A-Tech 64GB DDR5 4800MHz ECC RDIMM 2Rx4 EC8 Server RAM

SKU CH-683V-8PFGM

64GB DDR5 4800MHz ECC registered DIMM with 2Rx4 organisation for HP/HPE server upgrades

  • Capacity64GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS Latency40
  • Voltage1.10V
  • ECCYes
  • 64GB capacity expands server memory for heavy workloads
  • DDR5 4800MHz speed delivers PC5-38400 bandwidth for data-intensive tasks
  • ECC RDIMM with 2Rx4 rank corrects errors to protect critical data
  • Registered 288-pin design buffers signals for stable multi-module operation
  • 10V standard voltage reduces power draw per module

64GB DDR5 ECC RDIMM Server Module

This 64GB DDR5 registered DIMM provides error-correcting memory for server and workstation platforms. It operates at 4800MHz with a CAS latency of 40 and a standard voltage of 1.10V. The module uses a 2Rx4 rank configuration with major-brand DRAM ICs.

DDR5 4800MHz Registered Interface Limits

The DDR5 4800 standard sets the maximum transfer rate at PC5-38400 for this registered form factor. Registered buffering adds a clock cycle, which stabilises heavy loads but prevents use in unbuffered desktop boards. ECC functionality requires a platform that supports registered ECC memory.

64GB Single-Module Capacity Constraint

This single 64GB module fills one 288-pin slot and cannot be split across channels. Systems needing more than 64GB per channel must populate additional slots with matching modules. Buyers who need smaller increments or non-ECC memory should select a different specification.

Questions sur cet article

Should I choose the 64GB DDR5-4800 ECC RDIMM or a lower-capacity module for my HP/HPE server?

The 64GB 2Rx4 module suits servers needing maximum capacity per slot; smaller DIMMs leave room for future expansion but reduce density.

What does the 4800MHz rating deliver inside a compatible server?

It provides PC5-38400 bandwidth at 1.10V with CL40 latency, running at DDR5-4800 speed when the platform supports that data rate.

How does the 288-pin DDR5 RDIMM interface limit performance in practice?

The registered 288-pin DDR5 slot caps operation to the module's 4800MT/s rating and requires a platform that supports ECC RDIMM memory.
