Hello, In the bios 2.50, there is a way to o/c via Pstates. It's working but only for the P0 state. It suppose to go lower (P1, P2) if the cpu is less use but it stay block in P0. I use this configuration:  And auto in the OC Tweaker:  So it's half working because i'm @3.9Ghz. But it never go lower and i expect 3.8Ghz when in idle. I tried with the other Pstate in auto or disable and my power-plan in windows in balanced. Someone was able to make it work? Use P1 or P2.

" rel="nofollow - on my taichi the p state 1 2 and 3 etc all step down when enabled or set auto have you checked they are not actually lower power by default ? ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

I don't understand what you mean with " lower power by default ". My Pstate configuration is on the first post. P0 = 3.9Ghz P1 = 3.8Ghz So when i'm in idle i except 3.8Ghz, but i stay @3.9Ghz  ------------- AMD R7-1700 @3.85Ghz 1.33V + Noctua NH-D15S ASRock AB350 Pro4 G.Skill Ripjaws V Kit 2x8GB @3066 16-18-18-39 AMD Radeon RX 480 MSI GAMING X 4Go Samsung 960 EVO 250GB SSD M.2 2280 |

| hey, i had similar problems on mine although i have a a 370 gaming k4. the workaround that worked for me and other is not to change the p0 voltage. leave it to whatever it was stock and only change the frequency and use vcore offset to set it to your desired level. if you change the voltage in the p0 it tends to stay lock to p0 OR p1 and not change p states. also check you power plan adv setting to see/set min frequency % allowed by it. |

SiX-P4cK, I have the ASRock X370 Killer SLI/ac board, and I was able to get a lower P-State working. Our boards have different UEFI/BIOS, so I cannot guarantee this will work on your board. You seem to be using the standard Windows Balanced Power Plan, and not the Ryzen Balanced Power Plan, right? When I used the Ryzen Balanced Power Plan, my method did NOT work. I just got the multiple PState levels to work for the first time, so I'm still learning how to use them. This is using the Windows Balanced Power Plan, default Processor settings. Questions: Do you have Cool N Quiet enabled? Do you have Global C States enabled? I have both of those options enabled. I have my CPU OC to 3.925GHz configured in the OC Tweaker screen, not just in the Custom Pstates screen. CPU Frequency and Voltage Change is set to Manual. Here's a screenshot of the Custom Core Pstates screen:  Custom Pstate0 is my OC. I have the same frequency and VCore set in the OC Tweaker screen. I'm using Offset Voltage mode, Offset Voltage value set to Auto. Notice that Custom Pstate1 is set to Auto. Custom Pstate2, set to Custom, is really the default/automatic Pstate2 that the UEFI provides. Task Manager is not the best way to monitor the changes in processor speed, but since you used it in your example, I will too:  Notice my Maximum speed is 3.92 GHz. This is a better example of the processor cores at different speeds:  As I said, this is my first success experimenting with Pstates. I have much more experimenting and testing to do. I suggest you try a lower frequency than 3.8GHz for the lower Pstate, at least as a test until you can control it as you want it to work. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Hello, Thx for your answers. My MB doesn't have the vcore offset option, so i can't use this trick. I hope they will add it later because i have massive vdrop in charge: 1.375V configure in bios, 1.35 in idle and 1.26~1.28 in charge On the next screen is with a fix vcore, just when i launch prime95  I tried with both: standard Windows Balanced Power Plan and the Ryzen Balanced Power Plan. But it doesn't change. My screen with the task maanger was to show i'm in idle, not in charge. I use also HWiNFO to monitor. Yes C&Q and Global C States enable. I will try later like you with P0 = max o/c, P1 auto, P2 lower frequency like 3.2Ghz ------------- AMD R7-1700 @3.85Ghz 1.33V + Noctua NH-D15S ASRock AB350 Pro4 G.Skill Ripjaws V Kit 2x8GB @3066 16-18-18-39 AMD Radeon RX 480 MSI GAMING X 4Go Samsung 960 EVO 250GB SSD M.2 2280 |
