Server-grade DDR3 module

This 4 GB DDR3 SDRAM module is built for servers and workstations that require registered ECC memory. It targets system integrators and IT teams maintaining or expanding legacy DDR3 platforms.

PC3-8500 speed rating

The module operates at a 1066 MT/s data rate with a PC3-8500 bandwidth rating. This single speed figure determines whether the part matches the memory bus of the target system.

240-pin registered DIMM

The 240-pin registered form factor fits DDR3 RDIMM slots and presents a 2Rx4 organisation to the memory controller. It frees the builder from sourcing unbuffered or non-ECC alternatives for compatible boards.

Questions about this item

Will the 1066 MT/s speed run at that rate or drop lower in my server?

The module is rated for DDR3 1066 (PC3 8500); it will operate at that speed if the platform supports it, otherwise it downclocks to the highest speed the memory controller allows.

What does the PC3-10600 rating on the label mean for actual bandwidth?

PC3-10600 denotes a peak transfer rate of 10600 MB/s at DDR3 1333; the installed module runs at DDR3 1066, so the practical ceiling is 8500 MB/s.

Does the 240-pin DIMM fit a standard server memory slot?

Yes, it uses the 240-pin DDR3 DIMM form factor used by registered ECC server platforms.
