256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains sixteen 16 GB DDR5 registered DIMMs rated at 4800 MT/s with CL40 latency and 1.10 V operation. It is built for Dell PowerEdge R760 rack servers that require ECC registered memory.

Suited for administrators expanding R760 capacity

IT teams running virtualisation clusters, in-memory databases or large container fleets on Dell PowerEdge R760 hardware will match the platform's validated configuration. Buyers needing non-ECC modules, unbuffered DIMMs or speeds beyond 4800 MT/s should look elsewhere.

Handles 256 GB across sixteen slots

The kit populates all sixteen channels with 1Rx8 organisation, delivering the full 256 GB the platform supports at the rated 4800 MT/s. Workloads exceeding this capacity or requiring higher data rates will require a different server platform.

Questions about this item

Does the Dell PowerEdge R760 need a specific BIOS revision before these 256GB DDR5 4800 CL40 kits will post?

The modules are built to the DDR5 4800 PC5-38400 JEDEC standard, so the R760 will recognise them at 4800 MT/s without a special BIOS update; install the 16 pieces and the server trains at the rated speed.

Can I keep any existing DDR5 RDIMMs in the R760 while adding this 16-module kit?

All slots must run at the same voltage and timing; the kit operates at 1.10 V CL40 1Rx8, so any other DDR5 RDIMMs left in the chassis must match those exact figures or the system will fall back to the lowest common settings.

How can I confirm the full 256 GB is active after installation?

Boot the R760, enter the BIOS or iDRAC inventory screen and verify that all 16 slots show 16 GB each at 4800 MT/s with ECC enabled; the total should read 256 GB.
