System-specific 512GB DDR4 kit

This 512GB kit contains eight 64GB DDR4 3200 ECC registered DIMMs built for the Thinkmate GPX-XS12-24S3-8GPU server. It targets IT teams expanding memory capacity in GPU-optimised platforms that require registered error-correcting modules.

288-pin registered modules without spreaders

Each DIMM uses a 288-pin DDR4 RDIMM form factor with 4Rx4 organisation and operates at 1.20V. The lack of heat spreaders means airflow in the server chassis must handle thermal dissipation during sustained workloads.

DDR4 3200 bandwidth ceiling

The PC4-25600 interface caps peak throughput at the DDR4 3200 rate, so total system bandwidth cannot exceed this standard. CL22 latency and quad-rank density also limit how many modules the memory controller can address at full speed.

Questions about this item

What DDR4 speed does this 512GB kit run at and what bandwidth does PC4-25600 cap it to?

The modules run at DDR4 3200 and the PC4-25600 rating caps practical bandwidth at 25600 MB/s.

What physical slot and module dimensions does the 288-pin RDIMM require?

Each 64GB module uses a standard 288-pin DDR4 RDIMM form factor and needs a matching server DIMM slot.

How are the eight 4Rx4 modules installed and which population step is often missed?

Populate all eight slots in the order the server manual specifies; the step most often missed is following the exact channel sequence for 4Rx4 ranks.
