512GB DDR4-3200 ECC RDIMM kit

This NEMIX RAM kit provides 512GB across eight 64GB registered DDR4 modules rated at 3200MHz with CL22 timing. It operates at 1.20V and uses 288-pin 4Rx4 ECC RDIMM form factor designed for compatible THINKMATE GPU-optimised servers.

Suited for THINKMATE GPX-QT8-24E2-8GPU deployments

Builders expanding a qualified THINKMATE platform can use this matched kit. Systems requiring unbuffered UDIMMs, lower-density modules, non-ECC memory or a different registered DIMM specification should select an alternative part.

4Rx4 registered ECC architecture

The 4Rx4 organisation and registered buffer are the decisive compatibility factors; the motherboard and CPU memory controller must explicitly support 4Rx4 registered ECC RDIMMs at DDR4-3200 for the kit to function.

Questions about this item

Will these 288-pin DDR4 RDIMMs fit the memory slots on a Thinkmate GPX-QT8-24E2-8GPU server?

Yes, the kit is built for that exact model and uses the standard 288-pin DDR4 RDIMM form factor required by its motherboard.

What is the correct way to seat all eight 64 GB modules so the server recognises the full 512 GB?

Populate every channel in the order shown in the server manual, press each module straight down until both retention clips click, then verify the total in BIOS before loading the OS.

How do I know when a 4Rx4 registered ECC module from this kit should be replaced?

The server logs correctable ECC errors; when the count rises sharply or uncorrectable errors appear, swap the offending stick — each module carries a lifetime replacement guarantee.
