In order to receive support for the latest Broadwell processors, users only have to update their boards to the latest BIOS revisions, which should be available now. But if it isn't, expect it to roll out in the coming weeks, before the official launch of the new processors. For those thinking of upgrading to the latest CPUs, that means, make sure you hang on to your old chip, and do the flash, before selling it off to fund the upgrade. This also applies to anyone looking to pick up a good deal on a Z97 board, with the hope of upgrading to the latest chip. Flash it before you cash it, so you aren't stuck with a chip, but no salsa. That sounded funnier in my head.
To grab your GIGABYTE Broadwell update for your Z97/H97 board, head on over to the GIGABYTE website, look up your board model, and locate the latest BIOS. Or if you have the GIGABYTE update app installed, hit the update button.
