After the disappointing experience with the poor new Win 7 drivers for Fermi (257.xx, which is even worse than the 197.xx driver under Win 7) I tried to run GPUGrid on Ubuntu 10.04.
Results for my GTX470:
7 out 8 work units crashed
1 work unit took 36,791.16 seconds for a 6803 credits task: (http://www.gpugrid.net/workunit.php?wuid=1665624). This took place on a i7-920 on stock speed equipped with one GTX470 stock clocked, BOINC 6.10.17 with setting for 7 cores for CPU crunching in order to have one core for the GPU.
I recognized that the task ran with a CPU usage of about 5% - rather low for a Fermi.

The unit that is running on the machine right now is also extremely slow: After 37 min the progress bar shows 5% - even a GTS 250 under Win 7 is faster. With this speed the GTX470 generates about 16-17k Credits/day :-D

I installed the latest driver 256.35 exactly as decribed in this posting: http://www.gpugrid.net/forum_thread.php?id=2150&nowrap=true#17010

Any ideas what went wrong?

I can only guess, because I don't have a GTX470 or an i7-920, neither do I have or know what mobo you're using. But I've had so many failed WU's on many different Linux Distro's, but Mint Linux 64bit Gnome or KDE, works good for me, I have 4 PC's & if Gnome isn't good KDE works & vice versa. Both 195.36.31 & 195.36.24 work well for me & they also support the GTX470 I wrote a tutorial here:http://liveonc.weebly.com/index.html that makes it easy to clip & paste on to the terminal.

To manually adjust the fan speed (to prevent overheating & increase the chances that WU's don't fail due to high temps). Install via Synaptic, Nvclock & write in terminal $sudo nvclock -f -c 1 -F 99 & ($sudo nvclock -f -c 2 -F 99 if you have a second GPU, 3 if you have three GPU's & so on).

BTW roundup, did you actually follow the steps you pointed to+ Because it doesn't work (for me at least & I even wrote about that in another thread) on Ubuntu 10.04 or Mint Linux 9, there's a different way of upgrading the Nvidia Driver on versions AFTER Ubuntu 9.10 Mint Linux 8. I didn't bother find out, because I was getting way too many errors on Ubuntu 10.04 & Mint Linux 9 no matter what driver I tried using.

I can't edit a thread after 1 hour has past, neither can I delete them.

Try the GPUGRID usb key.

Thanks, Liveonc.
I followed your steps. The only command that changed with Ubuntu 10.04 is 'sudo //etc/init.d/gdm stop' that reads now 'sudo stop gdm'.
I will give it another try with another distro - linux is still a lottery what prevents it from having broad success in the desktop world.

I found the bug (actually my mistake).
In the installing process some questions have to be answered on the console. When you are asked if the driver should install the NVIDIA 32-BIT COMPATIBILITY LIBRARIES You MUST NOT answer 'yes'.
Then it works with Ubuntu 10.04 LTS :-).

To manually adjust the fan speed (to prevent overheating & increase the chances that WU's don't fail due to high temps). Install via Synaptic, Nvclock & write in terminal $sudo nvclock -f -c 1 -F 99 & ($sudo nvclock -f -c 2 -F 99 if you have a second GPU, 3 if you have three GPU's & so on).

This setting brings absolutely no effect. I observed the temps on NVIDIA X SERVER SETTINGS. Fan control type is 'variable' and the fan operates between 51% and 57%. Temps are between 78° and 84°C.
All nvclock settings lead to the following message:

It seems your card isn't officialy supported in NVClock yet.
The reason can be that your card is too new.If you want to try it anyhow [DANGEROUS], use the option -f to force the setting(s).
NVClock will then assume your card is a 'normal', it might be dangerous on other cards.
Also please email the author the pci_id of the card for further investigation.
[Get that value using the -i option].

Even the option -i leads to this message.
Nvclock version is 0.8 beta4. Is there a newer one available (maybe a release that allows for some oc'ing)?

I expect NVClock does not work for Fermi cards, as it is based on the previous generation of architectures. Up to GT200 series only.

Does the Linux x86_64 256.35 Driver not have a built in OverClocking feature (Something equivalent to NVidia Control Panel)?

- I would check myself, but it would mean installing Linux, the driver and not crunching for a day.

Hi skgiven,

nobody says you have to stick to Windows or spend an entire day on Linux. Just use Wubi if you want an easy way to quickly install within Windows & remove also with Windows quickly. I'd do it too but Ubuntu 10.04 doesn't like my PC's.

Hi Liveonc,
Can you alter the shaders speeds via NVidia X Server Settings on any of you Linux systems?

Hi Skgiven,

I haven't tried I like to flash my GPU instead.

But you're supposed to add:

Option "Coolbits" "1"

$sudo gedit (kate for kde or mousepad for xfce) /etc/X11/xorg.conf

to: Section "Device"

BTW, I haven't tried myself so I'm not sure. nvclock isn't even needed for this, but I need nvclock to set my fan to 99%

with coolbits you just run in terminal

$nvidia-settings --assign="GPU3DClockFreqs=676,1457"

if fx you OC to what I use on my GTX260's

Again I'm not sure, I haven't tried, nor do i need to.
