64GB DDR4 3200 Kit for Thinkmate Workstations

This 64GB kit contains four 16GB DDR4 3200 UDIMM modules built for the Thinkmate VSX-R5-540X1 workstation. It targets IT professionals and system builders who need validated, non-ECC memory for that specific platform. The modules run at 1.20V with a CAS latency of 22.

DDR4 UDIMM Limits on Unbuffered Platforms

Unbuffered DDR4 UDIMMs rely on the memory controller to drive every signal, so total rank count and electrical loading cap practical capacity per channel. This kit uses 2Rx8 organisation across four modules, which fits within typical two-channel limits but may not suit boards that require registered or ECC memory for larger configurations.

2Rx8 Rank Organisation Determines Compatibility

The 2Rx8 rank structure is the single specification that decides whether this kit works in the target workstation. Systems qualified for 2Rx8 UDIMMs at DDR4 3200 will accept it; platforms that require 1Rx8, 2Rx4 or registered DIMMs will not.

Questions about this item

Should I pick the 4×16 GB kit or a different capacity for my THINKMATE VSX-R5-540X1?

The 64 GB kit contains four 16 GB UDIMMs and is the capacity listed for this specific workstation model.

What does the DDR4 3200 CL22 rating deliver in actual use?

The modules run at 3200 MT/s with CAS latency 22 at 1.2 V, giving standard JEDEC throughput for everyday workloads.

Will the 288-pin PC4-25600 interface limit speed on my board?

The UDIMMs are rated PC4-25600; the motherboard’s memory controller will set the final operating frequency.
