    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 optimum performance, if only one PCI Express graphics card is installed, be sure to install it in the PCIEX16_1 slot. The PCIEX8_1 slot shares bandwidth with the PCIEX16_1 slot. When PCIEX8_1 is populated with a PCI Express graphics card, the PCIEX16_1 slot will operate at up to x8 mode.
    (Note 4) Available functions in EasyTune may differ by motherboard model.
    (Note 5) Due to the hardware limitation, you must install an AMD AM2+ Phenom series CPU to enable support for Easy Energy Saver.
    Remark
    1. Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
    2. Due to most hardware/software vendors no longer offer support for Win9X/ME. If some vendors still has Win9X/ME drivers available, we will publish on website.
