Asus Maximus VI Hero BIOS update or not?

My PC has been built now for about 4 months. I stumbled upon a BIOS update that I may need to have a small overclock. Thats because my BIOS version is old (Ver 0804) there have been 8 updates since, the new one is (Ver 1504). The 4th update after my current version features support for forth gen Intel Haswell processors.. Which I am using just fine, a i5-4670k in fact.

So I ask do I need to update my BIOS to make my system more stable and will it improve over all CPU performance and overclock-ability?


Thank you for the help.

    yes, I would update your BIOS, you may not notice the difference at all, but it is always best to be at the latest BIOS. I doubt OC will be more stable and that you'll have the ability to clock higher, but efficiency of your CPU more likely.
  2. Ok It wont hurt anything I assume updating the BIOS currently? i just need to unzip the new BIOS update, put it on a zip drive and plug that into the BIOS usb slot on my mobo right?
  3. no damage will be done, it is safe. Flash Your BIOS in BIOS.
