They run at 222mhz. You can up the clockspeed using those other hacks.. but not in SE-B itself. Why would you want to though? When you say run 'slow' do you mean slower than they would be if you ran them off the UMD normally? Yes, I mean that when I'm playing my GTA.ISO, there is a lot of game play lag. However, I just discovered that someone has released a 2.71 SE overclocker, which lets you change the default clockspeed to either 111Mhz, 300Mhz, or 333Mhz. Since Wifi does not work at 333Mhz, I chose 300Mhz, and now everything is running smooth.
