1 TB DDR5-4800 ECC RDIMM kit

This eight-module kit delivers 1 TB of DDR5 registered memory rated at 4800 MT/s with CL40 latency and 1.10 V operation. It targets Dell PowerEdge R760xa rack servers running virtualization, database or HPC workloads that demand maximum capacity per socket.

Pre-installation checklist

Verify the R760xa BIOS is current and that the memory configuration follows Dell population rules for 4Rx4 registered DIMMs. Confirm the system accepts 288-pin DDR5 RDIMMs and that all eight slots intended for this kit are free and keyed identically.

Sustained-load behaviour

Modules are stress-tested under load using major OEM Samsung, Micron or Hynix DRAM to maintain stability during extended compute runs. Registered signalling and on-die ECC preserve data integrity without throttling when the full 1 TB is active for long periods.

Questions about this item

What comes in the 1 TB kit and is anything else required?

The kit contains eight 128 GB DDR5 4800 ECC registered RDIMM modules, part number MR38400-744K8. No additional memory parts are needed to reach the full 1 TB capacity.

How do I decide between the available capacities or speeds for the R760xa?

This specific kit is offered as a single 1 TB (8 × 128 GB) configuration at DDR5 4800 CL40. Choose it when the server requires the maximum supported density at the standard 4800 MT/s speed.

What does the 4800 MT/s rating mean once the modules are installed in the R760xa?

The modules will run at up to 4800 MT/s with CL40 latency at 1.1 V, delivering the rated PC5-38400 bandwidth per module when the platform operates at its native DDR5 4800 speed.
