1. 4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory (Note 1)
2. Dual channel memory architecture
3. Support for DDR3 2000(O.C.)/1866/1600/1333/1066 MHz memory modules (Note 2)

2. Support for RAID 0 and RAID 1

South Bridge:

1. Up to 14 USB 2.0/1.1 ports (8 ports on the back panel, 6 ports available through the internal USB headers)

2 x Etron EJ168 chips:

1. Up to 4 USB 3.0/2.0 ports (2 ports on the back panel, 2 ports available through the internal USB header)

VIA VT6308 chip:

1. Up to 2 IEEE 1394a ports (1 port on the back panel, 1 port available through the internal IEEE 1394a header)

(Note 1) Due to Windows 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than 4 GB.

(Note 2) To support a DDR3 1866 MHz (and above) memory, you must install an AMD AM3+ CPU first.

(Note 3) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots.

(Note 4) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.

(Note 5) Available functions in EasyTune may differ by motherboard model.
