256 GB DDR4 3200 ECC RDIMM kit

This 256 GB kit contains four 64 GB DDR4 3200 MHz registered DIMMs with ECC and a CAS latency of CL22. The modules run at 1.20 V and use a 4Rx4 organisation on 288-pin connectors. They are validated for ThinkMate GPX-QT8-24E2-8GPU GPU-optimised servers.

Suited for ThinkMate server upgrades

This memory fits administrators expanding a ThinkMate GPX-QT8-24E2-8GPU server that requires registered ECC RDIMMs at 3200 MHz. It is not for systems that accept only unbuffered UDIMMs, for platforms limited to lower densities per slot, or for any non-ThinkMate hardware without verified DDR4 RDIMM support.

4Rx4 registered ECC at 3200 MHz

The decisive specification is the 4Rx4 registered ECC configuration at DDR4 3200 MHz with CL22 timing. The motherboard and memory controller must support 4Rx4 registered modules at this speed and voltage for the kit to function correctly.

Questions about this item

How much heat and power do the four 64 GB DDR4 3200 ECC RDIMMs add when the server runs continuously?

Each module operates at 1.20 V; the registered design and ECC logic keep power draw low and heat output modest for 24/7 server workloads.

What must the ThinkMate GPX-QT8-24E2-8GPU already have to accept this 256 GB kit?

The server needs free 288-pin DDR4 RDIMM slots that support 4Rx4 registered ECC modules at 3200 MHz.

Will these CL22 4Rx4 modules work alongside older DDR4 RDIMMs already installed in the same ThinkMate server?

Mixing ranks and latencies can prevent the system from training at 3200 MHz; populate all channels with identical 4Rx4 CL22 modules for stable operation.
