Hello, I am still going strong on i5 2500k in 2019, mostly playing older games anyway and everyday tasks. Im happy with it. I have it turned on 24/7. It eats about 5€ of electricity per month which isnt much. But i like tweaking so i would like to see how much i can improve this. So i have 2 questions: 1) which settings in bios are the most important to reduce the idle power consumption. I have seen some setups to go as low as 30W. Right now with 8800 gts i am using 100-110W in idle. Will changing those settings affect how soon my pc becomes responsive ? Like if its in idle at lowest multiplier/voltage and i click on a program, will it take longer to open it (meaning cpu will need to get it into gear) because of that ? 2) I have it overclocked to all core 4Ghz right now. But per core seems superior. Tell me if i am right. Lets say we have a fixed voltage, so voltage is out of the equation. We have 2 choices: a) all 4 cores at 4Ghz b) 4 cores at 4Ghz, 3 cores at 4.1Ghz, 2 cores at 4.2Ghz, 1 core at 4.3Ghz Am i right in assuming that with same voltage what u see can be acomplished ? And if it is soo, wouldnt it be great ? That way in single threaded workloads i get 300Mhz more, and if all 4 treads are used, i still have the same 4Ghz i would if i set all 4 cores to 4Ghz ? Am i understanding this right ?
