Capacity and purpose

This kit provides 256GB of DDR4 ECC registered memory across 16 modules of 16GB each. It is built for ThinkMate GPX-QN6-42E2-8NVLINK GPU-optimised servers that require registered DIMMs with error correction.

Sustained-load behaviour

Each module runs at 3200MHz with CL22 latency and 1.2V operation using a 2Rx8 organisation. Registered buffering and ECC maintain data integrity during continuous server workloads without generating excess heat because no spreader is fitted.

Pre-order checks

Confirm your server accepts 288-pin DDR4 RDIMMs and supports the full 256GB capacity across all 16 slots. Verify the motherboard qualification list for this exact part number MR25600-628K16 before installation.

Questions about this item

How much heat does the 1.2V DDR4 kit add when running continuously?

At 1.2V the 16 modules draw minimal power and run without heat spreaders, so thermal contribution inside a server chassis is low.

Which server platform must already be present for these 288-pin RDIMMs to work?

The kit is validated for ThinkMate GPX-QN6-42E2-8NVLink GPU-optimised servers and requires that platform's DDR4 RDIMM slots.

Can the CL22 2Rx8 modules share channels with older DDR4 RDIMMs already installed?

Mixing ranks and latencies is not recommended; populate all 16 slots with this matched kit for stable registered ECC operation.
