Some good Info I discovered about ASUS X79 boards: Note
this is for those running windows 8 on their X79 ASUS board (there doesn't seem to be software for the newer version on Intel's website for Win 7, so it looks like this is specific to Win 8).
Here is information on Intel's Management Engine firmware (FW). As of the latest 3305 bios available Jan 2013, ASUS has not updated the management engine FW past 18.104.22.1684, while Intel has moved to version 22.214.171.1246. There is a way to flash the firmware manually to your bios, so I thought I would give it a try, and did so easily.
I've attached all the files you will need. Start by unzipping the attached file to your main C drive. Note this is a "USE AT YOUR OWN RISK"
. Having said that, I tried the newest 126.96.36.1998 version for Z77 which caused the system to restart whenever I tried to shut down, but it still load into windows. So I was able to easily reflash the backup I made of the original, reset bios, and update back to 188.8.131.526, which has been perfectly stable for me.
When you extract the zip file to your c: drive, you will have an MEFLASH folder:
You will need to open the CMD as Admin. to do this, press [windows key+X]
From CMD, type "cd c:/MEFLASH
" minus the quotes
At this point you can backup your original ME firmware by entering the following command: "fptw64 -ME -D backup.bin
" minus the quotes. It will overwrite the backup FW I've already saved from my own bios, which is version 184.108.40.2064
Then flash the new firmware by typing: "fptw64 -ME -F ME8_X79_HED.bin
" minus quotes
There will be a message about no region or something, then it will continue to flash. Once complete, you will have to power down, not just a restart. For Win 8, move the mouse off any active windows and press [Alt+F4] and select shutdown. After the computer restarts, enter bios and verify Management Engine version. It is listed in the upper left corner in the Main bios tab.
And last, get the corresponding Intel management Engine Software:Intel ME 220.127.116.116 Windows 8 x32 and x64
For those wondering how important the ME is:
You need MEI to do "anything related to the CPU under OS".
Want to change the CPU Vcore / multiplier / BLCK.... anything.
Without it, your system may not even be able to display the BCLK right. It is that important.
And to your questions.
1. Yes, it is essential to have MEI installed before installing AiSuite II, else TurboV EVO and Auto Tuning won't work.
2. The reason why it is huge and installs fast is because most of it is windows update related.
3. If you want more performance, enable TPU. For more power saving, enable EPU. For both, enable both.
4. Yes, BIOS settings can override the configuration of these switches.
I scratched this together from a few sites, but this is where I started, and the main source for my info above:
