Summary: The board is OK, but the BIOS and ASUS support is crap. I tried to update to 1804 using ASUS Flash Utility from Win7 - it got stuck not able to verify after flash. When I rebooted the machine it indeed showed 1804, so BIOS got flashed. However, Windows did not boot anymore, Blue Screen of Death - BIOS is not fully ACPI compliant. Then I tried to downgrade to some earlier version that would boot Windows.
Summary: Like matt87622 I also had problems with this Asus board and others. First board was a Asus P5N32-E SLI. Board died after 2 months of use, no OC'ing and it was well cooled. Asus sent out a broken replacement twice and I had to pay a fee to get a new board instead of a used board as replacement. I bought this board to use as a PC for a family member. Out of the box 1/2 the USB ports don't work and I can't use the PS/2 ports.
Summary: Asus is crap. I have a p5n32-e from the first month i had it the usb acted funny (wouldn't always see devices) Now the pci slots just stopped working and it's unstable. My friend bought a striker extreme and had to rma it 9 times just to get a good one. (there policy is if you have a problem with your new motherboard they send you a broken used board that was supposedly tested) In short do your self a favor and avoid asus.
