Rank 1Rx8

  • Massive 128GB capacity handles heavy server workloads
  • DDR5 4800 speed feeds data fast to CPUs
  • ECC registered design protects data integrity
  • 10V operation reduces power draw per module
  • Eight 16GB sticks populate 288-pin slots efficiently

Server Memory Kit for Dell PowerEdge R660xs

This 128GB kit contains eight 16GB DDR5 modules built for registered ECC server platforms. It targets administrators upgrading Dell PowerEdge R660xs rack servers with validated memory.

DDR5 4800 Registered ECC RDIMM

The decisive specification is the registered ECC DDR5 4800 interface with CL40 latency at 1.1V. Only systems that accept 288-pin DDR5 RDIMMs with on-die ECC can use this kit.

128GB Capacity Across Eight Slots

Eight 16GB single-rank modules fill eight DIMM slots and suit memory-intensive virtualization or database workloads. Servers needing more than 128GB or configurations requiring dual-rank density cannot use this kit.

Questions about this item

What does the 4800 MT/s speed mean for actual throughput in a server?

The DDR5 4800 rating sets the maximum data rate at 4800 MT/s per module; real-world bandwidth depends on the memory controller, channel population and workload mix.

How does the PC5-38400 designation relate to the module's interface?

PC5-38400 is the JEDEC label for DDR5 4800 and confirms a 288-pin RDIMM form factor with registered signalling and on-die ECC.

What physical space and power are needed to install this 8-module kit?

Eight 288-pin DDR5 RDIMM slots running at 1.1 V are required; the modules have no heat spreaders, so standard DIMM clearance applies.
