Server Memory Upgrade

This OWC module is a 128GB DDR5 4800 ECC Registered RDIMM designed for Dell PowerEdge HS5610 and HS5620 servers. It operates at 1.1V with CL40 latency and a 4Rx4 rank configuration. The 288-pin form factor matches the DDR5 slots in these specific systems.

Workstation and Server Builders

The module suits administrators upgrading compatible Dell PowerEdge servers or building new configurations that require registered ECC memory. It will not work in standard desktop computers, unbuffered memory slots, or systems requiring load-reduced DIMMs. Buyers needing unbuffered memory or non-ECC modules should look elsewhere.

Registered ECC Requirement

This is a registered ECC DIMM that cannot be mixed with unbuffered or load-reduced memory in the same system. The server platform must support registered ECC DDR5 modules for this upgrade to function. Verify the motherboard documentation for registered ECC compatibility before purchase.

Questions about this item

Should I choose the 128GB module or add multiple smaller sticks to reach the same capacity?

This single 128GB DDR5 4800 CL40 4Rx4 registered ECC RDIMM fills one slot, leaving others free for future expansion.

What does the 4800MHz speed mean for my Dell PowerEdge HS5610 or HS5620 server?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput the platform supports for registered ECC memory.

Is the 288-pin DDR5 interface compatible with standard desktop motherboards?

No, this 288-pin DDR5 registered ECC RDIMM at 1.1V is designed for Dell PowerEdge HS5610 and HS5620 servers and will not work in consumer desktops.
