Dell PowerEdge DDR5 RDIMM Kit

This 64GB kit contains two 32GB DDR5 4800 CL40 ECC Registered RDIMM modules built for specific Dell PowerEdge servers. It targets IT teams maintaining or expanding C6600, C6620, MX760C, R660 and R6615 platforms. It is not for desktop PCs or workstations that require unbuffered memory.

Registered ECC with 2Rx8 Organisation

The modules run at 1.1V with a 288-pin interface and a 2Rx8 rank structure, delivering PC5-38400 bandwidth. Registered buffering and on-die ECC protect data integrity in multi-socket server workloads. Mixing these with unbuffered or load-reduced DIMMs is not supported.

JEDEC-Compliant Dual-Module Pack

Two matched sticks enable dual-channel population without manual pairing. JEDEC and RoHS compliance ensures warranty-safe installation in the listed Dell systems. No heat spreaders are fitted, so airflow follows the server's original thermal design.

Questions about this item

What does the 4800 MT/s speed mean once the modules are installed in a Dell PowerEdge R660?

The DDR5-4800 rating sets the maximum data rate the modules will run at when the server memory controller operates at its rated speed.

How does the PC5-38400 standard limit performance in these systems?

PC5-38400 defines the peak transfer rate for DDR5-4800; the server cannot exceed this bandwidth with these DIMMs.

What physical slot and clearance do the 288-pin RDIMMs need in a PowerEdge C6600?

They require a standard 288-pin DDR5 RDIMM socket and fit the server's low-profile DIMM slots without a heat spreader.
