Capacity and role

This 64 GB DDR4 RDIMM provides registered ECC memory for servers and workstations that require data integrity at scale. The dual-rank 2Rx8 organisation suits multi-socket platforms needing high density per slot.

Thermals and power

Operating at 1.20 V, the module runs within standard DDR4 voltage limits for registered DIMMs. Registered buffering reduces electrical load on the memory controller, helping maintain stable thermals in densely populated chassis.

Sustained load behaviour

ECC circuitry corrects single-bit errors continuously during prolonged workloads, preventing silent data corruption. CL22 latency at 3200 MT/s delivers consistent throughput for memory-bound tasks such as virtualisation and database caching.

Perguntas sobre este artigo

How do I install the 288-PIN DDR4 RDIMM module and which notch alignment step is often missed?

Align the single off-centre notch on the 288-PIN DDR4 RDIMM with the slot key, press vertically until both retention clips click, and verify the module sits flush; the step most often missed is confirming both clips have fully engaged.

What maintenance or replacement will the 64GB DDR4 3200 ECC Registered module need over its service life?

No scheduled maintenance is required; replacement is only necessary if a memory test reports uncorrectable ECC errors or the module physically fails.

What thermal or electrical limit appears first when the 1.20V CL22 2Rx8 module runs under sustained load?

The 1.20V operating voltage and CL22 timing define the electrical envelope; sustained load first hits the thermal throttling threshold of the DDR4 3200 specification before any voltage limit.
