Good evening, I have a new Core i7-based Sandy Bridge machine. The machine was overclocked by the system builders so that it should run at 4.6Ghz when a single core is under load. However, the suggested method for confirming this given by the suppliers was to run Prime95 and CPU-Z - these are Windows applications, whilst I am using a Linux (Ubuntu 11.04) environment. Having done a fair amount of internet searching I'm unable to find a canonical way of confirming in Linux that the "turbo" is taking place when the single core is under load.
This is quite important to me as I'm running computational physics calculations on the machine and need it to be as quick as possible.
Any help would be most gratefully received, please let me know if I've not been clear enough in my explanation.
