Okay, good, that processor supports up to 64 GB of RAM. It's odd that Crucial doesn't list 64 GB as max for this laptop, but mistakes do happen. Dell lists support for 2 X 32 GB DDR4 2666 MHz for maximum of 64 GB. I also found confirmation from some forum posts of users who successfully installed 64 GB in that laptop. This 64 GB kit from Crucial should work.  After you install the RAM and boot, the system may rest on a black screen, but leave it there for 30 minutes or so. Sometimes it takes a while for BIOS to recognize and accept new RAM.  Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
Computer currently has 32 GB ram and works fine.   Bought (2) Corsair Vengeance PC4-23400 (2933MHz) memory sticks.  Powered off the 5530.  Disconnected from dock. Opened unit and removed the (2) 16GB memory sticks.   Installed the new memory sticks.   Unit won't boot.  No nothing on the screen.   Tried each stick individually and same story. Am I missing something?   The Corsair is brand new. Firmware is up to date.   Would appreciate any ideas Thanks.
