512GB DDR4 3200 ECC RDIMM kit

This kit supplies 512GB across eight 64GB registered DDR4 modules rated at 3200MT/s with CL22 latency. It targets Thinkmate TWX-XS8 tower servers that require ECC RDIMM memory for stable operation. The 4Rx4 organisation and 1.2V voltage match the platform specification. Modules use major OEM DRAM from Samsung Micron or Hynix.

Check motherboard slot count and rank support

Verify the server provides eight DDR4 RDIMM slots and accepts 4Rx4 modules at 3200MT/s. Confirm the BIOS revision listed by Thinkmate for the TWX-XS8-14S3 TWX-XS8-24S3 or TWX-XS8-24S 3.1 models. Ensure the memory controller can address the full 512GB capacity with this rank configuration.

Sustained load behaviour in registered ECC modules

Registered buffers and on-die ECC maintain signal integrity during continuous multi-threaded workloads such as virtualisation or database processing. The 1.2V operating voltage keeps power draw consistent across all eight modules. Rigorous stress testing under load is performed before shipment to validate long-term stability.

Questions about this item

Does the 512GB kit ship as eight separate 64GB modules or must additional parts be purchased?

The package contains eight 64GB DDR4 3200 RDIMM modules; no extra components are required for installation.

Should I choose the 4Rx4 rank configuration or is another rank offered for this capacity?

This 512GB kit is only available in the 4Rx4 organisation; each 64GB module uses a quad-rank x4 layout.

What does the CL22 rating mean when the modules run at DDR4 3200 in a ThinkMate tower server?

CL22 indicates 22 clock cycles of CAS latency at the rated 3200 MT/s speed, giving a baseline timing for ECC registered operation.
