I should add that my motherboard was an open box when i bought it so that could very well be the cause of my stuttering/ stability problem cause Ive had performance issues since switching to this board from my old B450 tomahawk as far as i can remember but i'm not 100% its the board, I DO also get micro stutters here and there on my desktop but not too often (i dont usually pay enough attention to tell). HOWEVER, i dont necessarily get performance issues in games that Ive noticed.
My cpu is the 5900x, I did notice however when i disabled SMT mode in the bios my PC didnt do the usual 3-4 second stutter upon booting into windows but it did however cut my logical cores in half from 24 to 12.
16gb ram set to 3200MHz (Setting this to a lower value does not change the stuttering i get)
GPU is a 3080.
For my pc to stutter and lag like this in the bios.. SOMETHING has to be awry and since it is in the bios, it makes me think the board is the issue.
