Overview

  • Original issue solved: Temperature problem with AIIO installation.
  • New issue encountered: Power limits affecting performance.
  • Objective: Enhance PC performance and lower temperature via undervolting and power limit adjustments.

Key Hardware and Financial Considerations

  • Initial PC Build: $800 gaming PC.
  • After Modifications: Cost increased to $900 due to AIIO installation.
  • Objective: Improve performance without further expenses.

Software and Sponsorship

  • Windows Activation:
    • VIP SCD Key sponsorship offering Windows 10 activation keys under $20 with a discount code: cyber CPU.

Technical Details

  • Testing Process:
    • Use Ryzen Master for adjustments and Cinebench for performance testing.
  • Current Findings:
    • The socket power was limited, causing performance caps.
    • Temperature under control but limited frequency due to power constraints.

Solutions and Techniques

  • Precision Boost Overdrive: Increase power limits safely without damaging the CPU.

    • Main components:
      • PPT (Package Power Tracking): Maximum wattage processor can consume.
      • TDC (Thermal Design Current): Maximum sustained current in amps.
      • EDC (Electrical Design Current): Maximum current for short spikes.
  • Curve Optimizer: Undervolt the processor by manually setting voltage offsets.

Optimizations

  1. Manual Offset Setup:

    • Set Curve Optimizer to a manual offset of -50.
    • Test if undervolting stabilizes system performance.
  2. Performance after Adjustment:

    • Drop in temperature and increase in frequency.
    • More efficient power usage with lower wattage after optimization.

Testing and Results

  • Cinebench Results:
    • Initial settings limited performance.
    • Precision Boost Overdrive alone increased temperature mildly but solved power limitations.
    • After implementing the Curve Optimizer:
      • Notable temperature drop.
      • Increase in average boost clock.
      • Lower power usage compared to stock setup.

Further Considerations

  • Overclocking Settings:
    • Tested Auto Overclock to increase boost by 200 MHz above factory settings.
    • Results in higher, stable boost speeds without excessive temperature increase.

Final Thoughts

  • Manual Testing: Essential for stability across different applications and conditions.
  • Plan: Leaving Curve Optimizer at -50 for better stability and potentially turning off auto overclocking for lower temperatures.
  • Future Steps: Consider individual per core settings if instability arises.
