Dell Latitude 5491 Vostro 7580 XPS 9570 upgrade

This 16 GB kit contains two 8 GB DDR4 SODIMM modules rated at 2666 MHz with CL19 timing. It is built for the Dell Latitude 14 (5491), Vostro 15 (7580) and XPS 15 (9570) and runs at the standard 1.2 V without ECC or buffering.

Replaces factory 8 GB or 4 GB sticks

The kit fills both SODIMM slots in the supported notebooks, doubling the common 8 GB factory configuration. The jump is worth it when the workload regularly exceeds the original capacity and the system can address the full 16 GB across two ranks.

Handles 16 GB across two slots

The notebooks accept a maximum of 32 GB, so this kit leaves one upgrade step open if 32 GB becomes necessary. It runs out when the platform limit of 32 GB is reached or when an application demands more than the two installed modules can provide.

Preguntas sobre este artículo

Will the 260-pin DDR4 SO-DIMM modules fit the two SODIMM slots in my Dell Latitude 14 5491?

Yes, the kit is built for the Latitude 14 5491, Vostro 15 7580 and XPS 15 9570, each of which uses two 260-pin DDR4 SO-DIMM sockets.

What is the correct way to seat the modules so they lock into the 260-pin slots?

Insert each stick at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the PCB.

When should I consider replacing one of the 8 GB sticks in this 16 GB kit?

Replace a module if the system fails to boot, shows repeated memory errors in diagnostics, or becomes unstable after the limited lifetime warranty period begins.
