Server Memory Kit

This 256 GB kit contains two 128 GB DDR4 3200 ECC registered DIMMs built for ThinkMate GPU-optimised servers. The modules deliver PC4-25600 bandwidth with CL22 latency at 1.2 V for stable operation in mission-critical workloads.

Build Integration

Each 288-pin RDIMM uses a 4Rx4 organisation that requires a registered-memory-capable motherboard and registered-channel population rules. The registered buffers reduce electrical load on the memory controller, freeing signal integrity headroom for large-capacity configurations.

Capacity Headroom

The dual-module kit provides 256 GB of error-correcting capacity suited to virtualisation hosts, GPU compute nodes and large-scale database buffers. Workloads exceeding this total or requiring higher frequencies will need additional DIMM slots or faster memory speeds.

Questions about this item

What CAS latency will the CL22 timing impose under sustained server workloads?

The modules run at CL22, which is the primary latency figure for every sustained memory access cycle.

How much heat does a 1.20 V 4Rx4 RDIMM generate when running 24/7?

Each 128 GB module operates at 1.20 V without a heat spreader, so thermal output depends on chassis airflow rather than an on-module cooler.

Which server platform must already be installed for this 288-pin DDR4 kit to function?

The kit is validated for THINKMATE GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU GPU-optimised servers.
