Eight-module DDR4 kit

This 512GB kit contains eight 64GB DDR4 ECC RDIMM modules running at 2133 MHz with CL15 latency and 1.20V operation. Registered design and 3DS/TSV stacking enable high-density server configurations. The 288-pin form factor fits DDR4 server and workstation platforms.

Who this suits

Suits administrators expanding memory in DDR4 servers that support 64GB ECC RDIMM modules with 2S4Rx4 octal-rank topology. Not for desktop or laptop users, nor for systems limited to lower-density or unbuffered DIMMs.

Deciding specification

The 2S4Rx4 (8Rx4 3DS/TSV) octal-rank registered ECC configuration determines compatibility; the motherboard must explicitly support this rank structure and 64GB module density.

Questions about this item

Will the 288-pin DDR4 DIMM slots in my server accept these 64 GB registered modules?

Yes, each module is a 288-pin DDR4 RDIMM designed for server and workstation platforms that support registered ECC memory.

What is the correct seating order for the eight modules across the memory channels?

Consult the system manual for the exact channel population sequence; the kit contains eight identical 64 GB modules that must be installed in the prescribed slots for optimal performance.

Do the 64 GB modules require any firmware updates or battery-backed maintenance over time?

No firmware updates or battery maintenance are needed; the modules operate at 1.2 V with on-board ECC and are covered by a lifetime warranty.
