(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 1066 MHz memory speed is supported depends on the CPU being used.
(Note 3) Use of a CPU that supports ECC is required if you wish to install ECC memory.
(Note 4) If you are installing one or two PCI Express graphics card(s), be sure to install it/them in the
PCIE_16_A or/and PCIE_16_B slot(s) for optimum performance.
When four graphics cards are installed, the PCIE_16_A and PCIE_16_B slots will operate at up
to x8 mode.
(Note 5) Whether the CPU/system fan speed control function is supported will depend on the CPU/
system cooler you install.
(Note 6) Available functions in Easytune may differ by motherboard model.
(Note 7) The adjustable CPU voltage range depends on the CPU being used.
