The one curious thing about this intel motherboard is that, it starts with 1 beep, then the bios page shows up, and then another 1 beep, then the windows loads. Would just like to inform everyone that its nothing to worry about, its just the way this MOBO works. So Chillax guyz… Also it supports DDR3 Ram. Has 2 pci slots and 1 pci express slot.
