Up for sale is a used 13900KS. Only used as my nas server cpu (i dont game). It is fully functional. has not been degraded and has had the microcode applied from day one (i bought new in jan 2025 when we already had the micro code fix). I kept a low power limit (120w) the whole time since I was using it as a personal high efficiency nas. The reason for selling is because I moved to xeon for my nas.
