IBM 16GB DDR3 1066 Registered ECC

This 16GB DDR3 module runs at 1066 MHz with a CAS latency of CL7. It is a 240-pin registered DIMM that includes ECC for error correction. The memory is designed as a system-specific upgrade for compatible IBM servers. It is supplied in new condition.

Suits maintainers of listed IBM System X servers

This module fits the IBM System x3550 M3 (7944), x3850 X5, x3950 X5 and x3690 X5. It is not for desktop PCs or consumer motherboards that require unbuffered non-ECC memory. Builders needing higher speeds or different form factors should look elsewhere.

16GB capacity per module for supported platforms

Each DIMM provides 16GB of registered DDR3 memory at the rated PC3-8500 speed. The registered design and ECC function support stable operation in multi-module server configurations. Total capacity depends on the number of slots populated in the specific server model.

Questions about this item

Will this 46C7483 module work in my System x3550 M3 (7944) alongside existing 1066 MHz DDR3 DIMMs?

Yes, it matches the DDR3 1066 (PC3-8500) speed and CL7 timing of the original memory for the x3550 M3, x3690 X5, x3850 X5 and x3950 X5 platforms.

My System x3850 X5 requires registered ECC memory — does this 16 GB 240-pin DIMM meet that requirement?

The module is registered and includes ECC, matching the registered ECC specification for the x3850 X5, x3950 X5, x3690 X5 and x3550 M3 systems.

After installing the 16 GB DDR3 1066 DIMM, how can I confirm the server recognises the full capacity?

Check the POST memory count or the system management interface; it should report the additional 16 GB at 1066 MHz with ECC active.
