GeForce 8400M GS - Idle Temperatures

Hi everyone,

If you have a GeForce 8400M GS in your Vaio please take a moment to help us collect some information. This thread was inspired by @sinstoic's very useful thread in the Dell forum. It might be beneficial for us to do one of these for each of the G84M & G86M variants.

If you have a FZ go here instead. If you have a AR go here please.

After you vote please answer the following in a reply. Thank you!

1. What model Vaio?
2. What is your idle GPU temperature (in Centigrade)?
3. What software was used in measuring your GPU temperature?
4. What was the temperature in the room during measurement?
5. What video driver was used and where was it obtained? (If applicable please indicate if you've over/under clocked the GPU as well.)
6. What operating system was the temperature measured under? 32bit or 64bit?
7. Please indicate the power scheme in use when the temperature was measured. Was Powermizer enabled or disabled?
8. Where any modifications used to obtain the temperature? (e.g. Software Fan Control, Hardware Modification, External Cooler, etc...)
9. What has been the highest temperature you've seen on your card? What application/game was used when this was obtained?

 

1. VGN-SZ780NW
2. 68°C
3. GPU-Z and RivaTuner
4. 75°F (23.8°C)
5. 175.80. LaptopVideo2Go
6. Windows XP SP3 (32bit)
7. 'Always On' power scheme under 'Power Options'. Powermizer disabled
8. No modifications.
9. 84°C. Devil May Cry 4 Demo

 

1. SZ740
2. 64C (but i voted for the 65-70 cuz thats what its ususaly at)
3. GPU-Z
4. 80 on the thermostat (feels like it might be 75)
5. Bone stock clock
6. Vista 32 bit
7. Powermizer? whats that?
8. Vantec laptop cooler under the PC with fan on max!
9. 69C after 3dmark06

 

Powermizer (Nvidia link). I think it was also available in the 7xxx series (possibly earlier under a different marketing name). It decreases/increases the GPU's clockspeed dynamically when needed with the goal of conserving battery life.

I *think* there were issues with their SmartDimmer software and the brightness functions on Vaios.. There's a couple threads on it somewhere around here..

 

1. Sony Vaio SZ71Vn/X

2. 61°C /62°C / 63°C

3.TechPowerUp GPU-Z 0.25

4.Room Temp 20-21°C

5. Dribver Version nvlddmkm 7.15.11.0128 (ForceWare 101.28)/Vista (The one insatlled from the start)
No modification, I wouldn't know how to do it and wouldn't like to void my warranty either

6. Windows Vista Business 32 Bit

7. Power Sheme Vaio Optimized

8. No modifications

9. I wouldn't know, I've played some games on it but its been some time - and I hadn't had the software to measure the temperature nor the incline to do so.

 

1. Vaio SZ680

2. 59°C/60°C

3. GPU-Z .2.6

4. Room Temp: 22-23°C

5. Driver 7.15.11.0128

6. Vista Business 32-bit

7. Vaio Maximum Battery Scheme

8. No Mods

9. I don't really play any GPU intensive games, so never really monitored the temp.

8. No
9. I usually use the onboard Intel Graphics Graphics Media Accelerator X3100 and only switch to the Nvidia one when i game which is not often nowadays; but will monitor when i do and report back.

 

1. VGN-SZ94S
2. 48°C. 64°C After gaming (Downclocks to 275Mhz/301mhz)
3. Nvidia Control Panel(Classic)/GPU-Z/RivaTuner

5. 169.04 LaptopVideo2Go. (During games @550Mhz/700Mhz)
6. Windows XP SP3 JA (32bit)
7. Maximum Performance On (Except CPU). Powermizer enabled.
8. Laptop Cooling Stand (Porcelain Plate). Battery Removed.
9. 83°C. Colin McRae DiRT

Hmm i think there is cause for concern for people who voted 85°C+ as their idle temperature.

 

Not necessarily. People who voted 85+ as their idle should also report their CPU temps as well. They could have a dust-clogged fan, and a higher than normal CPU temp would indicate that...

 

It's a setting in the Nvidia Control Panel. Should look similar to this:

Faster drive would also increase the overall case temperature a little as well. I wonder what OS they were using.
