System-Specific Memory Kit

This NEMIX RAM kit delivers 256GB across two 128GB DDR5 RDIMMs validated for the THINKMATE VSX-R5-760RTP7 workstation. Registered ECC operation protects data integrity in mission-critical server and workstation workloads.

Registered ECC with 4Rx4 Organisation

Each module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V using 4Rx4 Samsung, Micron or Hynix die. The registered buffer and on-die ECC reduce electrical load on the memory controller while correcting single-bit errors.

288-Pin RDIMM Form Factor for Compatible Slots

The 288-pin DDR5 RDIMMs install directly into the workstation's registered DIMM slots without a heat spreader, leaving clearance for dense CPU-cooler arrangements. Buyers needing unbuffered UDIMMs or non-ECC memory for consumer platforms cannot use this kit.

Questions about this item

What does the 4800 MT/s speed mean once the modules are installed in the Thinkmate VSX-R5-760RTP7?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated transfer rate and timing when the workstation's memory controller operates at its native DDR5 4800 setting.

How does the ECC RDIMM interface affect what the memory controller can do?

The registered ECC design adds a clock cycle of buffering and single-bit error correction, so the controller sees a stable electrical load per DIMM and can maintain data integrity across all 256 GB.

What physical slot and clearance do the 288-pin modules need?

Each 128 GB module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits any DDR5 RDIMM slot that accepts full-height registered DIMMs.
