Ryzen 1700 core0 mysterious high usage  

post #1 of 2
Thread Starter 
I started noticing this last week after my machine had been up and running for a couple days. It seems to be 3-4 days of being on 24/7 before this issue appears.

I fire up a game and notice reduced frame rate, sometimes drastic. HWinfo shows core0 pegged at 100% while the other cores behave like usual.

I had a couple browsers open, twitch livestreamer and video player open when I started the game.

So I closed everything leaving only what boots with windows except HWinfo.

this is what I see

HWinfo and windows task manager do not seem to agree. I scrolled through task manager and could find nothing except a few processes using 5-6%

Restarting my machine does clear this issue up. But what the hell is using 77% of core 0 right now?

this is win8.1 and I have SMT off right now BTW. It's balanced power setting now, but I had the issue with high performance set before as well.

Some helpful mods on the official ASRock forums gave me a suggestion I'd never have considered. Windows update hanging and causing the strange core usage.

I always leave windows 8.1 set to check and notify of updates but not install so I never thought much of it causing problems.

Anyway yesterday afternoon I turned updates completely off. This morning when I was preparing for work core 0 was acting normal.

I need to give it 1 more day to be sure, but this seems to have been the culprit.

so dumb :smh:
