Agreement on powerplan configurations for Ryzen 5000 processors
Agreement on powerplan configurations for Ryzen 5000 processors
After upgrading to the 5000 series, I mainly updated chipset drivers and noticed my power levels were consistently stuck between 85% and 100%. It seems there was a bug in the 3000 series where idle voltage didn’t drop properly, and that issue was officially fixed by AMD. In newer Ryzen models, what’s the default power setting? Some suggest it’s around 5% to 100%.
Settings for power? They're set the way they were when they arrived.
My 5950X runs at 5%/100% power during idle, which uses less energy than my Xeon E3 1280V3. Compared to my 3900XT, it didn’t consume significantly more at idle, though it was marginally less efficient. I apply PBO in winter and ECO mode in summer with the 5950X for thermal and performance control. In spring, I could switch off ECO and PBO, but once temperatures exceed 70°, I activate ECO to maintain optimal temps.
There appears to be an ECO setting, though my CPU doesn't seem to support it properly. It looks like the default is around 5% or 100%. After using it at 85% and 100%, I haven’t noticed any changes yet. This chip uses significantly lower voltages compared to my 3600, which might be why it feels more efficient. Edit: AMD powerplan seems to be the ECO option, but it’s not available right now. I’ve usually relied on the Windows balanced power plan for optimal performance.
ECO mode is included within PBO, but you need to turn on PBO first to unlock ECO. The 5800X3D doesn’t support PBO, which means it doesn’t have an ECO option either. I’m using air cooling, and my room tends to get very warm in summer (above 50°C), so switching to ECO helps lower the clock speed and cut down the heat output significantly.
Ah, ok... i see. I liked pbo, it was fun, but near useless on the 3600, except yeah, i actually used it to lower temps, -50mv, +200mhz "offset" or something... it ran 5-10c cooler at same or better performance, pretty neat! my room *can* get hot too, but it barely does actually... its only a few days per year though and then it's more like 30C , used to be more but we put some insulation that helps.
yeah, that's what i meant... i recall in the early days people would run crazy stuff like 99%/100% because "moar powerrr" ! lol and I was just curious if something actually changed in terms of official recommendations etc... i mean i woulda expect the power plan to reset after a processor change but nope, its still the same 85/100% that i set years ago... ps: yeah, as mentioned pbo is really cool, literally, lowers power consumption, improves performance (ideally) but the 3D doesn't have it (although it does, i hear RM has it and there's also a program called PBO2... ill look into that later as for now im happy the PC just runs with RAM overclock, and i dont feel it needs a lot of tuning, temps are also ok, actually very similar to my old R5 3600...)
I tried this on my Intel systems by setting them to 99% or 100% before switching to Ryzen. I wanted to maximize performance from my 5950X. It seems some recommend sticking with a balanced configuration rather than focusing solely on high-end settings, since Windows and AMD previously had their own Ryzen power plans but now integrate them more into the operating system. I might be mistaken, but that appears to be the case.
Sure, I've tried it before too. Windows Balanced consistently gave the best results, though not dramatically. Also, high performance tends to get hot and slows things down—probably because of the cooling. Makes sense!
