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.

So your running idle 10c lower than me? I'm sure integrated graphics have a play in that, wouldn't think it would be 10c, but honestly not to concerned/nor surprised with that. As you cpu idle is really only running background programs which is very minimal. Same goes for mine but its also pushing my display.


*Edit*
After restarting pc, and then forgetting about it and checking temps like 20 min after reset, idle are 43-45c on THRM and about 40-43c on core #0-3 and package.

Cool, literally 🙂

It looks like there are 2 steps of idle temp on the Optimus G750's, the normal idle where the Intel GPU is keeping the temps up during normal Windows use, and the low idle where even the Intel GPU has shutdown to preserve energy, and the temps drop to "CPU/GPU idle".

Here is the result from running Furmark 15 minutes 1080p burnin - along with CPU temps.

😮 makes for happy camper

People can argue that you shouldn't have to go through more than one and no more than two ever to get a good laptop. And while I agree, the Asus is just so damn good that its just to worth it to get a good one. And even with the thermal problems I had, it's still a better laptop than the MSI which at best would've been just as hot.

Decided today for heck of it ill try temps under stress. So ran intel extreme tuning and ran stress test. temps were around 95c average. So I tried to drop voltages, just a few notches down, and same thing. This is only a 5 min test, I ran 3 times and reach time averages 93-95, gets up to 97c. What the heck is going on here? Not yelling at you, just very confused.

Earlier I played a 'few' matches of titan fall. I have msi rival stats synced with my hwinfo to display cpu %, cpu temps, gpu%, gpu temps, and fps. I was getting high 80c while gaming on cpu, cpu was around 78-80c. The gpu is normal, but don't think gaming at 30%cpu should yield almost 90c.?

not happy in the least. Plus today was huge storm day, so inside temps should've been easily lower 60s at worst. Not a happy camper at all.

Thoughts suggestions? anything. This is 3 jm and 2 js models now, in which I feel that thermal throttling is not something I should have to put up with in a $1800 laptop

dblkk, what were the values for the voltage offset you tried? HomieOC did about -90mV on his, and his CPU temps dropped 10c, so give that a try 🙂

HomieOC, have you settled on a stable CPU/cache voltage offset yet? Are you still using -90mV, more or less? Can you please put together a nice post with directions / images for the new JM/JS/JZ users?

I was able to get -125mV on my JW, -75mV on my JX, and now I am stable at -50mV on my JH.

In November last year, initially my JH was only stable at -20mV, so it took some "burn-in" time to a good negative voltage offset on the JH. Gradually I increased the negative offset by -5mV every couple of months, and now it works at -50mV... better cooling the lower the voltage offset.

I tried twice lowering voltage. not exactly sure which ones as I'm not looking at it (I'm on my surface pro in bed now). but I lowered two setting 4 minus clicks. reran stress with no difference. I tried 4 more negative clicks, system unstable, shutdown/restart. so far not to good for undervaluing seems to really like those stock volts. As I'm not willing to give up performance I will not be underclocking or disabling turbo. Not spending this much to have to slow it down. I'll go mid before I do that. But I haven't given up yet, plus have a few more weeks before I have to send first one back, so either tommarrow or Wednesday ill be playing around some more and see if I can't get these volts or temp down. If anything ill just day f it and repaste.

dbblk, the underclocking/no-Turbo isn't recommended for normal operation, but it is good to know to get more juice out of your battery - plus it's nice to know how to drop the heat should you be stuck operating in a harsh environment.

The clicks are small, and 4 isn't very much - are you maybe clicking on the CPU Voltage setting - which you want to leave at Default?

The Dynamic Voltage Offset and Processor Cache Voltage Offset are the ones to drop. Click on the setting, get the pop up menu, mouse to the right edge and a scroll bar comes visible, click the Up arrow till you get to -50.xxxx mV on both settings, and Apply, then Save as a Profile name like nooc -50mV, so you can load it and other Profiles as you need them.

If you re-paste you might not get an ok on the return or refund... if you are prepared to keep it or sell it afterwards, then go for it 🙂

But, I am not so sure a re-paste will do more than the -50mV voltage offsets, of course combining both will be awesome.

It is also possible that there is nothing really wrong with the paste, it is just how the new Intel CPU/GPU runs with more of the Core Circuits - video section and rendering section powered up is going to raise the heat baseline.

It would be nice to know...

Lowering volts got me that temperature... My room is also very cool right now too.

If i put fan to max it idles around 33 c lol

That's a nice temp for -50mV voltage offset on CPU/cache 🙂
