Rank 2Rx4

  • ECC registered design protects data integrity in servers
  • 32GB kit with four 8GB modules expands capacity
  • DDR3 1066 CL7 timing meets JEDEC PC3-8500 standard
  • 5V and 1.35V voltage support lowers power draw
  • 240-pin RDIMM form factor fits workstation and NAS slots

Server DDR3 ECC RDIMM kit

This 32 GB kit contains four 8 GB DDR3 1066 PC3-8500 CL7 registered ECC modules on 240-pin DIMMs. It is built for workstations, servers, NAS systems and routers that require registered memory with error correction.

Check platform compatibility

Your motherboard must support DDR3 registered ECC RDIMMs at 1.5 V or 1.35 V and accept 2Rx4 dual-rank modules. Standard desktop boards that only take unbuffered non-ECC memory will not work with this kit.

JEDEC and ROHS compliance

The modules meet JEDEC standards and are ROHS compliant for a warranty-safe upgrade. No heat spreaders are included, so airflow in the chassis must handle the bare DIMMs.

Questions about this item

Does the OWC 32GB kit include everything needed for installation or are extra parts required?

The kit contains four 8GB DDR3 1066 ECC Registered RDIMM modules. No additional memory components are needed; the modules install directly into compatible 240-pin server DIMM slots.

Should I choose the 32GB 4x8GB CL7 kit or a different capacity for my server?

This 32GB (4 x 8GB) CL7 kit suits systems that require registered ECC DDR3 at 1066 MHz. Select it when your platform needs four ranks per channel at 1.5V and you want the full 32GB capacity in a matched set.

What does the PC3-8500 1066 CL7 rating mean once the modules are running in a server?

PC3-8500 indicates a peak data rate of 8500 MT/s at 1066 MHz with CL7 latency, giving low-latency registered ECC throughput for supported workstation and server platforms.
