I7 3930K if ___ cores are active it runs at 3800, if any more are active it runs at 3.2 correct?
So why does mine jump up to 3800 with all 6 cores(and HT) active???
I just want stock for now.
stock. It's totally fine.
When Intel CPU's have Speedstep and Turbo enabled, it changes the clock speed depending on load. All cores are enabled at all times, unless you specify otherwise.
For example, my work PC's CPU (3570k), just sitting on the desktop is running at 1600MHz (1.6GHz). If I start moving the mouse/doing stuff, it goes up to between 1620MHz (1.7GHz) and 1800MHz (1.8GHz), as it's only under a light load, so it doesn't need to run at full whack, so to speak. This is Speedstep
at work, downclocking to save energy/reduce heat when you aren't using it, then clocking back up when you need the processing power.Turbo
on the other hand gives you more performance over the base max clock speed when you need it. For example, if I launch an intensive game, Speedstep will clock my CPU up to 3.4GHz, as that is the CPU's rated speed, then, if needed, Turbo will take over and clock it to anything up to 3.8GHz (Max turbo speed) depending on the load/if it is needed.
Look at the Clock speed/Max Turbo frequency, should help you understand a little more. There is no reason to run at full speed all the time, it'd be a waste, which is why these features exist. Edited by SmokinWaffle - 3/13/13 at 3:25am
