Some Intel B85 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs
My parts list on PCPartPicker is saying "Some Intel B85 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs" i dont know what that means or if it will be a problem. Do I need a different CPU? Which would you recommend for my build? Considering I want to do heavy rendering as well as playing while recording PC games.
Why not just get a newer motherboard chipset? Is there a specific feature on that board you need?
It means that older chipsets may or may not be compatible out of the box with an older chipset like b85. Haswell refresh and devil's canyon were a bit newer, sort of a midway update between haswell and broadwell. Some boards ship with an older bios versions and others ship with an updated bios. In some cases it may need an older original haswell cpu to be installed before updating the bios.
I checked the gigabyte website, it may be fine. For each version of that board (there was version 1.0, 1.1, 1.2, 2.0 and 2.1) they show support for all processors since the same bios revision. It appears they all use the same bios revision so it may be alright. It's not the same with all motherboards, some require a bios update to run the newer cpus.
