384GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 384GB of DDR5 memory across four 96GB registered DIMMs. It is built for IT professionals and system integrators who manage Thinkmate GPX-XH20-28S4-8HGX GPU-optimised servers and need validated, error-correcting capacity for heavy workloads.

Registered ECC with CL40 latency

Each module operates at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and runs at 1.1V. The 2Rx8 registered ECC design is the single specification that determines compatibility; only systems that accept 288-pin DDR5 RDIMMs with this exact speed, voltage and rank structure can use the kit.

Four-module kit with lifetime replacement

The package contains four matched 96GB DIMMs pre-configured as a 384GB set, eliminating the need to source individual sticks. NEMIX RAM stress-tests every module under load and backs the kit with a lifetime replacement guarantee, so the bundle delivers verified stability and long-term support without extra procurement steps.

Questions about this item

How does the 4800 MT/s speed translate once the four 96 GB modules are installed in the ThinkMate server?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput across all four registered DIMMs when the platform supports that data rate.

What does the 288-pin RDIMM form factor and registered ECC design mean for compatibility?

These are 288-pin DDR5 RDIMMs with on-board register and ECC; they require a server motherboard that accepts registered ECC DDR5 modules and will not work in unbuffered or non-ECC slots.

What physical clearance and power do the 96 GB modules need?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, operating at 1.1 V, so they fit regular DIMM sockets and draw standard DDR5 voltage.
