My 531h has an Intel Atom N280 inside. I'm running windows 7 at the moment, but my CPU runs only on 1.33ghz. A N280 can do 1.67Ghz. Somewhere on the internet i read that it comes by the fact that N270 is running on bus speeds of 533MHZ and the N280 on 667MHZ. The platform is the same, and wit 533Mhz the N280 only does 1.33Ghz. I surely want to run on 1.67GHZ. How can i do this? When i look in windows --> Intel N280 CPU @ 1.67GHZ 1.33GHZ. In onther words, the CPU is running on 1.33 ghz. How can i solve this problem.
