64GB DDR5 ECC RDIMM kit for Thinkmate

This registered DDR5 memory kit delivers 64 gigabytes across four 16-gigabyte modules built for the Thinkmate GPX-XH8-22S4-8GPU GPU-optimized server. Error-correcting code and registered buffering protect data integrity in mission-critical workloads. The kit targets IT professionals who need validated stability in multi-GPU server deployments.

DDR5 4800 CL40 1.10V 288-pin registered

The decisive specification is DDR5 4800 MT/s at CL40 latency with 1.10 volt operation on 288-pin registered DIMMs. Each module uses a 1Rx8 organisation and major OEM chips from Samsung Micron or Hynix. Systems that require a different speed voltage or rank structure will not accept this kit.

Four-module kit enables quad-channel population

The package contains four matched 16-gigabyte RDIMMs allowing full quad-channel population on compatible Thinkmate motherboards. No heat spreaders are included so clearance inside dense GPU chassis remains unchanged. Installers simply seat the modules following the server manual for immediate capacity expansion.

Questions about this item

What does the 4800 MHz speed deliver when installed in the Thinkmate server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, giving the rated bandwidth once the platform enables the XMP or JEDEC profile.

How does the registered ECC design affect the memory controller?

Registered buffering reduces electrical load on the controller while ECC corrects single-bit errors, a requirement for the supported Thinkmate platform.

Will the 288-pin RDIMMs fit the server's DIMM slots without a heat spreader?

Yes, the bare 288-pin DDR5 RDIMM form factor matches the Thinkmate GPX-XH8-22S4-8GPU slots and the kit includes four 16 GB modules.
