16 GB registered DDR3 module

This 16 GB DDR3 1066 module uses a 240-pin registered design for HP and Compaq systems. The PC3 8500 rating confirms the rated transfer speed. Registered buffering helps the memory controller manage heavy loads. It is sold as a new component.

Suitable for HP servers needing registered memory

This module fits HP or Compaq platforms that require registered DDR3 1066 DIMMs. Systems that accept only unbuffered memory cannot use it. Builders needing a different speed or capacity must select another part. Compatibility depends on the exact system specification.

Registered DDR3 1066 specification

The registered DDR3 1066 (PC3 8500) specification is the single detail that determines fit. Only motherboards designed for registered DDR3 at this speed will post correctly. Verify the platform manual before purchase. No other memory type will substitute.

商品問答

Will the registered DDR3 1066 modules maintain stability in an HP server running continuous workloads?

Registered DDR3 1066 modules reduce electrical load on the memory controller, helping HP/Compaq systems sustain stability during extended operation.

How much heat and power do these 16GB registered DIMMs generate under all-day load?

DDR3 1066 registered DIMMs operate at standard DDR3 voltage with lower per-pin current, producing modest heat that typical server airflow handles.

Which HP or Compaq models accept 240-pin DDR3 1066 registered memory for this upgrade?

This 500666-B21 kit is validated for HP/Compaq systems that support 240-pin DDR3 1066 registered modules up to 16GB per slot.
