256GB DDR4-3200 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR4-3200 registered DIMMs built for the ThinkMate VSX-R5-540W3 workstation. ECC and registered buffering protect data integrity in continuous server workloads. The modules run at 1.2V with CL22 latency. They are intended for IT professionals who need validated, high-capacity memory for mission-critical environments.

DDR4-3200 registered DIMM limits

DDR4-3200 tops out at 3200 MT/s and the registered interface adds one cycle of command delay. The 2Rx8 organisation caps density per rank at 32GB. ECC overhead reduces usable bandwidth slightly compared with non-ECC equivalents. Systems that require faster transfer rates or unbuffered modules cannot use this kit.

Replaces lower-capacity or non-ECC DDR4 RDIMMs

Upgrading from smaller RDIMM sets or from unbuffered ECC UDIMMs adds capacity and signal stability for multi-socket boards. The jump is worth it when the workload exceeds the current memory ceiling or when registered signalling is required by the platform. Builders needing unbuffered memory or speeds beyond 3200 MT/s must choose a different module type.

Questions about this item

Should I choose the 256GB kit with eight 32GB modules or a different capacity for my THINKMATE VSX-R5-540W3?

The 256GB kit provides eight 32GB modules that fill eight slots at once. If your workstation has fewer than eight free slots or you need less total memory, a smaller kit would be more practical.

What does the DDR4 3200 CL22 rating mean for actual throughput in my workstation?

The modules run at 3200 MT/s with a CAS latency of 22 cycles. In a real machine this translates to a peak transfer rate of PC4-25600, so sustained bandwidth will be close to that figure under load.

How does the 288-pin ECC RDIMM interface limit what I can install?

The 288-pin registered DIMM form factor only fits DDR4 RDIMM slots on server or workstation boards. It cannot be used in standard UDIMM desktop slots or in DDR5 platforms.
