16GB DDR5 ECC SODIMM for Samsung M426R2GA3BB0-CQK

This 16GB DDR5 4800 module is built as a direct replacement for the Samsung M426R2GA3BB0-CQK. It targets microserver, server and workstation users who need error-correcting memory in a compact SO-DIMM form factor. The unbuffered 1Rx8 design uses Samsung DRAM chips and runs at the standard 1.10V.

Build integration and slot requirements

The module fits a 262-pin DDR5 SO-DIMM slot and operates at PC5-38400 speed with CL40 latency. ECC capability adds data integrity for always-on workloads without requiring registered DIMM support. No heat spreader is fitted, so clearance is minimal and airflow from the chassis is sufficient.

Ideal for ECC SO-DIMM upgrades.

Buyers upgrading compatible Samsung-based microservers or NAS units will match the original spec exactly. Systems that accept only non-ECC memory, standard desktop UDIMM slots, or registered DIMMs cannot use this module. Check the system manual for supported memory seating and channel guidelines before ordering.

Questions about this item

Does the 1.1V voltage limit thermal headroom during continuous 4800 MHz operation?

The module runs at the standard 1.10V DDR5 voltage, so power draw and heat stay within normal SO-DIMM limits for all-day workloads.

How much heat does the 1Rx8 Samsung chipset produce without a spreader during sustained server loads?

Unbuffered ECC SODIMMs without a heat spreader rely on chassis airflow; the 1.10V rating keeps thermals manageable in typical microserver bays.

Must the host platform already support DDR5 4800 ECC unbuffered SO-DIMMs for this 262-pin module to function?

Yes — the system must accept DDR5 4800 ECC unbuffered 262-pin SO-DIMMs; consult the board manual to confirm compatibility.
