A-Tech 128GB (2x64GB) DDR4 2400 ECC LRDIMM 4Rx4 Server RAM

SKU CH-ZMEA-V0815

A 128 GB dual-channel kit of DDR4 2400 ECC load-reduced DIMMs with 4Rx4 organisation and CL17 latency for servers and workstations

  • Capacity128GB (2 x 64GB)
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredLoad Reduced

Capacity 128GB (2 x 64GB)

  • High capacity 128GB kit handles heavy server workloads

  • DDR4 2400MHz speed delivers fast data throughput
  • Dual-channel 2×64GB layout maximises memory bandwidth
  • Standard 1.20V voltage keeps power draw efficient

Server Memory Kit

This A-Tech kit supplies 128 GB of DDR4 ECC Load Reduced DIMM memory in a matched pair of 64 GB modules. It is built for servers and workstations that require registered LRDIMM modules and will not fit or function in desktop or laptop systems.

4Rx4 Quad Rank Configuration

Each module uses a 4Rx4 organisation, presenting four logical ranks per DIMM to the memory controller. This rank density allows the kit to reach 128 GB in only two slots, but the platform must explicitly support 4Rx4 LRDIMM population rules for the memory to initialise correctly.

128 GB Capacity Headroom

The 128 GB total handles large virtualisation clusters, in-memory databases and heavy multi-tenant workloads with ample headroom. Workloads that scale beyond this capacity or that require higher memory bandwidth than DDR4 2400 provides will need a platform with more slots or a faster memory standard.

Questions about this item

What does the DDR4 2400 speed mean once the modules are installed in a server?

The kit runs at 2400 MT/s with CL17 timing, so the memory controller can sustain the standard DDR4-2400 data rate across both channels when the platform supports it.

How does the LRDIMM interface affect what the system can actually use?

Load Reduced DIMMs buffer the command and address signals, letting the memory controller drive four quad-rank modules per channel without exceeding its electrical load limits.

What physical slot and clearance do these 288-pin modules need?

Each 64 GB stick is a standard 288-pin DDR4 DIMM; it fits any server DIMM socket wired for LRDIMM operation and requires no extra height clearance beyond the usual module profile.
