" rel="nofollow - Looking for a fix. Windows task manager is reporting the wrong CPU speed. I see a lot of people with the same problem and no one seems to know whats up. I want to say that it is a bug with Windows running in UEFI bios mode. I came to this conclusion because I never had this problem until today when I reinstalled Windows in UEFI bios mode. I also noticed that the other people complaining about this problem were either running Windows 8 and up. So I don't know if it is a Windows problem itself or if I have to disable something in the bios? Anyone else have this issue? My specs.... Windows 10 Pro 1709 (Build 16299.248) operating on a X370 Killer SLI/ac (BIOS 4.50) running an AMD Ryzen 7 1700 with Corsair Ven. LPX 2666 (2x 8GB) ------------- X370 Killer SLI/ac - Ryzen 7 1700 - Corsair Veng. LPX 2666 (2x8) - 4x 120GB SSD AMD RAID0 |

krj7709, please post screenshots of CPU-Z and the erroneous Task Manager numbers. Remember that these processors have Cool-n-Quiet which vary the CPU clock. You may be able to disable that in your BIOS/UEFI. Enjoy, John.

I know that the cpu is suposed to throttle. It didn't do this until I reinstalled Windows in UEFI mode. ------------- X370 Killer SLI/ac - Ryzen 7 1700 - Corsair Veng. LPX 2666 (2x8) - 4x 120GB SSD AMD RAID0 |

I know the cause of this its 4.50 Bios. I have same problems as yours windows previously reporting wrong clockspeed of CPU but BIOS, HWmonitor or CPUZ reporting correct information. The fix is update it to 4.60. ------------- Ryzen 5 1600 3.80ghz @1.3375v Asrock X370 Gaming X 5.20 Bios CM MA610P Aorus Xtreme Gtx1080ti Gskill Trident Z RGB F4-300016D-16GTZR @2800mhz SamsungEvo 250 2Tb Firecuda 1Tb WDBlack Corsair RM650X |

" rel="nofollow - If this is fixed by updating the BIOS then it must mean that Windows Task Manager is taking its reading from somewhere different from what CPU-Z is measuring. Then again, what is Task Manager actually showing? CPU-Z is monitoring core 0 in that screen grab. HWMonitor is showing all the cores. But it's not at all clear what Task Manager is trying to show, though it's definitely wrong. ------------- ASRock Fatal1ty AB350 ITX P4.90, AMD Ryzen 5 2400G, 2x8GB Corsair CMK16GX4M2A2666C16, 250GB Samsung 960EVO, 500GB Samsung 850EVO, 4TB WD Blue, Windows 10 Pro 64, Corsair SF450, Cooler Master Elite 110 |

Windows reporting! I see the same here. Windows is not "Real Time" |

" rel="nofollow - I don't think any of them are quite "real-time" and don't know if there is one that is truly real-time? - I want to say but am not 100% certain. When I first got the Ryzen hardware, before updating the BIOS, it was in-sync. I of course updated bios and installed cpu-z and hw-mon and oc'd. I just happen to notice the out-of-sync clock later. Right now I'm running on the base clock and its still out of whack but I'm experiencing some other odd issues that have set the mis-match on the back burner. The main issue is random lag. Another issue is wireless keyboard/mouse cutting in/out with a usb stick plugged in the usb slot next to receiver. But thats all for a later thread/topic. ------------- X370 Killer SLI/ac - Ryzen 7 1700 - Corsair Veng. LPX 2666 (2x8) - 4x 120GB SSD AMD RAID0 |

" rel="nofollow - what is your timer resolution at? (like when u set it to 1.0 if it stays at 1.0 or shows less/more) anyway if your windows time (clock) isnt affected, then u have no issues, and its just windows bug due to power saving stuffs if your time is incorrect, then u may have performance issues also hpet is enabled rite? ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

" rel="nofollow - @krj7709, what is your BIOS version? Because the latest BIOS fix my windows incorrect CPU speed information. ------------- Ryzen 5 1600 3.80ghz @1.3375v Asrock X370 Gaming X 5.20 Bios CM MA610P Aorus Xtreme Gtx1080ti Gskill Trident Z RGB F4-300016D-16GTZR @2800mhz SamsungEvo 250 2Tb Firecuda 1Tb WDBlack Corsair RM650X |

It was doing it with 4.50, 4.60 and L4.61. It is something with one of the later Windows updates. I installed Windows 10 LTSB and the issue goes away. So... I'll run My Windows 10 Pro and deal with the clock not reporting correctly. ------------- X370 Killer SLI/ac - Ryzen 7 1700 - Corsair Veng. LPX 2666 (2x8) - 4x 120GB SSD AMD RAID0 |

This is the issue we are all facing as Ryzen users. We can never tell where the issue is coming from. I spent a month troubleshooting my system for random hangups (not freezing, it would resume after 4 - 5 seconds), I replaced every component and the issue persisted. Reinstalled the OS about a dozen times and nothing. Eventually, by chance, I lost my regular Win 10 install key and had to download and make a new one. Suddenly, my system ran flawlessly..... It turned out that there was an update that was failing to install on the older install version, the new version included it in the installer and problems all went away. I do not like this new OS system from MS at all. I much preferred service packs and new versions. Almost 0 transparency about what each (forced) update does and no way to tell what is broken half the time. I have not needed to go through the guts of my OS this much since my days building and configuring NT 4 servers...... At least we are slowly moving forward... -------------
