Dell PowerEdge server memory kit

This 32GB kit contains four 8GB DDR4 registered ECC DIMMs built for Dell PowerEdge R730, R730xd and T630 servers. Each module runs at 2133MHz with CL15 timing at 1.2V. The 1Rx4 organisation and registered buffer suit multi-socket server boards that require error-correcting memory.

288-pin DIMM installation notes

Align the notch on each 288-pin stick with the slot key and press firmly until the retention clips click. The system provides 12 sockets per CPU and 24 sockets in a dual-CPU configuration. Mixing registered ECC with unbuffered ECC modules is not supported, and x4 and x8 DRAM variants must not share the same memory bank.

Sustained load behaviour

Registered buffering and ECC correction maintain data integrity during continuous server workloads. The 1.2V operating voltage keeps power draw predictable across all populated sockets. Maximum supported capacity reaches 384GB with registered DIMMs or 768GB with load-reduced DIMMs when 32GB modules are available.

Questions about this item

How do I verify the CM1024722133ECCREG1R4 kit is running at 2133 MHz with CL15 timings after installation?

Enter the server BIOS or use a tool like CPU-Z to confirm the memory speed reads 2133 MHz and the timings show 15-15-15 at 1.2 V.

What does the 32 GB kit contain and are any extra parts required for the Dell PowerEdge R730?

The box includes four 8 GB registered ECC DIMMs; no additional components are needed for the R730, R730xd or T630.

Should I choose the 1Rx4 registered version or a different rank for my PowerEdge T630 upgrade?

This kit uses 1Rx4 registered modules, which are fully compatible; do not mix with unbuffered ECC or different-rank DIMMs in the same bank.
