512GB DDR4 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR4 3200 registered ECC memory across eight 64GB modules. It is built for ThinkMate GPU-optimised servers that require 288-pin RDIMMs with 4Rx4 organisation and CL22 latency.

Suited for ThinkMate GPX-PS4 server upgrades

The kit targets administrators expanding memory in compatible ThinkMate GPX-PS4-12A1-2GPU or 4GPU systems. It is not for desktop PCs, laptops or workstations that accept only unbuffered UDIMMs, nor for platforms limited to lower capacities or different pin counts.

Straightforward DIMM installation

Modules slot into the server's 288-pin DDR4 RDIMM sockets without tools. Populate all eight slots identically to maintain channel balance. The usual issue is mixing registered and unbuffered DIMMs or skipping the BIOS memory training step after installation.

Questions about this item

Does this kit require a THINKMATE GPX-PS4-12A1-2GPU or GPX-PS4-12A1-4GPU server to function?

Yes, the modules are validated for those specific GPU-optimised THINKMATE servers and are sold as a system-specific upgrade for them.

Can the 4Rx4 registered ECC RDIMMs operate alongside older 2Rx4 DDR4 modules in the same server?

Mixing different rank architectures on the same channel is not recommended; the server's memory controller expects uniform rank configuration per channel for stable operation.

How can I confirm the full 512 GB is recognised and ECC is active after installation?

Enter the server BIOS or UEFI at boot, open the memory information screen and verify that all eight 64 GB modules show as registered ECC at 3200 MT/s with CL22 timings.
