Please note that Socket AM2+ AMD Phenom™ II processors cannot be used on socket AM3 motherboards. The socket itself is different and forcing installation of these processors on Socket AM3 motherboards will cause irreversible damage to the processor, and possibly the socket on your motherboard.
Although Socket AM3 processors can be used on Socket AM2+ motherboards (compatibility check with motherboard manufacturer required), the opposite is not possible. This type of damage is not covered under warranty.
Please refer to the Processor In a Box 3 year limited warranty, which states, in part: “This limited warranty does not cover damages due to external causes, including improper use, problems with electrical power, accident, neglect, alteration, repair, improper installation, or improper testing.” See Three (3) Year Processor In A Box Limited Warranty for complete warranty information.
