ThinkMate GPX-XS8 Workstation Memory

This 512GB DDR5 kit contains sixteen 32GB registered ECC RDIMMs built for the ThinkMate GPX-XS8-24S4-4GPU workstation. It targets IT professionals and system integrators who need maximum validated capacity for memory-intensive server workloads. The modules run at 4800MT/s with CL40 latency and 1.10V operation. Each stick uses a 2Rx8 organisation and 288-pin DDR5 form factor.

Sustained Load Behaviour

Registered buffering and on-die ECC protect data integrity during continuous multi-threaded compute, virtualization or database tasks. The 1.10V DDR5 voltage helps limit thermal output when all sixteen slots stay populated under long-duration workloads. Major OEM Samsung, Micron or Hynix DRAM chips are stress-tested under load to verify stability before shipment. No heat spreaders are fitted, so chassis airflow must handle the thermal density of a full 16-DIMM configuration.

Pre-Installation Checklist

Verify the workstation is the exact ThinkMate GPX-XS8-24S4-4GPU model and that its BIOS revision supports 512GB of DDR5 4800 registered ECC memory. Confirm all sixteen DIMM slots are free and that the motherboard memory topology matches the 16x32GB population rule. Ensure the platform accepts 2Rx8 registered modules at 1.10V without requiring voltage offsets. Cross-reference the part number MR38400-328K16 against the system qualified-vendor list before ordering.

Questions about this item

Does the 1.10 V DDR5 4800 CL40 2Rx8 registered kit run cool enough for 24/7 server loads?

Each 32 GB module operates at 1.10 V with no heat spreader; registered buffering and ECC add minimal overhead so thermals stay within normal DDR5 limits for continuous duty.

Must the ThinkMate GPX-XS8-24S4-4GPU motherboard have all 16 DDR5 RDIMM slots free to use this 512 GB kit?

The kit contains sixteen 288-pin DDR5 RDIMMs; the workstation must provide sixteen compatible registered DIMM slots populated identically for full 512 GB capacity.

Will the CL40 2Rx8 registered modules run alongside older DDR5 DIMMs still installed?

Mixing ranks or latencies is not supported; all sixteen slots should use identical 2Rx8 CL40 registered modules for stable operation.
