Which driver shows the right temperature Dell XPS M 1330, Nvidia 8400 GS

Which driver shows right tempature?
When I use Nvidia 156.69. A BIOS 12. Idle 49-52 C

When I use Nvidia 175.97. A BIOS 12. Idle 62-63 C

Nvidia stability tes 10 minutes, 35 pass completed.
Highest 68 C, 49 min, value 56
This test was with 156.69.

It's almost certainly 175.97, given the mean temperatures reported in the forums. 49 - 52C is just too low; the M1330's stock cooling system simply won't provide those kinds of low temperatures.

 

Mine is also 175.97 and idles at 61-63C. The earlier driver 174.xx also showed a similar range. So I think 175.97 can be trusted.

 

Ok, strange...my computer feel wery cool. I cant feel any heat on the top or bottom when i am just surfing the web. My HP 9050 with ATI 256, feels hotter on the palmrest and the bottom.

 

Stigvig, mine too - and I noticed the same disparity between the 156.69 driver (which came preinstalled on my 1330), and the 175.97 driver (which I now use.)

The danger, perhaps with the 156.69 driver is that if it is giving a false reading (which is likely), then the fans will not kick in at the right time, to prevent the GPU from going over the normal-usage max. temperature.

 

167.45 drivers for me and since I can acknowledge that the thermal issues of the M1330 couldn't possibly allow me to have that low of CPU and GPU temperatures in comparison to the accurate drivers, switching to the 175.97 drivers and all the other drivers with the accurate numbers only make my system run hot. Within five minutes of installation, the palm rests become hot, the keyboard is hot and the back of the notebook is hot and that's on a zalman NC1000 cooler. The minute I go back to my good old trusty 167.45 driver, everything cools down. I've tried every new Dell release driver since it's came out and with the same results. Maybe the numbers are inaccurate with certain drivers, but I refuse to believe its the placebo effect and what driver I continue to use (albeit an older driver and from laptopvideo2go) doesn't make my system run cooler.

As for for the fans kicking in or not kicking it at the right time; after this whole fiasco with Dell and the GPU going in to meltdown, I've lost a whole lot of faith with their ability to pinpoint anything or reassure me that whatever they are doing is contributing to the well being of my system. I'd rather monitor the numbers manually and as for the fans coming on at the correct temperatures, there is nothing giving me any sign that the fans aren't doing their job at the correct time with whatever stressful activity I'm doing on the M1330........and as I've said before what is that correct time for the fans to kick on, because up to this point the fans could run at high speed 24 hours a day, it won't change the fact that we've got a poorly thermally designed system with a questionable GPU from Nvidia and all the tweaking in the world with the bios and Nvidia drivers won't mask the fact that Dell has and will continue to have a problem on it hands until it redesigns the thermal cooling assembly.

 

The best way to measure the temperature is through a digital thermometer.

 

Hi, I have the 7.15.11.5669 drivers. What does that correspond to in your driver terminology? Also, where can I find the nvidia monitor view program; I looked in the nvidia control program but found no temperature monitoring program? Much thanks!

 

Your driver is 156.69.

You can do a search for HWMonitor in Google. It's a free program which will display your GPU's temp, as well as the temp of your CPU. It's free.

 

yasdaz, I dont remember, but i think i found Nvidia Monitor Wiew on Nvidias homepage. I really can feel differents in temperature with 156, 69 it it much cooler on top o bottom....its not a placebo effect...

 

It is obviously a placebo effect, however.

If you update to the 175 driver, does the temperature in your monitoring programme (I would actually use two simultaneously) instantly change, or does it climb? Equally, if you revert back to the 156 driver, does it instantly reduce, or does it gradually come back down?

If the answer to those questions is instantly (as I suspect it is), then clearly one of those drivers is giving an incorrect reading, and the other is correcting it. Your GPU would not heat up or cool down instantly by 10C simply because you updated the driver.

QED.

 

tabten5, You hawe right!
I have checked the tempature again....and its now 60 C-61 C idle.
And the palmrest feels cool. So it is a placemo effect.

This is 11 C ower the tempature on my HP 9050, with 20,1 screen and ATI 256 mb GC on idle.

 

My apologies, Stigvig, I am not following you. You have the 156 drivers and it feels cooler but you upgraded to 175 and it felt hotter? However, you checked your temperature and it rose with the 175 but that was the correct temperature all along because the 175 reports the temperature correctly? Sorry if that was convoluted! This whole thing I am finding convoluted. Okay,so I have the 156 drivers that incorrectly report the temperature as lower than it should be. If I upgrade to the 175, it will report the correct temperature? I am running 64 bit so I can't get the 175 drivers from Dell (they are only having the 32 bit drivers for 175). I can go to the video laptop2go site (sorry, forgot it's exact name right now) and download them I guess. However, should I download the 175 or should I get a more recent driver since I am going there anyway? Thanks for listening all of you !
