Well, different architectures yada-yada. Use stock for this to fucntion properly or usse PStates 🙂 Also keep in my that those power saves are about 15-20W at best as buildzoid measured in his videos. Not much to worry about.
It's easy to try out, I did not managed to test this.
Just change the idle cpu % in ryzen power plan no need to change p state. Works like a charm. I have set it to 40% and my CPU is idling at 2.1GHz approx.
I had a look and my Ryzen power plan has disappeared. I'm not sure whether this was due to the latest cumulative updated for Windows 10, or because I did a clean install of my Crimson Relive driver when 17.7.2 came out.
Either way, at default setting the CPU idle states work just fine, Ryzen power plan or not. My problem is that the seem to stop working as soon as you overclock via multiplier in BIOS.
Yes you are right not working while I set a manual multiplier in bios. How ever I have gone through some articles which says a Pstate overclocking is not always stable due to again bios is not rock solid till date. And the only benefit you might get is slightly less power consumption which does not matter a lot. Again some people has shown that the difference of watt while idling is also differs less even all cores are idling at 3.9 or 3.8. But if you use Ryzen master only to overclock in that case what will happen?
Have you noticed automatic voltage up while you type and fix a multiplier? For my case if cpb off the core voltage is 1.275max, cpb of 1.42v max, but typed 38 multiplier then the voltage is 1.41v max but the core voltage option is set to auto in bios. even -ve offset not decreasing the voltage much though in the bios it is showing less only in the offset field. My default processor volt is 1.375v.
I must admit, voltage readings confuse the crap out of me. I have no idea what the most reliable source for the actual set vs current core voltage is. When I applied the overclock, I did it using the minimum possible voltage bump (+0.00625 or something). I don't really want to push voltage at this point seeing as a) I'm still running the stock cooler, and b) it may not be necessary for a stable 3.8 which is all I'm shooting for at this point.
Either way, I'm really just tinkering right now. I enjoyed pushing my old FX6300, and given the huge benefit to be had from overclocking Ryzen, I just had to scratch that itch. There's no real rush; even at stock the 1600 is smokingly fast in every task you throw at it. I'm more than willing to wait until things stabilize a bit more on the BIOS end. Plus, Unlike some unluckier folks, I've had zero trouble getting my RAM stable at the 2966 XMP profile.
