Capacity 32GB

  • 32GB single module expands server capacity
  • DDR3L 1600 CL11 delivers 12800 MT/s throughput
  • ECC registered design protects data integrity in workloads
  • 35V DDR3L operation reduces power draw and heat
  • Validated for Supermicro X9DAL X9DAX X9DB3 X9DBi X9DBL motherboards

Targeted Server Upgrade

This 32GB DDR3L 1600 CL11 ECC Registered RDIMM is built for Supermicro X9DAL, X9DAX, X9DB3, X9DBi and X9DBL motherboards. It serves workstations, servers, NAS systems and routers that require registered error-correcting memory. Standard desktop boards cannot use this module.

Registered 240-Pin Build

The module uses a 240-pin DDR3L form factor at 1.35V with a 4Rx4 organisation and no heat spreader. JEDEC and RoHS compliance ensures a warranty-safe installation. Registered buffering prevents mixing with unbuffered DIMMs, so the memory controller must support registered operation.

Extends Legacy Platforms

It replaces lower-capacity or non-ECC DDR3L sticks in compatible Supermicro platforms, adding 32GB per slot for virtualization or large datasets. The upgrade is worthwhile when the board accepts registered DDR3L 1600 and the workload demands ECC integrity. Buyers needing unbuffered memory or a different DDR generation cannot use this part.

Questions about this item

What does the PC3L-12800 DDR3L 1600 interface cap in real use?

The module runs at DDR3L 1600 with CL11 latency and 1.35V, so the JEDEC standard caps throughput at PC3L-12800 for registered ECC workloads.

What physical slot and clearance does the 240-pin RDIMM need?

It requires a standard 240-pin DDR3 DIMM socket and fits the Supermicro X9DAL, X9DAX, X9DB3, X9DBi and X9DBL motherboards listed.

How is the 4Rx4 registered module installed and what step is often missed?

Align the notch, press firmly until both latches click, then verify the BIOS recognises the full 32GB as registered ECC — skipping the BIOS check is the common mistake.
