AMD’s Precision Boost 2 algorithm maintains lofty light-threaded boost clocks, so keeping this dynamic clock control active continues to be my favoured way to overclock AMD processors.
Using Curve Optimiser worked well and delivered an almost 200MHz boost to the all-core operating frequency for our Ryzen 9 7900X.
CCD0 clocked in at 5.35GHz under load, and CCD1 measured as 5.2GHz. This speed boost was all while the power draw and temperature remained tolerable… by Ryzen 7000 standards.
Manual Overclocking Power and temps
There’s also the 88W PPT Eco Mode that can be easily applied through AMD’s Ryzen Master software. This cut clock speeds to around 4.35GHz on CCD0 and 4.175GHz on CCD1. And, of course, temperature levels were also drastically reduced.
If you prefer a more in-between running mode, you can manually tune for a 105W TDP or 142W PPT as we did. This delivered a clock speed of around 5GHz on CCD0 and 4.8GHz on CCD1. Temperatures were also still very tolerable at sub-70C under load.
Manual overclocking performance
Overclocking via Curve Optimiser is a very sensible way to run AMD’s Ryzen 9 7900X. You basically get a free performance uplift for no extra power consumption, and temperatures of 91C are still fine.
The 142W PPT Eco Mode is very strong, too, with a reasonably small percentage of performance shed in favour of better efficiency. You also get the one-click 88W PPT Eco Mode via Ryzen Master which could be useful to SFF users with cooling constraints.
Curve Optimiser overclocked is my preference here, particularly when it helps the Ryzen 9 7900X just about fend off the high-powered Intel Core i7-13700K.
