fredp1 Posted March 7, 2013 Share Posted March 7, 2013 Just wanted to share my experience with installing Win 8 64bit Pro on a Dell E6500 laptop. Win 7 ran faster compared to win 8. The windows experience index for the CPU was at 2.4 when win 8 got installed. Found a article that suggested to turn off speedstep in the bios. http://blog.tmcnet.com/blog/tom-keating/microsoft/windows-8-cpu-slow-benchmarks.asp After turning it off, the CPU index jumped to 3.6... 50% increase. The other pc's at home are all i5/7 and they worked fine. It might be a problem with the older cpu's and win 8 not applying the correct cpu multiplier. By turning speedstep off, does that mean the CPU is always running at "full speed". Link to comment Share on other sites More sharing options...
ikon Posted March 7, 2013 Share Posted March 7, 2013 I believe you hit it on the head: SpeedStep allows the CPU to step down when there is less demand. It can increase battery life on laptops and other mobile devices. Link to comment Share on other sites More sharing options...
