![]() This difference has a huge impact on battery life and heat, resulting in a lot more battery life without losing performance.Īs technology evolves, the factory sweet point for the majority of CPUs is more personalized. But it actually runs well at 2 GHz with just 1.0750 V. If you are looking for the CoreDuoTemp app Please. Question: Q: Coreduotemp - the two sensors Im running Coreduotemp. You can also choose to display a small floating window that shows temperature, CPU usage, system uptime, and the minimum, maximum, and current CPU frequency. 0.9: Package Installer, main window 33 smaller, no password at launch and no keychain, statistic feature for save computer infos, uptime info, bug. 0.91: Correction of bugs : window position, space folder location (installer and application). ![]() 1.0: CoreDuoTemp become a menubar application. To give you an idea: my CPU with a nominal frequency of 2 GHz normally runs at 1.2625 V. We ran CoreDuoTemp, an application that measures internal temperatures of Intel-based Macs. Hello all Please while you are here click throgh to some of my advertisers this is how I make My Money. CoreDuoTemp is a handy menubar item that monitors an Intel Mac's CPU temperature (as well as CPU load and frequency, if you wish). CoreDuoTemp use SpeedIt, a framework by Increw Team. So the ideal voltage will be a little higher than that point. When you try to run with lower voltage at 2 GHz for example, you will get to a point where your computer will shut down. It's not the same with overclocking or overvolting. It easily undervolts your CPU if you want the frequency. One application that was nice for Mac OS X is CoolBook. You have to check your particular processor. Some of them are sold as ULV (Ultra Low Voltage CPUs) that are expensive to buy because they have better performance for less wattage and less impact on battery life. A percentage of them will work well with lower voltage. Normally higher frequencies need higher voltages - more heat is released, the fans have to work and so on.ĬPUs are not the same when they come out of the factory - they all receive voltage that 99% of them work with. It's not the frequency that "wastes" battery life, but the voltage.
