256GB DDR4 ECC RDIMM kit for Thinkmate servers

This 256GB kit contains four 64GB DDR4 3200 ECC registered DIMMs validated for Thinkmate STX-TN-XE36-24S3 and STX-TN-XE24-24S3 NAS servers. The modules operate at 1.2V with CL22 latency and use a 4Rx4 organisation. They are built for IT professionals who need maximum registered capacity in these specific platforms.

Registered DDR4 3200 limits capacity per channel

DDR4 3200 registered memory tops out at 64GB per dual-rank module, so a four-slot channel reaches 256GB with 4Rx4 DIMMs. The 288-pin RDIMM form factor prevents installation in desktop UDIMM slots. Systems that require load-reduced or unbuffered memory cannot use this kit.

4Rx4 rank layout decides motherboard compatibility

The quad-rank 4Rx4 organisation places a heavier electrical load on the memory controller than dual-rank alternatives. Thinkmate STX-TN-XE36-24S3 and STX-TN-XE24-24S3 platforms must explicitly support 4Rx4 registered DIMMs at 3200MT/s. Boards limited to dual-rank or single-rank populations will not post with these modules.

Questions about this item

Should I choose this 256GB kit or look for a smaller capacity for my ThinkMate server?

This kit provides 256GB total across four 64GB modules, filling four DIMM slots. Choose it if your ThinkMate STX-TN-XE36-24S3 or STX-TN-XE24-24S3 supports 4Rx4 registered DIMMs and you need maximum capacity.

What does the DDR4 3200 CL22 rating actually deliver in my ThinkMate NAS?

The modules run at 3200 MT/s with a CAS latency of 22 cycles at 1.20V. In your ThinkMate server the memory controller will operate them at the highest speed the platform allows, which may be 3200 or a lower supported JEDEC frequency.

How does the 288-pin RDIMM interface and 4Rx4 organisation affect what I can install?

Each module is a 288-pin DDR4 registered DIMM with a 4Rx4 rank structure. Your ThinkMate motherboard must support 4Rx4 registered ECC memory; the registered buffer and x4 chip organisation are required for compatibility with these specific NAS models.
