  • 2 V operation reduces power draw per module
  • Validated for Dell PowerEdge 13th Gen rack servers

64GB DDR4 ECC RDIMM Kit

This A-Tech 64GB kit contains four 16GB DDR4-2133 registered ECC modules built for Dell PowerEdge 13th generation rack servers. It targets administrators upgrading R430, R530, R630, R730, R730xd, R830 or R930 platforms that require 2Rx4 registered memory.

Replacing lower-capacity RDIMMs

The kit replaces smaller DDR4 RDIMM sets when workloads exceed the current memory ceiling. The jump is worth it when virtualisation density, database caching or in-memory analytics push the existing configuration into paging or ballooning.

64GB total capacity headroom

Four dual-rank 16GB modules at CL15 1.2V deliver 64GB of registered ECC capacity across four channels. The configuration handles typical multi-tenant VM clusters and mid-size databases; it runs out when workloads demand more than 64GB per socket or require load-reduced DIMMs for higher densities.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the DIMM slots on a Dell PowerEdge R730?

Yes, the 288-pin DDR4 RDIMM form factor matches the registered DIMM slots used across the Dell PowerEdge 13th Gen rack server line, including the R730.

What is the correct installation sequence for the four 16 GB modules in a Dell PowerEdge R630?

Populate the DIMM slots following the server's channel guidelines — typically one module per channel per CPU first — and ensure each registered DIMM clicks fully into the 288-pin socket.

Can I later add non-ECC unbuffered DIMMs to expand this 64 GB kit in a PowerEdge R830?

No, ECC registered modules cannot be mixed with non-ECC unbuffered memory; all installed DIMMs must share the same ECC type.
