  • 256 GB capacity with two 128 GB modules for high-density server workloads
  • DDR4 3200 speed rated at PC4-25600 for fast data throughput
  • ECC registered RDIMM design detects and corrects memory errors automatically
  • CL22 latency at 1.2 V for stable low-voltage operation
  • Validated for ThinkMate TWX-XS8 tower servers including 3.1 models

Capacity and Server Fit

This 256GB kit provides two 128GB DDR4 3200 registered DIMMs for THINKMATE TWX tower servers. It targets administrators who need maximum memory density in the supported 3.1 platform without exceeding the motherboard slot count.

Registered ECC Headroom

The 4Rx4 organisation and CL22 timing at 1.2V deliver 25600 MB/s bandwidth while ECC corrects single-bit errors in flight. Capacity runs out when workloads exceed the physical 256GB limit or when the server memory controller cannot address additional ranks beyond the populated slots.

DDR4 RDIMM Interface Limits

The 288-pin DDR4 RDIMM interface caps transfer rate at 3200 MT/s and requires registered buffering for signal integrity at this density. Systems that only accept unbuffered UDIMMs or operate at lower DDR4 speeds cannot use these modules.

Questions about this item

Will these 4Rx4 DDR4 3200 ECC RDIMMs run with my existing 2Rx4 modules in a THINKMATE TWX-XS8-24S3 tower?

Mixing 4Rx4 and 2Rx4 ranks is not recommended; the motherboard will likely default to the lowest common speed or fail to post. For best stability, populate all slots with identical 4Rx4 modules.

How do I verify the 256GB kit is running at 3200 MT/s with CL22 after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show DDR4-3200, 1.20 V, CL-22-22-22 and ECC registered status for each 128GB module.

Does the package include only the two 128GB RDIMMs or are heat spreaders and cables supplied?

The box contains the two 288-pin DDR4 ECC RDIMM modules only; no heat spreaders, cables or additional hardware are included.
