My system specs are:
AsRock X570 Taichi
Ryzen 9 3900X
64 GB 3200 MHz RAM
Radeon RX 5500XT
AIO 3600mm Cooler Master with 6 fan push pull configuration
I have been overclocking this processor but I am not sure what are the safe limits as far as voltage and temperature go as I cannot find a definitive answer anywhere. My highest clock was at 4.4 GHz at 1.4375 V with max load temperatures never exceeding 76 C. This resulted in a Cinebench score in the 7400s. I am not sure if such a high voltage is safe as AMD recommends not going above 1.35 V. I also have seen that the voltage doesn't matter as long as the temperatures are good and the system is stable.
This is on a workstation machine so it will be under heavy load for many days at a time and I do not want to fry the CPU in only a few years. I dialed back the overclock to Auto settings but put a SOC offset of -0.2 V and a CPU core offset of -0.1 V and I am letting the precision boost drive do the clocking for me. I also set the PBO be from the motherboard. Unfortunately, it limits all my core clocks to 4.05 GHz under heavy load and I am now getting a Cinebench score in the 6700s.
Does anyone have any pointers, suggestions, or insight on this? I am trying to get great performance under heavy load and also have this CPU last.
Temperature is the paramount factor, though it really should be under 1.4v...Check out Clocktuner For Ryzen and see what it comes up with.
