As title says, recent tests including cinebench and [userbenchmark](http://www.userbenchmark.com/UserRun/3793558) have indicated my cpu is not working properly.

userbenchmark noted that cpu was throttled by 39% by windows, but the solution they gave didn't help.

Quick info. 3.95 overclock on 1.36V
Ram untouched (but this isn't problem as system was fine before.)

Any and all suggestions I will attempt and will report back. Thank you all.

I suspect your CPU is downclocking under load.

Did you do proper stability and thermal testing on your OC? From what I've seen, 3.95Ghz is pretty high OC on Ryzen for 1.36V. I believe most people are pushing close to or over 1.4V to approach the 4Ghz mark.

Use HW-Monitor to watch temps and CPU-Z to monitor clock speeds under load. If the temps get too high then you need better cooling, or lower voltages (probably won't be stable without lower clocks too). If your temps are fine but the frequency bounces around you'll need a little more voltage, or lower clocks.

If you mean the solution given by userbench, it does not fully detail what should be done.
Go here to obtain the latest Chipset driver which also includes the latest AMD Ryzen Power Plan for Windows 10 64bit. http://support.amd.com/en-us/download/chipset?os=Windows+10+-+64
Once installed go to your Power options and set for Performance and see how you go.
You can read up on the new plan here: https://community.amd.com/community/gaming/blog/2017/04/06/amd-ryzen-community-update-3
Please report back.

Added Voltage, fixed problem!

Glad it's sorted. Can I just encourage you again to take an hour or so and do some proper thermal and stability testing. It's a good idea to spend some time with artificial worst-case scenarios and make sure everything stays stable and temps are under control. That way you can be relatively sure that your OC is safe and is actually providing the performance boost you're hoping for, and not actually causing problems like they can when they're not quite right.
