Well you are running 2 video cards. It's a known issue with these beta cards when it comes to 2 running video cards even if you're not running SLi but you are still linked to two cards.

work great for me

These are looking real good...more testing...

Strange, but yesterday I tried this out on my second gaming machine. I decided to slide the 470 into this machine for some testing with BC2. Specs for this machine are
 
Gigabyte EP45-UD3P rev 1.1
Core 2 Q9550 clocked to 3.6/Ghz
8/gb RAM PC2-6400
EVGA SC GTX470 (stock clocking)
Windows 7 Home Premium 64/bit
 
After sticking that card in this machine, I decided to perform a complete clean install of the latest 260 driver. All went well, seemed fine. Jumped in game, and noticed a 10/15 fps rate. Came out of game, tried to figure out what was going on. Card clocked up to stock speeds when tested, as did the CPU. So I ran a 3dMarkVantage. My score is normally around P20400+, only managed a P7xxx. My graphics score was normal and in the low 17xxx numbers, but my CPU score was maybe a third of the normal CPU Vantage score.
 
Re-installed the driver with no change. So I wiped it clean, installed the last 258 driver, tested again and all was fine. Game played well. I installed the 260 driver over the last, the game improved and I was back to my 20xxx Vantage score. So, I tried it again. Clean install of the 260 driver with the same poor results. Re-installed the last official driver, then installed the 260 driver over it. Everything was back to normal once again. Obviously the clean install was missing something for the GPUs relation with the CPU.
 
Now, I removed the 470 and stuck it back in my primary gaming machine. I re-installed the GTX 285 card back in this machine, performed a complete clean install of the 260 driver, and it functioned properly. I did not note the same issue with the 285 card in relation to the 470. Sounds stupid, but that was my experience yesterday. Not sure why, just thought I'd note this.
 

Alright Anyone having the fan issue like I am. I can confirm that this is a Driver issue. 

Since I never store that much on my gaming computer I decided to a complete reinstall to see if the MSI AB and EVGA Precision and every other Over clocking tool Fan Adjustment problem would go away. 

It didn't.

I tried when there was hardly anything else on my computer. I tried to uninstall other drivers to see if another driver in conjunction with these drivers were the cause of the problem. Well to make a really long story short... I have been building computers for years.... and tried everything I know how to do. Nothing got rid of this issue. So I am convinced these drivers are the problem!

Just to recap what the problem is..... that when you try to set your fan speed manually in MSI AB/ EGA Precision or any other overclocking tool.... that program will show the wrong speed. Even though it has been set to the speed you need it to be.

Also if then you exit from that program and then try to re-enter the program later.  The fan will go back to default as soon as you open the program.

The bug also seems to cause the fan speed not to stay at the place you set it if you adjust any other setting in an over clocking program tool. For example you have the fan set to 80% and then you try to set your clocks to 800 Mhz core, once you press "Apply" The Fan will drop back to it's default setting. 
You can then re set your fan speed and press "Apply" Again and it will stay at that speed (Minus the fact that it will show the wrong speed) 

But this problem is still annoying none the less!

Again any ideas would be helpful? I am baffled! Sorry for the long post but I just wanted to make it clear to people having the same issue or see if any one is having the same issue?

I did a rollback as well. I had some stuttering problem while watching HD movies on my TV. Did the rollback and no problems anymore. This and the core clock not downclocking (staying at 405mhz) with only one monitor.

humm i seem to have lost my surround vision and SLI capabilities with this driver...

@20mmrain: I had that also with 258.96 and the older AB (now using 2.0.0), there it jumps like crazy. But that's why i never use the manually control of fan, only my profile. There it works good, till now!

I overclocked my GTX460 SC 1gb yesterday using Evga OC tool, Precision and OCCT. I didn't have any problems with the fan control at all with 260.63. I can hear the fan as I adjust it with precision and if I manually raise the speed I can hear it. While overclocking the card I would set the fan to 70% manually, and then after I found a stable clock that I was happy with I would set the fan on auto and I could hear it slowing down to 30%.
 
How ever, a couple of times while doing this I noticed that the precision slider would drop down to 30% but the fan was running at 70%. So I would raise the slider again to 70% and hit apply and then it would stay there. Just the slider was dropping to 30% NOT the fan. But like I said when I would set the fan control on auto the fan would slowly decrease in speed.
 
So really in my experience I had just a minor situation with the slider dropping to 30% after setting the fan to 70% manually. Other than that the driver has been treating me well. I only use my comp for gaming and surfing the web though. Not any folding or photo, video editing or anything like that.

 


Yeah the driver in terms of performance has been treating me very well. I have had no BSOD problems and no stuttering problems. I even have way more performance then I did before.


The only problem I have is the fan problem.... Jerkin John and RAT-boy it seems that we are all having similar problems with these drivers. To somewhat with saying that it makes me feel a little better knowing that I am not the only one.


So I guess I will have to wait for the Non-Beta version to get it fixed hopefully :)


Thanx guys.

I've got a very, very, very strange new problem: today i wanted to play a round of Race Driver Grid. Before it worked very well with 258.96, even with very high settings. So i started the game and it needs allready longer to load than with my Athlon X2/GTS 250 computer   I tought ok, maybe it's nothing. But than i started for testing a single race, so no other cars. What happend: it was not a really stuttering, more a short freezing for 1-2s. The strange thing: if i stopped the game a moment or restarted it, than it was ok, also when i raced more than one round, than it was from second round ok
It's real strange, i never had it before. So i tought, maybe should try the old one (258.96) again and look, if it's really because of the driver. But what happend now: even with the old one it don't runs good anymore It's really crazy, don't know the reason. But other games like NfS Shift or SBK 09 runs very good, it's only Grid.

i found it was causing me issue in far cry 2, went back to 258.96.

in bad company 2 when it breaks the walls are only a few gray boxes in SP

Seems to be fixed back on the 258s

I think those drivers are weird.. i found out that in bios settings it was booting my other hard drive. I find it very odd it did that on me. I fixed it and made it boot to the 1st hard drive i have. I am running 2 hard drives. This error only happened AFTER i installed the new beta drivers. Kinda weird but the drivers work great anyhow. Can't wait for the full release.

Just started to have a different issue. The fan speed would drop back to auto for no apparent reason. I woke up to find the fan running at 40% and the Temp on my dual monitor setup to be at 90C... Never had this on 258.96. I always set my fan to 86% because of my dual monitor setup.

But anyways, other than this, these are pretty stable in gaming. Can't say for the fan control nor the Folding corruption of the drivers.

The fan fell back to 40% while I was gaming and STAYED THERE... Temps rose to 103C!!! Immediately exited the game so that I don't fry the card.

Now I can't game until WHQL comes out... It's 196.75 all over again.
