Dell 16GB DDR4-2666 SODIMM Laptop Memory (SNP821PJC/16G) – 2Rx8, 1.2V

Double a Dell laptop’s working memory with a Dell-specified 16GB module.

The Dell SNP821PJC/16G is a 16GB DDR4-2666 SODIMM for Dell Latitude, Precision, Inspiron, and OptiPlex Micro systems. It gives business users and IT teams a straightforward way to reach 16GB or 32GB, enough for Windows 11, collaboration apps, and data-heavy spreadsheets without slowdowns.

16GB Per Slot for Business Workloads

Business laptops that shipped with 8GB often run out of memory with Teams, Outlook, a browser, and Excel open together. Replacing an 8GB module with this 16GB stick, or installing two, removes that bottleneck.

As a dual-rank module, it lets the memory controller interleave between ranks, which supports steady throughput during multitasking.

It operates at 2666 MT/s and 1.2V, the native DDR4 speed of many Dell systems from the Intel 8th to 10th Gen era.

Path to 32GB

Two of these modules give 32GB in dual channel, a common standard for developer and analyst laptops in Dell fleets.

Consistent Spares for IT

Using Dell’s listed part number keeps repairs aligned with Dell documentation and simplifies inventory across multiple models.
