3.Insert the module into the DIMM socket and press down evenly on both ends firmly until the DIMM module is securely in place. (The tabs of the DIMM socket will close-up to hold the DIMM in place when the DIMM is properly installed on the socket’s bottom.)

4.Repeat step 1 to step 3 for all additional DIMM modules.

IMPORTANT

*The Opteron features a 128-bit wide DDR memory interface. To take advantage of the 128-bit interface, you must install DIMMs in pairs of two (2). DIMM slots A1 and B1 are paired, and slots A2 and B2 are paired. If you are only installing two DIMMS into a Memory Bank, it is recommended that you install them in slots A1 and B1 to get the full bandwidth.

*To ensure compatibility, only use DIMM pairs of the same exact type and size and made by the same company.
