Turbo Boost Monitor v2.0

This is a cool little Intel app I found.
Interestingly enough I found out that Turbo Boost turns on even when I move the mouse but goes right back to low clock speeds. This constant ON and OFF doesn't this drain power?

Yes, it probably does drain power in the same way that using the gas pedal to accelerate in your car drains more gas than idling or steady state travel. Intel has no motive to drain your battery faster (in fact, much to the opposite) so I would suspect that it's pretty seamless and efficient. You could turn it off in the BIOS (iirc) if you want it to stop.

 

I am just kind of confused. I have the exact same logic as you with the car. Wouldn't it be much more efficient in having an in the middle speed rather than a fluctuation in speeds? I mean maybe this is one of the factors as to why the Core 2 Duo's are more efficient on battery? Just an idea? I could be stupidly wrong

 

Then it would take a month to get from New York to LA instead of a week.

The su7300 consumes 1.05-1.15v, whereas the core i# series consumes 0.725–1.4V. Also note that the core i processors will do more work per-clock (bigger caches, more threads, memory controller on board). So your theory about keeping the turbo multiplier low (or turning it off) would probably go a long way.

 

i going with the gas pedal theory, momentum is not a factor with CPUs. so on/off would be the best.

I think the reason the i5/i7 CPUs use more battery is more from the fact they are still kinda new in architecture and not as power efficent. Core2 has had a nice run and become quite the cool running power saver after several revisions over the years.

in all reality Intel/Dell would have built a much better machine just adding a tad more Vcore and allowing OCing into the 2.0Ghz area on the Core2Duo. (pin moding and battery life on the R1 basically prove this)

But thats marketing for ya...

 

Very interesting take. So I take it you own the R1 and have it pin modded. My first question is, does the pin OC affect battery life? And my second is, Is it possible to pin mod the i7 (or something similar to a pinmod) ?

I ask because perhaps if you can pin the i7, turn off turbo and speedstep, you almost have similar processor to the c2d? or am I wrong?

 

any time you increase the clock cycles at the same given voltage your battery life will reduce. i havent noticed any lesser battery life in my case but im sure its less by some amount.

i dont know about pin moding the R2. but i did hear about someone using software to get it past the 166mhz bios limit.

the i5/i7 is more powerful per clock than the C2D but getting to use less power for the same workload may be hard to do.

 

When cores in a Core i7 or Core i5 CPU enter the C6 sleep state, voltage gets reduced to zero so power consumption of that core also drops to zero. Cores and threads are constantly entering and exiting the C3/C6 sleep states so they can work on the 500+ background threads on the typical Windows PC.

When Windows background tasks need to be processed, it makes sense for the CPU to speed up so it can get the tasks done quickly and then get back into the low power sleep states to maximize C6 residency time as Intel calls it. One fast core that can process background tasks quickly also lets the other core or cores spend a bigger percentage of time in the C6 state where power consumption is minimized.

If you want to compare a CPU to a car then it's best to compare it to a cylinder deactivation scheme. It makes sense to run 1 core or cylinder at a higher load where it is very efficient compared to running all cores or cylinders at part throttle where they are not very efficient at all.

My friend Alex helped me find a trick or two to make ThrottleStop more efficient so the CPU package can spend more time in the energy efficient C6 state. It's a work in progress.

 

Thanks for this, I always wanted to know when turbo mode kicked in.

 

Very insightful thank you unclewebb. I would love to be you're guinea pig for testing if you need one?

 

The method Dell uses to overclock the M11x would lock the VID to .9v. I don't think it's possible to get around that so to get 2Ghz, the chip has to make do with .9v. Not impossible, as I done it, but certainly not common, meaning more dissatisfied owners with their M11x can't handle the 2Ghz overclock.

2Ghz would be killer for the R1- it has more battery life then the R2 still (Discrete mode > Optimus in battery life) and is neck and neck in games performance as the CPU bottleneck is reduced (it still loses in heavily threaded processes such as Cinebench).

There is no need to pinmod the R2 as TME is already unlocked and the all the R2 PLLs are programmable. All the pinmod does, basically, is increase the FSB or allow software to increase the FSB.

It's possible to overclock past the 166mhz BIOS limit for free now, bypassing SetFSB with SetPLL.

 

thanks for infoz

 

Thanks @DavyGT

Too bad theres no guide to running this program I got no idea how to do it...

 

The guide is here. It requires basic command line skills.

 

Not really.. the guide actually makes it more confusing. Ill just stick to BIOS OC I guess...

 

How so? All the commands you're entering are:

Code:

cd C:\setpll
setpll m11xr2              "This lets you check which BCLKs are possible
setpll m11xr2 XXX          "Where XXX is your chosen BCLK to set

 

The ICS is m11xr2? i thought it was numbers and letters

 

The PLL is made by ICS, yes. You can rename the definition file to whatever you want and it will still work.
The reason why it's called m11xr2 instead of ICS9LPRS3XX is because I couldn't take apart my M11xR2 and identify the exact PLL. Probably a 387, 397 or there abouts.

 

How come I can't install this to my m11x-r2? it says your CPU does not support Turbo Boost? U520 i5 CPU here...

 

You have SpeedStep off or TurboBoost off in BIOS

 

Where is it happening? Can we see a screenshot of the problem?
