Degrading stability 14900K

[underclocked14900k]

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

Have tried everything. Random crashes in games- unreal engine games specially. Bluescreens, you name it.
