IBM System x3400 M3 server memory

This 32GB kit contains four 8GB registered ECC DIMMs built for the IBM System x3400 M3 models 7378 and 7379. Each module is a 240-pin DDR3 unit rated at 1333MHz with CL9 timing. The kit is designed for server environments that require error-correcting registered memory.

Registered ECC DDR3 1333MHz

The decisive specification is the registered ECC DDR3 1333MHz interface, which matches the memory controller in the supported IBM systems. Modules are dual-rank 2Rx4 and operate at 1.5V. The server will automatically clock the memory down to 1066MHz or 800MHz depending on the installed Xeon processor and the number of populated banks. Quad-rank DIMM limits also apply per the platform specification.

Thermals and power in normal use

These sticks have no heat spreaders and rely on the server's directed airflow for cooling. Registered buffers add a small, constant power draw compared with unbuffered modules, but the 1.5V operating voltage remains within standard DDR3 limits. Acoustic output is determined entirely by the system fans; the memory itself produces no noise.

Questions about this item

What does the 1333 MHz speed mean once the kit is installed in an x3400 M3?

The server will automatically clock the modules down to 1066 MHz or 800 MHz depending on the Xeon processor installed and how many banks are populated.

How does the PC3-10600 rating limit performance in this server?

The DDR3-1333 modules run at the speed the x3400 M3 memory controller allows; quad-rank DIMMs are limited to 1066 MHz and drop to 800 MHz when two are installed per bank.

What physical slot and form factor do these modules need to fit the x3400 M3?

They are 240-pin DDR3 registered DIMMs, matching the 16 ECC RDIMM sockets in the IBM System x3400 M3 7378 and 7379.
