Capacity and form factor

This is an 8 GB DDR4 laptop module in the 260-pin SO-DIMM form factor. It targets owners of compatible Supermicro notebooks or compact systems who need a straightforward memory increase. The stick is unbuffered and non-ECC, matching the standard slot layout used in many thin-and-light designs.

Speed and voltage headroom

Rated at 2666 MHz with a CL19 latency, the module runs at the standard 1.20 V DDR4 voltage. It will handle everyday multitasking, browser tabs and office workloads without bottlenecking the memory subsystem. Heavier tasks such as large dataset processing or virtual machines may exceed the single 8 GB capacity before the speed ceiling becomes a factor.

Certified Supermicro part number

The decisive specification is the Supermicro certified part number MEM-DR480L-SL01-SO26, which corresponds to the Samsung M471A1K43CB1-CTD module. Only systems that explicitly qualify this exact part number are guaranteed to accept it; other laptops may reject the module or run it at a lower speed.

Questions about this item

Will this 2666 MHz DDR4 SODIMM work with my existing DDR4 laptop memory?

This module runs at 2666 MHz with CL19 latency and 1.2V. When paired with other DDR4 SODIMMs the system will operate at the speed of the slowest installed module.

How can I confirm the module is running at 2666 MHz after installation?

Check the memory speed in your system BIOS or use a tool such as CPU-Z; it should report 2666 MHz (PC4-21300) with CL19 timings at 1.2V.

Does the package contain only the 8GB SODIMM or are any extra parts included?

The box contains the single 8GB 260-pin DDR4 SODIMM (Samsung M471A1K43CB1-CTD). No heat spreader, cables or tools are supplied.
