Capacity and target use

This 16 GB DDR3 module is built for servers that require ECC registered memory. It suits administrators maintaining or expanding compatible IBM System x3650 M3 rack servers.

Speed and signal limits

The module runs at DDR3 1333 (PC3 10600) with CL9 latency. Registered buffering adds a clock cycle for address and command signals, so the memory controller must support registered DIMMs to operate at the rated speed.

Compatibility checks

Verify that your server accepts 240-pin DDR3 registered ECC DIMMs and that the BIOS or firmware recognises 16 GB modules. Systems limited to unbuffered memory or to lower maximum capacities will not post with this module installed.

Questions about this item

Which capacity version of the Axiom 49Y1563-AX should I choose for my server?

The module provides 16GB per DIMM; add multiple units to reach the total memory your IBM System x3650 M3 supports.

What does the 1333 MHz speed mean when the module is installed?

The DDR3 1333 (PC3 10600) rating shows the module runs at 1333 MHz with CL9 latency when the server’s memory controller is set to that speed.

How does the 240-pin DDR3 registered interface affect what the module can do?

The 240-pin DDR3 registered design adds a register between the DRAM and the memory controller, allowing the system to populate more slots per channel while running at 1333 MHz CL9.
