When the X220 first came out, there apparently was a problem where the CPU would throttle down, in some cases getting permanently stuck at 800MHz. This was even reported at Notebookcheck.
I'm looking into getting an X220 with the i7 CPU in order to get USB3, which only comes with that CPU selection. This is still the case, right?
The current i7 CPU has had a 100MHz speed bump since the machine was released. May an X220 with that CPU have throttling issues, or have they all been resolved?
From what I've read it wasn't entirely clear whether this, in fact, happened due to heat related issues at all. Still, there were some posts which, perhaps erroneously, implicated the i7 CPU in particular along with, possibly, using 8GB (two sticks of) RAM, as far as I remember. Is there anything to this?
