I have a Samsung 4gb 2666Mhz ddr4 SODIMM memory installed (but working on 2400Mhz due to motherboard limitation). More info about this RAM here https://semiconductor.samsung.com/emea/dram/module/sodimm/m471a5244cb0-ctd/
The CL of the installed memory is 19.
I want to add another 4gb one but it is from a different brand (Crucial). I found these 2 in the market but I couldn't decide (since they also have a different organization(rank x organization): 1Rx8):
Crucial 4GB DDR4-2400 SODIMM CT4G4SFS824A
Technology DDR4, Density 4GB, Module type SODIMM, DIMM type Unbuffered, Voltage 1.2V, Speed DDR4-2400, CAS latency 17, Extended timings 17-17-17, PC4-19200
Crucial 4GB DDR4-2666 SODIMM CT4G4SFS8266
Technology DDR4, Density 4GB, Module type SODIMM, DIMM type Unbuffered, Voltage 1.2V, Speed DDR4-2666, CAS latency 19, Extended timings 19-19-19, PC4-21300
I wanna know if it is possible to mix RAMs of different brands. If it is possible, what points do I need to consider to choose the one to buy.
