[SOLVED] SOLVED- new build: intel core i5-9400f downclocked

[antonis mark]

I successfully booted up my new build but my CPU is having a problem: its downclocked from max to somewhere 2.6 GHZ (the advertised max turbo frequency is 4.10 GHz) much lower than my old i5-2400 with max (and current) turbo frequency at 3.4 GHz in, an app called "HWinfo" reported that the turbo feature is on on the CPU (the new one). Do you know if its wrong settings or a bad MBO or CPU

did you do a fresh os install?

I have the build in the link: https://pcpartpicker.com/list/9hYxNP
I wonder if its the ram since its 2400 MHz instead of 2666

check the cpu temp
that not a cpu cooler you want to use on a anything new.

1.ok I will buy an aftermarket cooler in the next months when I got the money
2. after it got started I check the temperature , it was somewhere 30 celsius to 45 celsius it wasn't running that hot

check the temp when it under load.

check the temp when it under load.

well that may take a week, I need first a proper graphics card and also to transfer my data and games to the new computer but I will check once I got it, by the way, do you know any application that intentionally loads the CPU for a long time for testing? (of course I don't want viruses or trojan)

ts downclocked from max to somewhere 2.6 GHZ

where did you see this then? if it not doing anything. it wouldn't turbo much

I saw it in the task manager, processes tab

 

[rgd1101]

latest window? latest HWinfo?
task manger is not something I would use.

what the motherboard? latest bios?

 

[antonis mark]

motherboard : Asrock Z4 pro with factory implemented bios

 

[rgd1101]

try update the bios

 

[antonis mark]

i will try this Wednesday

EDIT: I was stupid. I thought at first that the clock speed was for the entire processor. now I know that clock speed is per core, after doing the math I found that this processor works as intended. I check the clock speed again it was 2.9 GHz not 2.6

 

[rgd1101]

what? all 4 cores can do 2.9ghz based and if with 1 active core up to 4.1ghz
