Ziggg Posted November 22, 2020 Share Posted November 22, 2020 Good afternoon. Please tell me what could be the problem. Memory performance degrades over time in a single session. After reboot, it repeats again. No overclocking. BIOS parameters in AUTO + XMP. Note that tests in, for example, 7zip and LinX do not record performance drops. Thanks.

I also notice the CPU frequency and uncore frequency is different for the two memory benchmarks, and the CPU frequency is different for the GPGPU benchmarks.

Modules without sensors. I measure with a thermocouple in Zalman Z9 Plus. There is such a thing. It looks like AIDA64 takes their values according to its algorithm. In Hwinfo 4500 are stable for all processor cores and 4300 with uncore under load. Quote Link to comment Share on other sites More sharing options...
Arctucas Posted November 24, 2020 Share Posted November 24, 2020 So, the processor speed is remaining constant? If BIOS setting are at DEFAULT, does that include Speedstep or various C-states being active? Perhaps Windows Power Plan is downclocking processor? Strange that AIDA64 would show speed different from actual, but only after some time has passed. Quote Link to comment Share on other sites More sharing options...

When running in Windows sandbox, the result is always normal. Quote Link to comment Share on other sites More sharing options...
Ziggg Posted November 29, 2020 Author Share Posted November 29, 2020 After reinstall the system, everything became ok. No matter the time. Quote Link to comment Share on other sites More sharing options...

Ziggg Posted December 6, 2020 Author Share Posted December 6, 2020 Everything repeated itself. As it turned out, reinstalling the OS was not required to fix the problems. It is enough to disable Windows Sandbox in the settings OS. Quote Link to comment Share on other sites More sharing options...
