Overclocking
The only way to overclock the 7000X3D CPUs is through the curve optimizer by enabling the Precision Boost Overdrive (PBO) through the BIOS or Ryzen Master. Because of the pair of different CCX in the 7950X and 7900X, manual overclocking is not available anymore. This means that you cannot set specific clocks and multipliers. For those unaware of what the curve optimizer does, it allows you to set the operating voltage of each core independently. Precision Boost Overdrive (PBO) allows the processor to run beyond the defined voltage values to the board’s limits and boost at higher voltages for longer durations than the default.
I initially set the curve optimizer at -30 for all cores, and I had instability issues by increasing the frequency to +200, so I had to lower the CO setting to -15, where everything went fine. As you will see in the following graphs, the overall gaming performance is similar, while the applications’ overall performance gets a small boost, lower than 2%. I suggest you try to set optimally the CO, to increase the CPU’s efficiency.
