As a certified technician that motherboard also have editions, Without change in model name, But its peoples luck they get good quality of motherboard or not, I try to test in TX Pro motherboard, it dont support more than 233Mhz, but after jumper setting i make it able to go upto 450mhz, and speed is also better. Same thing i do it in other tx pro model but it does'nt work, because of some changes in motherboard, but models are same, but one support higher processor speed and one does'nt
