What is this bug? Trying to figure out what it is altohuhg it does not seem to affect me. Is it definatly a bug? Want to try and help to get this fixed, but I don't know what it is and it doesn't affect me (I don't think?)

Cheers.

Well it doesn't effect me neither, but my setup is watercooled.
I've no fanspeed to be controlled via the graphicsboard. (not anymore)

Is cooling fan speed lowered by the drivers and does this cause the "temperature bug"?
Or is there something else going on?

Hmm, I think someone actually proved that temperatures do increase with newer driversets.. but not as much as the driver temperaturesetting reports! I'd say it can actually vary from 5-10*c.. so I'd say it's definatly a bug :)

Mine's also watercooled, but the temperature that the drivers temperaturesettings report jumps from 50c to 55c when I install new drivers, but decreases by the same amount when I first oc' and then use default speeds!

Yes, but didn't I hear that it was actually a bug being fixed? That temps were being reported lower than they really where?

I have an nvsilencer5 and I don't think its fan speed is controlled either, perhaps the default fan speeds are now lower to keep the thing quiet when it isn't needed - after all 3dgames these days have 3dsound so you won't hear the fan if all is well..

I also have an ultra, whereas most people I have seen mentioning this bug seem to have the GT?

The temperature rise has absolutely nothing to do with fan speed. It happens on mine and my NV5 is plugged directly into the PSU.

Never had this prob on my Ultra or my bros GT(both BFG's). Temps with all drivers are within 1c degrees which is normal imho. Hope they figure this out soon as it definitely seems to affect a lot of people

Has anyone done any tests or have any more information??
Gonna play with rebellion commando (or something) tonight so may not be about depending on how good or bad it is :p

Here's my take on the temp bug....

I have a BFG 6800GT OC AGP.

With the 71.20 or earlier drivers my temp readings are:

54-58 - idle
70-85 - load (3d)

With any later drivers temps are:

64-68 - idle
70-85 - load (3d)

My stock clocks are 370/370.

If I overclock the 2d to 402 the 2d temp gradually drops back to 54-58 range with the newer drivers.

I don't believe it is a reporting error because if it was it would seem thet the temp should drop right away not gradually. Also why are the 3d temps not affected if it is reading wrong???

My guess is that either the fan spinning slightly slower in 2d mode or that there is an actual 10c increase for some strange reason.

I talked with a tech support person at BFG and they said that as long as the temp of the CPU stays below 90c that the chip is safe.

It would be really nice to get something official from Nvidia on this issue.

I don't have the problem either. I have a XFX 6800 Ultra that is a very early model. My 2d and 3d core and memory clocks have always been the same. 425/1100- that may be why I have not had any issues.

I noticed the temp difference when I was going back and forth between the 71.24 and 67.44 drivers. The main BFG 6800 Ultra in my A8N-SLi was reporting 39 Celcius with the 67.66 drivers and 51 Celcius with the 71.24s. Any drivers dated after the 71.24s that I have tried have exhibited the higher temps.

Just drop your 2d clock down below 400 with 71.84 installed.
You'll notice it go up about 10c then drop gradually back when you raise the clock back over 400.

6800GT's see it more because default is 350-370, and ultras seeing it isn't as common because the 2d clock is higher. Read through http://www.nvnews.net/vbulletin/showthread.php?t=46741 for more info. Most of what's known and tested is covered.

A couple more with info.

Personal experience:
Fan speed doesn't matter. From 40% speed to 100% I only see a 2c difference idle. (Those who have fans not controlled by the video card still see the increase) External sensors show the same increase and it drops gradually when overclocked to 401 or higher, not instantly. So from my own testing I can say it's not fan speed or a misread by the cards sensor. It is actually running hotter.

Definitely not fan speed. It does the same thing on my Gigabyte vanilla which is passively cooled. OC from stock of 325 to 350 and it dropped by 10 degrees gradually.

Mine is a XFX 6800 Ultra (AGP), board ID 4008, default 425/1200.

Maybe it's an issue with other, newer board revisions, those have other clock settings in the card's bios (setting RAM to 600Mhz is translated into 598Mhz), board ID 4033 and newer. Maybe they have different temp sensors too...

And with people flashing their cards like crazy all ignoring the board ids..it could be more important...

If you check out the posts by macatak and others with ultras in the links in this thread you'll see that ultras are affected as well. There's even a couple 5950's I've heard of. But as I said in the earlier post, if your stock speed is 425 (higher than 400) you won't see it unless you underclock.

Me always affected with those Beta drivers :D

Same here except mine is a PNY 6800U that I modified (the bios, that is) to have default 2d/3d of 425/1100.

@ EP...Yes, cards that are affected have a default 2d core speed of 400MHz or less, my default 2D core speed is 400MHz and the drivers that raise the temps are 71.40. 71.50, 71.80, 71.81, 71.83, 71.84, 71.90 and 75.90.....70.41, 70.78, 70.90, 71.20, 71.21, 71.22, 71.25 don't raise the temps. Overclocking my 2D speed to 401MHz will cause the temps to drop from aroud 68*C to 57*C and this drop can be verified by measuring the air temp coming out of the cooling fan housing.

*edit* i'm sure you could reproduce these results on your Ultra by using RT and setting your 2D clock speed to 400MHz or below, tick the " apply these settings at windows startup" box, restart your comp and check temps, if the temps are higher then change the 2D speed to higher than 400 and click 'Test' and watch the temps drop.

;( well. i checked out with my thermal gun.....temps are REEAAALLLYYY low compared to the what the driver is indicating on screen.

69c idle ("bug:) / 34c ambient (thermal gun reading)

its cold here in FL... :D

I don't think ultras are affected.

I have two PCI-e BFG Ultras that are showing the temp differences.
