2 TB DDR5 4800 ECC RDIMM kit

This 2 TB kit contains sixteen 128 GB DDR5 4800 CL40 registered DIMMs built for Dell PowerEdge R860 rack servers. It targets IT teams running virtualisation, in-memory databases or heavy container workloads that need maximum registered ECC capacity per socket.

DDR5 4800 registered bandwidth ceiling

The modules run at DDR5 4800 (PC5 38400) with CL40 latency and 1.10 V. Registered buffering adds one cycle of address/control delay, so peak throughput is limited by the JEDEC 4800 MT/s data rate rather than lower CAS figures available on unbuffered parts.

Tool-free DIMM installation, population rules apply

Each 288-pin RDIMM seats in the standard server slot without tools, but the R860 requires specific slot population order for 4Rx4 modules to initialise correctly. Mis-populated channels are the most common cause of POST failure; consult the server service manual for the exact sequence.

Questions about this item

How do I choose between the 16-module 2TB kit and smaller capacity options?

This kit provides 2TB total capacity using 16 modules of 128GB each, designed for Dell PowerEdge R860 servers that support 4Rx4 DDR5 RDIMM configurations.

What does the DDR5 4800 CL40 rating mean for actual server performance?

The modules run at 4800 MT/s with CAS latency 40 at 1.1V, delivering PC5-38400 bandwidth for registered ECC workloads on compatible platforms.

How does the 288-pin DDR5 RDIMM interface affect compatibility and speed limits?

The 288-pin registered DDR5 form factor with ECC and 4Rx4 organization is keyed for DDR5-only server motherboards and operates at the rated 4800 speed when the platform supports it.
