Clevo P150EM not turbo

The p150em does not turbo when playing games so the cpu performance is not so great anyway to make it do this?

 

I will explain this. It will turbo if:
- the system needs extra processing power
- there is enough thermal headroom for it to turbo
- applications use less threads

Does it turbo outside of gaming?
Like, if you open Photoshop or something heavy, does it turbo then?
If it doesent, then check the temps.
It needs to be less than 70'C for it to turbo more often.

Also, ThrottleStop can force a turbo boost, AND it will be safe, since Intel CPU's (so I was told) will manage their clocks if temps get too hot, so it won't be damaged.

Clevo has some precautions in place, limiting turbo boost to some extent (at least in the W-series).
Not sure about the EM's, though.

 

Well the same bug I found on my P150EM, ThrottleStop is a must if you hold a P150EM, reason being Turbo Boost gets turned off when dGPU is powered on. P170EM doesn't seem to have this problem though.

 

Err it should work just fine, check temps.

Turbo is also reliant on power consumption.

 

I think if you look around this forum turbo is disabled as soon and a dGPU is turned on regardless of what the cpu tdp is at and temps are try it, run prime 95 and then run the gpu test in GPU-Z it will clock straight down to you base clock speed.

Would flashing the p170em bios stop this is it possible?

 

I'm running a P150EM with a 7970m and a 3610QM and I can say that Turbo Boost does work when using my dGPU. As expected, I experience a 33x multi in single core benchmarks, 32x e dual and 31x with all cores active. I am running the latest P150EM Clevo BIOS.

 

When playing Skyrim my CPU mostly runs at the expected turbo clock speed. I'm not sure why everyone is suddenly proclaiming that turbo doesn't work with the P150EM. By the way, ThrottleStop doesn't work in any way for me.

 

This is a measure used in the 11 inch model but not the 15 or 17 inch versions.

I remember my 3610qm being maxed out turbo in all my games on the original bios.

Prime tends to lower the speeds by itself since it creates s huge increase in tdp.

 

I think most people assume that Turbo Clocks are only the maximum clock (for instance, for my 3610QM it's 3.3GHz max). However, any clock over the stock clock is technically Turbo Clock (for me, anything above 2.3 GHz). Moreover, the maximum clocks depend on the number of cores in use. Honestly, IMHO, must people just panic when they don't see THE maximum clock in CPU intensive games, such as BF3 and the likes.

This, however, doesn't mean people, unlikely as it may be, cannot experience Turbo Boost issues. But generalizing to "using dGPU breaks Turbo Boost" is generalized non-sense. No offense intended!

 

I can assure you it does not turbo when using the dGPU, forcing it to using throttle stop bags me another 9-10fps in ARMA 3

 

So you are saying it is stuck for you at stock clocks? 2.3 Ghz? That is in fact very odd. Can't say that I have experienced that. Do you have the chipset driver correctly installed?

 

Screenshots of intel xtu info graphs would help.

 

it works for me.
I played Heart of the swarm and it needs a high cpu frequency for 2 clock and ran on ultra graphics by the 680m.
my intel xtu certainly shows the cpu turbo boost works for me or else I won't get ~27 fps in late game battles.

 

Meaker, what did you mean when you mentioned the original BIOS? What does upgrading the BIOS do?

 

Well you could try this, first exit ThrottleStop, run MSI Kombuster (set kombuster to use nvidia gpu inside nvidia panel) and then while MSI Kombuster is running, launch Prime95 and stress CPU,

My P150EM has been flashed into a P170EM but without ThrottleStop it still won't turbo. Not like there's a problem since I've been using ThrottleStop since like early releases.

 

its not stuck at 2.3 as its normal clock is 2.7Ghz it will turbo fine but as soon as anything using the dGPU comes on it will go back down to 2.7Ghz and stay there.

 

Went to a P170EM bios, unlocked XTU and had a 3740qm at 3.9ghz

 

I tried a P170EM BIOS seems to make my CPU temps higher.

Also XTU never seems to save the CPU overclock after a restart it will save memory clocks and timing but not the CPU multi.

 

Very odd, it did with mine, make sure you have the latest version and that you are not getting any instability which would cause it to reset.

 

I also now ran Heaven 4.0 and i get 6-8FPS ? this laptop is driving me nuts it performs worse than a m14x cause of this cpu not turboing and GPU throwing wobblies every few minutes

Ran 3DMArk 11 and got a score of 6315 so maybe heaven 4.0 is being a bit weird.

ill run this now with throttle stop enabled and see the score.

 

Either something is setup wrong or you have a hardware fault somewhere.

 

Did you put the Clevo Control Center to "High Performance" mode?

 

Yes games seem to be working fine and 3DMark runs fine maybe its an issue with the Nvidia drivers 314.7 and Heaven 4.0.

Back to the really annoying think here is the fact the CPU defiantly stops turbo when playing a game or using a program using the dGPU, is there a way in a modded BIOS to Enable TURBO pernamently like Throttlestop with like FN +8 thats be like the best thing ever cause of right now my old M14x R2 CPu runs fast then my P150em cause of this issue.

It turbos fine normally as long as the dGPU is off, Throttlestop does force it to turbo when the dGPU is on.

Ok edit i ran the game in windowed mode and watched CPU-Z it was flicking between 2.7 and 3.5Ghz every second, turning on Throttlestop made it stay 3.5Ghz constant.

maybe its not disabling turbo when the GPU comes on, however it doesnt keep it at Turbo clocks anywhere near as long as my m14X that stay at its turbo clocks nearly all the time in game and thats cooling a CPu and GPU on the same heatsink.

 

Max turbo clocks aren't kept constantly. It clocks up to maximum multiplier for a few seconds then it decreases. It has been like so in every iteration. ThrottleStop helps extending this period.

Actually all you need to do is raise the #1 package power limit to 65 or higher and disable limit #2 so the CPU can never reach it, that way you get max turbo clock kept constantly. For P150EM users to do this is going to require cross-flashing.

Because 3610QM under full load with the iGPU running in idle mode won't exceed 45W, a 3720QM or 3740QM under full load is going to reach 50W and the #1 package limit for 3720/3740QM is 45W that's why you are seeing it quits turbo every 16 seconds and Turbo is like full time on your M14X R2.

 

So turbo works fine for me because I have a 3610QM?

And Meaker, I meant how would upgrading the BIOS change anything in terms of the 3610QM performing. I'm not talking about cross flashing, but just upgrading to a newer BIOS. You said you remember playing with the 3610QM maxed out on the original BIOS. Would a newer BIOS version cause issues?

 

this is interesting. is there a guide for cross flashing the bios?
I got a 3840qm and I would like to have every single bit of juice squeezed out

 

I crossfalshed and XTU wouldn't keep the setting i put in would reset all the setting i put in bar the tdp and ram timing everything else was reset each boot.
