Asrock z370 Extreme4 Stutter, Bad frametime spikes - i7 8700k, GTX 1070

Recently I bought new parts for my build, together with the 8700k I got:

EVGA GeForce GTX1070 FTW Gaming 8GB
G.Skill Ripjaws 3200Mhz 2x8GB
ASRock Z370 Extreme4
Scythe Mugen5 PCGH Edition
Corsair CS650M PSU

Only XMP setting and standard turbo OC (max 4,6 Ghz) in BIOS

Temps stay pretty low, but when I try to run programs like Chrome or a map from a game then the temps jump +10 - +20 in HWmonitor and Afterburner. Temps stay there for 1 second and then drop down to normal again.

Example between idle and starting chrome:

Ingame example (Quake Champions: Maxed) and launching chrome in the background. Loading a new map within the game gives the same results:

Afaik temps shouldnt rise 10 - 20 degrees for 1 second for launching common applications, so im wondering if there something set wrong.

Voltage seems to go fairly high on some clocks (1.350) aswell.

Thanks in advance.

rsky,

On behalf of Tom's Moderator Team, welcome aboard!

I just finished writing this in two other Threads when I saw yours; it's from the following Thread: Possible issue with Core i7 8700K Clock speed fluctuation on Idle - http://www.tomshardware.com/answers/id-3722730/issue-core-8700k-clock-speed-fluctuation-idle.html


I hope that clarifies the nature of the problem. Also, we have a Guide you should read:

Once again, welcome aboard!

Thanks for the post, I have changed a few things about my setup and it seems that it doesnt get as hot anymore.

However I am having an entirely different issue now. With games I get really bad frametime spikes. These happen in Windows aswell sometimes, however way less noticeable. Things I tried to avoid this:

-Reinstall Windows 10 (twice)
-Install motherboard drivers
-Flash motherboard to new version
-Update firmware on SSD
-Change SATA cables
-Disable XMP
-Remove NVIDIA drivers and reinstall latest
-Use specific settings in NVIDIA control panel
-Test CPU and RAM under stress
-Default settings motherboard

I am completely out of things to try, and this issue was not there with my older motherboard / cpu. Here is an image to show how inconsistent it is:

Is there a posibility that the PSU is defect?

Really hoping some has a solution to this, as im almost tempted to send everything back at this point. Its a bit strange that better hardware performs worse.
