Asrock z370 Extreme4 compatibility with i5-9600k

[izzytheasian]

I recently picked up an asrock z370 extreme4 motherboard. It arrived, and I was pleasantly surprised to find it came with BIOS 3.10 by looking at the stickers on the BIOS chipset. There is also a sticker on the front of the box that says it supports the new 8 core processors.
Does anyone know if BIOS 3.10 is already compatible with all 9th gen intel cpus? or do I need a BIOS update? All the sources I have seen point towards it being compatible except for the CPU compatability list on Asrock's website

If it has that bios version then it supports the 9th gen processors.

The only reason I am skeptical is because of the "CPU Support List" found here https://www.asrock.com/MB/Intel/Z370%20Extreme4/index.asp#CPU
It indicates that the 9900k, 9700k, and 9600k have only been supported starting with BIOS P3.20 rather than 3.10
Is this something I should be worried about?

I would not be. I've heard, through several other members on this site, all of whom are veteran builders, that they've managed to POST 9th gen CPUs without even updating to the latest bios version. The chipsets are so similar, and the CPU architectures are practically identical, so you should be able to at least get into the bios in order to update to the latest version especially since the 3.1 version specifically indicates support for the 8 core variants which ARE 9th gen CPUs.

It would certainly not be the first time documentation was wrong though. So that could go either way, but I'm pretty confident that it will work. It might be worth contacting ASRock and putting the question to them though. Either way, since you already have the hardware there is nothing to lose by trying it anyhow.
