IBM 16GB DDR3-1866 Registered ECC DIMM

This 16GB DDR3 module runs at 1866 MHz with a CAS latency of CL13. It is a registered ECC DIMM built for System x servers that require error-correcting, buffered memory. The single 240-pin stick operates at 1.50 V and conforms to the PC3-14900 standard. It suits administrators upgrading or repairing compatible IBM rack or tower systems.

Installing the 240-Pin Registered Module

Power down the server and open the chassis to reach the DIMM slots. Align the notch on the module with the key in the socket, press firmly until the retention clips lock, and confirm the module is seated evenly. Registered ECC memory must be used in matched sets per the server’s population rules; mixing registered with unbuffered DIMMs or exceeding the channel limit will prevent the system from posting.

Verify Server Memory Requirements First

Check the System x model’s qualified-vendor list to ensure 16GB registered DDR3-1866 DIMMs are supported at the desired rank count. Confirm the number of available 240-pin slots and the maximum capacity per channel before ordering. The module is sold as refurbished; buyers needing brand-new, sealed stock or a different voltage should source an alternative part.

Questions about this item

How can I verify the module is running at DDR3 1866 CL13 with ECC registered after installation?

Check the BIOS or UEFI memory information screen; it should report 1866 MHz speed, CL13 latency, ECC enabled and registered signal processing for the 00D5047 module.

What comes in the box with the IBM 00D5047 and is anything else required?

The package contains one 16GB 240-pin DDR3 DIMM; no additional parts are needed for installation in a compatible server memory slot.

Which capacity and speed version of the 00D5047 should I choose for my System X server?

This part number is a single 16GB DDR3 1866 registered ECC module; select it when your server requires a 16GB PC3-14900 DIMM.
