What this module does and who needs it

This 4 GB DDR4 SO-DIMM upgrades Dell Latitude 12 (E7270), Latitude 13 (3379) and Latitude 14 (E7470) laptops. It suits owners who want extra memory for everyday multitasking on those specific models.

DDR4 2400 SO-DIMM practical limits

The stick runs at 2400 MHz with CL17 timing at 1.2 V. Each notebook accepts two slots up to 16 GB total, so a single 4 GB module leaves one slot free but cannot exceed the platform ceiling.

Installation notes and common pitfalls

The 260-pin unbuffered design drops straight into the SODIMM slot without tools. Buyers who need more than 16 GB or who own a different Dell series will find this module incompatible.

Questions about this item

Should I buy a single 4 GB stick or two sticks for my Dell Latitude?

Each Latitude 12 E7270, 13 3379 and 14 E7470 has two slots and supports up to 16 GB. A single 4 GB module leaves the second slot free for an identical stick later, giving 8 GB in dual-channel mode.

What does the 2400 MHz rating deliver in daily use on these Latitudes?

The modules run at DDR4 2400 with CL17 17-17-17 timings at 1.2 V. On the listed Latitudes this provides the standard memory bandwidth for the platform, improving multitasking and application responsiveness over slower DDR4.

Will this 260-pin DDR4 SO-DIMM fit and run at the advertised speed in my Latitude?

Yes. The stick is a 260-pin unbuffered non-ECC DDR4 SO-DIMM rated at 2400 MHz (PC4 19200). The Latitude 12 E7270, 13 3379 and 14 E7470 all accept this exact form factor and will operate it at its rated speed.
