256GB DDR4 ECC RDIMM kit

This NEMIX RAM kit supplies 256GB of DDR4 3200 ECC registered memory in two 128GB modules. It runs at 1.20V with CL22 latency and uses a 4Rx4 organisation on 288-pin RDIMMs. The memory is validated for THINKMATE GPX-XS12-24S3-8GPU GPU-optimised servers.

Suited for ThinkMate server upgrades

This kit fits administrators expanding memory in the specified THINKMATE server where ECC registered DIMMs are required. It is not for desktop PCs or laptops that accept only unbuffered non-ECC modules. It is also not for systems limited to lower capacities per slot or to single-rank DIMMs.

Verify slot count and population rules

Confirm the server has enough free 288-pin DDR4 RDIMM slots for two modules and check the motherboard manual for supported ranks per channel. Ensure the BIOS recognises 4Rx4 modules at the target speed and that the operating system can address the full 256GB capacity.

Questions about this item

Does my Thinkmate GPX-XS12-24S3-8GPU server need any specific firmware revision before I install this 3200 MHz ECC RDIMM kit?

The modules are validated for the Thinkmate GPX-XS12-24S3-8GPU platform; follow the server vendor's firmware update guide before installation.

Can I mix these 128 GB 4Rx4 registered DIMMs with smaller 1Rx4 or 2Rx4 sticks already in the chassis?

Registered ECC RDIMMs of different ranks can share a channel if the motherboard supports mixed-rank population; consult the system manual for allowed slot order.

After powering on, how do I confirm the full 256 GB kit is running at 3200 MT/s with ECC active?

Enter BIOS or use an OS tool such as dmidecode to verify speed shows 3200 MT/s, capacity reads 256 GB and ECC status reports enabled.
