OWC 16GB DDR3L 1600 CL11 2Rx4 240-pin 1.35V ECC RDIMM SuperBlade

16 GB DDR3L ECC RDIMM for SuperBlade

This 16 GB DDR3L 1600 CL11 registered DIMM is built for Supermicro SuperBlade 7127R, 7127RG, 7127RG3, 7142G and 7427R servers. It delivers ECC error correction and registered buffering for stable operation in multi-socket workstations and blade environments. The module runs at 1.35 V and uses a 2Rx4 organisation on a 240-pin form factor. It is not compatible with standard desktop motherboards or unbuffered memory configurations.

Upgrade from smaller or slower DDR3L modules

Replacing 8 GB or lower-capacity DDR3L RDIMMs with this 16 GB stick doubles per-slot density and helps reach higher total memory limits supported by the blade chassis. The jump is worth it when virtualisation hosts, database nodes or render farms hit capacity ceilings and the platform accepts 2Rx4 registered modules at PC3L-12800 speed. Systems already populated with matching 1600 MHz registered ECC memory will integrate this module without timing changes.

Verify blade model and memory population rules

Confirm the exact SuperBlade series number matches 7127R, 7127RG, 7127RG3, 7142G or 7427R before ordering. Check the server documentation for maximum DIMMs per node, required rank population order and whether mixed 2Rx4 and 1Rx4 configurations are allowed. Ensure the chassis power budget and memory-channel layout support the additional registered load. This module cannot be mixed with unbuffered or non-ECC DDR3L DIMMs.
