I have to second manolo and pinguinotuerto's comments below - is there any concrete evidence that core parking negatively affects performance for your application? Unless there's some data behind this I'd be wary of random tunings, especially deleting registry keys. So happy it was such a simple fix, before I started trying to replace hardware.Īlso I run Windows 7.FYI - Microsoft has a full documentation page on changing power settings in more advanced ways here: Since unparking, my CPU temps have come down too! So so so happy about this. I have the AMD FX-4350 Quad-Core Processor, 4200 Mhz and when I was looking at my resource monitor noticed that 3 of my cores were parked most of the time when I was streaming. Microsoft even made a hotfix for this very issue, I guess Windows 7 has difficulty with AMD's processors, and they designed a hotfix, well 2 actually, the 2nd one to unpark your cores. I didn't have a single freeze last night during my stream, the game was playable for once! I actually enjoyed myself. Long story short, I started streaming again very recently and running into the same exact problems and found this little suggestion on Tom's Hardware, and gave it a try and WOW, the improvement is drastic. Sent my PC back to cyber power 2x, they said nope everything is in working order. I even quit for 6 months because I couldn't figure out what the heck was the problem. I've been banging my head against a wall trying to figure out why I would be having these massive lags, high CPU warning's in OBS and my PC hanging, and even freezing almost every single time I streamed. I started streaming on Twitch last year, and purchased a new rig and everything just to do so. Ok, so I know this is a super old thread, but I wanted to comment. You don't need to reboot after using it either. Let me know what sort of results you guys get. If your system catches fire I had nothing to do with it. I personally have not seen a downside to it yet (fingers crossed) and of course, use at your own risk. It also allows you to modify the setting for battery profile as well (in case you use a laptop and aren't plugged in). Most of the fixes use registry keys, but that's an actual program to disable it. (It's called Parkcontrol partway down the page) If you use a AMD Bulldozer or Vishera, this improves system responsivness and performance! ![]() I personally have not seen a increase in power usage while monitoring with Argus Monitor and all my C-States still work (CPU clocks down and uses less power when not under load). It also has a downside as it increases power usage. I personally haven't tried gaming or streaming yet, so take this with a grain of salt. Basically anything that is sensitive to latency, such as encoding, gaming, and audio work shows improvements. It also has quantifiable results in some applications. Basically both inputs showed huge improvements in resposivness. It's the easiest to feel with my mouse and when typing. ![]() For instance my main computer never showed up as 'parked' in resource monitor, but after doing this I noticed a huge improvement in responsiveness and system latency. ![]() This can happen for a few micro-seconds and may even happen when the core is under load. I'm unsure of how Windows 8 deals with this and/or if it would show benefits on W8, but in Windows 7 it makes a huge difference.Ĭore parking is a feature that saves power by turning off cores with low workloads. This affects anything with more then two cores, which is pretty much all modern processors. ![]() I have a i5-3570k and I've also tried this on my laptop, which is a older Core2 T8300. I learned about disabling core parking earlier today as a way to reduce microstuttering and after doing it, it has increased my system responsiveness by I would say 400%. So, I don't know where to post this, but I thought it would be relevant to all streamers and the OBS community is growing so I thought I'd throw this in here.
