March 9, 20215 yr Hello. As described already in my VR-related thread ( https://www.avsim.com/forums/forum/796-virtual-reality-vr-hardware-and-games/ ), performance of my 10900kf is pretty underwhelming. I don't know why, but due to whatever reason, it seems to be overclocked on as Windows basis: Task Manager shows me a base speed of 3.7 and a current speed of 4.9GHz. CPU-Z shows the same figures. Maybe that's due to the fact that MSI Dragon-Center was installed from the manufacturer. BIOS shows a clockspeed of only 3.7GHz, so somethings going on here on a WIN10 level. Today I've performed a PassMark CPU Test and attained a Mark of about 20.000. This seems to be well below average, as the average according PassMark is around 24.000. Furthermore: I've attained only 20.000 with a clock speed of 4.9Ghz, the comparitive values ( 24.000 ) are all related to the base clock of 3.7GHz. What's going on here? Any help / assistance would be highly appreciated. Thank's in advance and best regards, Toto
March 9, 20215 yr The BIOS will usually only show the default stock clock speed. Without overriding the default boost clock behavior, the CPU will overclock itself based on the number of cores that are loaded, and then only for a limited period of time. I'd start by overriding the boost clock (otherwise why buy a K-series CPU and a Z490 motherboard?) and get all the cores running at least at 5.0 GHz and then try again. The default boost behavior is more advertising puffery than actual performance enhancement, unless you are running an application that only needs max processing power in occasional short bursts (not even close to what a real-time simulation workload looks like).

March 9, 20215 yr Author Hello. Both CPU-Z and Speccy are showing multipliers of 49-50, thence the clockspeed of 4.9GHz. I think I have to labour a little bit on overclocking. What irritates me is the well below average performance of my CPU on the PassMark CPU-Mark Benchmark. Best regards, Toto

Yeah, I agree. "Tau" is only 57 seconds. Pretty pointless in my opinion.
