Re: T420 Turbo Boost not working 1.33 BIOS.

2011-09-08, 16:18 PM

I took some time today to make a brand new windows installation on an external disk, and then boot it from the eSATA slot.

 

The turbo boost works absolutely fine on the vanilla install with and without the chipset drivers, so that must mean that along the way I've installed some driver or another which stops Turbo Boost doing it's thing.

 

I'll reformat at the weekend and post back here if I find out the cause - otherwise i'll mark this as a "solution".....
