HPET is one of the available timers on a system. In competitive overclocking or benchmarking, it's often needed to activate it to avoid timing cheats that might interfere with other clocks. This is why I brought it up now. Recently, while setting up my streaming environment, performance seemed sluggish. After some testing earlier, I realized HPET was likely the culprit. Disabling it restored responsiveness. It's well known that HEPT can lead to performance issues in certain situations. I'm checking if other systems share this issue and adding it to my list of unusual performance concerns. Signs include elevated CPU kernel activity (check Task Manager) and unusually high GPU usage for simple tasks. For setup, as an admin, run: bcdedit /set useplatformclock true to enable, or /deletevalue to disable. Reboot if needed.

Man... I recall the days when TR launched and I had fresh Windows installed along with AI Suite 3, which activated HPET. The time it took to complete even a single task was... impressive. Fortunately, it was a learning moment that many experienced before.

I'm not very involved with hwbot anymore, especially after benchmate began testing beta. I shared some results to assist in the Country Cup, but none of the teams I joined were linked to BenchMate. It's just one option so far, not a complete solution yet.

I'm looking into my pet health status... I don't understand all the terms or whether the command was right. Is it active or inactive right now?

I verified your system settings recently. The value appears in the second section when it's active; otherwise, it's disabled. It seems you haven't manually enabled it before, so it likely isn't turned on. The only tool that commonly needed this feature was Ryzen Master, which required HPET to be enabled initially. I'm not sure if they've changed that requirement later.

I understand, I wasn't sure if I had ever activated it before, but it seems unlikely. I just needed to verify there was no issue before entering BIOS. That makes sense now... RYZEN MASTER didn’t really help me either. It worked only once at first, but after that, whenever I booted my PC, it would just stay on without any display or response, and this happened every time I used RM—even opening the program caused a crash. It’s possible my motherboard doesn’t support the feature or it wasn’t enabled properly (though it might be supported depending on the firmware). Thanks for the details!

I encountered issues with setting up and launching it before, so it doesn’t seem directly linked to HPET. For more information on the Ryzen aspect of HPET guidance, here’s the link: https://www.anandtech.com/show/12678/a-t...-results/3. In newer systems, enabling it at the BIOS level is often recommended, though the OS decides whether to use it (as mentioned in the first post). For the first generation, turning it off was suggested since having it active reduced performance. On Intel platforms, the model I struggled with was Skylake-X, possibly related. I haven’t noticed any change on my other machines when the setting was adjusted. This reminds me of a Dell i7-8700 that showed unusual slowdowns; I only found the issue during an OS restore and later fixed it. Now I’m considering HEPT might be involved again after previous benchmarking.

You seem to think the issue lies with the motherboard, while yours should work with RM. The MSI B450M you tried worked fine with the same parts, except for the motherboard quality—poor build led to instability and restarts. Your B350M is still functional and performs adequately.

Restart the operating system. It’s a poor solution, but it seems Windows and/or AMD programs were damaged, and I couldn’t resolve the issue otherwise.
