64GB DDR4 3200 ECC RDIMM kit

This 64GB kit contains eight 8GB DDR4 3200 registered DIMMs with ECC and CL22 latency. It is built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard and other compatible ASUS server platforms. System administrators and workstation builders who need registered memory with error correction will use this kit.

Sustained load with registered ECC modules

Registered buffering reduces electrical load on the memory controller when all eight slots are populated. ECC detects and corrects single-bit errors during continuous operation. The 1.2V operating voltage and CL22 timing deliver stable throughput for virtualisation, rendering or database workloads that run for extended periods.

288-pin RDIMM form factor without heat spreaders

Each module uses a standard 288-pin DDR4 RDIMM connector and has no heat spreader, allowing tight spacing in dense server chassis. The 1Rx8 organisation fits the motherboard's memory topology for eight-channel operation. Builders who require taller heatsinks or liquid-cooling blocks should verify clearance before installation.

Questions about this item

How much heat does the 1.2 V 3200 CL22 kit produce when running continuously?

The modules operate at 1.2 V with no heat spreader, so they run cooler than higher-voltage or overclocked DDR4 but still generate measurable warmth under sustained server loads.

What must the motherboard provide for these 288-pin ECC RDIMMs to function?

A DDR4 RDIMM slot that supports registered ECC memory at 3200 MT/s and 1.2 V, with the correct BIOS to initialise the 1Rx8 organisation.

Will the 3200 CL22 registered ECC modules down-clock to match slower DDR4 ECC RDIMMs already in the system?

Yes — JEDEC DDR4 RDIMMs negotiate a common speed, so the 3200 kit will run at the highest frequency all installed modules support.
