OWC 8GB DDR3L 1600 CL11 1Rx4 240-pin 1.35V ECC Registered RDIMM for Supermicro A+ 2122TC 2122TG

Server-specific DDR3L ECC RDIMM

This 8 GB OWC module is a 240-pin DDR3L 1600 registered DIMM with ECC and a CL11 latency. It is built for Supermicro A+ Server 2122TC and 2122TG systems that require registered error-correcting memory. The 1.35 V operating voltage matches the DDR3L standard for compatible platforms. It will not work in standard desktop computers.

Registered ECC limits mixing and platform use

Registered ECC memory cannot be mixed with unbuffered modules in the same system. The registered buffer adds one clock cycle of latency, which is normal for server chipsets but makes the module incompatible with consumer desktop chipsets that expect unbuffered DIMMs. The 240-pin DDR3L form factor fits only boards wired for DDR3L registered memory. Buyers who need unbuffered non-ECC memory for a desktop or laptop cannot use this part.

8 GB single-rank registered capacity

The module provides 8 GB in a single 1Rx4 rank, which determines how the memory controller addresses the chips. This rank organisation is fixed and must match the server's qualified vendor list for the 2122TC and 2122TG series. Systems that require a different rank count or higher density per slot will not accept this configuration.
