On my I7-4710HQ the default is not 28 but 8 seconds for turbo boost time window
I set it to the highest setting and for me it holds for several minutes ( didnt have the patience to see how long but surely more than 20 minutes ) at 60watts of tdp instead of the default 57 or so.

this question is to G751JT owner:
please tell us about the boot time of your G751JT with and without ssd (please mention ssd type (sata or m.2.))Last edited: Dec 23, 2014 -
8 seconds default is what I would have expected before I saw the 28 seconds default for the 4700HQ, and usually 16 seconds is the doubled time.
But, if Turbo Boost stays on for hours at a time, and nothing drops at 28 seconds for me and 8 seconds for you (you did look at default too?), then maybe it doesn't mean what we think it means?
The Help built-in to XTU (v5.1.1.25) has a number of Time Window definitions but no definition for "Turbo boost Power Time Window" specifically. The definitions that might be close say what we think it means, but as far as performance is concerned, it doesn't seem to matter.Last edited: Dec 23, 2014 -
It seems the initial issues this laptop was having at launch are cooling down a bit, which makes me more confident to buy one next year. Not sure when exactly i'll buy it, but I hope until the end of February and hopefully with a cool discount
Anyways guys, I wish you all a Merry Christmas! -

ok, i know what your confusion is.
The normal turbo multiplier will hold unless your cpu exceeds 47watts tdp or ~94°c , because if it does ,the cpu will throttle. Gaming, and even most benchmarks won't load your cpu that much that it would exceed 47 watts tdp.
Short time turbo window will let your cpu go over the 47 watts with a maximum of 58watts default for 8 seconds, and it will throttle cpu speed so it doesn't exceed 58 watts ,or 94°c.
There is no time window for normal turbo boost, only short term turbo boost.
The reason you don't see your cpu losing speed after 8,28, or whatever seconds is because it doesn't go over 47watts tdp under the load you are putting it on. So short boost window won't matter. It is working under normal boost conditions.
Try loading your cpu with prime95 SMALL FFT stress test. Then it exceeds 47 watts and if it is on the 8 seconds default short boost setting, then it will throttle your cpu clock down after 8 seconds to a clock speed with which it won't exceed the 47 watts normal boost tdp ceiling.
You can check the tdp your cpu works at with hwinfo 64 for example.hmscott likes this. -
so is good to set high value like 1000seconds?
-
You will stay in Turbo Boost and not drop out even after the Turbo Boost Power Time Window is exceeded. The short time turbo doesn't allow you to exceed safe limits for the CPU, and you will drop down in performance if you do.
The effect is that it is a useless setting, and changing it doesn't do anything to change the performance or result of a run. Even if you set the power settings high, the CPU will protect itself and drop out of Turbo Boost as needed to protect itself.
Try it, you won't be able to affect a Prime run, or better yet a task limited run of something similar that can be timed that takes minutes or longer to perform.
Have you done timed runs to see the difference in results for default/8 seconds vs highest setting possible?
Maybe Intel's handling has improved since the last time I tried it, so if you do get a positive result please let me know. I would test it myself, but I can't change the setting on the 4700HQ CPU.
Since it is tunable, I would set "Turbo boost Power Time Window" as you did for maximum limit, increasing the Power settings and let the CPU throttle based on temperature. That should take advantage of the full potential of the cooling system.
Update: Benkeszabo tested and found a small improvement can be made by increasing the Window from default 8 seconds to higher - it looks like 28 seconds as the 4700HQ default is enough, but setting to max 999999 is ok.Last edited: Dec 25, 2014 -
Cinebench r15 multi test:
1.: 37/36/35/35 multipliers, stock voltage, 47watt turbo boost tdp , and 58w short boost tdp, and 8 seconds turbo boost window (so default settings besides the multipliers)
Running the test in these settings results in the cpu working @ 3500mhz and 51,4 watts for 8 seconds then after the short boost ends it throttles to 3200-3300mhz and 46.9 watts tdp for the rest of the test. The score is 637.
2.: 37/36/35/35 multipliers, stock voltage, 47watt turbo boost tdp , and 58w short boost tdp, and 999999 seconds turbo boost window (so default settings besides the multipliers and the boost window).
Running the test in these settings results in the cpu working @ 3500mhz and 51,4 watts for the whole test (60seconds). The score is 674, so a 6% increase in score.
So...running some very cpu intensive tasks will actually show a difference with a higher boost window, BUT only if the task would load your cpu in a way that it would exceed the normal boost tdp threshold of your cpu (47 watts in this case).
As a consequence you probably won't see any results under most games, and even most benchmarks. For example 3dmark11 physics tests only loads the cpu to 45 watts so it won't enter the short term turbo boost settings...evidently it won't have an effect if you change it.hmscott likes this. -

The tdp only really comes into play when overclocking or running a 8 or 9 series cpu.

Usually intel limits each turbo to 10w higher than stock so you go from 47/57 to 57/67 usually. For the 47xx chips that is plenty.
-
the maximum is 50/60 on i7 mobile procesors that are on asus
-
Wow, you guys are getting way better scores than me on the 4710hq.... might have to look over it for some tweaking.
For now, I've UVed with -30mV, and max temps while gaming / full load are below 79C for the CPU, and the GPU does not go above 70C, which is actually quite amazing.
Quick question: does th Asus G751JT have or not Optimus? i've read that it doesn't, does that mean I'm stuck with the dedicated GPU all the time, even on battery?
My questions will start to flow, for the past 6 years I've owned an XPS, so not very familiar with new tech or other brands... -
But, to reiterate, the benefits of Optimus, a few more minutes on battery mode, pale in comparison to the limitations of running all the video out the Intel iGPU instead of directly from the very expensive Nvidia GPU. Optimus isn't worth it.
Briefly, keeping the iGPU in the video chain keeps it on all the time, adding heat to the CPU die/carrier, even when using the Nvidia GPU for rendering.
This raised the G750JM/J S/JZ CPU temperatures to 10c higher than the same 100% usage tests on the G750JW/JX/JH - essentially the same CPU's running the same load, 10c hotter - which caused many to go into Thermal Throttling:
Things to try ~CPU overheating JM/JS/JZ models~
http://rog.asus.com/forum/showthread.php?48594-Things-to-try-CPU-overheating-JM-JS-JZ-models
And, putting the iGPU in front of the Nvidia GPU disables all the video controls and features that the Nvidia GPU would have if directly connected to the displays (internal/external), including higher than 60hz operation, 3D, G-Sync, DSR(?), and color management.
With the new 980m/970m their power uaage is way down from the 700m/800m, so it is less of an advantage to hobble yourself with the very slow Intel Iris GPU.
Remember, the Intel GPU isn't magic, the rendering efficiency of that part isn't any better, and likely worse, than the Nvidia GPU, so it is going to draw the same power for the same performance, so by using less power it is giving less performance. You may be saving some battery time, but the performance will be less too.
The only good comparison I have is a battery test done on the G750JH compared to the same test on a G750JZ, the JZ ran on battery 15-30 minutes longer, an improvement to be sure, but not enough to put up with the limitations of Optimus.
The G751JT/JY don't have Optimus.
The G750JY, just coming out, has Optimus
So you have a choice
It would be fun if someone ran a battery test on the G751JY with Battery Boost vs G750JY with Optimus/Intel GPU, and also compared in game performance of both on battery, to see in this next generation what has changed.
As Nvidia/ATI makes better and better mobile GPU's, with variable de-tuning for battery time vs performance, the need for Intel GPU / Optimus for laptops with discrete GPU's will disappear.Last edited: Dec 27, 2014eleron911 likes this. -
Thank you sir, I've seen your posts on the asus forums also.
The thing is, being out of the loop for so long makes me highly susceptible to lack of info or potential. I've done my research for the laptop, I've already owned and changed a 750JS, which ran much warmer than this one (on average, as you said, +10C) but the 970m is a big improvement to the 870M.
However, I have always undervolted my systems (I've run my X9000 from stock 3.4 Ghz and 1.47V at 3.8 and 1.3V, with temps under 75C) and I'm going to do the same with this laptop, since power usage=temps, which I want to keep as low as possible with this setup.
I will try what settings I've seen here for XTU, for now, -30mV is very stable with all stress tests and benchmarks I've run, but I get a score of under 500, which is disturbing to say the least. I'll do my research and post updates later on.
Thanks for the info so far! -
i had the same on 3 of 5 laptops g751jy...i changed 5 laptops because of the bleed,but the 5th one is good,the temps are good.
i had 2 laptops returned because of the temps too high,about 93proc and 82 video,the 5th one only gets 80proc and 79video -
The temps are ok, highest I've seen for the GPU was 71-72C at an ambient temperature of 25C.
What worries me is this score, I've checked online and others with the same setup hit 700+. I don't know if that affects performance or not... but I want to make sure whether I should keep it or not.
How did you get those temps? I'm assuming your setup is a bit different, I have the JT with the 4710hq and 970m GPU, so maybe I should expect lower temps overall. -

What performance state are you running in? High performance?

If you are getting normal scores in other benchmarks, I wouldn't worry about the XTU score, XTU is great for tuning, but less so for benchmarking, monitoring, etc. It is meant to provide a single base to do the tuning and monitor the results, but there have been issues with XTU scores for a long time.
Again, if you are getting expected scores in other benchmarks, don't worry about XTU benchmark results - it has turned into a rat hole for many.
About a year ago there were still some software incompatibilities, AIDA64 (uninstalled it), spybot (uninstalled for install, then reinstalled), and early on XTU needed a pagefile for full features - Intel fixed that so I am back to running without a pagefile. There were some library requirements, but those should have been resolved as well. For a while there was a bug that some people were getting 50 points less, but that went away as well.
For some, not all, they need to Run As Administrator to get the XTU installer to work.
Another rathole bug was when an XTU version was "causing" low temperature Thermal Throttling in some models, I think it was predominantly the JX. That wasted a lot of time for some, maybe even caused them to return their laptops, but uninstalling XTU and using hwinfo to monitor Thermal Throttling showed there was no problem with XTU uninstalled. A new version of XTU fixed it... detecting a pattern?
I don't think any of those considerations apply any longer, this is new. So I am posting the Intel support, docs, community links, and HWBOT is a partner for the XTU project and has equal or greater support for optimizations and problem support I would go there first - but also check out the Intel support forum.
I don't have the problem, so I can't work on a fix directly, but I encourage you to carry on and do that and post the results here. As long as you feel you are learning keep going, but if it becomes a frustration, drop it for a while.

On the other hand, I wouldn't get caught up in XTU benchmark scoring issues.
There are lots of other benchmarks, and I encourage you to find, install, and test for comparison to assure yourself that your hardware is running fine.
The normal considerations for performance apply to those benchmarks as well as XTU, so as you optimize your Windows configuration across all the benchmarks, improvements for XTU may occur, and a new release of XTU may fix the current incompatibility that is holding your score low.
Over time I have seen people waste way too much time on XTU score / problems, so please don't get caught up in that.
If XTU is working for setting CPU option tuning, that is enough for me.
Tip: The XTU interface app doesn't need to be running to keep CPU options set. I exit the app/systray after I am done with it. Leaving it running affects performance, just like any other app monitoring the system. I also exit Asus Tweak Tool systray apps after boot.Last edited: Dec 28, 2014eleron911 likes this. -

Exactly with benchmarks and information software it's good to have a couple at least to cross reference.
hmscott likes this. -
I had no Asus apps installed, it was a fresh boot, since my purchase was with Free-Dos.
I've repeated the test several times, right after boot, 10 mins after boot, no difference.
I'll stick to XTU for undervolting purposes and try to do the other benchmarks to see if there is a difference.
Thanks for all the input so far.hmscott likes this. -

Try it on high performance. A lot can happen from micro second to microsecond that impacts performance
hmscott likes this. -
Unfortunately, switching to high performance yielded no difference, still 464.
What benchmark recommendations do you have for testing the CPU? I'd like to do the same tests as others with the 4710hq and x37 multiplier for comparison. -
Hello
I just want to ask some questions about G751JT-CH71
1- How many seconds does boot take (time from pressing power key untill desktop appears) ?
2- did you try to overlock the cpu to make sure that it has turbo up to 3.5 GHz?
3- IS sound good and loud ? >> can i watch a movie with 4 friends with loud sound that make us enjoying the movie with a clear and loud sound ? -
1. approx 5 seconds i'd say.
2. It has turbo boost.
3. I never use speakers but they seem good enough to me. -
-
With but without it is quite the same. -
Has anyone managed to disassemble one of these models? Really curious to see the innards.

Asus has drivers/apps for download for the G751's here at a jumping off point for all 3 models:
G751 Support / Download Areas - Newest - has all 3 G751 models
http://www.asus.com/Search/?SearchKey=g751
Asus has a bad habit of not filling out and keeping current the drivers for their hardware, BIOS's are updated in each model area, but new drivers tend to be added to new products with the same hardware, not the previous products
The G750/G751 use similar hardware/chipsets/peripherals so you can pull the drivers from your model area, and then all the other model areas that have newer drivers for your same hardware.
There are some categories where you need to be specific about the exact name of the driver - like Qualcomm / Athereos parts - you may download a driver that looks right, but refuses to install - you got the wrong one.
Use Features and Programs control panel and look carefully at the name and the Version - the Version is the best clue as each model of part follows a different series - except for those that share the same driver package... you will figure it out.
Asus also has central areas for drivers/app support that are supposed to get updated whenever a new product comes out with that hardware - they are good places to scan for newer drivers.

Just found that my screen refresh rate has become 75 hz. That is weird! It was at 60 before. And i don't have other refresh rate option, only 75. Due to a Geforce experience update perhaps? 'Cause i didn't do anything else before? A way to go back at 60?
EDIT: After some research, it is nvidia drivers update. Then it's ok, 75hz is fine ^^Last edited: Dec 29, 2014 -

So it was simply the tdp of the chip holding it back in their tests, that's all you can ask of a stock cpu.
-
Since XTU is so popular these days, I really don't understand why they don't actually use it for testing. I mean, a higher frequency and a lower TDP overall would improve the perception upon the performance of these laptops.
That being said, Have a great New Year's Eve! -

Lowering the TDP will lower the performance further.

Hi,
I'm currently busy purchasing a Asus ROG G751J. The one I'm purchasing doesn't come with an SSD. Will I be able to fit an 2.5" SSD into the Second HDD bay? Does the laptop come with the bay for the second hard drive, or will I have to purchase the bay separately? Does the Hard drives run at SATA 3 speeds, or SATA 6 speeds?
