least for this moment.

But question.Why i am not stable at 4096 ( AUTO ) ?

Someone said this to me:"Just finished this game last week, I am on a 13900KS on 5.9Ghz (Direct Die cooled, PL1 and PL2 are untouched so their 4096, though I am seeing 310w tops from HWINFO) and never had issues with the shader compilation nor with game loading.."

So he was stable on AUTO settings , during shader compilations, then. Why me not?

Have you not heard of all the issues with 13th and 14th Gen motherboards and default bios settings?

bobkn · May 9, 2024

Did you ever monitor what power level the 14900K was running when it became unstable? (Hwinfo would do it.)

Also, direct die cooling (delidding) is better than what you appear to have.

Intel i9-14900K set at 4096W by default!

Anyone running a newer intel CPU should go read this article. I was seeing instant temperature spikes to 100c on the cpu whenever starting a demanding game. I was actually working on something else when I stumbled across this article. The bios gui shown is the exact same one I have. The power...

Because not all chips are created equal.

Just set the maximum CPU core temperature to a reasonable level - I set 85C. The performance hit by throttling is minimal and I only see it running Cinebench.

The CPU will get less reliable and require more voltage as it gets hotter, as it will at higher power. In addition, as power increases so does current, so the load lines (voltage vs current) might not supply enough voltage for the current. There are also other limits that may kick in when you go past 256W and, IME, can sometimes destabilize the processor when it suddenly throttles. So it can be heat, not enough voltage/loadline, or throttling because of the additional power. Those are the usual suspects. But Intel is investigating this issue.

Also, auto BIOS is not stock on many motherboards intended for enthusiasts. The board maker applies voltages, power and current loads well beyond the Intel processor's spec. When you are using a liit of 4096W, you are operating out of Intel spec for the processor, which they recommend PL1 = 125W, PL2 = 253W and 307A for the current limit. Stability beyond those values depends on a lot of factors and settings (overclocking), including the quality of the specific instance of the processor.

Can i try LCCMAX 400A on my 14900K?

Second question.

Package Power Limit 1 = 253 Package Power Limit 2 = 253 Core Current Limit = 307

5.2-5.3Ghz during Lords of the fallen. Is this normal that lower clock?

PerpetualCycle · May 10, 2024

You can try it of course. I would do what @Steve C suggested and set the temperature limit to 85c. That works well. I do the same.

It must be hitting one of the limits and throttling by lowering frequency.

kciN · May 11, 2024

Depends on the load. There is no way these cpus will run all cores @ 5.7-5.9ghz @ 300w. You need to hit the cpu powerball for that. I also have an unstable system at default settings and traced it to Load-Line Calibration and/or SVID defaults. I had to drop LLC to 3 (from 4). It's very weird cause I've always had to go up. Also note that SVID is tied to LLC. So I basically accomplished the same thing by manually setting LLC to 3 or by setting SVID to Typical.

@xxx123 Mb manufactures do not stick to Intel specs on bios defaults, some people can run their cpu's in auto mode and get away with it without any problems but I doubt that their CPU will last very long. If you are stable at 400, 253 for P1 and P2 then stay with that, it will save you a load of trouble in the future. 4096 (auto) is just not acceptable as Intel's figures for the 13900 is 280 amps and 14900 is max 400 amps. All this depends on the guilty of the CPU silicon. Intel and MB manufactures have screwed up big time on this one. Intel's latest batch of gen 13 and 14 are on a knifes edge for for performance, just marketing hype to out do AMD.

Ok finally all issues resolved :) :) Thanks to you guys. So i installed 3 times different gpu drivers. And launched Remnant 2 and Lords of The Fallen. During first shader compilations no crash and no wheas.
Here are my settings:
P1 253W , P2 253W , Core Limit 400A
Load Line Calibration HIGH.

all stable, but pc was loud and there was high temps during shaders.

My i9 14900KF seems to be damaged. Using Asus default settings since day 1, and now the pc is extremely unstable. Tried all the fixes posted here and online. Reset BIOS, install latest BIOS and still issues. Oddly, the PC seems a bit better after limiting the P cores to 57, and leaving the voltage settings to the odd ASUS values of 4096 etc. if I limit then to P1:253, P2:253, Core Limit to 400A, system will work but still give access violation errors in edge and occasionally crash the entire system. I have even tried under volting and this will also work for a while and then become unstable.

This is the first new PC I have built in 15 years, and it's been an absolute disaster. My old i7 990x worked with no issues for so many years, overclocked as well on air cooling . This i9 iwater cooleded, and not worth the effort. The shop I purchased the components from is not interested in replacing, my last effort to getting this resolved is talking to Intel directly.

Madness that the user is stuck with these issues.

Perhaps a memory stability issue or PSU issue supplying the GPU under load?

Try setting Asus multicore enhancement to “enforce all limits” and SVID behavior to “Intel’s fail safe” then work from there. This should give you a workable system and Intel’s defaults.

Newest BIOS have a single setting for this.

Hi, I have used those, and it will remain relatively stable for a day and then go pear shaped again. Extremely frustrating, never expected to have so many issues with top end components.

I rese tthe BIOS to defaults, saved, rebooted, then went back, set the Intel Defaults (new setting in bios version 2202, saved rebooted, and immediate BSOD. Something's seriously wrong with my cpu. I have tested the RAM all passes, reinstalled Windows on a new SSD, same issues. I managed to get it a bit more stable late last night setting all voltages to auto, so it now uses the 4096 setting and in minimal testing it seems "stable"

If you RMA the cpu with Intel, anyone know the process they follow? Do you have to send through your current cpu and they test and send a new one, or do they send a new one, and you post the existing back once received?
