Note	(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) 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_3 slots. (Note 3) Each PCIEX8 slot shares bandwidth with the corresponding PCIEX16 slot (PCIEX8_1 with PCIEX16_1, PCIEX8_2 with PCIEX16_2, and PCIEX8_3 with PCIEX16_3). When a PCIEX8 slot is populated, its corresponding PCIEX16 slot will operate at up to x8 mode. (Note 4) Whether the CPU fan speed control function is supported will depend on the CPU cooler you install. (Note 5) Available functions in EasyTune may differ by motherboard model.
