16GB DDR5 4800MHz SODIMM for Dell laptops

This 16GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It uses a 262-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The stick is built as a direct replacement for Dell part numbers AB949334 and SNPVNY72C/16G.

Major-brand chips on unbuffered PCB

Major-brand chips are used on the unbuffered PCB to deliver dependable performance in daily workloads. The 262-pin edge connector fits standard DDR5 SO-DIMM slots found in compatible laptops and all-in-one systems. Installation requires no additional tools beyond normal memory-slot access.

Upgrade from lower-capacity or slower DDR5

Replacing a smaller module or a slower DDR5 stick adds headroom for multitasking and reduces memory pressure in demanding applications. The jump is worthwhile when the system supports DDR5 4800 and has a free slot or can swap the existing module. Verify your platform’s supported specifications before purchase.

Questions about this item

What throughput does the PC5-38400 rating on this DDR5 SODIMM cap at in practice?

The PC5-38400 designation means the module is rated for 4800 MT/s, which is the maximum data rate this stick will run at in your system.

Will the 262-pin DDR5 SO-DIMM fit my Dell laptop that uses part numbers AB949334 or SNPVNY72C/16G?

Yes, the 262-pin DDR5 SO-DIMM form factor matches the Dell AB949334 and SNPVNY72C/16G modules, so it installs in the same memory slot.

How do I install this 1Rx8 unbuffered DDR5 module, and what step do people often miss?

Power off the laptop, disconnect the battery if possible, open the memory compartment, insert the module at an angle until the gold contacts are hidden, then press down firmly until both side clips click — the step many miss is pressing down hard enough to engage both clips.
