Possible solution for G1S 8600M GT Stuttering!

Hey guys,

As many of you know the 8600M GT stuttering bug which kicks in past 96C has been causing us pain for months now, with no solution in sight.

The only workarounds being available is keeping the GPU under 96C or using the "sleep fix".

Well I've had an unexpected development today, I did a fresh format of Vista + SP1.

When it came to installing the Intel Chipset INF update, I went to the Intel site and realised that they had removed them!?

So on a hunch I tried went ahead and skipped installing them...

To my suprise, I now longer have any stuttering past 96C!!!

*Edit* I forgot to add, frame rates are approximately what they were before, also I am using Forceware 174.74 with the original oem inf (nvam.inf).

Now this could just be a coinicidence, but I will have to do some further testing. Anyone else game to do a fresh format without the intel chipset drivers and help prove/disprove this theory?

Note: if your GPU goes past 110C this will probably not help, because that is the thermal throttling temp.

 

umm... 96 degrees? seriously?

thats really really hot. is that even a bug? maybe its stuttering because its running at 96 degrees...

 

Unfortunately that is the norm with a stock G1S without any cooling modifications.

 

4c more and you could boil water using the gpu core

 

Driver conflict on your system maybe?

 

cant you control the fan speeds in ntune? if you can set it to 100%, might be only for desktop gpu's though with a built in fan

 

So your gpu stopped stutterin, but it's still just as hot?

 

Well i have a friend that have a g1s with this problem... when the tems rise to 96 degrees it have a big drop in performance.


Thanks to post this, i goint to try


(i have tried too that the g1s have drops in performance when video ram is so hot... ( http://66.102.9.104/translate_c?hl=...icado-problema-de-perdida-de-rendimiento.html)

 

It's possible

No AFAIK you can't control the fan speeds on the G1S

Yes, approximately the same temps and fps but no stuttering!

Hopefully your results will be the same as mine!

 

mm i tried to unistall all the intel controllers and leave windows install it, but the 96 C problem still ocurr.

we will try to format the friend´s g1s and dont install intel infs

 

hey, i'm not an Asus user however mine laptop too do stutter at 96 degrees (8600M GT)

thus I'm curious to the follow up of this story, anyone?

 

@alliao: Have you tried to disable powermizer by changing the perf level in the registry as suggested in the following thread: http://forum.notebookreview.com/showthread.php?t=261929
Also have you tried the sleep/hibernate fix. Where by you boot as normal, put your notebook to sleep or hibernate, wake it up and then game.
Don't forget that stuttering can also be caused by the drivers being set to max performance in the nv control panel. Set them to default and give it a go. It dropped my temps by 5C and helps stop any stuttering on my notebook. At the moment I don't see any stuttering with either 175.19 or 177.35 drivers.

 

I'm new to the forums here so hello everyone!

I'm having the exact same problem with the stutters, just to make shure it's the same problema I have this link here
http://www.youtube.com/watch?v=nMfSrLNXtQo

My problem also some moments after the temperature has reached 96º (it doesn't go above it), but as I monitor the card frequencies I see that there's no throtling taking place...but the stutter is there

Have tried EVERY possible fix to no avail...

Are there any news on this topic?

Thank you

 

theres only 1 real fix for the G1s... get a new computer, seriously

 

I don't really think that is helpful to the poster, now is it?

I remember two possible fixes being mentioned (possibly on this very thread):
- disable nVidia powermizer
- put the computer to standby (sleep) and then resume

Note that if these fixes work, they will disable the throttling down but also put your GPU in the danger of overheating.

 

Thanks!

The thing with the powermizer is very weird. No matter what driver I use, I can't see it in Nvidia control panel but it actually throttles down my video card when I'm not using it. Ex. Desktop. When I'm gaming though, I've already monitored my videocard and altough it reaches 96ºC I don't see the clock and memory speeds being reduced...and the game just starts stuttering.

I'll try this sleep trick out anyway and post my results later...

 

Don't know if this will help, but I think it's likely a heat issue.

You should run RivaTuner Monitor and see if the core/memory clock speeds throttles down. If it does, then that means that the Nvidia BIOS is kicking in due to th thermal limits. I had this same issue with my C90S. You may want to clean out your notebook heatsink, however, this may also link to the Nvidia problem.

 

I think that is indeed what's happening with this notebook, it's throttling due to heat at around 96 degrees. So basically it's overheating. It's not due to the "nVidia fiasco" (that's not something that leads to large temperatures). I think that those fixes I mention, if they work, work by bypassing these thermal controls, and leave you open to overheating. So use them with caution.

tschiedel, there is also a registry setting to disable powermizer, I think. There is also a util called PowerMizerSwitch.

Thanks for all the help! Although it didn't solve my problem, it helped me better understand it.

Just to clarify, I do no own an ASUS G1S notebook, I do own an Acer Aspire 5920G instead, but the videocard and heat problems are the same. That's why I posted here.

So, here are my findings:

Disabling powermizer doesn't as I have already stated above. I monitor my videocard's clock with GPU-z and they never go down while playing, just on desktop. Anyway I disabled it just to make sure and it didn't help.

It is definitely a temperature problema though. If I managed to keep my videocard UNDER 95..96ºC, wich I do for some minutes before it heats up, I get NO stuttering whatsoever. The stuttering starts only about 1 or 2 minutes after the card has reached 96ºC.

I find it very strange that the card heats up to 96º and never go above it. That is also the temperature that everyone with this problema is reporting also. I find it hard that the card doesn't get hotter even after ours of playing as it reaches the 96ºC after only about 5 minutes of gaming. It may be a bug or it really doesn't go up......it doesn't matter though.

My last and only POSSIBLE fix for this is trying to use one of those laptop coolers to try and keep the temperature below those damm 96ºC OF DEATH.

I'll buy one next month and post here my findings..good or bad.

 

96 degrees is definitely not normal. If you have tried the solutions above, I would suggest contacting Acer on this issue.

 

I have one more thing to add. I've managed to keep my videocard cooler by lifting the rear from my notebook. Instead of 96º I get now 90º while playing and now I can play without stuttering

 

I'm afraid that it is normal. I also own an acer 5920 and i confirm the 96 degrees threshold....i have to use a cooler in order to keep the temperature lower (but not lower than 93-94 C)

 

Hey guys!
Long time since I've posted last, but I saw this thread and couldn't help but inform you guys of something if you don't already know.

Nvidia's mobile GPU solutions are almost all defective. Contact your reseller or manufacturer to see if you can get it replaced.

Do a google search.

I'm pretty sure it doesn't effect performance, but the problem was a matter of the GPUs lifespan and durability.

 

I don't think any manufactures are owning up to Nvidia's mistake right now. So I doubt you can actually make Asus or anyone else help you fix the heating issues.

 

No, it isn't normal. The fact that PowerMizer was disabled probably makes this situation worst. I don't think this is a software issue, and I don't think we can make any recommendations other than goin directly to your manufacturer and tell them about it.

If it's not an ASUS, why are you posting it as a G1S?

 

Yeah, 96 degrees temp it's clearly not normal. The proof of it is that the card is throttling to keep it from getting higher.

As to the nVidia fault, Shampoo, yeah, everyone has heard about it. It's not even clear how much of it is rumor and how much is truth, because nVidia aren't releasing full information. But even for those manufs that did list the faulty models (Dell, HP) they are not AFAIK replacing faulty cards from warranty unless the card dies first. So yeah... there's not much we can do about it.

 

Well if you guys aren't under warranty anymore, I think reapplying thermal paste to your video card. I put some new arctic silver 5 down and my idle temps get 60 at idle. Max temps when playing Company of heroes is 88 using HWmonitor. If you guys dont feel comfortable doing that, just use rivaturner to lower your clocks. I did this before i reapplied thermal paste and it never got to 90c. i think i used 350/500 instead of 475/700. This really didnt effect the performance but it drastically help the heat. I hope that helps some people. good luck

 

Yep, especially the second is an excellent suggestion if the games you play are not highly demanding.

 

LOL just played company of heroes for an hour. This is with new thermal paste and lowered clocks to 350/500. CPU max 75/77c GPU max 81c No lag game plays perfect.

 

I bought the thermal paste but I'm freaked about opening this thing up to apply it... any guides?

 

Everyone, be aware that reapplying thermal paste will void your warranty. ASUS warranty is one of the strong points of ASUS notebooks, so I'd think twice - thrice - before giving it up.

I know that jpham209 already said so, but I wanted to reemphasize again.

There should be a G1 disassembly guide linked from the Info Booth.

 

Just to re re re clarify, people having the problem shown in this video http://www.youtube.com/watch?v=nMfSrLNXtQo are not getting their videocard throttled when reaching 96º. Core, shader and memory speed stay at their highest values and the image starts stuttering.

 

Yeah this is true. Irathi proved it in one of the other threads, either the owner's lounge or the other big G1S thread (the name escapes me right now).

The thermal throttling range is set to 110C in the bios so it shouldn't throttle at 96C.

Either way using the method I posted earlier in this thread, or the sleep trick will make the notebook not stutter till 110C.

 

But then, is there any clear explanation on why the stutter happens?

 

No.

Only speculation.

 

gpu works almost exactly like a cpu. You know when an intel cpu starts to overheat, it will automatically down clock to dissipate the heat. the shutter occurs when the gpu gets down clock so low that it cant handle the game or whatever you're doing anymore and most of the time it freezes. I know because i used rivaturner to down clock my gpu 2d to the lowest it can go 85/80....lol. it would cause shuttering so i would have to restart my computer. Shuttering is an after effect of overheating.

Im not sure this is true but the logic seems right through my tests. good luck guys keeping your G1S cool.

 

Yes, that's the logic (that I was using as well) but from the 2 posts above mine, it would appear this is not the case.

Unless it is some kind of "internal" throttling that does not result in a modification of the memory/core/shader clock readouts.

Something like this (example is for CPUs):
http://paulsiu.wordpress.com/2007/06/23/does-on-demand-clock-modulation-odcm-conserve-battery/

RMClock supports this feature for the CPU. It is called "On Demand Clock Modulation (ODCM)" and it is independent of the clock at which the CPU is running. So its effects will not be seen in frequency changes of the CPU, but the effective speed of the CPU will be lower.
