Review on 💾 G.Skill RipJaws SO-DIMM Series 32GB (2 x 16GB) 260-Pin DDR4 2400 CL16-16-16-39 1.20V SO-DIMM Memory Model F4-2400C16D-32GRS by Ryan Frawley

These RAM modules didn't work in my Dell XPS 9550 because they fail the built in diagnostics test in Dell Bios (F12) and crash windows after loading RAM. The accident exits the screen as an animated hodgepodge of horizontal lines. The seller was very good at accepting returns and I even ordered a second pair to see if there was a problem with the chips. Same problem. After further research, it turned out that the standard RAM on the 9550 has CL=15, while these sticks have CL=16.
