64GB DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs built for Dell PowerEdge R660xs rack servers. Each module runs at 1.1V with CL40 latency and includes on-die ECC for data integrity. The 288-pin RDIMM form factor fits server motherboards that require registered memory.

Registered design and ECC

Registered buffering reduces electrical load on the memory controller so the platform can populate all slots at rated speed. ECC detects and corrects single-bit errors to protect workloads that cannot tolerate silent data corruption. The kit is validated for the specified Dell server model.

64GB capacity for virtualization and databases

Four ranks of 16GB modules give 64GB total, a practical size for moderate virtualization clusters, in-memory databases or high-thread-count application servers. Workloads that exceed this footprint will need additional DIMM slots or higher-density modules. The 4800 MT/s rate provides baseline DDR5 bandwidth for these tasks.

Questions about this item

Will the 16 GB DDR5 RDIMM modules need replacement after a certain service interval?

The modules have no moving parts and no specified wear-out cycle; they remain in service until a capacity upgrade or a motherboard change requires different memory.

What limits sustained throughput when the kit runs at 4800 MT/s continuously?

The CL40 latency and the single-rank 1Rx8 organisation set the timing ceiling that appears first under prolonged load.

How much heat and power does the 1.1 V kit produce during all-day operation?

At 1.1 V the four registered DIMMs draw modest power and run without heat spreaders, so chassis airflow handles the thermal load.
