Rank 4Rx4

  • Massive 1 TB capacity from eight 128 GB modules
  • ECC registered design detects and corrects data errors
  • 2666 MHz DDR4 speed with CL19 latency
  • Low 1.2 V voltage reduces server power draw
  • Backward compatible with 2133 MHz and 2400 MHz systems

Server Memory Kit 1TB DDR4 2666MHz

This OWC kit provides 1TB of DDR4 memory across eight 128GB registered ECC RDIMMs. The modules run at 2666MHz with CL19 latency at 1.2V and use a 288-pin form factor. They are designed for server and workstation platforms that require registered memory with error correction.

Suited for Registered ECC Platforms Only

These modules fit servers, workstations and NAS systems that support DDR4 2666, 2400 or 2133MHz registered ECC memory. They will not work in standard desktop computers that accept only unbuffered non-ECC DIMMs. Builders needing consumer desktop memory should look elsewhere.

Registered ECC 4Rx4 Architecture Decides

Each 128GB module uses a 4Rx4 rank configuration with registered ECC buffering. The motherboard memory controller must support this specific registered ECC topology. Systems limited to unbuffered or lower-rank DIMMs cannot use this kit.

商品問答

Will the 288-pin DDR4 RDIMM modules fit my server's memory slots?

These 288-pin DDR4 RDIMMs require server or workstation motherboards with registered DIMM slots; they will not fit standard desktop UDIMM sockets.

What is the correct installation sequence for the eight 128GB modules?

Populate all eight slots following the motherboard's channel map — typically alternating channels per CPU — and ensure each module clicks fully into the 288-pin socket.

When should I expect to replace the 4Rx4 ECC registered modules?

Replace modules only if ECC logs report uncorrectable errors or the system fails memory diagnostics; otherwise DDR4 RDIMMs typically run for the server's service life.
