I found a local seller offering an MSI Tomahawk B850 Max WiFi motherboard for $80, but only two of its RAM slots are functioning (slots 1 and 2). It comes with a 2-year warranty from a local PC shop. My questions are: will I be able to run it in dual channel mode, and is it worth buying this motherboard?

For $20, sure, but $80? At that price, you might as well get a new one!
Why isn't the seller using the warranty? Seems fishy. If it's legit, he could get a replacement for a cheaper deal.
No, only slots 1 and 2 are in the same channel, so you'd lose 10-20% CPU performance. That's not worth it.
Building a system around a damaged motherboard isn’t worth the savings. You need slots 1 and 3 or 2 and 4 for dual channel to work properly.
Unless it's free, I wouldn't buy it. Sounds compromised. If he can fix it, he should've.
If it's under warranty, why hasn't the seller replaced it? Better to skip this one.
