System-Specific DDR4 Kit

This 48GB kit contains three 16GB DDR4 2133MHz registered ECC DIMMs built for Dell PowerEdge R730, R730xd and T630 servers. Each module runs at 1.2V with CL15 timing and a 2Rx4 organisation. The 288-pin load-reduced design targets enterprise workloads that require error correction and signal buffering.

Verify Server Configuration

Confirm the server uses a CPU that supports registered ECC memory and check how many of the 12 DIMM slots per processor are already populated. The platform accepts either registered or unbuffered ECC but forbids mixing the two types in the same system. Matching rank and DRAM organisation within each memory bank is also required for stable operation.

Three-Module Kit Contents

The package delivers three identical 16GB sticks, letting you populate a single channel or split them across channels depending on the CPU count. No heat spreaders, cables or software utilities are included. The manufacturer backs the modules with a limited lifetime warranty when purchased directly from Computer Memory Solutions.

Questions about this item

Does the kit include anything besides the three 16 GB DDR4 modules?

The package contains only the three 288-pin DDR4 2133 MHz ECC Registered DIMMs; no heat spreaders, cables or tools are supplied.

Should I pick the 48 GB kit or add smaller modules to reach the server limit?

Each CPU provides 12 DIMM slots, so the 3 x 16 GB kit occupies three slots per processor and leaves room to expand toward the 384 GB registered ECC maximum.

What does the PC4-17000 rating mean once the memory is installed in a PowerEdge R730?

It confirms the modules run at 2133 MHz with CL15 timing at 1.2 V, delivering the standard bandwidth and latency the server's memory controller expects for registered ECC operation.
