Works good with fx8350

Got this in october 2013 so far been ok but first time i started corrupted windows 8.1 and could not get in to the system because of bsod so had to put a fresh copy back only advice i would have is make sure you have a back up disk before turning the system on for first time



Purchased one of these babes a month ago for my new build and i am not disappointed with it.

Motherboard is rock solid and built to a really high standard using high spec materials and components and it shows as the product looks beautiful. Installation was a breeze, standard ATX setup with 9 mounting points onto your case. CPU installation is as per usual, really easy to remove the shipped CPU cooler mounting brackets for fitting an after market cooling solution. Standard RAM sockets but the single sided release mechanism on the RAM makes installation much easier, especially when your case is vertical Position of the PCIe x16 slots is fine too, no huge gap between them so there's not as much room between two cards however it means your second card isn't inches away from the bottom of your case and all the internal header locations on the board are perfect, not to close to other components so plugging everything into the board is easy too. 2 handy features are the MEMOk button which apparently allows the board to boot any RAM in failsafe mode (though i have had no !
need to test this out) and the QuickBIOS button which boots the system up and enters UEFI BIOS straight away (it also has a header that you can connect your reset button to so a press boots straight into BIOS rather than resets your system). Finally is USB Flashback which allows you to flash the system UEFI BIOS without anything other than a PSU, simply DL the BIOS file, rename it and stick it on a FAT formatted USB stick, plug it into the allocated slot and press the USB Flashback button (i have read comments on the internet that although this does flash the bios it actually flashes the second bank then flashes over the first bank on next boot which makes it kinda pointless, again not tested it myself)

The UEFI BIOS is simply amazing, so easy to use and a joy to look at too, all options are easy to navigate too and the board OCs like a dream, i got my FX8350 running at 4.8 with no more than a VCore bump and enabling loadline.

Finally all the windows 8 features work great, Fastboot allows my Windows 8.1 setup to boot from power button press to logon screen in 10 seconds, UEFI mode for Windows is a chore to setup but that is because of MS and Windows rather than the board but once you format your HDD in GPT mode that works great too and Secureboot has simply worked OOTB from the first UEFI install i did.

All in all this is a top quality board, i see no reason to purchase the Formula Z over this, save the



Amazing board, the UEFI is really easy to use and overclocking is amazingly easy. Well worth the money. Highly recommend
