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.

For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.

The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.

The PCIEX16 slot operates at up to x8 mode when AMD CrossFireX™/NVIDIA SLI is enabled.

The SATA2_5 connector will become unavailable when the mSATA connector is installed with a solid state drive.

When a RAID set is built across the SATA 6Gb/s and SATA 3Gb/s channels, the system performance of the RAID set may vary depending on the devices being connected.

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

Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
