Server DDR3 ECC Registered kit

This 16GB kit contains two 8GB DDR3 1066 modules built for registered ECC server platforms. The PC3 8500 speed rating matches legacy enterprise memory channels. It targets administrators maintaining or expanding compatible 240-pin DDR3 systems.

4Rx8 rank and registered buffer

Each module uses a 4Rx8 organisation with an on-board register that reduces electrical load on the memory controller. ECC circuitry detects and corrects single-bit errors to protect data integrity. The registered design allows higher total capacity per channel than unbuffered alternatives.

240-pin DDR3 form factor

The standard 240-pin DDR3 layout fits approved server DIMM slots without adapters. Black Diamond Memory tests every module on enterprise platforms and guarantees compatibility across a wide range of validated configurations. The kit is new and ready for immediate deployment.

Questions about this item

Will the 240-pin DDR3 modules need replacement if the server platform is upgraded later?

The modules are DDR3 1066 Registered ECC, so they only fit platforms that support that generation and pin count.

What limits sustained throughput on this 4Rx8 kit?

The PC3 8500 rating sets the maximum bandwidth at 1066 MT/s, which becomes the bottleneck under continuous load.

How much heat and power does the 16 GB Registered kit produce all day?

Registered ECC DDR3 1066 modules draw standard voltage for this speed and rank, with heat spreaders managing thermals during 24/7 operation.
