Underwhelming performance of 10900kf

Post by Highflyer747 »

Hello.

As described already in my VR-related thread ( https://www.avsim.com/forums/forum/796- ... 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

If you yourself did not overclock this, then you are probably running at 3.7 GHz.

For overclocking start with consulting your motherboard manual.

Hello Jorgen.

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

Here is a good place to start the overclocking "game": http://gex.flight1.net/forumimages/Over ... Series.pdf

Your processor is designed to get high clock rates on few cores over short time, explained e.g. here.
If your BIOS settings are according to Intel defaults, these high clock frequencies are kept just for a minute.
The fewer cores are used, the higher frequencies.
Intel default means gradual frequencies: some few cores run very high, the other cores run lower, but you cannot decide which application/thread runs with what frequency at a specific point in time.
So maybe a first trial would be the AFFINITYMASK setting to reduce the number of cores that Prepar3d uses, so these fewer cores gain higher frequencies.
