Did adjusting the voltage settings beyond -50 on the Curve Optimizer affect your performance?
Did adjusting the voltage settings beyond -50 on the Curve Optimizer affect your performance?
I applied Ryzen Master to set the Curve Optimizer to -50 on my Ryzen CPU. I'm checking if this level is too aggressive and might lead to instability. I also wonder if pushing it higher could improve performance. Have others experienced this setting or found a stable optimal range?
Typically, users achieve an -30 offset, with some opting to keep it at -25 for extended situations. It’s advisable to perform a stress test on your undervolt settings to ensure stability. Consider documenting your build details such as CPU, CPU cooler, motherboard, RAM, SSD/HDD, GPU, PSU, chassis, OS, monitor, and include the age of the PSU along with its make and model. Also note the current BIOS version for your motherboard.
yes i too saw -30 max! but my mobo lets me go to like -255 ! that's strange right? still i will stress test this in games and also prime95 and those apps.
Until testing is done, it's hard to determine. It really does rely on the "Silicon lottery," though. My 7900x works well at -25°C, but I stick to 20 because I have a bit of room for error in Tjmax. So nothing extra is necessary. With a non-7700 and a cooler like this, you shouldn't need any CO if it stays below 80°C during full, long use. I've seen 7700x running under a 360 AIO cooler with an extra 30 CO, which boosts the boost frequency by about 200-300MHz.
CO's meant to change core voltage dynamically, and the negative setting aids cooling to keep temperatures below Tjmax. Any temperature lower than that isn't helping performance much.
PS. Avoid using RM or other settings—just go straight to BIOS. 100% reliable for me.
For more precise control, you can tweak CO per core instead of per CCD module, since not all cores behave the same.
check if the system is working properly after optimization, because getting -255 for all cores seems unusual.
Don't use Ryzen Master for that. It's unclear what it does to your CPU and what could happen if something goes wrong. Optimize your curve settings directly in the BIOS, so you're certain of what's happening. I adjusted mine (9800x3d) to -15 and it's sufficient to keep it well below throttling. Adding a +100 MHz in PBO still keeps temperatures reasonable.
