Server-specific memory kit

This 32GB kit contains two 16GB DDR4 registered DIMMs built for the Dell PowerEdge R730. The modules are ECC registered and validated for server workloads that require error correction and signal integrity.

DDR4 2133 registered limits

Registered DDR4 at 2133MHz with CL15 timing runs at 1.2V and uses a 288-pin interface. The R730 supports up to 384GB with RDIMMs or 768GB with LRDIMMs across 24 sockets when two CPUs are installed.

Registered ECC requirement

Only registered ECC DDR4 DIMMs are compatible; unbuffered or non-ECC modules will not function in this platform. Buyers who need unbuffered memory or consumer speeds should select a different product.

Questions about this item

Should I pick the 32 GB 2 x 16 GB kit or a single 16 GB module?

The 32 GB kit gives you 32 GB in two matched 16 GB modules, which is ideal for populating both channels on the Dell PowerEdge R730 and leaves the remaining 22 slots free for future expansion up to 384 GB registered ECC RDIMM.

What does the DDR4 2133 PC4 17000 rating mean for actual throughput in the server?

Each module runs at 2133 MT/s, delivering up to 17 GB/s theoretical bandwidth per stick; the R730 memory controller will operate them at this speed when all slots are populated with registered ECC DIMMs.

Does the 288 pin registered ECC DDR4 interface limit total capacity on the R730?

The R730 supports up to 384 GB with registered ECC RDIMMs across 24 sockets; this 288 pin DDR4 kit fits that standard and can be combined with identical modules to reach the platform maximum.
