1TB DDR5 Registered ECC Kit

This 1TB kit contains eight 128GB DDR5 RDIMMs that operate at 4800 MT/s with CL40 latency. The modules are built for Dell Precision 7960 rack and tower workstations and run at 1.1V.

4Rx4 Registered Architecture

Each module uses a 4Rx4 organisation with registered buffering and on-die ECC, so the memory controller sees a single electrical load per DIMM slot. This topology is required for the workstation chipset to populate all eight slots at the rated 4800 speed.

Sustained Server Workloads

Registered buffering and ECC correction keep data integrity intact during long compute passes such as rendering, simulation or database transactions. The 1.1V operating point limits thermal output when all eight slots are driven continuously at 4800 MT/s.

Questions about this item

What does the 4800 MT/s rating mean for actual throughput in a Dell Precision 7960 workstation?

The modules run at DDR5 4800, which corresponds to PC5-38400 bandwidth, so each module can move data at that rated speed when installed in a compatible system.

How does the 288-pin DDR5 RDIMM interface affect what the memory can do?

The 288-pin RDIMM form factor with registered signalling and ECC allows the memory to be used in server and workstation platforms that require registered DIMMs with error correction.

What physical space and power does the 8 x 128 GB kit need to fit and run?

Each module is a standard 288-pin DDR5 RDIMM operating at 1.10 V, so the kit occupies eight DIMM slots and draws power at that voltage.
