Capacity 48GB

Rank 2Rx8

  • 48 GB capacity supports heavy workloads
  • DDR5-5600 speed moves data quickly
  • ECC protection corrects single-bit errors
  • CL46 latency enables fast data access
  • 10 V operation reduces power draw

48 GB DDR5-5600 ECC module

This 48 GB DDR5-5600 CL46 ECC unbuffered DIMM is built for servers and workstations that require error-correcting memory at JEDEC standard speeds. It operates at 1.10 V with a 2Rx8 organisation across 288 pins.

Suits ECC-capable platforms needing density

It suits administrators who need single-module density with ECC protection for virtualisation or database workloads. It is not for systems that only accept registered memory, nor for consumer boards that lack ECC support in the BIOS.

48 GB capacity with DDR5-5600 bandwidth

The module delivers 48 GB of capacity and 5600 MT/s transfer rate for memory-intensive services. Headroom ends when the platform requires registered DIMMs, higher frequencies, or lower latencies than CL46.

Questions about this item

Does my motherboard need a DDR5 slot and ECC support for this 48GB 288-pin module?

Yes, the module is a 288-pin DDR5 DIMM with ECC, so the board must provide a DDR5 slot and enable ECC in the BIOS.

Can I mix this CL46 2Rx8 kit with older DDR5 sticks running at different timings?

Mixing ranks and timings is possible but the system will run all modules at the slowest common speed and latency, so 46-45-45 becomes the baseline.

How do I confirm the 5600 MT/s speed and ECC function after installation?

Check the BIOS memory information or an OS tool such as dmidecode; it should report DDR5-5600, CL46, 1.10 V and ECC enabled.
