4 GB DDR3 1066 ECC RDIMM for Servers

This 4 GB registered DIMM runs at DDR3 1066 (PC3-8500) with ECC and a 4Rx8 organisation. It is built for server and workstation platforms that require registered, error-correcting memory. The module uses major-brand chips and operates at the standard 1.5 V DDR3 voltage.

Check DDR3 1066 RDIMM support and rank limits

Verify that your system accepts DDR3 1066 registered ECC DIMMs and can address 4Rx8 modules. Confirm the motherboard or server documentation lists PC3-8500 speed and 1.5 V operation. Ensure the 240-pin form factor matches the memory slots and that the platform supports the 4 GB density per slot.

Suits upgrades for Samsung M393B5173EH1-CF8

This module suits administrators replacing or matching the Samsung M393B5173EH1-CF8 part in compatible servers. It is not for desktop boards that require unbuffered non-ECC memory, nor for systems limited to lower rank counts or different DDR generations. Buyers needing higher capacities per slot or faster DDR3 speeds should look elsewhere.

Questions about this item

What is included with the 4GB DDR3 1066 ECC RDIMM module and do I need to buy anything else to install it?

The package contains one 4GB DDR3 1066 ECC RDIMM module with 240 pins; no extra parts are required beyond a compatible DDR3 registered DIMM slot.

How do I decide between the different capacities or ranks listed for this DDR3 1066 ECC RDIMM?

This listing is a single 4GB 4Rx8 module; choose it when your server needs a 4GB registered ECC DIMM at 1066 MHz and has an available 240-pin slot.

What does the PC3-8500 rating mean for actual performance once the module is installed in my server?

PC3-8500 identifies the module as DDR3 1066 with CL7 latency at 1.5V, so the memory controller will run it at 1066 MHz with those timings when the system supports the specification.
