Compatible Dell XPS 15 9550 Upgrade

This 4 GB DDR4 SODIMM module is built for the Dell XPS 15 9550 laptop. It delivers a straightforward capacity increase for owners of that specific system. The single stick fits one of the two available slots and supports the platform's maximum of 32 GB total memory.

260-Pin Unbuffered Layout

The stick uses a standard 260-pin SO-DIMM edge connector with no heat spreader, keeping the profile low for tight laptop bays. Unbuffered, non-ECC organisation and a single-rank 1Rx8 layout mean it drops straight into the factory socket without configuration changes. One module ships in the package.

1.2 V Operation at 2133 MHz

Rated at DDR4 2133 (PC4-17000) with CL15 15-15-15 timings, the module runs at the JEDEC-standard 1.2 V. Low voltage and the absence of a spreader keep thermals modest inside the slim chassis. Power draw stays minimal during typical workloads, helping battery life and acoustic profile.

商品問答

What speed does the DDR4 2133 MHz SODIMM actually run at in the Dell XPS 15 9550?

The module is rated at DDR4 2133 (PC4 17000) and will operate at that speed if the laptop's memory controller supports it; otherwise it downclocks to the highest speed the platform allows.

Will the 260-pin SODIMM fit the Dell XPS 15 9550's memory slots?

Yes, the stick uses the standard 260-pin DDR4 SO-DIMM form factor that matches the two slots in the XPS 15 9550.

How do I install the module and what common mistake should I avoid?

Power off the laptop, open the bottom cover, align the notch on the 260-pin SODIMM with the slot key, insert at an angle and press down until the side clips click; the frequent error is not pushing firmly enough so the clips do not latch.
