Dell Latitude Laptop Memory

Memory upgrades for Dell Latitude business laptops — 3000, 5000 and Rugged Extreme series. Every module on this page is a non-ECC SODIMM matched to the exact Latitude model it ships for, so you are not cross-referencing part numbers against a Dell manual to find out whether a stick fits.

Latitude platforms are split across two memory generations. The 3420, 3520, 3440, 3540, 5430 and 5430 Rugged Extreme take DDR4-3200 (PC4-25600). The 5440 and 5540 are available in both DDR4-3200 and DDR5-4800 (PC5-38400) depending on build — check your system's existing module before ordering.
