Server Memory Kit

This OWC kit provides 64GB of DDR3L ECC Registered memory across four 16GB modules. It is built for Supermicro SuperBlade 7127R, 7127RG, 7127RG3, 7142G and 7427R servers that require registered DIMMs. Standard desktop computers cannot use this memory type, and it must not be mixed with unbuffered modules.

Sustained Load Behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running server workloads. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity when all four DIMM slots are populated. The CL11 latency at 1600MHz delivers steady throughput for virtualisation and database tasks.

Thermals and Power

Modules operate at 1.35V, lowering power draw compared to standard 1.5V DDR3. No heat spreaders are fitted, relying on the blade chassis airflow for cooling. The low-voltage DDR3L design reduces thermal output per module, supporting dense configurations in the SuperBlade enclosure.

Questions about this item

How much power does the 1.35 V DDR3L kit draw when the server runs continuously?

Each module operates at 1.35 V, lower than standard DDR3, reducing heat and power draw during 24/7 operation in Supermicro SuperBlade 7127R, 7127RG, 7127RG3, 7142G or 7427R systems.

What must the chassis already provide for these 240-pin registered DIMMs to function?

The server must support DDR3L ECC registered memory, accept 240-pin RDIMMs, and run at 1600 MHz PC3L-12800 with CL11 timing — exactly as specified for the listed SuperBlade models.

Can the 2Rx4 CL11 1600 MHz modules share channels with existing DDR3L registered DIMMs in a SuperBlade?

Yes, provided the existing modules are also DDR3L ECC registered RDIMMs; mixing with unbuffered or non-ECC memory is not supported.
