Crash during shader compile on 14900K

[das3erawsdas]

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

So.
Today i launched Lords of The Fallen and during shader compiling it crashed with WHEA LOGGER in event. Should i worry? Otherwise all is stable. Cinebench,games etc.Only in shaders first time compile. Screen: Internal Parity Error

Like you see it throws WHEA during shader compile on first time.
Is my cpu ok?

Is this in-game or by running a synthetic benchmark? Games utilize your system differently than a benchmark, which can make certain workloads and frequencies variable. If by increasing the currents to 400A also increased your multi-core frequency then logically you were previously limited by that. The frequency can lower when there's more cores being used at a high core clock ratio to adhere to the power profiles, or when another component is throttling. Intel processors doesn't really boost all the cores to its max, at least not within Intel's own specifications. Some boards will use features like MCE to try and bypass that issue which also disables any power limits of the CPU in the process.

Your 14900K has a max turbo frequency of 5.6 GHz on the P-cores, anything above that is done by Intel Turbo Boost (single-core) and Turbo Boost Max 3.0 (core-detection), which is entirely reliant on the thermal and power headroom of your CPU, aswell as how the program is utilizing your processor. Just leave it at 253W on PL1 and PL2, and 400A for the moment. The frequency is fine. Once your board vendor releases a new BIOS update for the Intel default settings, update to that and don't worry more about this issue.

Yes i will leave it 253W on PL and PL2 and 400A. Clock is 5677mhz.

But when i was on 253 PL and PL 2 and 307A, clock was fluctuating between 5270mhz-5370mhz in Lords of The Fallen. It was normal or too low clock?

[Rune]

5.4 Ghz is quite normal on 307A on a 14900K, depending on the workload.

[das3erawsdas]

ah ok thx so its basically downclock?

[Rune]

No, downlocking means you're changing the core clock ratio multiplier down. Power limits just means that your CPU can't go above that power target. You can still get 5,6 Ghz and above as long as it's not on all cores, it depends on the game you're playing.

[das3erawsdas]

oki. So leave it 253W on PL and PL2 and 400A?

[Rune]

if the game can use most of your cores, then yes that would be normal. And yes just leave it at 253W PL1 and PL2 and 400A, that's within Intel specs.

I find on reddit. Someone with P1 P2 253 and 307A. 14900K

P Cores are topping out at 5.7Ghz desktop, and 5.0-5.3Ghz gaming.
Why such lower clocks with 307A?

That's just what ICCMAX does, it can lower your frequency because of the currents limit. 307A is technically "safer", but 400A is still within Intel specs and will retain higher clock frequencies, as you've noticed. I'm not an Intel engineer so I can't tell you exactly why or how the CPU works, but that's just what it does.

ok thx bro you really helped me

I have an last question. 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 why he have not issues on auto? 4096

Not everybody has these stability issues on these K SKUs due to what is coloquially known as "silicon lottery", there's a specific operational range to all silicon based chips so the actual spec is the most conservative setup so all these parts will hit it.
Meaning some are better than others, some reach higher clocks with lower voltage, some need more voltage for the default clocks, etc.

It's the reason why "KS" SKUs exist, they are but better binned parts sold at substantial markup to those who think it's actually meant for gaming.

Case in point is Buildzoid's (from Actually Hardcore Overclocking channel) hours worth of rambling as his specific CPU is not stable in Cinebench R15 on motherboard defaults (i.e. OC from factory), but it is perfectly stable at intel default spec.

I recommend to use Intel XTU Tool so you can change everything on the fly (for testing).

BTW: i undervolt my cpu and CB23 runs perfect but LOTF crashs during shader comp.
so i set my undervolting two steps higher andthe game runs.

Here is a picture from Intel how to setup the cpu's (scroll down a bit):

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.
