Dell PowerEdge Compatibility

This 64GB kit contains four 16GB DDR4 registered DIMMs validated for Dell PowerEdge R730, R730xd and T630 servers. The modules run at 2133MHz with CL15 timing at 1.2V and use a 2Rx4 organisation. ECC and register buffering provide the error correction and signal integrity required by these platforms.

Server Upgrade Scenarios

The kit suits administrators expanding memory in the listed PowerEdge models up to the 384GB registered ECC limit or the 768GB load-reduced ceiling. It is not for workstations or desktops that accept only unbuffered non-ECC memory, nor for systems that cannot mix 2Rx4 modules within the same bank.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation, while ECC corrects single-bit errors that accumulate over long runtimes. The 1.2V DDR4 voltage keeps power draw predictable across fully populated configurations of 12 sockets per CPU or 24 sockets in dual-CPU deployments.

Questions about this item

Will this 288-pin DDR4 kit work in my Dell PowerEdge R730xd without any other memory changes?

The kit is validated for the R730xd and installs directly into the 288-pin DDR4 slots; the server must already support registered ECC memory and you should not mix registered and unbuffered ECC modules in the same bank.

Can I keep my existing 8 GB unbuffered ECC DIMMs and add these 16 GB registered modules?

Mixing registered and unbuffered ECC memory is not supported in the PowerEdge R730, R730xd or T630, so the older unbuffered sticks must be removed before installing this registered kit.

How do I confirm the system sees all 64 GB at 2133 MHz with ECC active after installation?

Enter the BIOS or iDRAC interface and verify the memory configuration shows 64 GB total, 2133 MT/s speed, registered ECC mode enabled and no memory errors reported.
