Question I5 7600K - Low Cinebench

[Jwalkaflocka3]

My i5 7600k @ stock clocks is only getting around 630-640 in Cinebench. This seems rather low and am not sure what could be causing this.

Specs : i5 7600K @ 3.8ghz
Mobo : Gigabyte Z270P-D3
GPU : MSI Gtx 1080 gaming X
Ram: 16GB 2400Mhz Corsair.
SSD : Samsung 860 Evo

I have made sure there is nothing taking up CPU usage, about 15% of my memory is in use on Idle to something called "Antimalware service executable" but as far as I remember thats windows defender so I can't really do anything about that right?

UPDATE after some further testing I have discovered that the chip is boosting to 4GHZ on all 4 cores under complete load instead of 4.2. Im sure this is a reason for why my 7600k is performing worse then others. But how do I unlock its ability to fully boost to 4.2 as advertised?

4.2 is for single core max. 4ghz for all core sound correct

what the cpu temp and usage during the test?
fresh os install for the system?
what OS?

Highest core temp was 55 degrees Celsius on core #2.

I just recently upgraded from a HDD to an SSD so yes windows has recently been installed.

I am running windows 10 Home.

As you are on a Z270 board, Intel's XTU (Extreme Tuning Utility) would easily let you specify higher clock speeds (in 100 MHz increments)under a 1,2,3, or 4 core load to whatever clock speed you think your CPU is capable of...(you may also manipulate core voltage, but, most like to avoid that, as it raises temperature much more than an extra 100-200 MHz...)

If the computer crashes for any reason, the XTU-induced OC is effectlvely removed, defaulting to all stock settings, the next boot...

I went into the utility and did what you said and let my cpu run at 4.4 on all 4 cores and I saw an increase in cinebench up to 685! The max core temp I saw on any core was 65. Do you think I need to adjust the voltage or am i alright leaving it. Thanks

I managed to get 703! With stable core temps (70 c max) running at 4.5! If no problems are encountered I think Ill run it like this.
