Ok so I had about an hour of idle time so I decided to try and lower my VCore a bit so here are the results, PState0 voltage @ 1187500.

1. Offset 0.062500 = 1.2500 stable
2. Offset 0.037500 = 1.2250 stable
3. Offset 0.012500 = 1.2000 unstable

All I changed in PState0 is the FID to match my desired OC, changing VID and DID causes instability in my tests. To compensate for the low voltage in PState you have to set CPU Voltage VCore to offset and add a value that you know is stable for your OC.

In my case: (PState0 1187500 ) + (VCore Offset 0.11250) = 1.3 VCore
I know could go lower but I was too lazy to test lower offset values. lol.

Your VCore seems to be above the PState VID value, unless both HWMonitor and CPU-Z are reading the processor VID. I was going to say 3700MHz below a VCore of 1.2V is great, but ~1.3V is not bad at all.

You are demonstrating how simple it is to OC Ryzen. Just set PState0 to Custom, enabling it. Very little set in OC Tweaker for the OC, just VCore mode to Offset. If you set CPU Frequency and Voltage Change to Manual, and set the CPU Frequency above the normal Turbo speed, that will also change the Frequency in PState0. So an easy way to change the frequency, without changing the FID and DID. If the VID is then not enough, just select an Offset Voltage on OC Tweaker, with the + key.

It really is that easy to OC Ryzen but you don't really need the extra Mhz all the time so with this you can save on power consumption and have the the processing power when you need it.

Hope this helps. :)

I do have one more question.

VCore mode of Offset is not a default as I recall, but that doesn't matter. Is the Offset voltage set to Auto?

I'm just trying to see if the default PState0 VID for a 1700 is 3a (1.1875V), which is quite different than my 1700X whose PState0 VID is 20 (1.35V). I've changed settings in OC Tweaker, that can affect PState0, so I need to clear the UEFI and start over.

Forgot to say earlier, Turbo must be enabled by default, there is no option to disable/enable it. Intel over clocking boards normally have that option.

Your VCore seems to be above the PState VID value, unless both HWMonitor and CPU-Z are reading the processor VID. I was going to say 3700MHz below a VCore of 1.2V is great, but ~1.3V is not bad at all.

Yes.

Did you configure anything for the processor (speed, VCore) in the OC Tweaker screen?

No.

If not, the core speed in PState0 was set to 3700MHz by default?

See first screenshot.

Interesting you get the down clocks you do with Cool n Quiet disabled.

Sorry CnC is enabled. Funny thing is I don't actually see any downclock below 1300Mhz when I'm obeserving CPU-Z or HWMonitor it only appears in HWMonitors logs when I leave my computer idle for hours or overnight. Note that in Power Settings "Put computer to sleep is set to NEVER".

Any idea what the crazy low Minimum core clock speeds in HWMonitor are about? We can't see what the BCLK readings are in the HWMonitor information, which tends to wander a bit on ASRock Ryzen boards that don't have a BCLK setting. Your max core speed is over 3800MHz, which could be due to a slightly higher BCLK. We can see the affect of a lower BCLK in the CPU-Z information.

Nope I have no idea, see previous answer.

Here's my OC results using PState (no crashes, freezes in 3 weeks)

OC = 3.7Ghz (cores go beyond that, turbo may still be kicking in)
Cool and Quiet = Enable
CState = Auto or Enable (if set to Disable downclocks don't go down that much)
PState0 = custom all the rest set to Auto
Minimum Power State = 40% (5% to 41% same downclocks, 42% to 70% = 2460Mhz, 71% to 90 = no downclocks)

I want to say first that my goal is NOT to prove something is true or false, but simply to learn how PStates work and how they are related to the Windows Power Plan, and other things like the Ryzen CPU power saving options Cool n Quiet and C6 C State.

I set the OC Tweaker OC Mode to Auto, and only had the PState0 configured with my OC of 3925MHz. PState0 is set to Custom, all others on Auto. I set the VCore in OC Tweaker to Offset mode, 1.35V, with an offset voltage of 0.00625V. That is close if not exactly how your PState0 is configured, and I'm not sure what you have configured for VCore in the OC Tweaker screen. You seem to have done that via the FID.

With Minimum Processor state set to 10% with the configuration above, I only get three core speeds, or core multiplier values, as shown in HWiNFO. The multipliers are 39.25, 22, and 19.625.

I have screenshots of HWiNFO showing the multipliers and core power usage, but the image hosting site I use is not working Angry

so I'll post those soon.

With Minimum Processor state set to 90% with the configuration above, I only get one core speed and core multiplier value, the 39.25 multiplier.

I did a further test, setting several PStates to Custom, up to the 800MHz speed PState. The result at 10% and 90% Processor State were the same as only using PState0 set to Custom.

So, interesting that I only get three core speeds so far, the lowest being 1962.5MHz. I have some information from the HWiNFO sensor display that seems to show lower core power usage at the lower Minimum Processor state value than at the higher value. That may simply be due to less (unseen) core throttling at the higher Minimum Processor state, but we need to look at the data first before making any decisions.

I understand the core frequencies you get using PStates. My question to you is, do you have Cool N Quiet and C6 C State enabled? If they are not set to Disabled, Auto can be enabled.

I have a problem with not being able to see the core frequencies reduced with Minimum processor state set to 90%, and that it somehow happen internally. I use HWiNFO64, and I assume you mean programs like that, not Windows Resource Monitor, for example can't show that.

Does your HWiNFO display show the individual core power usage readings? Mine does, and IMO if the core frequencies were internally down clocking, that would be reflected in the core power usage readings. I'm not on my Ryzen PC now, but as I recall the core power readings are not the same with Processor Minimum state at 90%. I'll need to check that to be certain.

Consider, if the High Performance power plan is actually behind the scenes doing the same thing as the Balanced plan regarding the core speeds and power usage of the CPU, then what is the point of the Minimum processor setting in High Performance? A lie to the user so they think it is different?

Hmm, so even with Minimum Processor state at 90%, you see the reduction in core speeds? That is not what I get. I need to review your configuration again.

For current Intel boards, HWiNFO displays the percentage of time the processor is in the various power states, C0 through C7. That is not the case for Ryzen boards, I wish they did.

Hi, bold quotes answered below:

Yes, I have Cool&Quiet and C6 states enabled in UEFI.

Yes, I use HWinfo64, not Windows.

I'm not at my PC now, I'll check at night when at home and give you my findings. I remember I read somewhere Ryzen has advanced power savings and clock gates which work internally without exposing changes to monitoring programs due to the speed those power changes happens, but take it with a grain of salt because it's not official words.

I think this plan disables the lower power states and core parking, hence the name, but not sure if it changes frequencies by altering the minimum. I'll check it at night.

Cheers.
