Dell Server DDR4 Upgrade

This 16GB kit contains two 8GB DDR4 2133 registered ECC modules built for Dell systems. The 2Rx4 organisation and PC4 17000 rating target servers and workstations that require registered memory with error correction. It suits IT teams expanding capacity in qualified Dell platforms.

Verify Registered ECC Support

Confirm the target Dell model accepts 288-pin DDR4 registered DIMMs at 2133 MT/s with ECC enabled. Registered modules will not function in platforms limited to unbuffered memory. Check the system manual or vendor memory configurator for exact slot population rules and maximum capacity per channel before ordering.

288-Pin Registered Build

The 288-pin DDR4 form factor locks into standard server DIMM sockets with the registration buffer between the DRAM and the memory controller. This arrangement reduces electrical load on the bus, allowing larger configurations in multi-socket Dell servers. The modules are tested for compatibility across the supplier's 200000 supported configurations.

Questions about this item

Does the kit include only the two 8 GB modules or any extra brackets or cables?

The kit contains the two 8 GB DDR4 2133 registered DIMMs and nothing else; no brackets, cables or additional parts are supplied.

When should I pick the 2Rx4 16 GB kit instead of a 32 GB or 64 GB option?

Choose this 16 GB kit when your Dell system needs two 8 GB registered modules; larger capacities such as 32 GB or 64 GB require different module densities or more slots.

What does the PC4 17000 label mean for actual throughput in a compatible Dell server?

PC4 17000 indicates a peak transfer rate of 17 000 MB/s at 2133 MT/s, which the modules deliver when installed in a supported Dell platform.
