Degrading stability 14900K

underclocked14900k — Mon, 15 Apr 2024 18:50:09 GMT

After owning an i9-14900K for a month I have observed the following:

Initial performance tested as stable with Intel-approved Turbo-boost settings and power limits provided two P-cores at 61x ratio
Validated stability with 3dMark and MSI Kombuster
Observed high packager temps (95C~85C) than typical with prior CPU gens, but core temps never exceeded 80C
CPU averages ~45C during typical loads (gaming)
After two weeks, PC stability plummeted without change to prior working settings
CRC errors, Blue-Screens, System Restarts all observed with system uptime never exceeding 60 minutes

To troubleshoot system stability, the following was performed:
- Full OS refresh
- Memory Hardware Testing
- Validated performance of CPU cooling solution
- Validated voltages supplied by motherboard
- BIOS Update
- CMOS Reset
- Reset Motherboard to Optimized defaults
- Increased line voltage stability to core
- Disabled Intel Boost Technology

Resolution required locking P-core ratios to 57x (+1 for one core) and E-core ratios to 44x

System now tests stable with a loss of ~5% performance of advertised specifications.

I'm looking for any resolution to obtain stability at advertised performance levels for this CPU.

I have the exact same problem as you.
Done exactly the same steps as you.
My setup;
i9 14900k
Asus rtx 4090
Asus z790 apex encore
Gskill 7800 ddr5 32gb
Have tried everything. Random crashes in games- unreal engine games specially. Bluescreens, you name it.
