384GB DDR4-3200 ECC RDIMM kit for Thinkmate GPU

This six-module kit delivers 384GB of DDR4 3200 registered ECC memory built for Thinkmate GPX-XT6-24S3-8NVLINK GPU-optimised servers. Each 64GB module operates at 1.2V with CL22 latency and a 4Rx4 organisation using major OEM DRAM. The registered design adds signal buffering required by high-density server platforms.

Fills all six slots in compatible Thinkmate servers

The 288-pin RDIMM form factor installs directly into the server’s DDR4 memory slots without adapters or risers. Registered buffering reduces electrical load on the memory controller, allowing the full 384GB population at rated speed. No heat spreaders are fitted, so airflow from the server’s existing cooling path passes over the DRAM unimpeded.

Runs at standard 1.2V DDR4 voltage

Registered modules draw slightly more power than unbuffered DIMMs but remain within the DDR4 1.2V specification. The server’s stock fan curves typically keep module temperatures in normal operating range without audible fan ramp. ECC correction handles single-bit errors transparently during sustained compute or GPU workloads.

Questions about this item

Does the 4Rx4 organisation and CL22 latency become the bottleneck when the kit runs at 3200 MT/s all day?

The 4Rx4 rank layout and CL22 timing set the electrical ceiling at DDR4-3200; sustained throughput will not exceed the rated 25600 MB/s per module.

What is the thermal and acoustic profile of six registered DIMMs drawing 1.2 V continuously in a dense server chassis?

Each 64 GB RDIMM operates at 1.20 V without a heat spreader; total kit power scales with all 384 GB active, so chassis airflow must handle the combined load.

Which motherboard slot population rules must the ThinkMate GPX-XT6-24S3-8NVLINK already satisfy for this 6×64 GB kit to post?

The board must provide six 288-pin DDR4 RDIMM slots wired for registered ECC and support 4Rx4 modules at 3200 MT/s in the required channel order.
