System-specific DDR4 kit

NEMIX RAM supplies a 384GB kit built as twelve 32GB DDR4 3200 modules for ThinkMate GPX-XS12-24S3-8GPU servers. The registered ECC RDIMMs run at 1.20V with CL22 timing and use a 2Rx8 organisation. IT teams upgrading GPU-optimised ThinkMate platforms receive a matched set validated for that chassis.

Registered ECC at DDR4 3200

The single specification that determines fit is the registered ECC RDIMM interface running at DDR4 3200 (PC4-25600). Only systems expecting 288-pin registered ECC modules at this speed and voltage will accept the kit; unbuffered or non-ECC boards will not post. Buyers who need unbuffered DIMMs or a different data rate must select another part.

Thermals and power in normal use

Each module operates at 1.20V without a heat spreader, relying on server chassis airflow for cooling. The registered buffer adds a small power overhead compared with unbuffered DIMMs, but total draw stays within standard DDR4 limits for 32GB densities. Acoustic impact is negligible because the modules have no moving parts.

Questions about this item

Will the DDR4 3200 speed run at its rated frequency once installed in the ThinkMate server?

The modules are rated for DDR4 3200 (PC4-25600) and will operate at that speed provided the server's memory controller and BIOS support the 3200 MT/s data rate.

What does the registered ECC RDIMM design mean for the memory bus?

Registered DIMMs place a register between the DRAM and the memory controller, reducing electrical load so the server can populate all slots with ECC error correction active.

How many DIMM slots does the 12-module kit fill in the GPX-XS12-24S3-8GPU chassis?

The kit contains twelve 288-pin RDIMMs, each 32 GB, so it occupies twelve DDR4 memory slots in the server.
