Degrading stability 14900K

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.
