Server memory upgrade

This OWC 128GB DDR5 4800 CL40 4Rx4 288-pin 1.1V ECC Registered RDIMM is built for Dell PowerEdge C6600 C6620 MX760C R660 R6615 servers. It delivers 128GB of registered ECC capacity in a single module for workloads that require error correction and high density. The module is not compatible with standard desktop computers or unbuffered memory configurations.

Registered ECC requirement

The single specification that decides fit is the registered ECC DDR5 4800 interface with 4Rx4 organisation at 1.1V. Only systems that accept registered ECC RDIMMs at this speed and rank layout can use the module; mixing with unbuffered or load-reduced DIMMs is not supported.

No bundled accessories

The upgrade ships as a standalone memory module without cables software or heat spreaders. Installation is a direct DIMM swap so the only change is the added capacity and ECC protection for the supported Dell PowerEdge platforms.

Questions about this item

How does the 4800 MT/s speed translate to bandwidth inside a Dell PowerEdge R660?

The module runs at DDR5-4800 with a CL40 latency, delivering PC5-38400 peak transfer rates when the server's memory controller is configured for that speed.

What does the 288-pin ECC Registered RDIMM form factor require from the system board?

It needs a 288-pin DDR5 RDIMM slot that supports registered ECC modules; it will not work in unbuffered or load-reduced slots.

What physical clearance does the 128 GB 4Rx4 module need in a Dell PowerEdge MX760C chassis?

The module is a standard-height 288-pin RDIMM without a heat spreader, so it fits in the regular DIMM sockets of the listed PowerEdge servers.
