Server memory kit

This OWC kit supplies 128 GB of DDR3L ECC registered memory across four 32 GB modules. It is built for Supermicro SuperServer 1027 and 2027 series systems that require registered DIMMs. The modules will not work in standard desktop computers or alongside unbuffered memory.

ECC registered operation

Error-correcting code and register buffering improve data integrity and allow the platform to address the full 128 GB capacity. The 1.35 V DDR3L voltage reduces power draw compared with standard DDR3 while maintaining JEDEC compliance.

DDR3L 1600 interface

The PC3L-12800 CL11 specification sets the maximum transfer rate and latency for this generation. Systems limited to lower DDR3 speeds will downclock the modules, and boards that only accept unbuffered DIMMs cannot use this kit at all.

Questions about this item

Will the 4Rx4 registered DIMMs need any firmware updates or periodic replacement after installation?

The modules are JEDEC-standard DDR3L 1600 CL11 1.35V ECC registered RDIMMs with no heat spreader; they have no firmware and require no scheduled replacement under normal server operation.

What limit appears first when the 128GB kit runs at full load in a Supermicro 1027 or 2027 series chassis?

The memory controller’s maximum supported capacity and rank-per-channel limit will be reached before the modules’ own 1600 MT/s rating or 1.35V thermal envelope becomes a bottleneck.

How much extra heat and power do the four 32GB DDR3L modules add when the server runs continuously?

Each 32GB 4Rx4 module operates at 1.35V without a heat spreader, so total power draw scales with the platform’s memory controller load rather than adding a fixed thermal overhead.
