64GB DDR5-4800 EC8 RDIMM kit for Dell PowerEdge

This 64GB kit contains two 32GB DDR5-4800 EC8 registered DIMMs built for 16th generation Dell PowerEdge rack and tower servers including the T560, R660, R760, R860 and R960 families. It delivers ECC error correction and registered buffering required by these platforms. The modules operate at 1.1V with CL40 latency.

DDR5-4800 speed ceiling and mixed-module behaviour

The memory runs at the DDR5-4800 (PC5-38400) data rate; if faster or slower modules are also installed, the system will clock all channels to the slowest module present. Registered ECC DIMMs of this type are not compatible with desktop or laptop platforms that only accept non-ECC unbuffered memory. No heat spreader is fitted, so airflow across the modules must be provided by the server chassis.

Two-module installation and common seating errors

The kit ships as a matched pair of 288-pin DIMMs; installation follows the server manual's channel and population rules, which typically require specific slot sequences per CPU. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong order for the processor count, and failing to update the system BIOS before adding capacity.

Questions about this item

Should I choose the 2x32GB kit or look for a single 64GB module?

The kit ships as two 32GB modules, giving 64GB total and letting you populate two channels for maximum bandwidth on Dell PowerEdge 16th Gen servers.

What does DDR5-4800 CL40 mean for real-world throughput in my R760?

The modules run at 4800MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth when the memory controller operates at the rated DDR5-4800 speed.

Is EC8 RDIMM the same as standard registered ECC, and will it work in my T560?

EC8 RDIMM denotes ECC registered DDR5 with on-die ECC; it is the required form factor for the listed Dell PowerEdge 16th Gen rack and tower models.
