Very interesting - M4EZ bios 0706 was released on 10/10/11, but was pulled by ASUS very shortly after that --- but, no matter ...
Your M4EZ is shipped with a Sandy Bridge CPU bios ...
... you will need to use the
USB Bios Flashback feature to update to a 3xxx Series Bios version
(3203) for your Ivy Bridge i5-3570K CPU to work.
http://support.asus.com/Cpusupport/List.aspx?SLanguage=en&m=Maximus%20IV%20Extreme-Z&p=1&s=39&hashed...Download bios 3203 from the ASUS M4EZ download page / Bios Tab ...
http://www.asus.com/Motherboards/Intel_Socket_1155/Maximus_IV_ExtremeZ/#download... extract & then copy the 3203
ROM file to an
empty Fat32 USB 2.0 stick - then
rename the 3203 ROM file on the USB stick to
M4EZ.ROM .
Now refer to diagram
"2.3.10 Rear panel connection" in the M4EZ manual :
With your machine powered off, plug the USB 2.0 stick into the ROG Connect port
(#12) in the rear panel ...
... then push the ROG Connect switch/button
(#11) until the switch starts flashing
(the Bios Chip #1 LED on the board will be flashing as well) ...
It will take about 2 to 3 to 4 minutes; or so; for the flash to complete - the ROG switch & the Bios Chip LED will stop flashing when complete ...
... then remove the USB Stick from the ROG Connect port, & power on the machine.
Under no circumstance should you interrupt this "re-start to re-set" process of the bios update ...
... the machine will run through 2 boot cycles, & may even power off & power back on, before it brings you to the
F1 Screen.
AGAIN - DO NOT INTERRUPT this "re-start to re-set" process !!! ... let the machine run through the "re-set" process completely.
Then F1 into Bios, & on the Main Page of the Advanced Mode, you should see that your bios version is now 3203 ...
... & you, & your M4EZ / i5-3570K should be good to go ...
btw - when on the Main Page of the Advanced Mode in the Bios, please take note of the ME Version ...
