Dell Latitude 3490 3590 5290 memory

This 8 GB DDR4 SODIMM is built for the Latitude 3490 3590 and 5290. It plugs into a 260 pin slot and runs at 2400 MHz with CL17 timing. The module is unbuffered non ECC and uses a 2Rx8 layout. It suits owners who need a single stick to fill one of two slots.

1.2 volt low power operation

At 1.2 V the stick draws little power and produces minimal heat. No heat spreader is fitted so airflow from the laptop fan cools the chips directly. Silent operation is assured because there are no moving parts. The low voltage helps preserve battery life during normal workloads.

Single stick simplifies upgrades

The package contains one 8 GB module so you can add capacity without removing an existing stick. Major brand chips are used but the exact chipset may vary. Buyers who want more storage or a matched pair for dual channel should order a second identical unit. Picture is for reference only and appearance may differ.

Questions about this item

How do I install this 260-pin SODIMM into my Latitude 3490, and what step is often missed?

Power off the laptop, remove the base cover, insert the module at an angle until the gold contacts disappear, then press down firmly until both side clips click — many users stop at the angle and leave it unlatched.

Will this CM1024642400SO module need replacement or maintenance during its service life?

No routine maintenance is required; the unbuffered DDR4 stick has no heat spreader or moving parts, and the limited lifetime warranty covers manufacturing defects, so replacement is only needed if a fault develops.

What limit appears first when this 2400 MHz CL17 memory runs under sustained load?

The CL17 latency at 1.2 V is the primary constraint; bandwidth caps at the DDR4-2400 rating before thermal or voltage limits become a factor in these Latitude models.
