Yes the mod in question will require a pro with a rework station. However the Trusty and DreamX boxes are damn near impossible to find today and N64freak seems no longer does 1.4Ghz mods only 1Ghz and even then often times he declines to do the mod. So having another avenue to go down with this will be ideal even if costly initially. I would really to have this as a dev box with my "stock" console for playing games and the CPU/ram modded one for testing etc.
Hello,
Newb here has anyone ever used this?

According to the forums here

It was possible to modify CPU speed. I have a hard time believing this since all the mods I have seen on this recently have involved a TSOP flash.
