32GB DDR3 ECC RDIMM kit

This kit provides 32GB of DDR3 memory in four 8GB modules running at 1066MHz with CL7 latency. It is built for workstations, servers and NAS systems that require registered ECC DDR3 modules. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Thermals and power draw

Each module operates at 1.35V, keeping power consumption and heat output low in normal server workloads. No heat spreaders are fitted, so airflow across the DIMMs handles cooling. The registered design adds a clock cycle for signal stability without increasing voltage.

JEDEC compliance and warranty

The modules meet JEDEC and RoHS standards for a warranty-safe upgrade. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme. The kit is tested in-house to meet or exceed OEM specifications for compatible platforms.

Perguntas sobre este artigo

How do I install the 240-pin DDR3 ECC Registered RDIMM modules, and what step is often missed?

Insert each 8 GB module into the correct server DIMM slots for quad-rank registered memory, then verify the BIOS recognises all 32 GB at 1066 MHz CL7; the step often missed is enabling ECC and registered mode in BIOS before booting the OS.

What maintenance or replacement will the 4Rx8 1.5 V RDIMM kit need over time?

The modules have no heat spreader and no moving parts, so no routine maintenance is required; replacement is only needed if a DIMM fails or the platform is upgraded beyond DDR3 1066.

What limit appears first when the 32 GB kit runs sustained workloads at 1066 MHz?

The quad-rank 4Rx8 organisation and 1.5 V operating voltage constrain maximum memory-controller loading, so the platform’s DIMM-per-channel limit is reached before bandwidth or thermal limits become an issue.
