B550 processor paired with Ryzen 1st Generation chipset
You can try the Ryzen 1700 as a temporary solution before purchasing the 4800X or 4900X. While not officially supported, some users have managed to get it to work, especially with the ROG Strix B550-I model.
You had a good idea, aiming for B550 or X570 since they offer superior memory configuration options. It's worth noting the X570-E also backs Gen 1 support, so I'll look into that further.
I’ve gotten some DMs and talked to enthusiasts who’ve tried it out. Some of them have confirmed results on their boards. As a reminder in my original post, I mentioned “I know officially it’s not supported.” I was looking for people who had tested it or read articles confirming the situation.
Likely due to the 9900k requiring more cooling than any standard small ITX setup allows.
I believe checking if a model functions is enough; don't upgrade BIOS just because the fourth generation arrives. It looks like many users confirm ASUS and MSI boards work well, while ASRock seems to have mixed results. You can't always rely on BIOS settings being saved.
