Capacity 64GB (4 x 16GB)

  • 64 GB capacity across four 16 GB modules for high-density server workloads
  • DDR5 4800 speed with CL40 latency accelerates data throughput
  • ECC Registered RDIMM design detects and corrects memory errors automatically
  • Single-rank 1Rx8 organisation enables quad-channel bandwidth on compatible platforms
  • 1 V DDR5 standard voltage reduces power draw per module

Server DDR5 64GB kit

This A-Tech kit provides 64GB of DDR5 server memory across four 16GB registered DIMMs. It is built for servers and workstations that require ECC registered modules. Desktop and laptop systems cannot use these DIMMs.

Quad-channel registered DIMMs

The four modules form a quad-channel kit for platforms that support DDR5 registered memory. Each DIMM uses a 288-pin interface and operates at the standard 1.1V. The registered buffer and ECC function reduce the electrical load on the memory controller and correct single-bit errors.

4800MHz CL40 capacity

Running at DDR5 4800 with CL40 latency, the kit delivers 64GB of error-correcting capacity for virtualization, databases and compute workloads. The single-rank x8 organisation helps keep signal integrity high. Systems that need more than 64GB or faster speeds will require additional modules or a higher-speed specification.

Questions about this item

What sustained-use limit appears first with these CL40 1.10 V modules?

The single-rank 1Rx8 organisation and CL40 latency define the timing boundary under continuous load.

How much heat and noise do four 1.10 V registered DIMMs add to a server running all day?

Each 16 GB module runs at standard 1.10 V DDR5 voltage with no active cooling, so thermal and acoustic impact is minimal.

What must the system already provide for this quad-channel kit to function?

A DDR5 server or workstation platform with four 288-pin RDIMM slots that support ECC registered memory.
