Cpu turbo not working
Hello,
So I had my laptop alienware M17 with an intel i7-4700MQ CPU @ 2.40GHz (8 CPUs). I just read that the max turbo frequency can go up to 3.4 GHZ so I tried checking if it worked using various monitoring programs including intels own but it never did. I made sure to check at boot menu that the turbo was on but it really does not seem to have any effect. If it can go up to 3.4 GHZ how do I get it to do that when playing games and how can I check it is?
Thank You

Connect AC Adapter, and be sure your Windows PowerProfile is set to High Performance.
That CPUID program isn't the right one to measure individual core speeds, but they have other better ones for that.

My computer is basically connected all the time and is on high preformance for the battery. What program would you recommended me using to measure speed? Also I made sure that heat wasn't an issue as it is set-up on of those external laptop fan and the Measured temperature rarely goes above 80 degrees.

yea that wont show actual speed it wonnt show actual temps etc.. , as game isn't being rendered... I run 2 screens, I watch speeds and temps at all times

are you using 2 screen to see the change or tabbing out? tabbing out will drop cpu speed as game isn't being rendered, ive never successfully got intel to read cpu properly let alone work see, yet ive seen turbo work fine with single thread operations as the single core hit its max speed

i Know and read that before but even when I play games that require better cpu speed such as Arma 3 there is no recorded effect of it. I have the intel program that tells me when the cpu goes into turbo mood and it tells me when it enters turbo mood and it never does.

They used to have a program called Tmonitor, but when you think about it, PerfMonitor2 is better.
