I began thinking about it after checking the speeds and voltages, as well as what others achieved. Although I haven’t run cpu-z or prime95 l, I noticed in the mw3 benchmark it reached 4030 mHz with up to 1.43v, but it won’t always hit 4.2GHz. Temperatures were between 50-55°C, and in-game temps averaged around 50°C. Idle temps stayed between 35-37°C. I’m unsure if I should manually overclock it. Currently, I have Ryzen Master set to default, and the game’s boost is off in BIOS. My main concern isn’t boosting FPS, but lowering voltage to reduce heat—something that usually helps. Should I give it a try?

Specs:
- Ryzen 53600
- MSI X570
- Corsair H150i cooler
- 2070 Super
- Corsair HX1000i

If you're concerned about temperatures beginning to rise due to an undervolt via negative core offset (-CO), consider starting with -30 all-core, but be aware that this may not always be feasible (depends on your setup). If stability isn't guaranteed, reduce the offset to -20 or even lower. The higher the offset, the lower the voltage, and stable CPUs can still support better boost clock speeds. Keep in mind, crashes with -CO usually happen during idle periods or when there are sudden spikes. If your PC randomly restarts at startup or when you leave it on, decrease the core offset accordingly.

I experimented with various settings but didn’t succeed. I tried -20 and the system wouldn’t boot, so I had to reset the CMOS and now set it to 1.275 @ 4GHz. It seems stable, so I might try 4.1 or increase to 2.9v. I’m not sure what else I changed before, but I remember setting LLC to auto and seeing core voltage at 2.8V in BIOS, while the CPU core VID was consistently 1.1. With 4GHz @ 1.275, I switched LLC to mode 5 and both readings in HWINFOR now show 1.275. Temperatures are better, achieving 65-66 idle lows in game 43-46. Overall it’s improved, but I’d like to get closer to 4.1 or even 4.2 to maintain performance.
