4GB DDR4 2400MHz SODIMM for Dell Latitude

This 4GB DDR4 2400MHz SODIMM is a system-specific memory upgrade built for Dell Latitude 14 5480, 5490, 5495 and 7490 notebooks. It runs at 1.2V with CL17 timing in a 260-pin unbuffered non-ECC layout. The single-module kit installs directly into an available slot.

Suits owners of listed Latitude models adding one

Buyers who need ECC error correction or registered buffering should look elsewhere, as this stick provides neither. Systems already filled to the 32GB maximum across both sockets will not accept another module. The 2Rx8 rank configuration may not match every factory layout, so verify the existing stick before ordering.

2400MHz DDR4 speed with CL17 timing

The module operates at DDR4 2400 (PC4 19200) with 17-17-17 latency at 1.2V. This speed and timing combination determines whether the memory will run at its rated frequency or downclock to match slower installed modules. Matching these figures to the system's current memory is the single specification that decides fit.

Questions about this item

What speed and bandwidth does the DDR4 2400 SODIMM deliver?

The module runs at 2400 MHz with a PC4 19200 rating, so the practical throughput ceiling is the DDR4 2400 standard itself.

Which physical slot and pin count does the CM512642400SO require?

It uses a 260-pin SO-DIMM slot, the standard DDR4 SODIMM form factor for the listed Dell Latitude models.

How is the stick seated in the Latitude 5480, 5490, 5495 or 7490, and what step is often missed?

Slide the module into the slot until the gold contacts are no longer visible, then press down evenly until the side retention clips snap into place — skipping the final press leaves the stick unlatched.
