ECC-registered DDR3 kit delivers 128 GB across eight 16 GB modules at 1333 MHz CL9 for compatible servers and workstations
Capacity 128GB (8 x 16GB)
Rank 2Rx4
This OWC kit provides 128GB of DDR3 server memory across eight 16GB RDIMM modules. It is built for workstations and servers that require ECC registered DIMMs. The kit will not work in standard desktop computers that only accept unbuffered memory. Mixing these registered modules with unbuffered DIMMs is not supported.
The modules run at DDR3 1333 (PC3-10600) with a CAS latency of CL9 and operate at 1.5V. Each DIMM uses a 2Rx4 organisation and fits a 240-pin DDR3 slot. ECC registered memory of this type cannot be used in platforms that only support unbuffered or non-ECC DDR3. The registered buffer adds a clock cycle, so the memory controller must support registered DIMMs explicitly.
All eight modules are identical, so any supported slot order works. Ensure the server or workstation manual confirms support for 16GB registered DIMMs and for the total 128GB capacity. A common issue is populating slots in a sequence the firmware does not recognise, which prevents the system from posting. Verify the qualified vendor list for the exact platform before installation.

The 128GB kit supplies eight matched 16GB modules tested together, so timings and voltage stay identical across all slots — mixing separate kits can introduce subtle timing mismatches that cause instability in registered ECC systems.
PC3-10600 means a peak transfer rate of 10600 MB/s per module at DDR3 1333; with eight modules populating all channels the server can sustain that bandwidth across the full 128GB capacity for database buffers or virtualisation workloads.
The 240-pin DDR3 registered ECC form factor fits only server and workstation boards that support registered DIMMs; it will not work in standard desktop boards, and it cannot be mixed with unbuffered DDR3 modules.
