Intel Core i7-14700KF problem unreal engine

[InsProject]

Hello Intel Support Team,

I am experiencing severe instability issues with my Intel Core i7-14700KF processor.
I have tested CPU, RAM, PSU, GPU and cooling, but the problems persist across multiple games and stress tests.
The system crashes and shows errors that are consistent with the known 13th/14th Gen Intel instability issue related to Oodle decompression and Unreal Engine games.

Below I provide detailed information, logs, and screenshots.

System Specifications
CPU: Intel Core i7-14700KF 3.4GHz (Turbo 5.6GHz), 20 cores / 28 threads
GPU: NVIDIA RTX 4080 16GB (Gigabyte Eagle)
RAM: 64GB DDR5 (2x32GB) 6000MHz G.Skill Trident Z5 RGB
Motherboard: Gigabyte Z790 UD AX
PSU: be quiet! Pure Power 12 M, 850W
Cooling: DeepCool LE720 AIO (360mm)
Case: Lian Li O11 Dynamic EVO
OS: Windows 11 x64

Description of Problems
- Games crash after 3–5 minutes with no error or with exceptions (e.g. 0xc0000005).
- Unreal Engine-based games show:
DecompressShader(): Could not decompress shader (GetShaderCompressionFormat=Oodle)
- Event Viewer logs show application crashes with 'unknown' module or nvspucomp64.dll.
- Sometimes Windows logs report: "Out of video memory" errors, but GPU is fine.

-Clair Obscur: Expedition 33 & Throne and Liberty & STALKER 2
After buying my PC, I was able to play Clair Obscur: Expedition 33 without any problems for about two months. Then I took a break, and when I tried to launch it again, I got the error shown in the screenshot.

Now I have the same problem in Throne and Liberty and STALKER 2 – the game crashes shortly after launch.
What I’ve already tried to fix it:

-Reinstalled GPU drivers (clean install, latest version)
-Fully uninstalled and reinstalled the game
-Launched the game with -dx12 argument
-Verified games files
-Updated Windows and all other system driversStress tests:
- OCCT (CPU+RAM) sometimes fails.
- Separate CPU and RAM tests usually pass.
- Power and GPU tests pass.
- BIOS: Many settings were on "Auto", which appears to apply hidden overclocking (Enhanced Multi-Core / Turbo settings).
- Temperatures: CPU can spike above 90°C in OCCT within seconds, despite AIO cooling. Pump speed ~4500 RPM (normal).

Known Intel Issue Reference
I am aware of Intel’s confirmed issue regarding 13th and 14th Gen Core processors (rapid aging of clock circuitry, Oodle decompression crashes, system instability).
Symptoms in my case exactly match the descriptions from Intel advisories and developer reports (Unreal/Oodle crashes, benchmark instability, 0xc0000005 exceptions, etc.).

...hey dude

all the signs are pointing straight at that 13th/14th Gen Intel issue. You’re getting the same stuff everybody else has been reporting, Unreal Engine and Oodle decompression errors, random crashes, OCCT tripping out, temps shooting past 90°C even on a solid cooler… it’s the exact instability pattern. At this point, it ain’t your RAM, SSD, GPU, or PSU, you already swapped and tested those. It’s the chip. That CPU’s cooked, no two ways about it. Intel already admitted some of these 13th/14th Gen processors got that instability problem baked in, so your i7-14700KF is most likely one of the unlucky ones. What you gotta do now is hit up Intel’s site and open a warranty ticket replacement, That’ll get you a replacement chip. I’m telling you, man, this one in your rig is faulty, no amount of reinstalling or tweaking BIOS is gonna save it. Warranty is the move.

...hope it helps,
