GL703GS cpu undervolt?

[CLXX]

Hello,

I just bought a GL703GS yesterday, found it for a really good price that was the main reason i got it. after a few hours of gaming yesterday, i saw the cpu went up to 98 degrees. i think the fans were set on balanced and not overboost, but still seems a bit hot imho, the gpu did not go higher than 80. now since i have no clue about undervolting and this kind of stuff, my question is:

Can i undervolt the cpu and keep it like that from now on without any issues? I would like to get the cpu closer to 90 degrees under full load.

Laptop specs are: I7 8750H//GTX1070//16GB RAM//512SSD//1TBHDD//1080P GSYNC@144HZ.

 

Thank you in advance.

You can undervolt the CPU. Repasting helps more though, Asus isn't known for good factory thermal paste.

well atm i cant change the paste, due to various reasons, so undervolting will have to do. which software should i use to stress test after the undervolt and for how long?

That seems high, I havent seen my GPU go over 81C and I don't think the CPU has gone over 76C at 3.9Ghz all-cores.  Although I haven't stress tested under 100% load but I DID play Assassins Creed Odyssey.

 

I HAVE noticed the feet they used are crap though, drops 5C off temps by raising the base of the laptop and you can audibly hear the fans stop whining from struggling to pull air through a restricted space.  I have some taller feet on order off eBay.

Intel extreme tuning utility is what you'll want.

But as already mentioned, you'll get better results with a repaste. I've done it and can verify its better. If you need help under volting, feel free to ask.

it was on a cooling pad, which is thicker than the actual laptop itself, from what i remember the fans where on balanced and not on overboost, i will retest that later today. for testing the final results i will use prime95 for at least 6 hours.

for the 8750H should i start with 0.050v first?and then go lower by 0.010 or 0.005?

Have you tried without the cooling pad and that its blowing in the right direction onto the laptop base?  I don't trust them personally as you can't be sure they are pushing air at the same rate or to the right places as the laptops fans and you don't want them fighting each other.  I believe raising the laptop off the table should work just as well as these fans shift a LOT of air on their own if given the chance.  I've experienced less airflow from public hand dryers.

 

I don't bother with overboost as it seems to make very little difference to the performance or temperatures at the cost of being insanely loud.

 

I'm actually really impressed at how many games run perfectly fine at Silent despite it clocking the GPU down to 1.2Ghz.  Its quite the beast of a laptop.

 

This laptop has also totally spoilt me on frame rate.  I was happy with 4K 60fps on my desktop and now had to drop to 1080p 120fps as it feels so much more better.  I had totally forgotten the days of CRTs where the higher refresh rate makes the OS feel more responsive because if the shorter delay latency.

That model runs hot. Need undervolt+repaste

tbh i mostly use it in bed on my lap, and i will try it without the cooling pad(maybe get a new one), noise i dont mind since i use headphones while gaming, i just want the cpu temp to go down, it is way to high imho.

and as u said alex, it is a beast :D, the screen is fantastic, and coming from my "old" 6700HQ and gtx960m" it feels out of this world :D.

thank you guys for the help, asap i will start the testing and keep you updated.

Mine is just the 120Hz screen which I believe is supposed to be slightly worse picture quality than the 144Hz model, but honestly it looks great to me.

 

In bed could be tricky if you are blocking the fans, I got a laptop cushion and the only problem I found is as I described, they didn't really use tall enough feet for optimal airflow but I haven't experienced any performance issues.  It mostly seems to impact the GPU rather than the CPU.

 

I tried undervolting with Throttlestop with -140mV but I get inconsistent results, I believe you have to fiddle with some drivers to prevent ROG Gaming Center for overriding it.

 

Prime95 is a pointless test IMO.  My desktop 8600k @ 4.8Ghz thermal throttles under Prime95 (ITX Case issues), but in real-world use it never ever does.

ok something is not right, i did undervolt .150v as you can see from the SS, after more than 1h of gaming, temps are the same....should i go even lower? prior to the gaming sesion, i did an intel burn test for 10 runs and it was perfect. gonna try and go way lower see what's gonna happen.

im gonna try again with ThrottleStop, and go as low as possible, will post results.

[CLXX]

so after further testing i think ive done it, ive undervolted with ThrottleStop, now i am -120v and after 1h37minutes these are the result, on balanced fans. maybe i did smth wrong with xtu and the setting didnt save or smth. the gpu was at 76 degrees. untill ill change the paste i am happy, maybe when i will have more time will try to get it as low as possible.

[Alex Atkin UK]

I don't think it works reliably without removing certain Intel drivers, as ROG Gaming Center overrides Throttlestop.

 

My first run I got my temps down to 79C max, when I exited Throttlestop back to 94C, launched Throttlestop again and still 94C.

You can undervolt GPU too

 

Monitor clock speeds too not just temps

to be honest i dont want to undervolt the GPU, since im ok with the temps, has not gone higher than 80, usually is between 70-80, sometimes it goes into "no load limit": gpu clock: 1800mhz, memory 4000mhz: cpu clock in games 3.9mhz, and in test it stabilizes at 3.3mhz on all cores.
