Capacity and Compatibility

This kit provides 384GB of DDR4 memory across six 64GB registered DIMMs built for Thinkmate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU servers. It targets administrators who need maximum ECC capacity in those specific GPU-optimised platforms.

Installation Notes

Modules install in standard 288-pin DDR4 slots and operate at 1.2V without additional configuration. The 4Rx4 organisation demands that the server memory controller supports quad-rank registered DIMMs; systems limited to dual-rank modules will not recognise the full capacity.

Deciding Specification

The 4Rx4 rank architecture is the single attribute that determines whether this kit works in your chassis. Verify that your Thinkmate server documentation explicitly lists support for quad-rank registered DDR4 before purchase.

Questions about this item

How can I confirm the 384GB kit is running at 3200 MT/s with CL22 after installation?

Check the memory speed and CAS latency in the server BIOS or a hardware monitoring tool; they should show DDR4 3200 and CL22 for each of the six 64GB modules.

What exactly ships in the box and do I need any extra parts to install the 6x64GB RDIMM kit?

The package contains the six 288-pin DDR4 ECC RDIMM modules only; no heat spreaders, cables or tools are included, and nothing else is required for installation.

Why choose the 4Rx4 384GB configuration over other capacities for my ThinkMate GPU server?

The 4Rx4 organisation delivers the maximum 384GB capacity across six slots at 1.2 V, matching the ThinkMate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU qualified memory specification.
