System-Specific ECC RDIMM Kit

This 64GB kit contains four 16GB DDR4 3200 registered ECC modules built for the THINKMATE VSX-R5-540W3 workstation. Each stick runs at 1.2V with CL22 latency and a 2Rx8 organisation. The registered design adds a buffer that stabilises heavy multi-module loads in server-class motherboards.

Matched Quad-Channel Kit

The four modules are tested together as a single kit so the workstation can populate all four channels with identical timing and voltage. ECC circuitry corrects single-bit errors on the fly, protecting data integrity in long-running compute or storage workloads. No heat spreaders are fitted, leaving the DRAM exposed for standard server airflow paths.

Straightforward DIMM Installation

The 288-pin RDIMMs key into the workstation's DDR4 slots in the order shown in the system manual; no extra cables or firmware steps are required. Builders must verify the board accepts registered ECC memory, as unbuffered or non-ECC DIMMs will not work in this platform. Mixing these sticks with modules of different rank, speed or voltage typically prevents the system from posting.

Questions about this item

Does the kit include a heat spreader that might need cleaning or replacement over time?

The modules have no heat spreader, so there is nothing to clean or replace on the memory itself; just keep the server chassis filters clear for good airflow.

What limits sustained throughput first — the CL22 latency or the DDR4 3200 bus?

The DDR4 3200 bus sets the peak bandwidth ceiling; CL22 latency affects response time but does not reduce the maximum data rate the bus can sustain.

How much extra heat do the four registered ECC modules add when the system runs continuously?

Each module runs at 1.20V without a heat spreader, so the registered ECC design keeps power draw low and the thermal load is handled by normal server airflow.
