4 Asus G750 JM's and now on second JS

[dblkk]

Hey guys, I'm sure most of you hear have seen and heard my posts before. Mainly reguarding ridiculous temps while rendering. 100-105 c with thermal throttling on at least 2 cores.

Well, just and I mean just got my replacement JS model from amazon via ups.

Just signed into with live account and letting windows do its thing quick. Then will d/l intel extremem tuning utitlity, and stress test this, while I download sony vegas 12 pro and cyberlink powerdirector 12. Seeing as how all laptops before ran hot, yet acceptable during stress, it was the rendering that pushed high and throttling.

Fingers crossed, as this is Asus's last shot. And I really love just everything about this laptop. Just everything screams awesome. But if its going to run hot and throttle. I'm going msi route. I know that'll run hot and throttle, but at least ill get 4800 and 880m for the same issues.

Havent noticed any turbo fan. I know cpu fan seems to ramp up pretty quick but only when you jump to full cpu load. And that maxes around 4500rpm, never seen anything higher, typical idle is 2200 rpm, and average rpm around 3000. Gpu fan I barely ever hear or even feel, but I do know that the gpu fan is larger than the cpu fan, which I don't get since gpu fan rarely runs and cpu fans always on. But either way, ive never had a problem gpu side of things, gpu still sitting at 90c after an hour and a half of 3200mhz cpu, no dips just a constant 100%. Oh its been so long.
Ill keep checking actual rendering in between so many groups of updates I do, and lets hope that this thing stays good.

dblkk, answered my own question while looking for a snippet to show you where to turn on the GPU fan "Turbo", it's not "Turbo", it's "Run GPU Fan on Full Speed", and is toggled from the Asus GPU Tweak Tool for Laptops.

The only screen shot I have is from when I tried that version on my G750JH, which of course isn't supported, but it shows the switch/toggle for the "Run GPU Fan on Full Speed"



I don't know if it will affect CPU temps too, but it might be worth a try to see what effect it has on your overall temps for rendering.

[dblkk]

Oh yes, I have seen and tried it once to see what exactly it was. And yes, it turns that bigger gpu fan on max. Not sure what rpm it was, but boy was that sucker loud. Havent tried it while rendering as typically core usage is very low and only gpu memory gets used. But next run ill try it out.

N/m, I was still rendering so I tried it out. I was bouncing between 88c and 92c, with gpu fan max im bounching between 86c and 88c. So apparently it does help out a little.

the cpu fan stays at current speed, gpu fan speed is 25500, which would explain why so loud. gpu temp same at 40-42c.

dblkk, that's great news, I was hoping the Max GPU fan would increase the cool airflow into the laptop, which the CPU fan can then "draft" off of, and that is a good improvement off the top temp for the CPU, about 4C 🙂

If you can take the noise, perhaps on long rendering jobs it will be worth it. I don't think the fan is really running at 25.5k, but I haven't heard it - maybe it is.

Interesting that maxing the GPU fan didn't drop the GPU temps... perhaps the load on the GPU isn't high enough when... rendering?? Wait, did you check to make sure that the rendering is happening on the Nvidia GPU instead of the Intel GPU? Those Nvidia GPU temps are idle temps...

I wonder if its the paste jobs you had on your previous laptops. It seems there's a varying degree when it comes to temps and these laptops from one to another.

It reminds me of a time when I picked up a GTX295 back in the day and had 4 screws missing from the chassis out of the box. This caused the VRM's to run under load on one side of the card at 105c. That was a $530 purchase for a single graphics card and the QA was lacking. I ended up getting in contact with the manufacturer (eVGA) and they send me a whole set of new screws. But it goes to show that poor QA can lead to high temps on these heat sensitive electronics if everything is not seated correctly. I would repaste myself normally, but these G750's (and laptops in general) are no joke to take apart to that level where you can repaste.

While these notebooks are great performance for the dollar (I doubt you can find better), the QA does seem to slip at times. My sister recently picked up a refurbished Asus Ultrabook and the touchpad was as others have reported on some of the G750's here where the touchpad was so very slightly off center, this caused a small 2mm or so gap on one side which is easily seen on a laptop that is all aluminum in color on everything and that small gap is black. Its not enough to make her return it, but a noticeable eyesore none the less.

If Asus would go just that little extra mile to make sure QA is there, issues like this and others may be reduced. 10 degree's is a pretty big difference when you're running a product at 80-90% thermal capacity.

Thanks for all the info DBLKK, here's to hoping your current G750 holds up temp wise!

Yes QA should be better, especially with a $2000 laptop. But I think my main thing is, and why I'm having so many problems, that I'm rendering a lot with the laptop. Benchmarks will put a synthetic 100% max cpu load, but I'm actually putting a 100% pure workload on cpu. Yes mine does run a little warmer than it should otherwise, but I'm working this thing hard. I feel that way more users have the same issue as I have, they just don't know it as they are probably just gaming on it. If that makes any sense.

I'm sure the misaligned/improper amount/bad mixture of thermal paste is to blame. And although it could eaily just be a hit or miss, I think its probably the machine itself not lined up. Laptop still works just fine, games fine, runs programs fine, and never throttles. But when you use the most demanding thing (video editing/3d rendering), that's where that just little bit of umph comes into play.

And as for Asus being the great performance per dollar, that's got to go to the MSI GT70 dominator pro. For similar priced asus, youd get an msi with 4800 i7 and next step up graphics. But for best overall performance/quality gaming laptop, yes that's asus hands down. Honestly I think its just the best. The msi is a better value, and the alienware might have an edge on quality, but for performance/cooling/quality/looks/feel, Asus just hands down.

Actually, if you truly wanted great performance per dollar, I'd look at some of the Sager/Clevo models. 😉 I was strongly leaning toward them, but all of the models with the Maxwell 860M were single heatpipe per CPU/GPU and single fan. >_<

Yes, gpu temps were idle temps. Which would easily explain the temperature. And yes the drafting/increased airflow was a nice call. I also tried running max cpu at 99% to disable turbo. I know it'll work and it'll help, but not what I expect to have to do on a $2000 machine known for its cooling ability. I'd expect that much from the single fan msi, but even then normal high temps on msi are both cpu/gpu at 90c. Which I doubt we will see 90c gpu on asus, but for a while there I would've been tickled pink to run 90c on cpu.

But yes, now its the long upgrading, installing, hardware transferring, software installing grueling process that comes with new laptops. Hopefully this time tomarrow ill have everything almost back to normal.

As for GPU speeds, it is yes noisier than the cpu running at 4500 rpm, but given gpu is larger fan and 25k is 6x faster than cpu, I doubt those are accurate speeds. But yes, very nice to know I have that option if need be.

dblkk, is the problem with running your rendering software on the Nvidia GPU an Optimus switching issue, or will it not run at all on an Nvidia GPU? Would it run on an Nvidia GPU on a JW/JX/JH or would it fail due to not having access to an Intel GPU - as it is disabled on those models?

I would think the performance improvement running on the Nvidia GPU over the Intel GPU would be worth pursuing.

The Sony site seems to think the 7xxm and 8xxm have CUDA support above Vegas 11:

https://developer.nvidia.com/cuda-gpus

There may be some tweaks you can use with Nvidia Inspector to force the Vegas app to use the Nvidia GPU? It really would be a nice comparison between the Intel and Nvidia GPU.

I wonder if there is a way for the CUDA processing to be accessible even when the Intel GPU is the primary processor for the app? I seem to recall, long ago, setting up both an ATI card and an Nvidia card on a desktop, and using the Nvidia CUDA processing for SETI@HOME while running through the ATI card as my primary video.

Interesting thread on keeping Nvidia speeds during rendering, might be a bit early, first you need to figure out how to force Vegas to use Nvidia:

Yes, both vegas and powerdirector my main used programs are easily set and I think globally set to performance/NVidia.

I had to force photoshop cs6 and pinnacle studio, but that's jut because they were globally set to NVidia.

I also set chrome to nvida and IE to stay intel. That way when on battery I know ill just use ie but if I want/need temps down ill run chrome

dblkk, ok 🙂

So you left the rendering on the Intel GPU/CPU to test the max temp loads?

You can also use prime95 for that... or are you finding the rendering is a more intense load than prine95? Thats good to know, I use prime95 for power supply / cooling load testing, if Vegas is a higher load, maybe I should start using that.

What is the performance X for using the G750 Nvidia GPU over the G750 Intel GPU for Vegas rendering?
