Asus Updates BIOS for LGA2011: Adds Ivy Bridge-E Support

Asus has released its official new BIOSes for its LGA2011 motherboards, and within these updated BIOSes is support for the new Ivy Bridge-E CPUs. The updates are available for the following motherboards, with the corresponding BIOS number listed:

  • 4301 - P9X79 LE
  • 4301 - P9X79
  • 4301 - P9X79 Pro
  • 4301 - P9X79 Deluxe
  • 4401 - ROG Rampage IV Extreme
  • 4401 - ROG Rampage IV Gene
  • 4402 - ROG Rampage IV Formula
  • 4309 - TUF Sabertooth X79

The updates can be installed in two ways: either through the use of an older CPU or through the use of Asus' USB BIOS Flashback feature in case a non-Ivy Bridge-E isn't available. The BIOS updates are available here or through Asus' Support Site.

    The thing I always find with bios updates to support new cpu's is that you never know when you can buy an updated mobo, I mean if you are upgrading the cpu on the same mobo sure but quite often when you don't it gets annoying.

    Intel Asus motherboards are fairly predictable which cpu will be supported ever since Intel went to there tick tock update schedule. New microarchitecture will need a new motherboards. Motherboards will be updated to support die shrinks versions of a microarchitecture.

    I bet ivy-bridge cpus will post without the update just be an unknown cpu. People still get bent out of shape like we're still in the old days.
