Compatible Dell Laptop Memory

This 8 GB DDR4 SO-DIMM is built for the Dell Inspiron 15 5577, Precision 5520 and XPS 15 9560. It targets owners of those specific models who need a straightforward capacity increase. Buyers with other Dell lines or non-Dell notebooks should verify their exact part number before ordering.

260-Pin DDR4 2400 Form Factor

The module uses the 260-pin SO-DIMM interface and runs at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V. A laptop that requires a different pin count, voltage or DDR generation will not accept this stick. The single 8 GB rank fills one of the two available slots in the supported systems.

Simple Slot Installation

Installation consists of opening the service hatch, aligning the notch on the 260-pin edge connector and pressing the module until the retention clips engage. The most common issue is inserting the stick at an angle or not seating it fully, which leaves the system unbootable until reseated.

Questions about this item

Will the 2400 MHz DDR4 speed actually run at that frequency in my Dell Inspiron 15 5577?

The module is rated at 2400 MHz (PC4 19200), but the laptop's memory controller will set the final operating speed, which may be lower depending on the specific system configuration.

Is this 260-pin SODIMM the correct physical interface for the Precision 5520?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the memory slot specification for the Precision Mobile Workstation 5520.

Does the 8 GB stick fit the single slot upgrade path for the XPS 15 9560?

The XPS 15 9560 supports up to 32 GB across two sockets, so this single 8 GB unbuffered module can be installed in an available slot.
