I'm going with another CPU, realized it's the best option. I've purchased a used G4500, there's a shortage of 6th/7h gen CPU's!!
Funny cause after 2 years of not using my mining rig and being lazy and not selling components, I finally sold my G4400 for 25€ just 6 months ago lol
I've bought the 4500 for 52€ used, hope it works ^^
As for MOBO non specific for mining, I had my share of them back in the day never again lol
I returned the CPU and hopefully they reimburse but it's not done deal as with amazon so cross fingers with that too...
I really really appreciate your help, you literally have saved me hours of youtube tutorials and not understanding wtf was going on.
