Checking standard performance after overclocking with PBO and Curve Optimizer... typical outcomes.
Checking standard performance after overclocking with PBO and Curve Optimizer... typical outcomes.
MSI B550 Unify is running BIOS E7D113AMS.132 from June 28, 2021. It's cooled with a DH-D15 2x32 GB Crucial DDR4 3600 MHz overclocking setup. Advanced CPU tuning is enabled with PBO settings, manual PPT at 142, TDC at 95, EDC at 140. Curve optimizer is set to all cores with a magnitude of -20 (negative values caused errors). Other parameters auto-adjusted. Scores from Cinebench R23 averaged 22,223 and 22,339. Maximum temperatures reached around 64°C with an average effective speed of about 4,400 MHz. No overclocking achieved; results were similar to non-overclocked performance. I haven't tested boost yet. Seeking adjustments to PPT, EDC, and TDC values.
I maintained the same curve pattern (-20 all cores) and increased PPT, TDC, and EDC settings. Updated values: PPT 190, TDC 135, EDC 175. Cinebench R23 (3 min) achieved a score of 22,926 and 22,960. The performance reached roughly 78°C peak temperature with an average of about 4,450 MHz effective. This represents approximately a 6% improvement. Is this typical?
I turn on PBO, select advanced settings, then navigate to the curve optimizer. My adjustments bring me back to the main PBO menu and I disable PBO again. CO settings stay enabled. Update: I just completed the test. The interface works smoothly initially, but at higher speeds (1800FCLK and above) between CCX1 and 2, temperatures can jump up to 12°C each side as the FCLK changes, impacting core temps. It's not the most demanding load, but it can get quite intense at times.
