512GB DDR4-3200 ECC RDIMM Kit

This NEMIX RAM kit delivers 512GB of DDR4-3200 registered ECC memory across four 128GB modules. It is built for the Thinkmate GPX-XN6-24S3-10GPU server platform. The modules run at 1.20V with CL22 latency and a 4Rx4 rank structure. They use 288-pin RDIMM form factor.

Suited for Thinkmate GPU-Optimised Servers

This memory targets administrators expanding the Thinkmate GPX-XN6-24S3-10GPU. It is not for desktop PCs, laptops or non-Thinkmate servers. Buyers who need unbuffered DIMMs, different capacities or other DDR generations should look elsewhere. Compatibility is validated for this specific system only.

4Rx4 Rank Determines Slot Population

The 4Rx4 organisation decides how many modules each memory channel can accept on the target platform. Server memory controllers limit the total ranks per channel, so this rank count directly governs maximum installed capacity. Verify the platform rank limits before purchase.

Questions about this item

Does this 512GB kit require a motherboard that supports DDR4 3200 ECC RDIMM modules?

Yes, the system must accept 288-pin DDR4 ECC registered DIMMs running at 3200 MT/s with a CAS latency of 22 and 1.2 V operation.

Can I mix these 4Rx4 128GB modules with older 2Rx4 DDR4 ECC RDIMMs in the same Thinkmate server?

Mixing ranks is not recommended; the GPX-XN6-24S3-10GPU memory controller expects matched 4Rx4 modules for stable operation at 3200 MT/s.

How can I verify the kit is running at the rated 3200 MT/s CL22 after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm each DIMM reports 3200 MT/s, CL22, 1.2 V and ECC registered status.
