Capacity and Form Factor

This 16 GB DDR4 module uses the 260-pin SO-DIMM form factor designed for laptop memory slots. It operates at 2666 MHz with a CAS latency of CL19 and runs at the standard 1.20 V. The stick is unbuffered and non-ECC.

Who This Suits

Buyers upgrading a compatible Supermicro system that supports DDR4 2666 SO-DIMM memory will find this module validated for those platforms. Builders who need ECC error correction, registered buffering, or a different voltage should look at other modules.

Deciding Specification

The Supermicro certified part number MEM-DR416L-SL01-SO26 confirms this module has been qualified for specific Supermicro platforms. Verify your system’s supported memory specifications against this part number before purchase to ensure compatibility.

Questions about this item

Will the 260-pin DDR4 SODIMM need any firmware updates or periodic reseating after installation?

No firmware updates or scheduled reseating are required; the module installs once and runs without further maintenance.

What electrical or thermal ceiling stops the 1.20 V CL19 stick from running faster under continuous load?

The JEDEC 1.20 V specification and CL19 timing define the maximum stable speed; sustained operation cannot exceed the rated 2666 MT/s.

How much heat and fan noise does the 16 GB unbuffered module add when the laptop runs all day?

Without a heat spreader the module draws standard 1.20 V DDR4 power, adding minimal heat and no audible noise to the system.
