Hello, I'm new to this and trying to add RAM to my PC... I have an Asus Z170 Pro gaming board with two 4GB RAM sticks in DDR4 2800MHz CL16 slots. I just found two 8GB RAM sticks in DDR4 2133MHz CL15 slots for a great price, and I'm wondering if I can mix them together or if they won't work at all.

You're all set. It doesn't matter.

Not all claims hold up. Mixing components isn't enough—ram must move similarly, mismatched speeds can break things, or the system might not start.

If you install RAM sticks of various sizes, the system will not function optimally.

Could creating two dual channels work if you use the correct matching sticks in the appropriate slots?

It might affect the PC if you try them, but it depends on the compatibility. If they don’t work, staying with your current setup is safer. Switching to a 2x8 GB drive could be a good option if needed.

It's accurate. For configurations like 3x4 or 1x8, you'll still receive 16GB in dual-channel mode and 4GB in single-channel mode. In OP's scenario, every 24GB would function in dual-channel mode. They should operate (at least) to meet DDR4 requirements. But it's improbable all of them will perform consistently at 2800 CL16, so the actual speed remains uncertain. The only assured setting is the JEDEC standard: 2133 CL15 across all units.

It depends on what you already have; it might not be an improvement.

That's fascinating, I hadn't thought about how each bank of channels varied in size. Keep exploring!

It would require additional memory. Would you like more RAM? If unsure, always refer to the manual for your motherboard to confirm compatibility and specifications.
