Dell 14, 15 & 16 Laptop, All-in-One, Slim & Tower Memory

Memory upgrades for Dell's 2025–26 consumer computers, sold under the Dell name: 25 listings, each matched to Dell's published specification for that model.

• Dell 14, 15 and 16 laptops (16 listings, SODIMM): mostly DDR5 (14 D14260 Laptop, 15 D15260 Laptop and 16 DC16255 Laptop). The Dell 15 DC15250 takes DDR4 or DDR5 depending on the processor, so it has two listings; the Dell 15 DC15255 has a slot only on Ryzen 5 7530U and Ryzen 7 7730U configurations.
• Dell 24 and 27 All-in-One (4 listings, DDR5 SODIMM): 24 All-in-One EC24260 and 27 All-in-One EC27260 and the EC24250 and EC27250.
• Dell Slim and Tower desktops (5 listings).

Slim and Tower: SODIMM or UDIMM?

The memory type depends on the exact model. The Dell Tower ECT1250, Dell Slim ECS1250 and Tower Plus EBT2250 take full-size UDIMM modules; the Dell Tower DT1265 and Dell Slim DS1265 take laptop-size SODIMM modules. The model number is on the system label.

Not listed: the Dell 14S and 16S, Dell 14 and 16 Plus and the Dell 14 and 16 Premium, whose memory is built into the processor package or soldered to the system board.

Not sure of your model? The model name and number are on the label on the bottom of a laptop or on the back or side of a desktop, and the Service Tag lookup at Dell Support shows the original configuration, including whether the memory is in a slot or on the system board. Each listing is matched to Dell's published memory specification for that model: memory type, form factor, speed, slot count and maximum capacity.
