256GB DDR4 3200 ECC RDIMM kit

This 256GB kit contains four 64GB DDR4 3200 registered DIMMs with ECC and a CAS latency of CL22. It is built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard and runs at 1.2V using 2Rx4 organisation. The modules are 288-pin RDIMMs without heat spreaders.

Sustained load behaviour

Registered buffering and ECC correction keep data integrity stable during continuous server workloads. The 1.2V operating voltage and CL22 timing maintain consistent throughput without the voltage spikes seen in high-frequency consumer kits. Modules are stress tested under load before shipment.

DDR4 RDIMM interface limits

The DDR4 3200 standard caps transfer rates at PC4-25600, so this kit cannot exceed that bandwidth. Registered DIMMs require a motherboard with registered memory support; they will not function in consumer boards that accept only unbuffered modules. Capacity is fixed at 256GB across the four slots.

Questions about this item

Does the 1.20 V DDR4 3200 kit add noticeable heat or fan noise in a 24/7 server?

The modules run at standard 1.20 V with no heat spreader, so thermal output matches typical registered DDR4; system fan curves will dictate any audible change.

What motherboard feature must the ASUS Pro WS WRX80E-SAGE SE WiFi provide for this 288-pin 2Rx4 ECC RDIMM kit to function?

The board must support registered ECC DDR4 RDIMMs at 3200 MT/s with 2Rx4 organisation and 1.20 V operation across all four slots.

Can the CL22 2Rx4 modules share channels with older DDR4 3200 ECC RDIMMs of different rank or latency?

Mixing ranks or CAS latencies on the same channel is not recommended; the memory controller will down-clock to the slowest common timing and may disable multi-rank optimisations.
