What is the LED_DEMO header on gigabyte z170x-gaming 7 MB?

As the title states, I dont know what the header is for. it's a 2pin header. (Photo for refrence)
It may be a simple thing but i can't find anything in the motherboards manual or on the internet.

An LED uses two pins for power, so it's probably for adding LED strips or something, and controlling them (on/off, maybe brightness) with software.

 

This could be entirely wrong, and it could be a badly labelled 'case open'/NIC led header or something.

It can literally be anything. From pure power (ground and 12v) to power a led strip and potentially adjust brightness through pwm, to a i2c data pair (to talk to programmable leds) or maybe it's a header for a bluetooth/infrared/radio remote control...

 

If you have a multimeter around, you could check using the continuity function to see if those pins are connected to ground or some voltage rail... more than that maybe check bios or check manuals from other motherboards in the series with that connector ..

It's something to do with the audio's LED.

The socket has extra pins, which help with memory and cache overclocking. Without the extra pins and the switch in position 2, the cache cannot be overclocked over 4GHz, and the memory might have trouble hitting 3200MHz. GIGABYTE did upgrade the audio on the motherboard, and while RGBs light up the audio divide, there is an "LED DEMO" header which could output a signal that modders might be able to utilize.

I have found something like this http://www.ebay.com/itm/20Kits-Mini-Micro-JST-2-0-PH-2-Pin-Connector-plug-Male-with-150MM-cable-female-/191841761948?hash=item2caaa8fa9c:g:iGAAAOSwud1XAlqS

If i solder one of the female connectors to a LED strip, will it get power from the motherboard ?

I saw true purpose of this connector.
If you want to show your LED's without connection all stuff (CPU, MEMORY, PSU) and turning in on. (For demonstration only)
I saw that applying power to it will cause mother board LED's to show demo effect.
