" rel="nofollow - Hi all,

Any idea how I make the clock speed stable?

In other words, when looking at the task manager, the speed of the CPU goes up and down constantly. I believe this is having a performance impact overall. Any idea how to make it constant?

I have Ryzen 1800x with a x370 Taichi.

mrpepelepeu, don't really know what you are asking. Perhaps you could post a screen shot and point out what you are seeing. If you do not like the CPU clock speed varying, then go into the BIOS and Disable AMD Cool-n-Quiet. Enjoy, John.

Thank you.

Yes, that was it. I disabled cool-n-quiet and now it shows a constant speed.

Thanks.
