8GB DDR3 1066 ECC RDIMM for HP servers

This 8GB DDR3 1066 (PC3-8500) module is a registered ECC DIMM built for HP server and workstation platforms. It replaces HP part numbers 500206-071, 500664-B21, 516423-B21, 516423-S21 and 519201-001. The 240-pin form factor fits DDR3 slots in compatible systems. It targets administrators upgrading memory capacity in supported HP hardware.

Sustained workload behaviour

Registered buffering and ECC correction maintain data integrity during continuous server operations. The module operates at standard 1.5V DDR3 voltage with CL7 latency. Major-brand chips are tested for dependable performance under load. It is not suited for desktop boards that require unbuffered non-ECC memory or for systems limited to lower-density modules.

2Rx4 registered ECC organisation

The dual-rank 2Rx4 configuration determines compatibility with specific HP memory controllers and maximum population rules. Verify your system's qualified vendor list before purchase. This module will not work in platforms that only accept single-rank or unbuffered DIMMs.

Questions about this item

How much heat and power does this 1.50V DDR3 1066 registered DIMM draw when running continuously in a server?

The module operates at the standard DDR3 voltage of 1.50V and a speed of 1066 MHz; registered ECC DIMMs of this type typically run cool under sustained load because the register buffers the address and command signals, reducing electrical stress on the memory controller.

What must my motherboard provide for this 240-pin DDR3 1066 ECC RDIMM to function?

Your board needs a 240-pin DDR3 DIMM slot that supports registered ECC memory at 1066 MHz (PC3-8500) with a 1.5V supply and a chipset or BIOS that enables the register and ECC functions.

Will this CL7 2Rx4 registered module work alongside existing DDR3 1066 ECC RDIMMs of a different rank or capacity?

Mixing ranks or capacities is often possible on servers that support flexible population rules, but the system will run all modules at the speed and timings of the slowest installed DIMM; check your server's memory configuration guide for approved combinations.
