Server-grade DDR3L kit for Supermicro X9 platforms

This 32 GB kit contains two 16 GB DDR3L 1600 CL11 registered ECC modules built for Supermicro X9DAL, X9DAX, X9DB3, X9DBi and X9DBL motherboards. The 240-pin RDIMMs run at 1.35 V and use a 2Rx4 organisation. They are designed for workstation, server and NAS workloads and will not operate in standard desktop boards.

Steady throughput with registered ECC reliability

Registered buffering and ECC correction keep data integrity intact during continuous multi-threaded tasks such as virtualisation, database serving or long render jobs. The CL11 latency and 1600 MT/s transfer rate deliver predictable bandwidth without the timing variations seen in unbuffered consumer memory under sustained load.

Verify registered ECC support

Confirm your X9-series board accepts registered ECC RDIMMs and check the maximum supported capacity per channel before ordering. This kit cannot be mixed with unbuffered modules and requires a platform that explicitly lists DDR3L registered ECC compatibility.

Questions about this item

Does the 1.35V DDR3L 1600 kit run cooler than standard 1.5V DDR3 when the server operates 24/7?

The modules operate at 1.35V, which is the lower DDR3L voltage, so they draw less power and generate less heat than 1.5V DDR3 under continuous load.

Must the Supermicro X9 motherboard already support registered ECC RDIMMs and 2Rx4 density for this 32GB kit to function?

Yes, the board must accept 240-pin DDR3L ECC registered RDIMMs with 2Rx4 organisation; standard desktop boards that only take unbuffered non-ECC DIMMs will not work.

Can I add these two 16GB RDIMMs alongside existing 8GB unbuffered ECC modules in the same X9DAX system?

No, registered and unbuffered ECC memory cannot be mixed; all slots must use registered RDIMMs for the system to boot and run stably.
