I'm having a bitch of a time getting a new spool of WS2812b 12v RGB LEDs to work with my Asus ROG Strix B450 mobo. My steps thus far, which have yet to result in the strip lighting up at all:
1. Connected entire reel to Asus RGB cable, curious if it would light up. Ensured the orientation was (hopefully) correct, aligning arrow on Asus cable with red/12v wire on strip; connected Asus cable to mobo RGB header--no light.
2. Assuming the strip was too long to be powered by the header, I cut off a section approx. 48 cm.in length. Connected the string to both headers, and tried a calibration with the Aura sync software. Selected both combinations of headers in the program and mobo headers--no light.
3. I'd like to use a multimeter to test the strip in case it shipped faulty or I accidentally fried it, but aside from checking continuity of the 12v and ground rails, along with some probing of the LED pins themselves, I don't really know how to see if the strip is still functional.
4. For the hell of it, connected the short LED strip to a 12v Makita battery via the 12v and ground pins--no light.
I recently updated the BIOS to the most recent version (3003), have the newest version of Aura Sync, and can control the native lights on the board without issue.

Why are the wires switched around on the strip? Do I need to match them to the color orientation on the mobo header? I tried doing that with some wire extentions, but still nothing.
Please help!
