Purpose-built ECC upgrade

This 16 GB DDR5 SODIMM adds error-correcting memory to compatible microservers, mobile workstations and NAS servers. The single-rank module installs in a standard 262-pin slot and runs at the JEDEC-standard 1.1 V. Systems must explicitly support ECC unbuffered DDR5 SO-DIMMs for the module to function.

Thermals and power

Operating at the nominal DDR5 voltage of 1.1 V keeps power draw low and heat output minimal without a spreader. The unbuffered design avoids the extra electrical load of registered modules. Typical laptop and microserver cooling handles the thermal load silently under normal workloads.

Decisive spec

ECC unbuffered operation is the single specification that determines compatibility; the module will not work in platforms that require non-ECC or registered memory. Verify that your system lists DDR5 ECC SODIMM support before purchasing.

Questions about this item

How do I install the 262-pin DDR5 SODIMM and what step do people get wrong?

Align the notch on the module with the slot key, insert at a slight angle, then press down evenly until the side clips click. The step often missed is pressing both ends simultaneously so the module seats fully in the 262-pin socket.

What maintenance or replacement will this 16GB ECC module need later?

No scheduled maintenance is required. If a memory error is logged, run a diagnostic to confirm the module is at fault, then replace the single 1Rx8 stick. Dust can be cleared with compressed air during routine system cleaning.

What limit appears first under sustained load with this CL40 1.1V module?

The JEDEC-standard 1.1V operating voltage and CL40 latency define the thermal and timing envelope. Under continuous heavy workloads the module will throttle to stay within its rated voltage and latency limits before any other constraint is reached.
