System-Specific 128 GB DDR4 3200 ECC RDIMM

This NEMIX RAM module delivers 128 GB of DDR4 3200 registered ECC memory in a single 288-pin RDIMM. It operates at 1.2 V with a CAS latency of CL22 and uses a 4Rx4 rank organisation built from major OEM DRAM chips. The part is validated for Thinkmate VSX-R5-760S1 and VSX-R5-540RTP workstations.

For servers needing maximum density per slot.

IT teams running Thinkmate VSX-R5-760S1 or VSX-R5-540RTP platforms can fill a single DIMM slot with 128 GB of ECC registered memory, simplifying high-capacity configurations. Workstations or desktops that require unbuffered non-ECC UDIMMs or lower-density modules cannot use this registered 4Rx4 RDIMM.

Registered 4Rx4 ECC RDIMM form factor decides fit

The module is a 288-pin DDR4 RDIMM with registered signalling and on-die ECC, requiring a motherboard chipset and BIOS that support registered 4Rx4 population rules. If the target system only accepts unbuffered UDIMMs or limits rank count per channel, this DIMM will not function.

Questions about this item

Will the 288-pin DDR4 RDIMM fit my ThinkMate VSX-R5-760S1 workstation?

The module is a 288-pin DDR4 RDIMM built to the PC4-25600 standard and listed as compatible with the ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations.

What is the correct way to seat this registered ECC module so the system recognises the full 128 GB?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that 128 GB appears at 3200 MT/s with ECC active.

Does the 4Rx4 organisation require any special firmware or matching modules for long-term reliability?

The 4Rx4 registered ECC design works with the ThinkMate platform without extra firmware; ECC corrects single-bit errors on the fly, and the module is stress-tested for continuous server workloads.
