NEMIX RAM 256GB (4x64GB) DDR5 4800 CL40 2Rx4 ECC RDIMM Dell XR8610t/XR8620t memory upgrade

Dell PowerEdge XR8610t and XR8620t memory kit

This 256GB kit contains four 64GB DDR5 4800 registered ECC RDIMMs built for Dell PowerEdge XR8610t and XR8620t rack servers. The modules run at 1.1V with CL40 latency and a 2Rx4 organisation. They are designed for IT teams who need maximum capacity in these specific Dell platforms.

Replacing lower-capacity DDR5 RDIMMs

Upgrading from smaller registered modules is worthwhile when workloads demand more memory channels filled at the native 4800 MT/s speed. The jump makes sense for virtualisation hosts, database nodes or high-density compute clusters that hit capacity limits before they hit bandwidth limits. Systems already running at the full 256GB population cannot add more memory without changing platform.

DDR5 4800 registered ECC limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and requires registered DIMMs with on-die ECC for this server class. Voltage is fixed at 1.1V and the 288-pin RDIMM form factor prevents use in unbuffered or UDIMM slots. Maximum capacity per module is 64GB at this speed, so further density increases need a newer memory generation.
