Capacity and Form Factor

This kit provides 1TB of registered DDR5 server memory across eight 128GB modules. Each module uses the 288-pin RDIMM form factor with a 4Rx4 rank configuration and operates at 1.10V. It is built for Dell PowerEdge R760 systems requiring high-density ECC memory.

Suited For And Limits

It suits administrators upgrading a PowerEdge R760 to its maximum supported capacity for virtualisation, database or analytics workloads that demand error correction. It is not for consumer desktops, workstations that require unbuffered DIMMs, or any platform that cannot address 4Rx4 registered modules at this density.

Sustained Load Behaviour

Modules are stress tested under load to verify stability during continuous operation. The registered buffer and on-die ECC maintain data integrity across all ranks during prolonged, multi-threaded workloads. CL40 latency and 4800 MT/s throughput remain consistent without thermal throttling, as the design omits a heat spreader for dense chassis airflow.

Questions about this item

Will this 8 x 128 GB DDR5 kit run in a Dell PowerEdge R760 without extra hardware?

The modules are built to Dell PowerEdge R760 specifications, so they install directly into the server’s DDR5 RDIMM slots with no additional parts required.

Can I mix these 4800 MT/s 4Rx4 RDIMMs with slower DDR5 modules already in the R760?

The server will operate all installed DDR5 at the lowest common speed and rank configuration, so adding these 4800 MT/s 4Rx4 modules alongside slower kits will down-clock the faster memory.

How do I confirm the full 1 TB is recognised and ECC is active after installation?

Check the system BIOS or iDRAC inventory — it should show 1 TB total across eight 128 GB RDIMMs at 4800 MT/s with ECC status reported as enabled.
