Studdering at high temps

I have a Asus G1S-B2 and I'm having problems with some studdering/slowdown once the card hits about 95-96c. This is at least in Oblivion, the only game I'm really playing on it at the moment. I had to actually downclock the GPU in order to be able to play it.

Basically what it does is goes into slow motion for a second, then resumes normally for a second, then goes back to slomo repeatedly.

Is this some sort of GPU throttling done on purpose? If the temps don't exceed 95c I don't have this problem. I have a laptop cooler but it shouldn't be required to use the laptop on stock settings.

 

The slowdown is because your GPU has reached its thermal fail-safe, making it downclock automatically so you dont damage your hardware from overheating

 

What are your specs? Thats pretty hot, if your laptop is 15"+ then you should look into returning it or getting it replaced. If it's smaller then maybe it's normal for your model.

 

Flipfire is correct unfortunately for us, as the G1S series seems to have heat issues; most gpus dont touch 96C while ours can hit under moderate gaming. Ive tried pretty much every free way i can think of to keep my gpu cool (Undervolting, increasing airflow around the laptop, and keep a cool ambient room temp) and now im thinking ill have to buy a cooler as well because none of those seem to work.

 

definitely smells like downclocking :\ btw, what clocks are you running?

 

Use the sleep trick, it will get rid of the stuttering and allow the GPU to not downclock itself until a higher temp (which I haven't ever reached yet).

Just hit sleep, wait for the power thing to blink/fade and then awake it. This has worked for me as well as many other users with the famous 8600 stutter issue.

 

You beat me to it !

Yeah. I was frustrated with the same issue until I finally discovered the sleep trick. At first (because my laptop was new, I was in a state of disbelief that this was neccesary, but it's really only neccesary if you use LV2GO drivers, because with the driver on ASUS's website, the GPU will never reach this temp.

The G1S and a couple of models by other manufacturers run much hotter than all other 15.4'' laptops with 8600M GT.

After my initial disappointment wore off, and I began to relax, I really learnt to enjoy my G1S, and I now see the neccesity of the sleep trick as a "Characteristic" rather than a problem.

I'm relaxed about the whole sleep trick thing. When you post that your GPU temp tips the high 90's when gaming, many forum users will give you a few of these > , and tell you to send it away for repair. Thing is though, it isn't broken ! -It's normal for the G1S when running LV2GO drivers (do watch out though because there was one I tried (174.31), as did G1S NOODLE, which bumped up the temp to 104 when gaming (over 107 in G1S NOODLE's Case !) All others seem to peak at around 97.

Everyone tells us that our mid-high 90's temp is going to kill our machines in under 2 years, but the thing is, we MUST use LV2GO drivers if we want to play the latest games (e.g. Gears of War won't even play at all with the ASUS driver), and so we don't have any choice but to use LV2GO drivers, and the sleep trick if we want to use our "Gaming Series" machine for the purpose for which it was intended, i.e. GAME !!! - Of course the high temp must be detremental, but we'll just have to see how much !

As I mentioned earlier, this had me really mad when the machine was new, but because I love everything else about it (quirks included I'm not going to worry myself about this issue.

Right now, I'd still recommend a G1S to anyone, without hesitation. (but maybe you could ask me again in about 3 years )

 

I get the same problem with my msi 1039 because I notice a lot of slowdown when I play call of duty 4 where there is usually no lag at all. But as a MSI user over heating is second nature and I hate this laptop for it.

 

If you are overheating... usually any temp over 90C degrees is bad.

when was the last time that you cleaned out the fans and vents thoroughly...?

if never, then thats why.

1) remove battery
2) remove/unscrew the panels on the bottom of the notebook to get to fans and vents
3) use flashlight to look through vents for the dust
4) go outside, get some compressed air (cans or compressor @ 50 PSI) and give the vents a good airing out all directions (concentrating on the vents)
5) go get some Q-tips and swab the fan blades and the area around it
6) then go do a second airing with compressed air (all directions again focusing on the fans and vents) to push out the dust that was dislodged from the Q-tips

7*) Now go use the flashlight again and look through the vents (shine the flashlight from the fan, you look through the other end) for anymore dust clogs.

8) Then start up the notebook... and let the fans cycle up (use the Fan Toggle at max speed if your system has it) to push out any other dust that might have been stuck.

If all goes well you should be able to close up the notebook and...

you're done.

*repeat this step until its cleaned out.

Thats pretty much it.

Just make sure to do this every two-three months... it should take about 15-20min per cleaning if you want to be thorough.

Gaming notebooks are a new thing, you must realize that you have to take some extra care of them over typical use notebooks:

1) Battery: to maintain the longevity of any rechargeable battery
- you must NEVER overcharge it [especially for long durations of time] by keeping it plugged into AC
- when it reaches 100% you should unplug it and let it discharge to 5-15%, then plug it back to power
- OR you can just charge it to 50%+ and remove the battery and store in cool place.. not the fridge [remember to use it occasionally 3-4 time a year to charge and discharge it].

2.) Heat: to prevent a healthy notebook from overheating
- ALWAYS use the notebook on a clean, hard & flat surface
- RECOMMENDED to be used on a notebook cooler... namely the Zalman ZM-NC1000 or ZM-NC2000
- check your fans underneath occasionally (at least once a month or two) for any dust clogs [clean them out with Q-tips and air cans/compressors]
- ALWAYS monitor the temps (CPU, GPU, HDD, etc..) to watch for fluctuations, which would indicate overheating by dust usually
(for Clevo notebooks) use the Fan Toggle to switch all fans to Max Speed when gaming and such.

By doing these simple things, your entire system will easily last for more than 3 years.

 

@gophn

last time i opemed up my old notebook, i ended up with 5 extra screws lol. is there a way to do this without opening the notebook?

 

the trick about opening the notebook is to just open the panels that are easy to access first.

Most gaming notebooks have access to the fans by removing one or two panels.

... other notebooks with lots of screws will require a styrofoam panel... I am not kidding.
- when you remove a screw, jam it into the styrofoam
- organize the screws in the styrofoam by placing the screw sets in a particular area
- use a sharpie pen to circle and label the screw sets

Its just that simple to help prevent lost/missing screws or not know where which screws go where.

you can try to push the dust out of the vents by getting a good pressured air compressor (set @ ~ 50 PSI) or air cans
- air out the vents both directions, inward and outward
- then use a flashlight and shine it through the vents from the fans perspective
- look to see if you can see the light clearly through the exhaust side
- if its still clogged, repeat the compressed air cleaning.

 

This is why I like my turbo engine. It makes the fans go FAST.

 

Certain notebooks, like the Clevo gaming notebooks, have a cool Fan Toggle feature to switch all fans to max to help push more air through the system...

... but if the dust collects enough, its worthless if the vents are clogged.

So a thorough cleaning of the fan and vents once every two months is recommend for a gaming notebook.

 

His machine is a G1S - B2. It's either brand new, or fairly new. Once again - It's perfectly normal on these machines, from new, with stock clocks. It isn't broke, and doesn't need cleaning !

 

Just make sure the temps are stable by using a good notebook cooler.

And monitor the temps.... to prevent overheating.
