1 TB DDR5-4800 ECC RDIMM kit

This 1 TB kit consists of eight 128 GB DDR5-4800 registered ECC modules rated at PC5-38400 with CL40 latency and 1.1 V operation. It is built for Thinkmate GPX-XH20-28S4-8HGX GPU-optimised servers that require 288-pin 4Rx4 registered DIMMs.

Suited for Thinkmate server upgrades

The kit fits administrators expanding memory in the specified Thinkmate platform or replacing failed modules with validated registered ECC RDIMMs. It is not for systems that accept only unbuffered UDIMMs, for boards limited to lower densities than 128 GB per slot, or for workloads that demand speeds above DDR5-4800.

4Rx4 registered DDR5 organisation

Each module uses a 4Rx4 organisation, so the memory controller must support quad-rank registered DDR5 DIMMs at the native 4800 MT/s data rate. Verify that the target server qualified this rank configuration before purchase.

Questions about this item

Does the kit include all eight 128 GB modules or do I need to buy any separately?

The package contains the full 1 TB kit with eight 128 GB modules, so nothing else is required for the capacity listed.

Should I choose the 4Rx4 CL40 version or look for a different rank and latency?

This kit is built as 4Rx4 with CL40 at 4800 MT/s; select it when your server requires that exact rank and latency combination.

What does the PC5-38400 rating mean once the memory is installed in a ThinkMate server?

It indicates DDR5 4800 operation at 1.1 V with ECC and registered buffering, delivering the rated throughput for compatible ThinkMate GPU-optimised systems.
