I just bought a SP 3 from Ebay with a Core i5. The thing would heat up and create noise immediately. Uh oh, I thought. I'm not going to like this device. Then I changed the registry so I could change the CPU max frequency. Also, I researched undervolting and adjusted the voltage to the CPU and the GPU. Now it runs cool and quiet and retains the Core i5 snappiness. Question: Could there be any benefit to undervolting our Atom processors? Do they ever throttle? Could their throttling be prevented by undervolting like on the SP3? Does anyone have any thoughts on this?
