Thanks for the tip. Going back to 196.21 did not change the temp for me; currently running at 66C and 47% fan speed on my GT240 on P10105. That is perfectly OK of course, nothing to get excited about. I think my original problem with the higher CPU usage was due to the fact that I also use a Radeon 4350 as my display card, and fold only on the GT240. There may have been some interaction between the cards. But I removed the 4350 from its slot and connected the monitor to the GT240 in order to initialize everything properly, then re-inserted the 4350 and connected the monitor back to it, with a dummy plug for the GT240. Now my CPU usage is back down to 2-3% where it belongs, so problem solved. But I will try out the new fixed drivers when they arrive also.

I posted a news on FAH-Addict : nVidia drivers 196.75 are potentially dangerous!

Does anyone noticed this problem with FAH ? If yes, I guess it might be worth a global announcement ... I wouldn't like to see people killing their boards because of this ...

These 196.75 drivers, I do not like, I do not like, Sam I am.

In my Windows 7 x64 + GTX 295 + 9600 GSO I'm getting the behavior again where the GTX 295 GPUs fold along at 7,000 - 8,000 PPD for a while, like half a day and then this morning woth the computer utouched all night, I find they've dropped to 64 PPD on one GPU and 35 PPD on the other! That's over 200 times slower! I suspect the culprit is Multi-GPU (SLI) enabled, but I can't disable Multi-GPU (SLI) with this driver version since it messes up the desktop and makes Windows, the entire computer unusable and sometimes non-responsive.

I'm going back to the official CUDA 2.3 drivers.

With the Ofiicial CUDA 2.3, my process is:

    Disable Multi-GPU (SLI) (causes 8000 to 40 PPD slowdowns after hours of folding or waking up the monitor? Is this a 3D to 2D mode issue?)
    Install all of the Nvidia System Tools
    Run Nvidia Performance to set and save Overclock and then leave it closed - others are probably using better OC tools
    DON'T run Nvidia System Monitor to watch temps - It gave me EUE's as I recall!!! :(
    Make sure Nvidia update is disabled, it never caused problem, but then again I never ran it!!

Trying to get 196.75 running reliably has wasted a day's time and frustration and cost 3 days worth of folding science. Then I see from the previous post that they are recalling the drivers. Cute. Just because they release a new version of drivers doesn't mean they will work, and now it seems they can possibly fry your card!!! Fortunately for me, I've been using manual fan control at 100%, so at least my cards didn't get fried.

Official NVIDIA Forceware 196.75 display driver feedback thread - fan control broken - 105C
There is a MAJOR problem with this driver.

The automatic fan control is somehow diabled with this driver.

My normal idle temperatures on my GTX 280 is 45/46 C and load temperatures are ~70C.

I was playing a game when I started feeling very warm. I thought this was very strange and decided to look at the GPU temp. I was literally shocked when I saw that my GPU temp was at 105 C !!! I reverted to the previous driver to 196.75 and got back my normal GPU temperatures.

There could have been damage done to my card because of this driver. I am very unpleased with Nvidia. How in the world can this driver been released with this problem? Do they test things before they ship it out or no. Imagine how many cards that will be fried from this driver... I am sure Nvidia will not take responsiblity for this problem


If you're concerned read the whole thread at Nvidia and see what you find believable. Some are saying that their cards are smelling burned and a few cases of exlpoding chips sending tiny electronic debris - at any rate read the thread if you're interested and judge for yourself:

Yes, I'd say a general recall notice and DO NOT USE for 196.75 is in order!

I have edited the title accordingly.

nVidia acknowledged the issue ... so I updated my news to reflect it.

I've always had temperature problems with my GTX 295 when running FAH clients on both GPU's. Nvidia's drivers never seem to get the fan speed up above 70% no matter what the card temp is. I have to load up something like Riva Tuner to force the fan to 100% in order to keep the GPU temps somewhat sane. This has been true no matter WHAT version of driver I'm using.

I've been using the NVIDIA Performance Group add-on to the NVIDIA Control Panel from the NVIDIA System Tools to set the fan speed on my GTX 295 to 100%. The fan setting is only enabled for one of the two GPUs in the card. There's only one fan on the GTX 295 that I have.

You do have to make sure to save the profile or make sure it gets applied on restart so that when you restart the computer the change is appied. Mine's a dedicated folder and it's in another cube, so I can leave the fans at 100% and the newer single Printed Circuit Board (PCB) GTX 295 isn't that loud, even with the fan at 100%. I set the fan at 100%, much higher than the default profile would set it, since I prefer the card run cooler and hopefully last a little longer.

It's also possible that the fan control on your GTX 295 is different from mine if the cards are different vendors or models. For example, on some of my 9600 GSO's from different vendors - some allow fan speed control and others don't.

If you have the option, you might also help the cooling by taking the side panel of the case off - if that's an option for you. I have the side panel off of one of my systems and a Vornado fan parked next to it blowing directly on the PCIe slots and graphics cards. Probably a good 10 C or more cooler than a typical case with covers on. Something like that might be cooler with the fans at 70% than with the case cover on at 100%.

I think I'm going to start using RivaTuner though, since the various Nvidia utilities have caused me a number of issues, some of which I mentioned before.

should make an sticky for this as it is important as the fan does not work correctly or at all in some cases with 196.75 driver (an new thread as this topic is related to an different problem)

Note from Mod: Topic stickied.

It appears that Nvidia has released a new set of drivers (v. 197.13) addressing the speed bug.

I have downloaded the new 197.13 drivers and will see how they go, maybe they can help with
small dotting as well?

Hi,

Can someone help me with some info. I have a new GTX 470 and used the latest driver and F@H won't work.
It keeps showing "Core not running", and uses the test protein. Is it me or the client?


Thanks for your help!
