Server memory upgrade kit

This 128GB kit contains four 32GB DDR5 4800 CL40 ECC Registered RDIMMs built for Dell PowerEdge R660XS and R760XS servers. It targets administrators who need to expand memory capacity in these specific platforms.

Straightforward DIMM installation

Modules seat in the standard 288-pin DDR5 slots on the server motherboard. The registered design requires all populated slots to use registered ECC DIMMs; mixing with unbuffered or load-reduced memory will prevent the system from booting.

Registered ECC with 2Rx8 organisation

The 2Rx8 rank configuration and registered buffer are the decisive compatibility factors for the PowerEdge R660XS and R760XS memory controllers. Systems that require unbuffered or load-reduced modules cannot use this kit.

Perguntas sobre este artigo

How do I verify the 4800 CL40 DDR5 ECC Registered modules are running correctly after installing them in my PowerEdge R660XS?

Check the BIOS memory configuration screen or run a server diagnostic; it should report four 32 GB DDR5 4800 CL40 2Rx8 registered ECC DIMMs at 1.1 V.

What exactly ships in the 128 GB kit and do I need anything else for the R760XS?

The kit contains four 32 GB DDR5 4800 PC5-38400 CL40 2Rx8 288-pin 1.1 V ECC Registered RDIMMs; no additional parts are required for the listed PowerEdge models.

Why choose the 4 x 32 GB 4800 CL40 ECC Registered RDIMM kit instead of a different capacity or speed?

This kit delivers 128 GB total across four slots at the JEDEC-standard 4800 MT/s CL40 timing required by the R660XS and R760XS, using 2Rx8 registered ECC modules at 1.1 V.
