32GB DDR4 2400MHz kit for Dell systems

This 32GB kit contains two 16GB DDR4 SO-DIMM modules rated at 2400MHz with CL17 timings and 1.2V operation. It is built for the Dell Inspiron 27 7775 All-in-One, Latitude 12 5280 and Latitude 12 7280. The unbuffered, non-ECC design matches the factory specification for those platforms.

Upgrade from lower capacity or slower DDR4

The kit replaces the original memory when the system shipped with less than 32GB total or with slower DDR4 speeds. The jump is worth it when the workload needs the full 32GB ceiling supported by these models and the 2400MHz data rate matches the platform maximum. Each module is a 2Rx8 rank configuration.

Verify slot count and maximum capacity first

Confirm the laptop or all-in-one has two SODIMM sockets and that the BIOS recognises 32GB as the upper limit. The package supplies two 260-pin sticks, so both slots will be occupied. No heat spreader is included, so ensure the chassis clearance accepts bare modules.

Questions about this item

Will the 260-pin SODIMM modules fit the two memory slots in my Dell Latitude 12 5280?

Yes, each 16 GB stick uses the standard 260-pin DDR4 SO-DIMM form factor that matches the two slots in the Latitude 12 5280 and 7280.

What is the correct way to seat the modules so the laptop recognises the full 32 GB?

Insert each stick at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click — skipping the click leaves the module loose and undetected.

When should I consider replacing these CL17 2400 MHz modules?

Replace them only if memory diagnostics report errors or the system becomes unstable; otherwise the non-ECC unbuffered DDR4 sticks have no wear-out schedule.
