Server DDR3 1066 ECC RDIMM

This is a single 4GB DDR3 1066MHz (PC3-8500) registered ECC DIMM built for server and workstation platforms. It runs at 1.5V with CL7 latency and uses a 4Rx8 organisation on a 240-pin form factor. The module carries major-brand chips and is validated as a direct replacement for the listed Dell part numbers. It targets administrators maintaining legacy DDR3 systems that specifically require registered error-correcting memory.

Suited for registered ECC slots only

It fits systems that accept DDR3 1066 registered ECC RDIMMs and will not work in boards limited to unbuffered UDIMMs. Buyers whose platforms demand a different DDR3 speed grade, a different rank configuration, or a non-ECC memory type should select a module matching those exact requirements. The 4Rx8 density also means the motherboard must support quad-rank registered DIMMs at this frequency.

Registered ECC with 4Rx8 organisation

The registered buffer and on-board ECC are the decisive attributes; without both, the module will not post in a compatible slot. Verify that your system's memory list calls for DDR3 1066 PC3-8500 ECC RDIMM 4Rx8 before ordering.

Questions about this item

Will this 240-pin DDR3 DIMM fit my server's memory slots?

The module uses the standard 240-pin DDR3 DIMM form factor, so it fits any server board that accepts DDR3 registered ECC memory.

Do I need to change any BIOS settings when installing this 4Rx8 registered ECC module?

Most servers detect the 4Rx8 registered ECC configuration automatically; the common mistake is mixing registered and unbuffered DIMMs in the same channel.

How long will this 1.5V DDR3 module last before it needs replacement?

The module is built with major-brand chips and tested for server workloads; under normal operating conditions it typically remains reliable for the life of the platform.
