I have a MSI B350M PRO-VDH AM4 AMD B350 SATA 6Gb/s USB 3.1 HDMI Micro ATX AMD Motherboard and want to use G.SKILL Ripjaws 4 Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 and CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000. I had the rip jaw in slots 2 & 4 and that worked. Plugged the CORSAIR into slots 1 and 3 but it would only register that I had 16Gb of RAM and not 32. What should I do to make sure I get 32Gb of ram?

the BIOS can see them both, it just wont add up to the 32Gb. Just says 16Gb still
