Target systems and purpose

This 8 GB DDR3 registered ECC module is built for IBM System x3400 M2, x3500 M2, x3550 M2 and x3650 M2 servers. It suits administrators who need validated memory for these specific platforms.

Build integration

The 240-pin DIMM plugs directly into the supported servers' memory slots and operates at DDR3 1333 (PC3 10600). Registered signalling reduces electrical load on the memory controller, leaving headroom for larger configurations.

Thermals and power

Low-profile construction keeps the module clear of standard server airflow paths. Registered DDR3 at 1333 MHz draws modest power and runs quietly within the chassis cooling design of the listed systems.

Questions about this item

Will the registered ECC design limit how many of these 8 GB modules I can install in an x3550 M2?

Each module is a registered DDR3 DIMM; the x3550 M2 memory controller and BIOS determine the maximum supported capacity and rank population per channel.

How much heat does a single 8 GB registered DIMM add when the server runs 24/7?

Registered DDR3 1333 modules typically draw a few watts each; total thermal load depends on how many slots are populated and the system airflow design.

Which IBM servers are confirmed compatible so I know the module will work without extra parts?

Qualified systems include the x3400 M2 (7836, 7837), x3500 M2 (7839), x3550 M2 (7946), x3650 M2 and the iDataPlex dx360 M2 and M3.
