Laptop DDR4 ECC SODIMM

This 8 GB DDR4 2133 MHz module adds error-correcting memory to compatible laptops and mobile workstations. It targets users who need data integrity for professional workloads on portable systems. The unbuffered design keeps latency low for everyday multitasking.

260-pin SO-DIMM slot requirement

Installation requires a free DDR4 SO-DIMM socket that accepts 260-pin modules at 1.2 V. The single 8 GB stick leaves additional slots open for future capacity increases. Systems must support ECC unbuffered operation for the error-correction feature to function.

Standard 1.2 V operation

At the standard DDR4 voltage the module runs cool inside thin chassis designs. Low power draw helps preserve battery life during mobile use. Silent solid-state operation adds no audible noise to the system.

Questions about this item

How much capacity does a single 2Rx8 module provide before I hit the limit of one slot?

Each module delivers 8 GB of ECC DDR4 memory in a single 260-pin SO-DIMM, so one slot adds 8 GB.

What are the voltage and CAS latency figures that determine heat and power draw during continuous operation?

The module runs at the standard DDR4 voltage of 1.20 V with a CAS latency of CL15.

Which memory controller feature must my laptop or workstation already support for this ECC SODIMM to function?

The system must support unbuffered ECC DDR4 SO-DIMM operation; standard non-ECC controllers will not enable error correction.
