Inaccurate core speed

Last response: in CPUs

- i5 750, turbo boost enabled
- sapphire HD5770 vapor-x
- Asus AI SUITE comes with mobo driver disc



I got a few questions to ask, about inaccurate monitor and temperature.

First, these 3 monitor softwares shown different value.. why? :pt1cable: 
cpu-z > around 3200
real-temp > around 1400
asus ai suite > around 2700


Second, are my processor and gpu's temperature fine?
I didn't off them a week since purchase, will continue for years.


Last, does intel speedstep, turbo boost, c-state bring more heat to cpu?



Thanks in advance for helps!

i think the temps are ok

Not too familiar with Intels, but do you have something that is like the Cool n Quiet technology with AMDs that throttles the CPU down when it isn't doing much work? I'm wondering if that's what you are seeing here.

I know with the AMD, if I enable Cool n Quiet, I'll see my speed go from 2.8 ghz down to 803mhz, especially when the system isn't doing anything.

Have you tried running all three monitoring programs at once to see if they match at any time? I think what you are seeing is the system increasing or deducing the amount of power the CPU needs to run at dependent upon the work it's doing at that time.

Turboboost is likely kicking the cpu to 3.2 when CPUZ is running

asus is seeing the stock speed

real-temp is likely seeing the speed step reduced speed.

None of this is a problem. But it is odd the way each utility is creating a different cpu state.

Yes, your temps are all very good.

No. In fact, they help lower it.

Thanks, it will be better if you guide me some references.

You've recorded the CPU speeds at different times when your CPU was under different loads.

Run all of those programs at the same time with prime95 running.

Don't forget this part, 'while using Prime95'. This is a stress test that will max out your CPU usage.

Its odd all 3 are showing different things, especially considering most of those things are updated on the fly.

However, like has been said all of those readings correlate properly to your CPU.

Like blue said, try running Prime 95 in the background and post your new readings.
