32 GB DDR3 1066 ECC Registered DIMM

This Axiom module supplies 32 GB of DDR3-1066 (PC3-8500) memory in a single 240-pin registered DIMM. It targets servers and workstations that require error-correcting code and registered signal processing for stable operation under sustained load.

Practical limits of DDR3-1066 registered memory

The PC3-8500 standard caps data rate at 1066 MT/s with a CAS latency of CL7 at 1.35 V. Registered buffering adds one clock cycle of address-command delay, which can reduce peak bandwidth compared with unbuffered modules at the same frequency. Platforms limited to lower DDR3 speeds will down-clock the module automatically.

Installation and common issues

The 240-pin DIMM fits keyed DDR3 slots and seats with even pressure until the retention clips engage. Mismatched registered and unbuffered DIMMs on the same channel will prevent boot, as will mixing ECC with non-ECC modules. Verify that the system firmware supports 32 GB density per slot before installation.

Questions about this item

Is the 32 GB capacity sold as a single 240-pin module?

Yes, the kit contains one 240-pin DIMM rated at 32 GB, DDR3 1066 (PC3 8500), CL7, 1.35 V, ECC Registered.

Will the DDR3 1066 rating deliver 1066 MT/s in a server that supports PC3 8500?

The module is specified at DDR3 1066 (PC3 8500) with CL7 latency; it will run at 1066 MT/s when the platform enables that speed.

Does the 240-pin DDR3 interface limit bandwidth to the PC3 8500 level?

The 240-pin DDR3 form factor carries the PC3 8500 standard, capping theoretical bandwidth at the DDR3 1066 data rate.
