Note
(Note 1) Due to Windows XP 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) Whether 1200 MHz memory speed is supported depends on the CPU being used.
(Note 3) For Windows Vista/XP 32-bit opearation system only.
(Note 4) The DVI-D port does not support D-Sub connection by adapter.

Remark

Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
Most hardware/software vendors may no longer offer drivers to support Win9X/ME/2000/XP SP1/SP2. If drivers are available from the vendors, we will update them on the GIGABYTE website.
