Targeted Server Upgrade

This 8GB DDR3 ECC Registered RDIMM is built for Supermicro SuperBlade 7126T and 7226T systems. It delivers 1333MHz speed with CL9 latency at 1.5V for compatible server platforms. The module uses a 2Rx4 organisation and 240-pin form factor. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained Load Behaviour

ECC error correction maintains data integrity during continuous operation in multi-socket blade environments. Registered buffering reduces electrical load on the memory controller when all slots are populated. The 1.5V JEDEC standard voltage supports stable performance across extended duty cycles. Mixing with unbuffered DIMMs will prevent the system from functioning.

DDR3 Interface Limits

The DDR3 1333 interface caps bandwidth at PC3-10600 rates regardless of processor capability. Registered design adds one clock cycle of latency compared to unbuffered modules. Capacity is limited to this single 8GB rank configuration per slot. Supermicro part numbers MEMDR380LCL01ER13 through MEMDR380LSL06ER13 are direct replacements.

Questions about this item

How much power does the 1.5V DDR3 1333 module draw when the SuperBlade runs continuously?

The module operates at the standard DDR3 1.5V supply; actual power draw depends on the server workload and the SuperBlade chassis power management.

What must the SuperBlade 7126T or 7226T already have installed for this 2Rx4 registered ECC DIMM to function?

The blade must support 240-pin DDR3 registered ECC memory and have an available DIMM slot; mixing with unbuffered DIMMs is not supported.

Can this PC3-10600 CL9 RDIMM share a channel with older Supermicro memory parts such as MEMDR380LCL01ER13?

OWC recommends identical capacity, speed and manufacturer for optimal performance; mixing different part numbers may work but is not guaranteed.
