Speed DDR3 1066 (PC3 8500)

  • 32 GB capacity (2 × 16 GB modules) handles heavy server workloads
  • DDR3 1066 MHz PC3-8500R speed accelerates data throughput
  • ECC registered RDIMM design detects and corrects memory errors
  • 4Rx4 quad-rank x4 organisation maximises density per DIMM
  • 5 V standard DDR3 voltage ensures broad platform compatibility

32 GB DDR3 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR3 1066 MHz registered ECC modules built for servers and workstations. Each DIMM uses a 240-pin form factor, runs at 1.5 V and is organised as quad-rank 4Rx4 with CL7 latency. The memory is tested for reliability in multi-socket environments.

Suited for DDR3 registered platforms only

It fits systems that require DDR3 RDIMM modules with ECC and registered buffering; desktop and laptop boards that accept only unbuffered non-ECC DIMMs cannot use this kit. Buyers needing higher frequencies, lower voltages or unbuffered memory should look elsewhere.

Dual-channel registered upgrade

The paired modules populate two channels on a compatible server or workstation motherboard that supports DDR3 1066 registered ECC DIMMs. The kit adds 32 GB of error-correcting capacity without requiring changes to the existing power or cooling infrastructure.

Questions about this item

My server only takes registered ECC DIMMs — will these 4Rx4 modules work in it?

Yes, these are DDR3 1066 ECC RDIMM modules with registered buffering, designed for servers and workstations that require registered ECC memory.

Can I mix this 32 GB kit with the 8 GB DDR3 1066 RDIMMs already in my system?

Mixing different capacities and ranks is possible only if your server's memory controller and BIOS support mixed population rules; check the system manual for approved configurations.

After installing the 2 x 16 GB sticks, how do I confirm they are running at DDR3 1066 with ECC active?

Enter the BIOS or use a tool such as dmidecode on Linux to verify the speed shows 1066 MHz, the type shows registered ECC, and total capacity reads 32 GB.
