8 GB DDR4 SO-DIMM for Dell Latitude

This 8 GB DDR4 2400 MHz module is built for Dell Latitude 3490, 3590 and 5290 laptops. It uses a 260-pin SO-DIMM form factor with CL17 timing and 1.2 V operation. The unbuffered, non-ECC design suits standard business workloads and general multitasking. Buyers needing ECC error correction or registered signal buffering should look elsewhere.

Thermals, noise and power in daily use

Running at 1.2 V, the stick draws minimal power and produces no audible noise. Without a heat spreader, it relies on the laptop’s internal airflow for cooling. Typical office tasks keep temperatures well within normal SO-DIMM limits. Heavy sustained loads in thin chassis may warm the module more than a spreader-equipped alternative.

What the bundle changes for you

The package contains a single memory stick, giving you one 8 GB upgrade or replacement unit. Compatibility is guaranteed for the listed Latitude models, reducing the risk of POST failures. No software, drivers or additional hardware are included. The limited lifetime warranty from Computer Memory Solutions covers manufacturing defects only.

Questions about this item

How do I install this 260-pin DDR4 SO-DIMM in a Dell Latitude 3490 and which step is often missed?

Power off, unplug, remove the battery, open the memory door, insert the module at an angle until the gold contacts are hidden, then press down until both side clips click — the step most people miss is reattaching the battery before closing the case.

What maintenance or replacement will this CL17 1.2V module need over time?

No scheduled maintenance is required; if errors appear later, run a memory diagnostic and replace the stick if it fails, otherwise it runs for the system's life.

What limit appears first when this 2Rx8 2400 MHz kit runs sustained workloads?

The platform caps total memory at 32 GB across two sockets, so capacity is the first ceiling you hit before bandwidth or thermal limits.
