1TB DDR5-4800 ECC kit for Dell PowerEdge

This 1TB kit contains eight 128GB DDR5-4800 registered ECC RDIMMs built for Dell PowerEdge HS5610 and HS5620 servers. Each module runs at 1.1V with CL40 latency and a 4Rx4 organisation. The 288-pin registered design adds a buffer that stabilises heavy memory loads in multi-socket systems.

Suited for HS5610 and HS5620 memory expansion

IT teams upgrading compatible Dell PowerEdge servers to 1TB of DDR5 ECC capacity will use this kit. It is not for standard desktop PCs or workstations that accept only unbuffered non-ECC memory, and it cannot be mixed with load-reduced DIMMs in the same chassis.

Registered ECC RDIMM form factor decides fit

The 288-pin registered ECC RDIMM form factor is the single specification that determines whether this kit fits your system. Only platforms designed for DDR5 registered ECC modules with matching voltage and rank configuration will accept it.

Questions about this item

Should I buy the 8-module 1 TB kit or add single 128 GB modules?

The kit supplies eight matched 128 GB modules for a total of 1 TB; using the full kit ensures identical rank, timing and voltage across all slots.

What does the DDR5 4800 CL40 rating deliver in a Dell PowerEdge HS5610 or HS5620?

The modules run at 4800 MT/s with a CAS latency of 40 cycles, giving the server the rated JEDEC standard bandwidth for DDR5-4800.

How does the 288-pin RDIMM interface and registered ECC design affect compatibility?

The 288-pin registered ECC RDIMM format is required by the PowerEdge HS5610 and HS5620 and cannot be mixed with unbuffered or load-reduced memory.
