Posted by streamcore on 3/10/2025 · 45 replies
After weeks of testing, here are my recommended Curve Optimizer settings for the 7800X3D on the ASUS B650-PLUS:
**PBO Settings:**
- PBO: Enabled
- PBO Limits: Motherboard
- Curve Optimizer: Per-Core
- Best cores: -15
- Other cores: -20
- Scalar: 1x (leave this alone)
**Results:**
- Stock: 4.95GHz all-core, 5.05GHz single
- With CO: 5.05GHz all-core, 5.15GHz single
- Temps dropped 3-4C at the same performance level
- Cinebench R23: 16,100 (stock) vs 16,800 (CO tuned)
**Stability testing:** Ran 1 hour of OCCT Small AVX2, 8 hours of y-cruncher, and 48 hours of daily use with no crashes.
**Warning:** Every chip is different. Start at -10 all-core and work your way down. If you get WHEA errors in Event Viewer, back off 5 counts on the offending core.
