A-Tech 48GB DDR5 5600 ECC SODIMM 2Rx8 Server RAM

SKU CH-EEFD-WZJGJ

48GB DDR5 5600 ECC SODIMM with 2Rx8 organisation, 1.1V operation and CL40 latency for microserver upgrades

  • Capacity48GB
  • Type262-Pin DDR5 SO-DIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS Latency40
  • Voltage1.10V
  • ECCYes
  • 48GB capacity lets you run larger workloads in a single slot
  • DDR5 5600 speed delivers 44800 MT/s bandwidth for responsive multitasking
  • ECC unbuffered design detects and corrects memory errors automatically
  • 2Rx8 dual-rank organisation increases density without adding modules
  • 10V standard voltage keeps power draw low in microserver environments

Capacity and form factor

This is a single 48GB DDR5 SODIMM built to the 262-pin SO-DIMM standard. It delivers PC5-44800 speed at 5600 MHz with a CAS latency of 40 and operates at the standard 1.10V. The module uses a 2Rx8 rank configuration and includes on-die ECC for data integrity.

Suitable systems and limits

It fits microserver, server and workstation platforms that accept unbuffered ECC DDR5 SODIMMs and can address a 48GB rank. Builders whose boards require registered DIMMs, non-ECC memory, or a different pin count should look elsewhere. The lack of a heat spreader also means it relies on chassis airflow for cooling.

Build integration

The stick slots directly into any compatible 262-pin DDR5 SO-DIMM socket without extra power cables or adapters. Its unbuffered design keeps the memory controller simple, while ECC protects against single-bit errors in critical workloads. The 1.10V operation matches the DDR5 baseline, so no voltage tuning is required.

Questions about this item

My system only has 262-pin DDR5 SO-DIMM slots — will this 48 GB module fit?

Yes, the module is a 262-pin DDR5 SO-DIMM, so it physically fits any slot built for that form factor.

Can I keep my current DDR5-4800 ECC SODIMMs installed and add this DDR5-5600 2Rx8 module?

The system will run all modules at the lowest common speed, so the 5600 MT/s module will operate at 4800 MT/s alongside your existing memory.

How can I verify the module is running at DDR5-5600 with ECC active after installation?

Check the BIOS memory information or use a tool like CPU-Z; it should show 5600 MT/s, CL40, 1.10 V and ECC enabled for the new module.
