128GB DDR4 3200 ECC RDIMM kit

This 128GB kit contains two 64GB DDR4 3200 registered DIMMs built for THINKMATE GPX-QT8-24E2-8GPU servers. Each module runs at 1.2V with CL22 latency and 4Rx4 organisation. ECC and registered buffering protect data integrity in multi-GPU workloads.

DDR4 3200 registered DIMM limits

The DDR4 3200 standard caps transfer rates at 3200 MT/s per pin, and registered modules add one clock cycle of address buffering. Four-rank 4Rx4 density increases electrical load on the memory controller, so maximum populated speeds may drop below the rated 3200 MT/s depending on the platform.

Upgrade from lower-capacity DDR4 RDIMMs

Replacing smaller DDR4 RDIMMs with this 128GB kit doubles or quadruples capacity per channel while keeping the same voltage and form factor. The jump is worth it when GPU-accelerated workloads exhaust memory bandwidth or capacity on the existing configuration.

Questions about this item

Should I pick the 2 x 64 GB kit or look for a different capacity for my ThinkMate server?

The kit provides 128 GB total across two 64 GB modules, matching the DDR4 3200 CL22 4Rx4 1.2 V ECC RDIMM specification for the GPX-QT8-24E2-8GPU platform.

What does the 3200 MT/s rating mean once the memory is installed in the server?

The modules run at DDR4 3200 (PC4-25600) with a CAS latency of 22 cycles, delivering registered ECC bandwidth at 1.20 V for the ThinkMate GPU-optimised server.

How does the 288-pin DDR4 RDIMM interface limit performance in this system?

The registered 288-pin DDR4 RDIMM interface operates at 3200 MT/s with CL22 timing and 4Rx4 organisation, capping throughput to the PC4-25600 standard for the compatible ThinkMate server.
