Geforce 9500M GS, 80° idle, solutions ?

Hello,
my problem is in the title
I know it's a common issue so I'm gonna precise it a little bit.

1 - These 80°c are reached although Powermizer is activated. I tried to desactivate it and underclock the core at its minimum (110 Mhz !) via Rivatuner or Ntune. But it doesn't seem to change anything regarding to temperature.
So first question, do you think it's normal ?

2 - I undervolted my Core2duo with RMclock and that's pretty impressive (-15°c and + 30 min on battery).
So second question (even if I think I know the answer), is there a SOFT way to undervolt the gpu ?
Third question (if the previous answer is NO ), is there a soft like Nibitor which supports the 9500M GS bios ? Because with the version 4.4 I can't edit my bios (and risk my warranty ??).
Fourth question, I'd like to know if someone did an hard undervolt changing the bios of the gpu and which results did he (she) get (temperature...) to know if this method is worth the risk ?

Thanks for your answers
Sorry for my english

Best regards

 

that sucks, mine idles around 40-45 C (my room is around 25 C, temp outside is 30-35 C). if u dont have any other answers, u can try opening up. i suspect there is poor contact, try AS5 and maybe trying the copper mod.

 

That is most likely a loose or warped heatsink. You should send it in to be looked at or you should take the laptop apart and make sure that the heatsink is screwed on properly/tightly and that there is thermal paste in between the GPU and the heatsink.

By the way your English is not bad at all.

Mine's idleing at 66C right now. Yeah, you're right, we need to have MVKTech update their software to support our card, so we can flash some new fan thresholds on there. Please add some comments to their thread and provide them your VGA BIOS. I have asked them to add support on Nibitor and provided a few BIOSes I found online, but I'm going to give them my original as soon as I figure out how to run nvFlash from DOS on this x64 machine - I just haven't had the time yet. Also, you might want to ask your manufacturer about those temps - They're too high. What is it under load (e.g. Crysis)? Are you Overclocked? Did you know the 9500M GS is a 84 M Revision A2 chip - exactly the one that's been reported defective by HP and Dell? ASUS says mine's O.K. though, we'll have to wait and see...

 

**** how come everyone's is so high? im using HWmonitor, idling at 45-50 now after leaving my computer on all day and night in 25-30 deg weather! according to GPU-Z mine is G84M rev. A2... FW drivers 175.61, standard clocks.

 

If the warranty is not a problem you could do the following:
1- open your laptop and replace the heating pad between the GPU and the heatsink with artic silver 5

2- use nvFlash and Nibitor to change the voltage setting of your graphics
Use goolge that is a lot of tutorial on how to proceed.

Forget if the laptop is a bit old you have dust that reduce the efficency of the heatsink/cooling. Sp if dusted cleaning it should reduce the heat.

 

You're right mcurran, I've a G84M rev. A2 according to GPU-Z. So I gonna look for informations about it before mailing Acer. Hum something is strange, I noticed that GPU-Z says "Technology : 80 nm" but I thought these cores where 65nm instead of 8600Gt, am I wrong ?
And guys, because you have a similar configuration, I'd like to know how long can you stay on battery ? like when you are on the 6x multiplier (1000 Mhz) and a desktop utilisation. I have only 1h30 available on battery and I'm wondering how much does these problems with the gpu decrease my battery life.

Btw, thx for your answers !

 

naton, I bought my computer only last month... so forget about the dust ^^ and Nibitor is not yet able to read a 9500M GS bios.....
I do know that opening the laptop could cancel my warranty but do you think that flashing the bios could too ?

 

did you try installung the hotfix from dell or hp, which increases fan speed to keep everything running cool?

I wouldnt take your system apart, cause many forum members have graphics cards which rise up to 100C and higher during games.

I gonna try this, thanks for the tip. However, I wanted to find why this gpu is overheating because my aim was increasing my battery life. I think the only way is undervolting the gpu (that should reduce energy consumption) , so i have to wait nibitor to be updated...

EDIT : that dell or hp hotfix seems to be a updated bios for some nvidia gpu, I can't use this for another card in another computer (Acer).

 

If you want a good program to undervolt/underclock notebook hardware control or NHC has all of these functions.

I think you can use rivatuner to adjust the fan speeds. if not you may get lucky with speedfan. you can adjust all of the fans in your system that it displays.

Good Luck.

 

you can only use rivatuner on desktop based graphics cards, since laptop graphics cards do not have their own fan controller like desktop ones have. In a laptop, teh fan is controlled by a temperature reading from a onboard thermal probe, which tells the bios whether or not to turn the fan on.

I do not know if acer has a hotfix for this, but i would check their website to see if they do.

The only thing I can suggest is to shut off Windows Aero in vista, cause that will put a continuos load on your graphics card. Try running your system for an hour or so without aero, and see if the temperatures decrease. If they do, than that would be great, but if not, check out the cooling guide.
You may want to invest in a laptop cooler or some rubber grommets to lift the back of your laptop up off the surface, so that more air can circulate under the machine.

My 8600gt idles at around 80c after done gaming, but that is a given with my brand/model.

 

Email MVKTECH.NET or use their suggestions forum to pressure them to support this card. A few have already provided their VGA BIOSES. It's our only option (Flash new temp thresholds with Nibitor). It would be a big help if we all asked.

 

mcurran I have already provided my bios via Nibitor itself (it told me wheather I wanted to upload this unknown bios or not) so we have to wait and see to explore this option.
A little information there, I figured that I have different max temperatures with different nvidia drivers. So now with drivers down to 177.73 I'm idling at 72°C eventhough Powermizer seems to act identically.
K-tron, aero is already desactivated... no change !

 

I'm gonna do the copper mod on mine, because I have a feeling Nibitor isn't going to support this GPU. The G1S owners started complaining over a year ago, and they still are left with no options (8600M GT - Still no fan control or fan/gpu correlation whatsoever).
