8GB DDR4 2666MHz ECC RDIMM for servers

This registered DIMM adds 8GB of error-correcting memory to compatible server platforms. It runs at DDR4 2666 speed with CL19 latency and 1.2V operation. The module targets administrators who need validated capacity for Supermicro qualified systems. Single-rank organisation keeps electrical loading low on populated channels.

Registered DDR4 limits signal loading on dense

The RDIMM buffer reduces electrical load on the memory controller, allowing more modules per channel than unbuffered alternatives. DDR4 2666 sets the maximum transfer rate at PC4-21300 bandwidth. ECC circuitry detects and corrects single-bit errors but cannot fix multi-bit failures. Systems must support registered ECC DIMMs or the module will not function.

288-pin RDIMM installs in keyed server slots only

Align the notch with the socket key and press until the retention clips engage. Mixing registered and unbuffered DIMMs prevents boot. Populating slots in the wrong sequence can disable channels. Verify the motherboard qualified-vendor list before installation because unsupported configurations cause memory training failures.

Questions about this item

Should I pick the 8GB 2666MHz CL19 registered ECC module or look for a different capacity?

This module is an 8GB single-rank 1Rx8 DDR4 2666MHz CL19 registered ECC DIMM. Choose it when your server needs exactly 8GB per slot at 2666MHz with ECC and registered buffering.

What does the 2666MHz rating deliver once the stick is installed in a server?

The module runs at DDR4 2666MHz with CL19 latency at 1.2V, providing 2666 MT/s data transfer in a compatible registered DIMM slot.

How does the 288-pin RDIMM interface limit performance in practice?

The 288-pin registered DIMM interface supports DDR4 2666MHz operation at 1.2V with ECC, and the registered buffer allows higher-capacity configurations than unbuffered modules.
