A-Tech 512GB (8x64GB) DDR4 3200 ECC LRDIMM 4Rx4 Server RAM

SKU CH-D9SH-H0HA0

Eight 64 GB DDR4 3200 ECC LRDIMM modules deliver 512 GB of load-reduced quad-rank server memory at 1.2 V

  • Capacity512GB (8 x 64GB)
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V
  • ECCYes

Capacity 512GB (8 x 64GB)

  • 512 GB total capacity from eight 64 GB modules for large-scale server workloads
  • DDR4 3200 speed with CL22 latency accelerates data throughput in compatible systems
  • ECC Load Reduced DIMM design corrects errors and reduces electrical load on the memory bus
  • Quad-rank 4Rx4 organisation maximises density within each 288-pin module
  • 2 V standard DDR4 voltage ensures efficient power use in qualified platforms

Server Memory Kit for DDR4 Platforms

This A-Tech kit delivers 512GB of DDR4 3200 ECC LRDIMM capacity across eight 64GB modules. It is built for servers and workstations that require load-reduced registered memory to support large memory footprints. Desktop and laptop systems cannot use these modules.

Quad-Rank 4Rx4 Configuration

Each 64GB module uses a 4Rx4 organisation, presenting four logical ranks per DIMM to the memory controller. This rank density allows the kit to reach 512GB in eight slots, but the platform must explicitly support 4Rx4 LRDIMMs at DDR4 3200 speeds. Systems limited to lower rank counts or standard RDIMMs will not recognise the full capacity.

Eight-Module Matched Kit

The eight modules are tested together and shipped as a single kit to ensure consistent timing at CL22 and 1.20V operation. Installing the full set populates eight 288-pin DIMM slots and enables the platform to run the complete 512GB configuration without mixing disparate modules.

Questions about this item

What real-world throughput does the DDR4 3200 speed deliver for the 512 GB kit?

The kit runs at DDR4 3200 (PC4-25600) with CL22 latency, giving each 64 GB module a 3200 MT/s data rate that scales across all eight modules in supported server channels.

How does the ECC Load Reduced DIMM interface affect usable capacity and speed?

The LRDIMM buffer reduces electrical load on the memory bus, allowing the 4Rx4 quad-rank 64 GB modules to operate at the full 3200 MT/s rate while maintaining ECC error correction.

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

Each module uses a standard 288-pin DDR4 DIMM slot and operates at 1.2 V; the kit requires eight available LRDIMM-compatible slots in a server or workstation motherboard.
