" rel="nofollow - I'm trying to find any info about Performance Mode/Easy OC Header (PM EO) found on my Z370.
Killer Sli motherboard. For what purpose can it be used?
Manual provides just header pinout.
Do I need specific device or it is possible to use simple button and LED connected?

I believe it is used to enable specific OC items enabled in BIOS with just push of a button.
My board does not have it but has one click OC in BIOS and think the header allows doing same without reboot to BIOS, but could be wrong.
The documentation for some things are on the driver CD included in motherboard box, and not in the paper manual or manual thru download from Asrock.
Yes: You can use a simple button and LED (like from salvage off an old case, HD led and reset button)

Thanks for the answer.
Checked CD - nothing concerning Easy OC Header, drivers\pdfs - the same as at MoBo support page. CD is common for Z370 Pro4/KILLER SLI (mine mobo)/Extreme4.
Asked support and still waiting for the answer for few days. Wondering but it seems nobody at all knows what this thing does.
Happy computing with yours Z370 Pro4/I7-8700K build!
