Alright, so I recently bought and installed two more sticks of RAM (8GB x 2 total 16GB) for my PC. they are the same brand, same clocking speeds. This extra set adds up to 32 GB of ram total in the PC currently. I go into my BIOS and set it up and seeing both channels having them set to the same clocking speeds, save and exit. Boot PC. However. once the PC boots and I run task manager. It says "slots used: 2 of 4" while hovering over it, it says "slot 1 / 2 Empty, slot 3 /4 8GB 2133MHz. No matter what I place into the bios and reboot. It comes up saying the same thing. 1/2 empty 3/4 in use. I am using an MSI B150 Gaming M3 Motherboard with an 1151 skylake chipset. Processor is an i5 6600K unclocked chip running on auto settings. OS Windows 10 Pro 64 bit. All I am looking to do is run both channels. If anyone knows why I am having this issue I'm open for feedback.
