i have a core 2 quad q8400 in task manager it is showing(maximum speed=2.13ghz)but it should be 2.66 ghz

This is normal, speedboost adjusts core clocks based on load to save power when high performance isn't needed. Modern CPUs can boost to 4-5GHz under heavy single-threaded loads and drop to something like 800MHz or even full-stop (sleep) at idle.
but when i play games then also it is not at its full speed
There you gothanks everyone for help actually the problem was my speed step disabled so i re-enabled it and now it is working thanks
Yep, this is why I hate speedstep. The $5/yr saved isn't worth the aggravation.thanks everyone for help actually the problem was my speed step disabled so i re-enabled it and now it is working thanks
Depending on how much you run your system on a daily basis, it can be quite a bit more than $5/year. Also, multiply that by a billion or so total PCs on the planet, that is quite a bit of power in aggregate. Modern CPUs can idle at somewhere in the neighborhood of 15W package power vs 100+W under all-cores load. Having dynamic clocks on modern PCs can quite easily save a whole lot more than $5/year.Yep, this is why I hate speedstep. The $5/yr saved isn't worth the aggravation.

When SpeedStep is working correctly (ex.: not disabled for some random reason), it gives you all the performance the CPU is capable of without pissing away power when it isn't needed. Best of both worlds and it is usually plug-and-play.Energy is a resource, but so is time and money. For me, my time is most important. I'm glad that others think otherwise or a lot of power would potentially be wasted.
I've seen too many instances of it holding back performance like taking forever to throttle up--I don't have time for that because when I need something done, it needs to be done now. And if I don't need it, powering it off is easy enough.When SpeedStep is working correctly (ex.: not disabled for some random reason), it gives you all the performance the CPU is capable of without pissing away power when it isn't needed.

If you are still using a Core2Quad, you aren't in any particular hurry to do anything.I've seen too many instances of it holding back performance like taking forever to throttle up--I don't have time for that because when I need something done, it needs to be done now.

Right because even though everything is twice as fast now, things actually work twice as fast? hardly. Don't confused hardware and software bloat with productivity gains...If you are still using a Core2Quad, you aren't in any particular hurry to do anything.
As for the ramp-up time, Intel CPUs since Haswell can go from sleep to max boost in something like 20 microseconds. That's why Haswell and newer CPUs (ATX 2.3x spec) require PSUs capable of coping with 0-100% CPU load transient at a rate of 10A per 10us.
