Hello everyone, I'm looking to upgrade my system memory, I currently have one kit 2x8gb cl16 3600mhz, I have 4 slot in my motherboard (msi mag mortar 550m wifi).

I found that CL16 kits are priced in the 90-100 euro range (Amazon germany) while the CL18 kits are priced in the 60-75 euro range. So I'm writing wondering if buying a CL18 kit would be downgrade in speed? And whether it would be noticeable or not?
