NEMIX RAM 1TB (16x64GB) DDR5 4800 ECC RDIMM THINKMATE GPX-XH20-28S4-8HGX memory upgrade

1TB DDR5 ECC RDIMM kit for Thinkmate GPX-XH20

This 1 TB kit contains sixteen 64 GB DDR5 4800 registered DIMMs built for the Thinkmate GPX-XH20-28S4-8HGX GPU-optimised server. ECC and registered buffering protect data integrity in multi-socket, memory-heavy workloads. It is not suited for desktop boards that require unbuffered non-ECC modules.

DDR5 4800 registered ECC limits capacity

The DDR5 4800 standard tops out at PC5-38400 bandwidth with CL40 latency at 1.1 V, so total throughput is fixed by the memory controller and cannot exceed this kit's rated speed. Registered signalling adds one cycle of command delay, and ECC consumes extra bits per transfer, so raw bandwidth is lower than unbuffered equivalents at the same clock.

Sixteen 2Rx4 modules fill every slot on the target

The kit delivers exactly 1 TB across sixteen dual-rank 2Rx4 modules, matching the full population the Thinkmate GPX-XH20-28S4-8HGX supports. Builders needing a different total capacity or a mixed-rank configuration must choose another kit, because this part number only ships as a complete sixteen-module set.
