Hi,
Recently built a new gaming rig. The CPU is a Ryzen 5 1600. For the first day or two everything seemed fine. Then at some point, Windows has started massively underclocking my CPU, severely affecting my performance in games.
My temperatures are completely fine. 30 degrees idle, doesn't even hit 40 degrees under 100% load (probably because of the massive underclocking) so I can't imagine a thermal issue being the cause here.
In BIOS, everything appears normal. I've tried going with default settings, and manually setting to a certain CPU frequency (3.5ghz which is standard) but neither have an impact once Windows loads.
In HWInfo64, I can see that the ratio of the CPU's is being lowered to 15.5x - making the frequency of the CPU's a measly 1.5ghz. So, for some reason Windows is lowering my CPU ratio from the default of 35, down to 15.5.
No amount of CPU load appears to change the ratio.
I did notice at first that Task Manager was also reporting the underclocked speed. Many people suggested power settings (one of the first things I checked). I can assure you that they're all set to maximum performance, there is no throttling that is occuring at least in the menus that are visible in Windows. After a lot of googling, I found a guide to change a certain registry key - this "fixed" task manager, as Task Manager now shows my CPU at the full expected speed. However, HWInfo64 and my experience in games, and mining hashrate still shows that the CPU is still severely underperforming.
In device manager, I note that the processors are all showing with the same error message:
A driver (service) for this device has been disabled. An alternative driver may be providing this functionality. (Code 32)
I suspect that this may be related to the ratio / throttling issue. But I've been unable to get rid of this warning. Uninstalling the drivers for each processor and rebooting did nothing. I renamed the amdppm.sys file that they're using in System32 thinking maybe it's corrupted, but that hasn't helped either. AMD chipset drivers, which I've tried to download several times, always appear (bizarrely) to actually just be the display drivers in disguise, which I cannot understand, but regardless, I know that the CPU was running at full speed for the first day or two without any such drivers.
Please help. I am pulling my hair out in frustration with this. My new gaming rig is being massively neutered by something, which is turning my purchase in to a huge waste of money. I'm good with computers and have checked everything I can think of, and googled every term I can think is relevant, but I just cannot stop Windows from lowering the ratio!
