256GB DDR4 ECC RDIMM kit for Thinkmate servers

This 256GB kit contains four 64GB DDR4 3200 registered DIMMs built with ECC and a 4Rx4 organisation. It is intended for Thinkmate rackmount servers that require registered error-correcting memory for stable operation under sustained workloads.

Verify DDR4 RDIMM slots

Confirm the server motherboard accepts 288-pin DDR4 registered modules and can populate four slots with 4Rx4 density at 1.2V. The system BIOS must recognise the full 256GB capacity and the target platform must be listed in the compatible Thinkmate models.

Samsung Micron Hynix chips on bare green PCBs

Major OEM DRAM from Samsung, Micron or Hynix is assembled without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM edge connector seats directly into registered DIMM slots, and the kit ships as a matched set of four modules for consistent timing across all channels.

Questions about this item

Does the kit include four 64 GB modules or must I buy them separately?

The kit contains four 64 GB modules for a total of 256 GB; no additional modules are required.

Should I choose the 4Rx4 256 GB kit or a lower-capacity option for my Thinkmate server?

Select the 4Rx4 256 GB kit when the server supports quad-rank registered DIMMs and the workload needs maximum capacity per slot.

What does the DDR4 3200 PC4-25600 rating mean for real-world throughput in a Thinkmate rackmount?

The modules run at 3200 MT/s with a peak transfer rate of 25600 MB/s per channel, and CL22 latency is typical for registered ECC DIMMs.
