  • ECC protection prevents data errors in critical workloads
  • Unbuffered design reduces latency for responsive server operation
  • 32 GB dual-channel kit (2 × 16 GB) scales memory capacity efficiently
  • DDR4 2133 speed delivers 17 000 MB/s bandwidth for demanding applications
  • 260-pin SO-DIMM form factor fits compatible server and workstation slots

Capacity and purpose

This kit delivers 32GB of DDR4 server memory across two 16GB SO-DIMM modules. It targets administrators upgrading compatible laptops or compact servers that require ECC protection and unbuffered operation at 2133 MT/s.

Thermals and power

Standard DDR4 voltage keeps heat output modest during typical workloads, and the unbuffered design avoids the extra power draw of registered modules. Passive cooling in a properly ventilated chassis is sufficient for normal use.

Build and connectors

Each module uses a 260-pin SO-DIMM edge connector and a dual-rank 2Rx8 organisation. The form factor fits tight spaces, while ECC circuitry helps maintain data integrity in always-on environments.

Questions about this item

How do I install the 260-pin DDR4 SO-DIMM modules and what step is often missed?

Align the notch on each 16 GB module with the slot key, press firmly until both side clips click, then verify the system detects the full 32 GB at 2133 MT/s.

What maintenance or replacement will this ECC unbuffered kit need over time?

No routine maintenance is required; if a module fails, replace the faulty 16 GB SO-DIMM with an identical 2Rx8 DDR4 2133 ECC unbuffered part.

What limit appears first when the memory runs under sustained load?

The DDR4 2133 (PC4 17000) speed rating is the ceiling; bandwidth and latency cannot exceed this spec regardless of workload duration.
