OWC 4GB DDR3L SODIMM for Dell XPS One 2720

This 4GB DDR3L 1600 CL11 module is built for the Dell XPS One 2720 all-in-one desktop. It runs at 1.35V with a 204-pin SODIMM form factor and JEDEC-standard timings. The single-rank 1Rx8 design installs without tools in the accessible memory slot.

Suits XPS One 2720 owners needing a single 4GB stick

Buyers who want more than 4GB of total memory should look elsewhere. Systems requiring ECC error correction or registered modules are not supported. This module does not fit standard laptops or desktops using different pin counts or voltages.

JEDEC DDR3L 1600 CL11 1.35V SODIMM specification

The module operates at PC3L-12800 speed with CAS latency 11 at 1.35 volts. Matching these exact parameters ensures the XPS One 2720 recognises the upgrade and runs stably. Any deviation in voltage, speed or pin layout will prevent the system from booting.

Questions about this item

How do I install this 204-pin SODIMM in my Dell XPS One 2720, and what step do people often miss?

Power off and unplug the all-in-one, remove the rear access panel, align the notch on the module with the slot key, press firmly until both side clips click, then replace the panel before powering on; the step most often missed is fully seating the module so both clips engage.

What maintenance or replacement will this 4GB DDR3L 1600 module need over time?

No scheduled maintenance is required; if the system later needs more capacity, replace the module with a higher-density DDR3L SODIMM of the same voltage and speed.

What limit appears first when this CL11 1.35V memory runs under sustained load?

The 4GB capacity is the first bottleneck; once the operating system exhausts physical RAM it swaps to storage, which slows responsiveness well before thermal or voltage limits are reached.
