G1s/G2s owners listen up.

Alright, so there is this stuttering a huge bunch of G1s/G2s owners are suffering of- You know that stutter that occurs at temperatures of 96°C+ and that can be avoided by doing the sleep-mode workaround and it looks like this:
http://www.youtube.com/watch?v=nMfSrLNXtQo

So now to the matter:
No, I can't tell you anything new. I've just grown tired of this and since I haven't tried yet, I want to give it a shot contacting the local Asus support.
What I would like you guys/girls to do is take this poll so I could at least point at some numbers when the standard babble about wrong drivers and stuff comes up. The way I see it, there are too many people suffering from this to blame it just on wrong drivers and everyone who followed all the other threads closely will know that it is much more than just a driver issue so I want to produce a little steam on Asus with your aid.

Please take the poll and tell whether you are using a G1s/G2s with an 8600M GT graphics card inside and whether you have that stuttering or not. Also I'd like you to post your GPU idle and load temperatures.
Thanks guys!

One more thing: This is NOT exclusively about the GoW or UT2004 stuttering so please, people, don't tell me anything about modded .ini files and please don't tell me about undervolting and powermizer either. I'm tired of this discussion always losing the point after two pages because of some dude coming in and claiming to have solved a serious hardware problem with engine tweakng.

So again, thanks in advance. I'll be happy to tell you what the support said.

 

G1S Butter smooth since august 07 .

 

Thanks for your response, freerider.

To you and anyone else- would you mind posting your GPU idle and load temps?

I'm hoping to discover a pattern that indicates all of the stuttering machines' cooling solutions be faulty.

 

Not really idle temp, but torrent and multi-firefox is
GPU=76°C
CPU=60°C
HD=48°C

at an ambiant temps of approximatively 30°C

 

Stutter after about 95°C. G1S.

After putting laptop into sleep and bringing it back... no stutter.

 

I've read many people with G1 series with this issue. But I have no heard of anyone with a newer G2 series with this problem.

 

@those who did the poll but did not comment:
Please people, I don't want to bug anyone but if you took this poll and voted that you don't have any stuttering please post your temps or at least some kind of comment about you not having any tempsensors running.

It would really aid my point in front of Asus support if it turned out that everyone not having the stutter does not have GPU temps above 80something so I hope you get the point and post your idle/load temperatures if you are not having the stuttering. Thanks again.

 

Evening, i voted "G1S smooth" because i manage to keep my laptop cooled down. I have however tested and documented that the stuttering begins at 95c due to a throttle down. This happens in all the games i play. COD4, UT2004, Quake, Planetside, BattleField2. Absolutely all games stutters when it reaches 95c.

Some also say that the 8600 has problems with memory that it stores memory on both the card and in the physical memory. I don't know if thats a fact, because i haven't tested it, but it sounds plausible and would explain how come some people experience stuttering at lower temperatures.

So voted smooth, but the truth is thats only if you can keep it cool.

I get stuttering like hell when i reach 95c.

At first here you see the frames at 340 AVG and the temperature increasing steadily. At the top it was 344 and 95c.


On the second image here we see the temp when its reached 96/97c and that the AVG frames is starting to decline.


On the third image it is quite clear that it will continue to decline until it reaches lower temp levels.


And on this last image i have reset the AVG counter to show the real-time effect and not the avg from when the test started like the above shows.



discuss all G1S related material here on the G1S Resources thread. Post your results and knowledge, its updated frequently and all validated information is put on the front page / 1st post.

Idle: Low to mid 70s.
Gaming: Mid 90's, usually peaks at 96.

The thing with my laptop is that I don't get the stuttering until AFTER I put my computer into hibernation/sleep so I've just been avoiding those options till I can find out what the heck is wrong.

Hmm. Can't you use Synaptics to enable it?

Or else try reinstalling the driver. Maybe it forgets the setting (the default should be on)

 

Err, excuse me, guys...

First of all, thanks Irathi for the contribution. I read that other thread where you pointed the thing about throttling out. As for the touchpad thing- I'd still like to keep this focused if you don't mind.

You said you manage to keep your notebook cooler than 96°C. I assume you are speaking of an extern solution, aren't you?

 

Does this only affect G1S, G2S models, or also the newer G1Sn?

 

Yeh ive opened up all the lids and have it sat on top of a Zalman NC2000 notebook cooler. Gets my HDD down to 30-40c, idle cpu 40-, idle gpu 55.
Also ive replaced cooling paste on CPU and GPU. Oh and btw - look at the review for the M50, OMG EASY ACCESS FOR THE WIN!!! - replacing the GPU cooling paste was horror on the G1S!

EVILGASMS FTW§!

 

Yeah, thanks for your comment on your cooling solution. I assume I can count you on the stuttering side then, since your laptop could not manage to cool itself in a sufficient way which is the fact I was hoping to gather some proof about.

 

How serious is the stuttering issue? Can you please describe what happens?

It sounds like hardware throttling to me.

8600GT 256MB DDR3 (500/800/1400MHz)
The latest 3DMark06 last night:
1280x1024 (no AA), drivers 174.93:
5230 points!

Code:

      Idle:       Load:
GPU:   55         88-92
CPU:   50         86-88

No shuttering with 174.93, no external cooling, thermal compound - Arctic Cooling MX-2

Explanation of the shuttering I had before:
The picture (D3D) hangs for about 0.2-0.5 seconds, the same time a buzzing sound is repeated by the speakers. This occurs every 1-2 minutes

 

The stuttering this thread is about can be seen in the video linked in the first post. It feels like everything is slowing down for the split of a second and then continues behaving normally. This happens repeatedly every few seconds or even every second.

Here's the video again: http://www.youtube.com/watch?v=nMfSrLNXtQo

Anyway, thanks for your temp readings, Predator. Those really look the way they're supposed to. Also the GPU not reaching above 96°C explains why you don't seem to suffer of this.

Does this mean you applied extra cooling paste onto the GPU on your own?

 

not "extra" but cleaned the previous paste and replaced it with MX2

 

Alright. I'll let ASUS know

 

Yeah, that's what I really meant

What do you mean, do you have any special link to Asus you might want to tell us about?

 

I do have a special link . Let's just leave it at that.

 

Fine then, I hope it'll help us poor sinners a little

 

viperabyss have you come to save us all from our anguish?

Any updates?

 

I guess Asus will rush door-to-door and give away free G1S FIX CD's LOL By the time that happens, we already are gonna be driver developers and can do better motherboard driver by ourselves...

Sorry for the offtopic, I just couldn't keep it to myself LOL

 

Well if Asus won't perhaps you can

You would be a hero to all stutterers everywhere!

 

I do too stutter as well when my video card reaches 95 degrees.

Buying a zalman nc-1000 has reduced cpu,hd temperature by a significant amount and has helped tremendously with the stuttering but graphics card still reaches 96 degrees under heavy gaming (tf2 maxed out, no AA). I am currently using 175.12 drivers.

Idle GPU temperature is at 61, under load without the zalman cooler temp is 96 and stays that way with lots of stuttering but with cooler it varies from about 89-96 and stuttering is dramatically reduced.

 

Yeh i can vouch for that. I got the NC2000. Idle temp on gpu 55 and it never reaches 95. - tho i got all lids taken off and ive lost my warranty because ive replaced all cooling paste on CPU+GPU.

 

Edit: Note: Measurements taken with ambient temp = ~70F
GPU 61C @ idle - 91-94 @ Full load
CPU 59C @ idle - ~87 @ Full load

-No thermal modifications(yet), no cooler, just bone STOCK.
- No temperature related stuttering during "normal" use. (I'm lucky)
- I CAN induce the thermal stutter via overclocking

Finally a BIG thank you to gr33nf4c3 for your noble public service to us ASUS "G" series owners. It really is appreciated. :wink:

 

Sorry, this is not the way I wanted to come off. I just wanted to keep this focused since it seemed to me that the GoW/UT2004 is not directly G1s related but rather a real driver issue that can be and was addressed elsewhere.

The problem is that this is a big forum and virtually every single user can come in and distract people from what this thread was supposed to be about- I believe I've seen at least two stuttering threads die of this and as I already stated I just wanted to have that out of the way at first hand rather than complaining about it later- that's why the disclaimer was there.

Having that said- ANY possible solution towards the stuttering problem is highly appreciated and I think you do know that- just everything has its place. I saw you contributing to the discussion in a useful manner and it's a good thing to view all sides of the medal- Thumbs-up and rep to you!

 

I've relayed the information to ASUS's technical support, and they should reply me shortly (hopefully ).

In the mean time, you can try underclocking and undervolting your GPU to prevent from overheating. So far there's no fix for software induced stuttering.

EDIT: Unless your driver supports undervolting in OS, you will NOT be able to undervolt them at all. Sorry for the false information.

 

Thanks a lot, bud!

Underclocking would not really help the gaming performance, I guess

Undervolting again might actually help a little. Sadly no one could point me at an application that allows you to undervolt the GPU. Do you know something I don't?

 

You can either use ATI Tools or Riva Tuner. Personally I use the latter.

 

wait, you say you're under volting your GPU with rivatuner? how should that work?? As far as i know you can only adjust voltages via BIOS, or am I wrong?

 

It depends on whether your graphics card support over/undervolting. As far as I know, all 8800, and 38x0 GPUs support that.

You can only adjust CPU's voltage in BIOS.

 

Sounds nice. Mind you that the G1s runs on an 8600M GT. I seriously don't think you can undervolt it just like that. Also where would that option be located in RivaTuner if you don't mind telling me?

 

omg my iddle is 77C, 110 maximum load

 

At least the second part is incorrect. You can easily adjust CPU voltages with software such as RMClock, from Windows.

I have never heard of GPU undervolting on this forum, though. Just underclocking which can indeed be done with RivaTuner.

 

Apparently it needs to be supported by the driver, and unfortunately, majority of the cards do not support that .

I apologize for the false information.

 

I voted "G1S butter smooth" but actually I found out that when I reach 96c, it hinders performance. I do not suffer any lag like you but the number of fps goes down.

Eg: when playing C&C3, fps falls from 30 to 22 or something, which is quite annoying

 

Assumably same reason, different symptoms though.

Here's another thread that describes the problem to the point:
http://forum.notebookreview.com/showthread.php?t=245851

 

Why dont you guys put some as5 on your gpu cores??? Both sides. it'll run 75c tops without custom vents

 

Both sides??????

 

Also, it's not like the guys in here didn't know what they could do but rather that they don't want to risk voiding their guarantee by repairing a broken notebook on their own.

Imagine the hours on end at 110°C that a GPU with a broken cooler had to endure. Sure you can fix it but what happens if that chip decides to cease function due to unbearable heat exposure as of... let's say tomorrow? Then you're proper screwed because you fixed it yourself, voided your warranty and are stuck with a broken notebook.

 

<--- G2S Owner

My wife and I both have one, I've drilled vent holes over the fan to allow cool air to be pulled in and pushed out on my notebook. Luckily if my notebook tanks, i can just swap the panel with my wife's before sending it out.

Temps:
GPU Load: 86 (with the mod!)
CPU Load 75 (with the mod)

GPU Idle: 63
CPU Idle: 57

The mod really doesn't help too much when gaming. what it did give me is a much quiter PC when im doing non-intensive tasks such as e-mail, web, etc.

Before doing the vent holes my GPU was in the low 90s which is what prompted my modification. I feel it worth mentioning that i dust out the fins and fan every month too to help keep it efficient.

 

Temps:
Gpu Load 75 (with my mod!)
Cpu Load 65 (with my mod!)

Gpu Idle 54
Cpu Idle 50

No Stutter Running stock Nvidia Drivers

 

@IdontFreakinKNow, when you say AS5 both sides. What do you mean? I did not think you could get to the underside of the GPU.

 

Btw, just removing the plate above the CPU and the FAN gains me 10°C CPU below...CPU load with it is 85, CPU load without it is 75. Unfortunately it does no visible effect on GPU, but on theory it should be increasing the performance of the whole cooling system thus reducing the GPU temps too.

@IdontFreakinKNow, I'm also curios, what did you mean when said "both sides"?!

 

So, no news from Asus ?

 

True, but if I recall the G-series has one heatsink connecting both the gpu and cpu, and without direct open air access to pull heat directly from the gpu you're still having heat back-transfer from the cpu at load. Same reason why if you run WPrime, Orthos or something else that stresses just the cpu (with the covers in place), you're also likely to see a bump in gpu temps - it's just a piece of copper, after all, and heat movement is symmetrical to some extent although proportionately higher toward the cooler fins.
