Dell Latitude 15 5570 compatible DDR4 SO-DIMM

This 4 GB DDR4 2133 CL15 module is built to match the memory slot specification of the Dell Latitude 15 5000 (E5570). It uses a 260-pin SO-DIMM form factor and runs at 1.2 V unbuffered without ECC. The single 1Rx8 stick installs directly into one of the two available sockets.

Upgrade path for single-slot expansion

Owners of the E5570 who have one free slot or want to replace a smaller module can add this 4 GB stick. The system maximum is 16 GB across two sockets, so a second identical module would be needed to reach that ceiling. Builders working on any other laptop or desktop platform should look for memory validated for their specific model.

2133 MHz DDR4 speed rating

The module operates at DDR4 2133 (PC4 17000) with CL15 15-15-15 timing. If the target system requires a different DDR4 speed grade or a different CAS latency, this part will not meet that requirement.

Questions about this item

Does this 260-pin SO-DIMM fit the Dell Latitude 15 5000 (E5570) memory slots?

Yes, the module is built to the 260-pin DDR4 SO-DIMM form factor used by the Latitude 15 5000 (E5570) and is guaranteed compatible by the manufacturer.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click; the step often missed is pressing hard enough to engage both clips fully.

Will this stick ever need a firmware update or scheduled replacement?

No, DDR4 memory has no firmware and no moving parts; it runs at 1.2 V with CL15 timing for the life of the system unless a physical fault occurs.
