CPU Sockets

This motherboard is equipped with two types of CPU sockets. You may choose to
install either 939-Pin CPU (AMD Athlon 64FX) or 754-Pin CPU (AMD Athlon 64) into this
motherboard. However, to avoid instability and damage to the system, please do not
install both of them into this motherboard.
Important: If you install a 939-Pin CPU into this motherboard, it is necessary to
adjust the setting of J1 / J2 / J3 / J4 / J5 / J6 / J7 Jumpers by shorting
pin2 and pin3 of all these seven sets of jumpers. These jumpers are set
to support 754-Pin CPU by shorting pin1 and pin2 by default. Please
refer to the figure below for these jumpers' location on the motherboard.
