Server Memory Kit for Dell PowerEdge R960

This 128GB kit contains eight 16GB DDR5 registered DIMMs built for the Dell PowerEdge R960 rack server. Each module operates at 4800 MT/s with a CAS latency of CL40 and a voltage of 1.10V. The ECC registered design targets data integrity in enterprise workloads.

DDR5 RDIMM Interface Limits

The 288-pin DDR5 RDIMM standard used here runs at a fixed 4800 MT/s data rate with CL40 timing and 1.10V supply. Registered buffering adds one clock cycle of latency while reducing electrical load on the memory controller. Systems must support DDR5 ECC registered modules at this exact speed and voltage to function.

1Rx8 Rank Determines Fit

Each 16GB module uses a single-rank 1Rx8 organisation, which decides whether the server's memory controller can populate all eight slots at the rated speed. Buyers needing dual-rank density or higher capacities per slot cannot use this kit.

Questions about this item

Should I choose the 8x16GB kit or a different capacity for my Dell PowerEdge R960?

The 128GB kit provides eight 16GB registered DIMMs, filling eight slots with 1Rx8 modules at DDR5 4800 CL40.

What does the DDR5 4800 CL40 rating deliver in a live server?

The modules run at 4800 MT/s with a CAS latency of 40 cycles at 1.10V, giving registered ECC bandwidth for the R960 platform.

How does the PC5-38400 designation relate to the 288-pin RDIMM interface?

PC5-38400 is the JEDEC peak data-rate label for DDR5 4800 on the 288-pin registered DIMM form factor.
