Server memory module for System X

This 8 GB DDR3 ECC module is built for IBM System X servers that require registered memory with error correction. It suits administrators upgrading or repairing compatible rack and tower platforms where data integrity is essential.

Installation notes and common issues

The 240-pin DIMM fits standard DDR3 server slots and seats with a firm, even press until the retention clips click. The most frequent problem is mixing this CL7 1066 MHz stick with faster or non-ECC modules, which forces the channel to run at the lowest common speed or disables ECC entirely.

Deciding specification — DDR3 1066 CL7 ECC

The single figure that determines fit is the rated speed of DDR3 1066 (PC3 8500) combined with CL7 latency and ECC support. If the system board specifies a different speed grade, latency or non-ECC memory, this module will not operate as intended.

Questions about this item

How can I confirm the module is running at 1066 MT/s with CL7 after installation?

Check the BIOS or UEFI memory information screen; it should report DDR3 1066 (PC3 8500) and CAS latency 7 for each installed DIMM.

What comes in the package and is any accessory needed for installation?

The box contains the 8GB 240-pin DDR3 ECC DIMM only; no extra cables, brackets or tools are required beyond a compatible System x server memory slot.

Which capacity version should I choose for a System x server that supports 8GB DDR3 1066 ECC modules?

This listing is the single 8GB 46C7488 module; select the quantity that matches the number of empty slots your server configuration requires.
