System-specific DDR5 SODIMM for Dell Precision

This OWC module is a 16 GB DDR5 4800 CL40 1Rx8 SODIMM built to 262-pin 1.1 V JEDEC specification. It is validated for Precision 3470, 3571, 3581, 5570 and 5770 workstations. The part replaces Dell AB949334, AC258275, SNPCYXXPC/16G and SNPVNY72C/16G modules. Installation is a standard DIY procedure.

Who this suits and who should look elsewhere

Buyers upgrading a listed Precision laptop or all-in-one with a single 16 GB stick will match the factory memory profile exactly. Builders needing ECC, registered DIMMs, higher capacities per slot or a different DDR generation cannot use this module. Systems outside the five Precision models listed have not been qualified by the manufacturer.

Deciding specification — 262-pin DDR5 4800 SODIMM

The 262-pin DDR5 4800 interface is the single factor that determines fit; only platforms wired for this exact pin-out and speed will accept the module. Matching the 1.1 V JEDEC voltage and CL40 timing ensures the memory runs at the rated data rate without manual configuration.

Questions about this item

How much power does the 1.1V DDR5 4800 SODIMM draw during continuous all-day workloads?

The module runs at the JEDEC-standard 1.1 V, which keeps power draw low for a 16 GB DDR5 SODIMM during sustained use.

Which Dell Precision models must the laptop already be for this 262-pin CL40 module to work?

It is validated for Precision 3470, 3571, 3581, 5570 and 5770; the system must be one of those models.

Will this non-ECC 1Rx8 stick run alongside the original Dell memory in a Precision 5570 without timing conflicts?

Yes — it matches the factory DDR5 4800 CL40 1.1 V spec, so it operates at the same speed and latency as the OEM modules.
