A-Tech 16GB (2x8GB) DDR4 2133 ECC RDIMM 1Rx4 memory upgrade

Dell PowerEdge 13th Gen RDIMM kit

This 16 GB DDR4 kit contains two 8 GB registered ECC modules built for Dell PowerEdge R430, R530, R630, R630 XL, R730, R730 XL, R730xd, R730xd XL, R830 and R930 rack servers. It targets administrators who need to expand memory capacity on these 13th generation platforms. The modules are not compatible with desktop or laptop systems that require non‑ECC unbuffered memory.

Two matched modules simplify installation

The kit ships as a matched pair so both DIMMs carry identical 1Rx4 organisation, CL15 latency and 1.20 V operation. Using two identical modules lets the server populate a channel pair without mixing ranks or speeds, which avoids the automatic down‑clocking that occurs when dissimilar modules are installed together.

Registered ECC design suits dense server configs

Each 288‑pin RDIMM uses a register to reduce electrical load on the memory bus, allowing the platform to support larger total capacities than unbuffered alternatives. The lack of a heat spreader keeps the module height low, which helps in tightly packed rack chassis, while ECC circuitry corrects single‑bit errors to protect data integrity in continuous workloads. Buyers who need load‑reduced ECC or non‑ECC memory cannot use this kit.
