no one process is using that 7% which fluctuates like normal, it's just the total of various processes using 1-2% Turned windows updates off completely yesterday and this morning core 0 looked normal. I want to give it another day to be sure, but this seems most likely to be solved now. Thanks a lot wardog! Edited by mxpie - 23 Mar 2017 at 9:10pm |

In that pic, click on CPU to sort till you see the process(es) that are using that 7%

Was you last system a Ryzen system? So how can you compare the two, particularly with a completely new platform (Ryzen) that is clearly still in the early, find and fix the bugs and issues phase. Ryzen has a while to go before it has decent stabili, which is still not 100%... if that is ever reached on any system. I'm also not sure about the Windows update process continuing non-stop and using a core non-stop. The article said the Windows update process for 7 and 8.1 would get an error message: Unsupported Hardware
Your PC uses a processor that isn?™t supported on this version of Windows and you won?™t receive updates. After that, is the Windows update process continuing to try to get updates? Where is that error message being written? Multiple messages over and over on the same day? A more basic explanation is, as seen above, Unsupported hardware for Windows 8.1. One look at your screenshot tells it all. Why is the Windows core scheduler only using one core? Eight cores are available. You've got 0% usage on all the other seven cores! No wonder you have a frame rate reduction and even lag in your browser. You are effectively running a single core processor! You don't have the Core/Thread usage shown in HWiNFO, do you have two threads running in the one core? I have a mere quad core processor in my Z270 PC, and all four cores are doing a little something most of the time. I have never seen anything like your screenshot. One core out of eight is the only one active? When one core is loaded, another should immediately be used. Do you get that continuously? Are any of the other cores active at any time? Sorry, I'm not ranting at you, that is a terrible situation, I just cannot believe it!! Task to core assignment is a Windows or software operation. Unless something else is the culprit, this is a great (terrible) example of Windows 8.1 not supporting a Ryzen system. |

wouldn't the culprit process show in windows task manager though?
alright I'll do an experiment for tomorrow. I'll completely turn updates off and see what it's doing in the morning. If core 0 is still under high load I'll unplug ethernet and see if that frees it up. I never had this issue on my last system I just upgraded from though. Edited by mxpie - 23 Mar 2017 at 8:26am |

Are you sure it's "fully updated? Just sayin. I've known about this from Microsoft coming sooner rather than later. That load could be Windows Update hogging that core, getting no response from the WU servers. Great time to jump on the Windows 10 bandwagon The fun never ends |

I think this may be a BIOS issue but not sure.
I leave my system on 24/7 and restart every week or so when necessary. I noticed that every morning HWinfo and MSI afterburner show core0 hovering around 70-80% load, while windows task manager shows almost nothing. I've searched through processes and details and tried shutting down a few things like radeon settings. but nothing makes core0 reset to normal. see picture http://img.photobucket.com/albums/v16/Yasunori/892365_zpsmekfs74e.jpg~original The load is real and not misreporting because I get noticeably worse frame rates in single thread heavy games. I've even had it lag my browser. a reboot resets this behavior but it always returns the next morning. System: Ryzen 1700 ASRock Fatal1ty AB350 Gaming K4 BIOS 1.40 previously I tried 1.42 beta and had the same issue. I had SMT disabled. Was going to try re-enabling it but BIOS 1.40 does not have the option. All other settings default. Windows 8.1 new install, fully updated. Balanced power preference with sleep/hibernate disabled. I have not seen anyone else on various forums/reddit mention this 'bug'. and I've gotten no help identifying the issue. Edited by mxpie - 24 Mar 2017 at 10:33am |
