" rel="nofollow - I have watched a video on how to OC the X370 Taichi M/B using the Pstate method. Everything makes sense except I can't find the BIOS option under Advanced>AMD CBS>Zen Common Options>Custom Core Pstates>Accept. Did version 3.00 change or move the "Custom Core Pstates" entry? I have changed everything back in the OC Tweaker section to Auto. Yet the Pstate0 and Pstate1 show the OC settings I had set in the OC Tweaker when Pstate0 or Pstate1 "Custom" is selected. That's all fine and good except the BIOS will not let me change any of the Pstate entries. It always sets them back to the original value! So...I need to find how to Accept Custom Core Pstates or determine what other setting is keeping this option from showing? Help would be greatly appreciated. I tried Disabling "Global LC State Control" and now I can change the entries in Pstae0 and Pstate1. I guess that's progress but the only reason I'm playing with Pstate OC'ing is to get the system to down clock and down Vcore when the system is idle. That ain't happening according to CPU-Z 1.80. At least when I used the OC Tweaker method the Vcore dropped down when the system was idle?! |

" rel="nofollow - parsec or whomever has OC'd the X370 Taichi/Ryzen, I updated the BIOS to 3.00 and changed the OC'ing method to Pstate CPU @ 3800 MHz @ 127.500V with the memory on Profile1 2933 and the boot time from pressing the power button to the first BIOS screen takes < 9 seconds. That is down from the ~19 seconds it used to take! I tried booting on v3.00 using the OC Tweaker method and it took ~19 seconds. So...Pstate OC'ing has at least one advantage. I Enabled "Global LC State Control" and that allows the Vcore to drop from ~126.000uV to <.500V when Idle but the frequency does not change? I'm still confused on why the Pstate2 settings don't seem to work since the minimum frequency is set to 2200 MHz and the minimum voltage is set to .900V. When I reset everything to Default the system does what it almost is supposed to do, it drops the Vcore down to <.500V and down clocks the CPU to 2200MHz. That's close to what I would expect except Pstate2 says the minimum Vcore should b .900V? Am I the only one with this "problem" when OC'ing the Ryzen X1700 on the ASRock X370 Taichi M/B? Comments please! |

| " rel="nofollow - One more issue that I'm having with BIOS version 3.00, The Windows Restart option (Restart, Shutdown and Sleep) goes directly back into Windows. It does not give you the chance to enter the BIOS. It now acts like The "ASRock Restart to UEFI" did when the system was OC'd on BIOS version 2.40. Now with V3.00 I get an added bonus - "ASRock Restart to UEFI" hangs the system whether I have the BIOS set to Defaults or OC'd! One step forward and three backward? |

" rel="nofollow - Thanks to the suggestions in this thread I final got Mr. Ryzen to do what it should: http://forum.asrock.com/forum_posts.asp?TID=5354&title=x370-taichi-pstate-oc-bug I ended up with: Pstate0 set to Custom 98-8-2C Pstate1 set to Auto 98-8-2C Pstate2 set to Custom 84-8-68 Pstate 3,4... set to Disabled Power Plan-Minimum Processor State set to 40% Don't ask me why or how but the system seems to run as expected with the down voltage and down clock matching the settings in Pstate2. Unfortunately, Restart still goes directly back into Windows. Is this BIOS Version 3.00 bug or is there some other magic setting I'm missing that will fix this...or...am I the only person with this problem? |

" rel="nofollow - Looks like I'm talking to myself but then it makes me feel better! I now have the system running on the following settings: Pstate0 set to Custom 9c-8-22 Pstate1 set to Auto Pstate2 set to Custom 84-8-68 (Defaults?) Pstate3,4...set to Disabled Power Plan-Minimum Processor State set to 40% The system is stable at 3900, at least it runs IBT for 10 passes and runs Handbrake for over an hour converting Blu Ray discs to MP4 files. I don't know if it is factual but Handbrake seems to be the best stability test since it keeps all 16 threads running at close to 100%. And...when I put the source file on an SSD vs a standard hard drive the processor wants a notch or two more voltage?? The only problems I am aware of at this time are: The Windows Restart option does not show the BIOS post screen - it just reboots Windows! The ASRock Restart to UEFI program hangs the system! The ASRock AI-Tuning program gets a Division by Zero when loading! None of these are game breakers but...do not instill confidence. Also,does the latest version of the BIOS (3.0) allow the GSkill 3200-14 memory to run at the stated speed? |

1. as of now I dont see a way to config Power Plan-Minimum Processor State in windows advanced power settings, like it doesnt show minimum processor frequency field.....so i am gonna try ur settings...do you have to enable global c-states?... 2. yes.. bios 3.0 allow 3200-14 to run at stated speed..just enable xmp profile and give it a SOC voltage of at least 1.1 (i use 1.1) and DRAM voltage at least 1.35 (i use 1.4)

yah i set pstate1 to auto, p0 = 3900, p2 to @1500 7c/10/6c (also can use @2200 84/c/68), it is working up/down voltage, clocking is on 3900 not changing.... in power plan i can't set minimum...only see a maximum..I downloaded ryzen power plan, same thing, also most ppl say to use windows high performance and not the ryzen one. pic -> http://imgur.com/Bvm5n93 |

Here is where I found a link to downloaded the latest chipset drivers. https://community.amd.com/community/gaming/blog/2017/04/06/amd-ryzen-community-update-3" rel="nofollow - https://community.amd.com/community/gaming/blog/2017/04/06/amd-ryzen-community-update-3 If you have the "AMD Ryzen Balanced" power plan showing up under Power in the Control Panel then select as follows: Change Plan Settings>Change Advanced Settings>Processor Power Management>Minimum Processor State. I set it to 5% on Battery and 40% when plugged in. Works as advertised for me! |

yah not sure what i am doing wrong, Minimum Processor State does not show up. can you tell me what you disabled/enabled in bios? such as AMD cool quiet, c6, global c-states etc? and for pstate1 did you put on same as pstate0 or used AUTO? |

These are the only BIOS settings from the Defaults I changed or may have changed back to the Defaults along the way: Overclock Mode - Auto CPU Frequency and Voltage Change - Auto Load XMP Setting - XMP 2.0 Profile1 (EVGA 3000-15 Memory) Voltage Mode - Stable CPU Core Voltage - Auto CPU Load-Line Calibration - Level 2 VDDCR Load-Line Calibration - Level 2 Global C-State Control - Disable (To make changes to Pstate0 stick) Global C-State Control - Enabled (After making changes to Pstate0) Pstate1 - Auto Pstate2 - Auto Pstate3 = Disabled Hope this helps, but I don't think the BIOS settings have much todo with the AMD Ryzen Power Plan. You might want to rerun the Ryzen chipset drivers from the site mentioned above. |

not booting unless i specify an offset voltage...what 3 hex values did u use for pstate0? do u have to reboot before changing c-state from disable to enable?

I don't know what else I can offer. Every setting I have played with is in this thread. You might try the old fallback position and CLR CMOS, Load Defaults and go from there. No, I just leave it Disabled most of time since I forget to Enable it. Don't know what difference it makes. |

There is no magic in PState over clocking, meaning it will be no different or better than using the manual settings in OC Tweaker. Frankly all the higher (lower speed) PStates (1, 2, etc) are only useful for down-clocking the core speeds under low CPU loads. If we use the Ryzen "Balanced" power plan, you won't get any down-clocking of the cores, since the Minimum Processor State is set to at least 95% if I recall correctly. The Reset Defaults option for the Ryzen Balanced plan does not work. So with the default settings of the Ryzen Balanced power plan, supplied by AMD, we cannot use the lower PState core speeds. Also, where is AMD's guide for using PStates with Ryzen processors?  If we go into a PState form, and just begin changing things without understanding what they do, we can only blame ourselves if the results are strange or failure. I have not spent enough time studying PStates to describe them appropriately, but if we need to ask what hexadecimal value to use for the VCore, then we are just stumbling around in the dark and cookbook over clocking. After changing to the Windows Balanced plan, or setting the Minimum Processor State in the Ryzen plan to a low value (I use 5%), I can get the core speeds to drop to 2,200MHz. I also have CnQ enabled, and C6 enabled. My OC is 3,925MHz, to keep it above 3,900MHz with the drooping BCLK. I have PState0 set to Custom, PState1 set to Auto, and PState2 set to Custom. I changed nothing else on the PState forms. The hierarchy of PStates is PState0 is the highest processor speed, all the other are simply lower core speeds. Setting the VCore with a Hexadecimal value without any control over the VCore mode (ie, fixed, offset, etc) is not entirely useful, and causes us to use the OC Tweaker screen to set the VCore mode. The 2,200MHz core speed is PState2, since as we know PState0 is the same as our manual OC in OC Tweaker, it is mirrored in PState0. Or at least it is with the UEFI (3.00 and earlier versions) for my X370 Killer SLI/ac board. I cannot comment on how the X370 Taichi board's UEFI behaves, I don't have that board. As you know now, enabling a PState is done by setting it to Custom. Skipping or ignoring a PState is done by setting it to Auto. Disabling a PState disables all the others below it. Since the PState0 is the default processor speed, OR the OC speed if you OC, be sure you verify that the settings in OC Tweaker match those of PState0. With my board's UEFI, the OC Tweaker settings are automatically transferred to PState0. But if I modify the PState0 form, the changes are NOT transferred to the OC Tweaker screen. Whether or not that should happen, I'm not sure yet. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - parsec, What you stated above don't work for me. If I use the OC Tweaker method to OC @3.8 the system does not down clock or drop the voltage when Windows settles down! Also, the "Minimum Processor State" does not show up under "Processor Power Management" in the AMD Ryzen Balanced Power Plan! So I could not go in and change it to your 5%? However, if I change PstateO to Custom Pstate1 to Auto and Pstate2 to Custom everything works as advertised even the Minimun Processor State is available. So...the key to down clocking was the changes made to the Pstate settings. I only stumbled into the solution by going to the Pstate method based on several different postings. Using the OC Tweaker does the hex conversion automatically in the Pstates. I agree much simpler although once you understand the Hex and how it's used it ain't that complicated. Now, what about my original questions concerning the ASRock A-Tuning- division by zero error, ASRock Restart to UEFI - hanging the system and the Windows Restart - skipping the BIOS screen? Am I the only guy with this issues or is there something I'm doing wrong? It seems like BIOS V3.00 made these issues get worse? Also, did 3.00 allow you to run your memory at 3200-14? One more thing, when I try the OC Tweater method of Oc'ing the boot time to the first BIOS screen goes to ~20 seconds. When I use the Pstate method the boot time to the first BIOS screen goes back to ~10 seconds. Obviously the BIOS is going through some extra somethings to when using the OC Tweaker OC'ng method?! |

Regarding the difference in using and not using the PStates (Custom = On, Auto = Off), the Ryzen power plan Minimum processor state setting, and the cores down-clocking, I agree that the cores do NOT down-clock unless the other, non-0 PState is set to Custom (in use.) It's been a while since I have not had the PStates active, so I'll need to check that. But as I recall, I agree that the cores will not down-clock, even when using the Windows Balanced or Power Saver plan, with Minimum processor state set to 5%. That is, even with CnQ and C6 C State enabled. I do see the VCore dropping below 0.400V (in HWiNFO64) with the CPU power saving options enabled, and Minimum processor state set to 5%. I have yet to find a way besides using the lower core speed PStates to get the cores to down-clock. That seems odd to me, since core down-clocking is not an exotic, new feature. I'm also not sure about the length of POST time to the UEFI/BIOS screen when OC Tweaker over clocking, with PStates off. I'll need to check that. Do you have AM4 Advance Boot Training enabled or disabled? Currently the cold boot Windows Task Manager Last BIOS time today was 8.9 seconds. My different board's different version of A-Tuning (ver:3.0.132) runs fine. Do you get that error when you run it? Restart to UEFI with my board will not automatically put me into the UEFI IF my memory is over clocked. So it does skip going into the UEFI screen in that situation. I do not get any hanging of the system using Restart to UEFI, I'm not sure what you mean by that. I've mentioned the issue with Restart to UEFI in other threads, you must have missed it. No, you are not the only one to have that problem, although it seems you have more problems with it than I do. Not much if anything you can do wrong using Restart to UEFI. It has worked flawlessly for me on... at least eight ASRock Intel chipset boards. The failure to work on my Ryzen PC is the first time I have seen it not work correctly, again ONLY when my memory is over clocked. Restart to UEFI is based upon a Window feature introduced in Windows 8, so I am unsure where the blame for its failure to work lies. I'm still unable to run my memory above 2933 with AGESA 1.0.0.6a/UEFI 3.00. But I haven't spent much time trying. I have some new timings that supposedly work with Samsung B-die memory, different than the XMP profile values, but so far they don't make a difference. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - parsec, I agree, when I had the system down clocking using OC Tweaker the Vcore would drop to ~.400V which I found a bit troublesome since the Pstate2 said it should drop to .900V. Using the Pstate method of OC'ing the down clock does exactly what it supposed to do - 2200MHz and .900V (the values in Pstate2). I have AM4 Advanced Boot Training Disabled (the Default?). What is it and should I have it Enabled? When I say ~10 seconds to get to the first BIOS boot screen I mean from the time I hit the Power Button on the Case until the ASRock splash screen appears with the options to boot into the BIOS. Something changed with version 3.0 since now the Task Manager BIOS time changed from ~9 seconds to ~16 seconds. The 16 seconds is about the time it takes from the Power Button to Windows 10 appearing? I uninstalled A-Tuning and Restart to UEFI on the Ryzen system. When I said Restart to UEFI hung the system I meant it hung the system in the BIOS. The only way to get the system to work again was to turn the power off at the P/S turn it back on and Boot. I guess I'll keep my $200 dollars in the bank and keep using the EVGA 3000-15 memory. Please let me know if you ever get the GSkill Flare X memory running at 3200-14. I wonder if I should try the A-Tuning and Restart to UEFI programs for the SLI M/B download page since it appears to be newer versions? Can't be any worse than what I got from the Taichi M/B download page?! |

Do you have Cool N Quiet and C6 C State enabled? It is the C6 C State that must cause the VCore to drop below 0.400V (mine goes to 0.384V). I've used my Ryzen PC configured like that for a long time, and I never have any problems. I also see a VCore of 0.900V at times, but the C6 C State must not be active at that time. If I am not using the PState2 entry (all PStates set to Auto), with C6 enabled, I still see the VCore drop to ~0.400V, while the core speed is still at my OC of 3900MHz. The PC is stable at that time. The AM4 Advance Boot Training option has been enabled by default in the past. I still think it is, but your board's UEFI defaults might be different. If you enable that option, the POST/startup time will be even longer, much longer. Are you sure it is disabled? What you describe about the Task Manager Last BIOS time sounds like AM4 Advance Boot Training is enabled. Since Restart to UEFI does not work for me when my memory is over clocked, I rarely use it. I have never had Restart to UEFI hang the PC in the UEFI. The only thing it did does is, if I try using it, but then press the Del key when the PC restarts so I know I can get into the UEFI, I get into it fine. I can use it fine, but when I then click Save and Exit, the PC shuts off and stays off. I must press the power button to get it started. So it seems Restart to UEFI behaves differently with your board or board's UEFI then my board. Restart to UEFI is the same version on both of our board's download pages, ver:1.0.5. Restart to UEFI is a Windows program, and is the same version for Intel boards, ver:1.0.5 is the latest I can find. Again, it is based on a Windows feature, so I am not sure where the problem is, Windows, or Ryzen, or ?? A-Tuning on both of the X370 Killer SLI board download pages is version ver:3.0.132. The version on the X370 Taichi is ASRock A-Tuning Taichi utility ver:3.0.135, and dated a few days younger. So I don't understand why you think it is a newer version. Your board's Beta version is ASRock A-Tuning utility ver:3.0.131. Are you using the ASRock A-Tuning Taichi utility ver:3.0.135 now, or what? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - parsec, Yes. I have cool N Quiet, C6 C State Enabled. Yep, I Enabled AM4 Advanced Training and the boot time increased ~10 seconds. Sorry for the confusion, I was using A-Tuning v3.0.135 and Restart to UEFI v1.0.5. I just made a quick ASSUMPTION, without checking the download page, that your board was using different versions since you are getting different results. I've learned to live without either of these programs so it is no big deal. Just wanted to post my issues so that MAYBE just maybe someone from ASRock will notice?! |

parsec, Figure this one out! I downloaded from the Taichi M/B site A-Tuning and Restart to UEFI and re-installed them. Both utilities now work as advertised - A-Tuning does not get the division by zero error and Restart to UEFI allows me to restart to the BIOS!! I don't know if re-installing after the V3.0 BIOS update or Pstate OC'ing fixed the problems but I'll take the results. You might want to try the Pstate settings I'm using to OC and see if that makes any difference for you. |
