ASUS support has been down for a week for some reason
However, you will just get scripted help unless you ask for level 2 tech
You ignored the points in my post
I said look in CPUID mobo tab to see what you have
You apparently also did not read some of the ASUS posts in the links I gave
Since the earlier SandyBridge P8P67 series bios offerings, subsequent updating to IvyBridge ready 3XXX bios is the most screwed up flash ever, with thousands of endusers bricking their bios, I always advise people seeking help on this to just buy a new offline programmed chip - Its only $16 and comes ready to go with 3602 - unless, that is, you really know what you are doing.

Fwiw:
Bios chips only go in one way
Never install when PSU still plugged in or mobo lights still on (+5VSB is active)
Must gently straighten 8 legs to vertical
Must do
Unplugged PSU CMOS reset greater than 10 seconds after insertion
Then do the press F1 to enter bios setup to reset your config
Of course you should very carefully figure out with CPUID
EXACTLY what mobo, mobo revision and chipset vers you have involved. Its extremely confusing. And since 3XXX bios are Ivy Bridge compatible - immediately after loading new bios chip you should run Intel chipset utility 9.3.XXXX, reboot, then update Intel MEI in dev manager in dev man/system devices to 8.xxxx something. You cant properly run an IB CPU with Vers 8 ME oprom in bios and Vers 7 drivers in Dev Man.
