Eight green DDR5 RDIMM modules, bare chips, 288 pins, 64 GB each

A-Tech

A-Tech 512GB (8x64GB) DDR5 4800 ECC RDIMM 2Rx4 Server RAM

SKU CH-EGA8-DSGJH

Eight 64 GB DDR5 4800 registered ECC modules deliver 512 GB at 1.1 V with CL40 latency for servers and workstations

  • Capacity512GB (8 x 64GB)
  • Type288-Pin DDR5 SDRAM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCYes

Capacity 512GB (8 x 64GB)

  • 512GB total capacity with eight 64GB modules for maximum server density
  • DDR5 4800MHz speed delivers high bandwidth for demanding workloads
  • ECC registered design detects and corrects data errors automatically
  • Dual rank x4 organisation increases memory throughput per channel
  • 10V standard DDR5 voltage reduces power draw per module

512GB DDR5 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 modules built as registered ECC DIMMs for servers and workstations. It targets administrators who need maximum registered capacity on platforms that support dual-rank x4 modules. The kit is not for desktop or laptop systems, which cannot use registered memory.

Registered DDR5 288-pin form factor

Each module uses the 288-pin DDR5 DIMM form factor and requires a server or workstation motherboard with registered DIMM slots and ECC support. Registered buffering reduces electrical load on the memory controller, freeing the platform to populate all eight slots at the rated 4800 MT/s speed. Buyers must verify their system's qualified vendor list before installation.

Eight dual-rank modules at 1.1V

The eight 2Rx4 modules deliver 512GB total capacity at the standard DDR5 1.1V operating voltage with CL40 latency. This density handles large virtualisation clusters, in-memory databases and heavy compute workloads. Systems limited to fewer DIMM slots, lower maximum capacity per slot, or non-ECC operation cannot use this kit.

Questions about this item

Will the CAS 40 latency at 4800 MHz become the bottleneck during sustained server workloads?

The modules run at DDR5 4800 with CL40 timing; sustained throughput is limited by that latency and the 1.10 V operating voltage.

What thermal and acoustic impact should I expect from eight registered DIMMs operating continuously?

Each 64 GB stick is a 2Rx4 registered module without a heat spreader, drawing 1.10 V at 4800 MHz; total system heat and fan noise depend on your chassis airflow.

Which server platforms can accept this 512 GB kit of 288-pin ECC RDIMMs?

The kit requires a DDR5 server or workstation motherboard with 288-pin RDIMM slots that support 64 GB 2Rx4 EC4 modules at 1.1 V.
