Windows 7 - Upgrade/Clean Install

DIGItonium

I got the upgrade media last night and quickly swapped out the slow as molasses hard drive in the Lenovo U330. I did the clean install followed by upgrade install from within Windows before activating the key online. It worked like a charm! The laptop is so much more responsive like a typical desktop.

Ah, I finally had time to dig into Win7 and work on some optimizations. Win7 memory management is definitely much nicer than before. I had SuperFetch disabled in Vista because it kept grinding the hard drive. I did the same with my laptop as well and I've never had any issues. It is also one of the optimization suggestions for users with SSDs.

You can't quite compare airflow and electron flow. The transistor design and construction on various classes of processors are no different. The silicon parts are speed tested, graded, and binned. For example, a 2GHz and a 3GHz CPU can technically be the same design on the same silicon and wafer. The 2GHz part may have been graded to run optimal at its specified clock and voltages. If there is a shortage of 2GHz parts, a 3GHz part can be down clocked (and specify lower operating voltage) and be sold as a 2GHz part.

I never heard of undervolting a processor voiding warranty or starving the processor. Desktop and mobile processors have the ability to change clock speed and voltage requirements on the fly depending on processor load.

True, you can starve the CPU by not feeding enough juice and render the system unstable. Well, that's because that piece of silicon wasn't one of the lucky ones.
