128GB DDR5 RDIMM kit for workstations

This kit provides 128GB of registered ECC memory across eight 16GB modules. It is built for compatible Intel Xeon W-3400X workstation platforms that require registered DIMMs with error correction. The modules operate at DDR5 6000 with a CL30 latency profile. Buyers needing unbuffered UDIMMs or non-ECC memory should look elsewhere.

Registered ECC with 288-pin DDR5 interface

Each module is a 288-pin DDR5 RDIMM rated at 6000 MT/s (PC5 48000) with timings of 30-39-39-96 at 1.40V. The registered buffer and on-die ECC plus side-band ECC are the single specification that determines compatibility; the motherboard must support registered ECC DDR5 and the W790 chipset with eight-channel architecture. Systems without registered memory support cannot use this kit.

Fits Intel W790 octo-channel workstations

The eight-module population fills all channels on a W790 motherboard designed for Xeon W-3400X processors. Intel XMP 3.0 profiles simplify configuration when the platform allows overclocked memory operation. Dedicated on-module temperature sensors assist thermal monitoring. Builders using consumer chipsets, fewer than eight channels, or unbuffered memory slots cannot install this product.

Questions about this item

What does the DDR5 6000 speed rating mean when the kit is installed in a workstation?

The kit runs at 6000 MT/s with CL30-39-39-96 timings at 1.40 V when the XMP 3.0 profile is enabled on a compatible Intel W790 motherboard.

How does the registered DDR5 interface with ECC affect data integrity and throughput?

The RDIMM modules include on-die ECC and side-band ECC, providing error correction for each 16 GB module while the register buffers address and command signals for stable octo-channel operation.

What physical slot and motherboard layout are required for the 8-module kit?

The kit uses 288-pin DDR5 RDIMM modules and requires an Intel W790 chipset motherboard with eight memory slots to populate all 8 x 16 GB modules.
