256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains four 64 GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It operates at 1.1 V and uses a 288-pin form factor. The modules are validated for ThinkMate GPX-XH20-28S4-8HGX GPU-optimised servers.

Suited for ThinkMate server upgrades

IT teams expanding memory in the specified ThinkMate platform will find the correct speed, rank and voltage pre-matched. Systems that require unbuffered UDIMMs, a different pin count or non-ECC memory cannot use this registered kit.

2Rx4 dual-rank organisation

Each 64 GB module is built as 2Rx4, doubling the banks per DIMM compared to single-rank parts. This rank structure determines maximum capacity per channel on the target platform and must match the server memory population rules.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the memory slots on the Thinkmate GPX-XH20-28S4-8HGX server?

Yes, each 64 GB module uses the standard 288-pin DDR5 RDIMM layout required by that platform.

What is the correct order for populating the four 64 GB modules during installation?

Follow the server manual’s channel sequence; the kit is a matched 4×64 GB set so all slots should be filled identically.

Will the ECC registered modules need firmware updates or battery replacements over their service life?

No, DDR5 ECC RDIMMs operate without onboard firmware or batteries; they remain functional until physical replacement.
