128GB DDR5 ECC RDIMM Kit

This 128GB kit contains four 32GB DDR5 4800 registered DIMMs built for Dell Precision 7960 rack and tower workstations. It targets IT teams and power users who need error-correcting server memory to keep critical workloads stable.

Registered 2Rx4 Design at 1.1V

Each module uses a 288-pin RDIMM form factor with a 2Rx4 organisation and runs at 1.1V without a heat spreader. The registered buffer reduces electrical load on the memory controller, allowing all four slots to be populated reliably in compatible Precision 7960 chassis.

Upgrade From Smaller or Non-ECC Kits

The kit replaces lower-capacity DDR5 kits or non-ECC memory that cannot meet server-class data integrity requirements. The jump is worth it when workloads demand the full 128GB capacity with registered ECC protection on supported Precision 7960 platforms.

Questions about this item

What DDR5 speed does the PC5-38400 rating deliver in practice?

The kit runs at 4800 MT/s, which is the standard JEDEC speed for PC5-38400 DDR5 memory.

Will the 288-pin registered DIMMs fit a Dell Precision 7960 workstation?

Yes, the 288-pin RDIMM form factor matches the Dell Precision 7960 rack and tower workstation memory slots.

Do I need to populate all four slots in matched pairs for the 2Rx4 modules to initialise?

Install the four 32 GB modules in the channel order shown in the Dell Precision 7960 manual; mixing populations can prevent the registered ECC DIMMs from training correctly.
