Hi,
I recently bought a new motherboard, RAM and CPU.

  1. MOBO: ASUS TUF B360-PRO GAMING
  2. RAM: CRUCIAL BALLISTIX 16 GB 8 GB X 2 DDR4 2400 MHZ DIMM
The RAM will only work in A1+A2 Slots, showing the full 16GB in windows (HWinfo 64)
Both RAM sticks are bought as a single pack, but not part of the QVL sheet for the motherboard.
Both work individually and together in single channel.
Memtest is giving 0 errors
RAM is set to XMP in bios

After a lot of testing, i ended up returning the motherboard and RAM to the retailer, and bought:
  1. MOBO Asus rog strix h370-f gaming
  2. RAM: Corsair Vengeance RGB DDR4 2666MHz 16GB (8GB x2)
(this is on the QVL list for the motherboard) CMR16GX4M2A2666C16


I still get the exact same issue now.
I have updated the BIOS, and installed the stock cooler

Video of Dual channel boot: https://drive.google.com/open?id=1rCF3DEEXcFt51EMIE6wvZfOA4iq0q-5E

Full Specs:
MOBO Asus rog strix h370-f gaming
CPU: INTEL CORE I7-8700 3.20GHZ BOXED CPU with: Cooler Master Hyper 212 Plus & stock cooler
RAM: Corsair Vengeance RGB DDR4 2666MHz 16GB (8GB x2)
GPU: ASUS DUAL GEFORCE GTX 1070 OC 8GB
PSU: Fractal Design Newton R2 1000W PSU
Boot Drive: Intel® SSD 330 Series 180GB 2.5", 25nm

Edit: adding video of boot

Try manually instead, and try dual channel with manual settings. The settings will either be on the side of the module itself and might say something like 14-18-18-34 2T 1.35v or something like that. You then enter the values manually in the corresponding field in the bios. Save changes, reboot and see if it posts in dual channel.

I dont seem to have a manual setting. only AUTO or XMP.
when its set to XMP it displays the same timings as shown on the ram itself.
16-18-18-35
 
So leave it on Auto ( i think) and further down you have DRAM frequency and Dram Timing. Select the frequency you want, and enter the timings manually. See if it boosts at rated speed like that and of course in dual channel which is the goal here.

Exact same result as the video, goes into a boot loop with no POST. If i remove the RAM put into B2 it boots fine with these settings.
