Capacity and fit

This 768 GB kit contains twelve 64 GB DDR4 3200 registered ECC RDIMMs built for the THINKMATE GPX-QT8-24E2-8GPU server. Each module runs at 1.2 V with CL22 latency and a 4Rx4 organisation. The 288-pin form factor matches the platform’s memory slots exactly.

Thermals and power

Operating at the standard 1.2 V DDR4 voltage keeps power draw low across all twelve modules. No heat spreaders are fitted, so airflow through the server chassis handles cooling without added bulk. Registered buffering reduces electrical load on the memory controller during sustained workloads.

What the kit changes

Populating every slot with matched 64 GB RDIMMs lets the GPX-QT8-24E2-8GPU reach its maximum supported memory capacity for GPU-accelerated tasks. ECC protection corrects single-bit errors in flight, and the registered design stabilises signal integrity across the full 12-module population.

Questions about this item

How do I install the 12 288-pin DDR4 RDIMM modules in the ThinkMate server and which step is commonly missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both locking tabs click, then verify all 12 modules are detected in the BIOS memory configuration screen.

What maintenance or replacement will the 768GB ECC registered memory kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; only a failed stick would need replacement under the lifetime warranty.

What limit appears first when the 4Rx4 CL22 1.20V modules run sustained workloads on the GPU-optimised server?

The CAS latency of CL22 at 3200 MT/s sets the timing ceiling, and the 1.20V operating voltage caps thermal headroom before any other spec becomes the bottleneck.
