16 GB DDR4 ECC SO-DIMM for mobile workstations

This 16 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.20 V operation. Error-correcting code protects data integrity in professional workloads. The unbuffered 2Rx8 design fits 260-pin SO-DIMM slots found in compatible mobile workstations.

Unbuffered 260-pin layout with no heat spreader

The bare green PCB slides directly into SO-DIMM sockets without extra clearance concerns. ECC parity bits add reliability for long compute sessions while the 1.20 V rating keeps power draw low. Absence of a heat spreader suits tight chassis where taller modules would interfere with neighbouring components.

Replaces non-ECC or lower-capacity DDR4 SO-DIMMs

Upgrading from 8 GB or non-ECC sticks adds both capacity and error detection for memory-intensive tasks. The jump is worth it when applications demand data accuracy and multitasking headroom beyond standard laptop memory. Builders needing registered DIMMs or higher speeds should look elsewhere.

Questions about this item

Does the DDR4-2666 (PC4-21300) interface cap real-world bandwidth?

The module is rated at 2666 MHz with PC4-21300 bandwidth; actual throughput depends on the platform memory controller and channel configuration.

What physical slot and form factor does this 260-pin SO-DIMM require?

It fits a standard 260-pin DDR4 SO-DIMM socket and has no heat spreader, so it clears tight laptop or blade-server slots.

What is the correct installation step for this unbuffered ECC SO-DIMM?

Align the notch with the key in the slot, press firmly until the side clips click, and verify in BIOS that ECC is enabled for the 2Rx8 ranks.
