512GB DDR4 ECC RDIMM kit for Thinkmate VSX-R5

This 512GB kit contains eight 64GB DDR4 3200 registered DIMMs built for the Thinkmate VSX-R5-540W3 workstation. Each module is a 288-pin 4Rx4 ECC RDIMM tested for stability in enterprise workloads. It suits IT teams upgrading memory capacity in qualified Thinkmate systems.

DDR4 3200 registered ECC limits

Registered ECC RDIMMs at DDR4 3200 require a motherboard and CPU that support registered signalling and error correction. The platform must accept 4Rx4 organisation and 1.20V operation across all eight slots. Systems limited to unbuffered UDIMMs or lower rank counts will not post with this kit.

4Rx4 rank organisation decides fit

The 4Rx4 rank structure is the single specification that determines whether the workstation can address all 512GB. If the memory controller or BIOS caps rank-per-channel below 4Rx4, the full capacity will not be recognised. Verify the Thinkmate VSX-R5-540W3 documentation for 4Rx4 support before ordering.

Questions about this item

Should I buy the 512GB kit or build the same capacity from smaller modules?

The kit delivers 512GB as eight matched 64GB modules, each 4Rx4 at CL22, so the rank structure and timings are identical across all slots without mixing batches.

What does the 3200 rating actually deliver in the ThinkMate VSX-R5-540W3?

The modules run at DDR4 3200 with a CL22 latency at 1.20V; the registered buffer adds one cycle of command delay, so sustained bandwidth matches the PC4-25600 spec once the memory controller trains the ranks.

Does the 288-pin RDIMM interface limit capacity or speed on this platform?

The 288-pin DDR4 RDIMM socket supports the full 512GB kit at 3200 MT/s; the registered design and 4Rx4 organisation let the chipset address all eight modules without reducing frequency.
