Server Memory Upgrade

This A-Tech module provides 64GB of DDR4 2933 registered ECC memory in a single 288-pin DIMM. It is built for servers and workstations that require error-correcting registered modules to maintain data integrity under heavy workloads.

Thermals and Power

Operating at the standard DDR4 voltage of 1.20V, the module runs within normal thermal limits for registered server memory. The registered buffer reduces electrical loading on the memory controller, contributing to stable operation in densely populated slots.

Capacity and Rank Configuration

The 64GB density is delivered in a 2Rx4 organisation, which determines how the memory controller addresses the chips. Systems limited to single-rank or lower-density modules will not support this configuration.

Points forts

  • 64 GB capacity handles large server workloads
  • DDR4 2933 MHz speed moves data fast
  • ECC RDIMM design protects data integrity
  • 2 V operation keeps power draw low
  • 2Rx4 rank layout fits registered DIMM slots

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify the system detects 64GB at 2933MHz in BIOS.

What maintenance or replacement will this ECC RDIMM need later?

No routine maintenance is required; replace only if memory diagnostics report uncorrectable errors or the module fails to post.

What limit appears first under sustained load with this CL21 1.20V module?

The CAS latency of 21 cycles at 2933MHz sets the timing floor, so throughput plateaus before voltage or thermal limits are reached.
