Capacity and configuration

This kit delivers 384 GB of DDR5 memory across four 96 GB modules, built as 2Rx8 registered ECC RDIMMs for the ThinkMate GPX-XS8-24S4-4GPU workstation. The PC5-38400 rating confirms a 4800 MT/s data rate at 1.10 V with CL40 latency. No heat spreader is fitted, so airflow must be managed by the chassis.

Suited workloads and limits

The 2Rx8 organisation and ECC protection make this memory appropriate for multi-socket server tasks, large dataset processing and virtualisation clusters that require registered modules. Systems that only accept unbuffered UDIMMs, platforms limited to lower capacities per slot, or builds needing a heat spreader for restricted airflow cannot use this kit.

Deciding specification

The registered ECC RDIMM form factor with 2Rx8 rank structure is the single attribute that determines compatibility; the motherboard must explicitly support registered DDR5 ECC modules at this density and rank configuration.

Questions about this item

Should I choose the 384GB kit with four 96GB modules or a different capacity for my THINKMATE workstation?

This kit provides 384GB total across four 96GB DDR5 4800 RDIMMs. Select it when your workload needs that full capacity and the motherboard has four available slots for registered ECC modules.

What does the DDR5 4800 speed rating mean once the memory is installed in the THINKMATE GPX-XS8-24S4-4GPU?

The modules run at 4800 MT/s with CL40 latency at 1.10V. The registered ECC design adds a clock cycle for command buffering, so real-world throughput matches the PC5-38400 spec while providing error correction for server workloads.

How does the 288-pin DDR5 RDIMM interface limit what I can do with this kit?

The 288-pin RDIMM form factor fits only DDR5 server and workstation boards that support registered ECC memory. It cannot be used in consumer desktop boards, laptops, or systems requiring unbuffered UDIMMs.
