How do you measure how much video memory is used?
We think that there is a bug in the driver, this would be the best way to show it.

I use Rivatuner. With loaded plugin vidmem.dll the program can show the actual video memory consumption. On a fresh startet XP 64 the first WU use 70.32 MB. If the second WU is started, 138.63 MB are shown as used. The next WU shows 206.88, then 275.57 MB, then 343.82 MB and so on. On the third day all video memory is used and every WU will crash.

Install RivaTuner, click on this strange "button with a triangle" next to the line which tells you the physical details of your card, then search for the hardware monitoring in the list of symbols, which pops up and if it asks, tell it to "handle the plugins automatically". This should enable the vid mem module.. at least it did for me :)
(it also shows 70+ MB consumed with desktop + GPU-Grid for me)

@Koko: you'd get a problem if the bug is not resolved and the number of steps per WU is reduced. I think just reducing the deadline is not what is dicussed here and would not lead to problems on your side anyway ;)

@GDF: would it be feasible to dynamically adjust the number of steps in each WU to support slower cards? I could imagine a system similar to Rosetta@home, where there is a user setting for how long the WUs should run (=number of Monte Carlo runs in their case). The default is a few hours so the server is not overloaded.

I know this would require quite some additional work, but it may be an elegant long-term solution, satisfying power users and owners of slower cards. Plus if at some point you set the amount of concurrent WUs per GPU to 2, people with limited inet connectivity could make up for that by setting longer run times.

@ETA: On this one XP64 machine is also installed a Vista 64, so I can use Vista and avoid this problem. But at the moment I use XP and know, that I have to restart every 2 days. When I'm longer absent, I switch to Vista.
