I replaced my defective motherboard that didnt want to work for a new one, an MSI B350 Tomahawk Plus, thanks to that I found out my gpu wasnt defective. But even with my old motherboard I couldnt run dual channel with my memory sticks its a kit of 2 8gb 2400mhz ddr4's, ive checked the compatability and it should be fine, but I still cant seem to run a dual channel, I would appreciate any advice to solve this problem.
