Capacity 32GB (4 x 8GB)

Struck-through versions exist but are not stocked here.

  • 32 GB capacity across four 8 GB modules for expanded multitasking
  • DDR3L 1600 MHz CL11 speed for responsive server workloads
  • ECC registered design detects and corrects data errors in critical systems
  • 35 V low-voltage operation reduces power draw and heat
  • Validated for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR series

Capacity and fit

This kit provides 32GB of DDR3L memory in four 8GB registered DIMMs built for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained operation

ECC registered design detects and corrects single-bit errors during continuous workloads, while 1.35V DDR3L voltage reduces power draw and heat in server and workstation environments. CL11 latency at 1600MHz delivers stable throughput for long-running tasks.

Installation notes

Install all four modules in matched channels for full capacity; mixing with unbuffered DIMMs will prevent boot. No heat spreader is fitted, so ensure adequate case airflow. Verify the motherboard supports registered ECC before purchase.

Questions about this item

How much power does the 1.35 V DDR3L kit draw compared to standard 1.5 V DDR3 when the workstation runs 24/7?

The modules operate at 1.35 V instead of the usual 1.5 V, reducing per-DIMM power draw and total system heat during continuous operation.

Which motherboard slots and CPU memory controllers are required to use these 240-pin registered ECC DIMMs?

They need a Supermicro SuperWorkstation 7037A, 7047AX or 7047GR platform with DDR3L registered ECC support; standard desktop boards cannot use registered memory.

Can I add this 1Rx4 CL11 kit alongside existing Supermicro MEMDR380L modules that are 2Rx4 or CL10?

Mixing ranks or CAS latencies is not recommended; the system will default to the slowest timing and may disable ECC or registered operation if ranks differ.
