Dell 1V1N1 server upgrade

This 16GB DDR5 module replaces the Dell 1V1N1 part in compatible servers and workstations. It delivers registered ECC memory for data integrity in multi-tasking and virtualised workloads. The single-rank design keeps signal loading low on populated channels.

Sustained throughput stability

Registered buffering and on-die ECC maintain consistent latency during extended compute jobs. The 1.10V operating voltage reduces thermal pressure inside dense chassis under continuous load. CL40 timing at 4800MHz supports steady bandwidth without frequency throttling.

1Rx8 registered ECC constraint

The module is a 288-pin RDIMM with 1Rx8 organisation and EC8 error-correction. Systems requiring unbuffered DIMMs, different rank counts or non-ECC memory cannot use this part. Verify the platform memory specification before ordering.

Questions about this item

How much heat and power does the 1.10V DDR5 4800 RDIMM produce under continuous server loads?

At 1.10V standard DDR5 voltage the 16GB module draws minimal power and generates low heat, helping keep chassis temperatures stable during all-day operation.

What motherboard slot and memory controller features are required to run this 288-pin ECC RDIMM?

A DDR5-capable server board with a 288-pin RDIMM slot and an integrated memory controller that supports ECC registered operation at 4800 MT/s is required.

Can the CL40 1Rx8 module share a channel with older DDR5 RDIMMs of different rank or latency?

Mixing 1Rx8 CL40 modules with other ranks or latencies is not recommended; the memory controller will downclock to the slowest common timing and may disable ECC features.
