Is there a way I can use different activity settings for different computers? One has adequate cooling to continue using 100% of the CPU time and 100% of the GPU time, but the one I'm thinking of adding is a laptop and not likely to have cooling adequate for the same settings.

I've already set up the settings I want to try on the other machine under the School profile, but I don't see any way to tell GPUGRID on that machine to use the School profile for GPUGRID work, but let my other machine continue using the Default profile instead.

From your account screen select view computers, click on details for the one you want to change, then scroll down to the drop down box for location.

That worked, but I've found that Nvidia says that the GPU in the new computer must use a rather old version of the driver until HP (instead of Nvidia) provides a replacement. Also, the Nvidia card in that computer is one that GPUGRID does not recommend using on GPUGRID due to its small number of processors. I'm still waiting for an answer to my question in another thread about whether the longer deadline times GPUGRID now uses moves it (a GeForce G105M) into being more suitable.

The slower GPUs can be used on MW and Collatz as two alternatives besides SaH. The best thing about those two projects is that for the moment at least they are completely agnostic and have applications, if done only by volunteer effort, for all current Resources ... um, well, MW needs DP math and your lower end may not be suitable there ... but that still leaves Collatz ...

Thanks, I'll check those projects.

Be advised that based on my experience the 9800 is about 1/3 the speed of 260 and above cards so here on GPU grid 6 hour tasks take about 17+ hours on the 9800GT (which is why mine will be retired to standby in case of death mode).

About 19 hours on my 9800GT. I've thought of buying a new Nvidia card, but I'm not sure I'd still be able to handle installing one.

Do you mean the GTX260? Other messages say most boards of that model do NOT work well with GPUGRID.

I'm already thinking of asking the local Best Buy if they can handle the installation. They don't have a suitable Nvidia card, but a Best Buy online order location elsewhere does.

After a stroke a few years ago, I doubt if I can still handle lifting either of my desktops onto a table; something needed before checking what Nvidia cards will even fit.

All the Nvidia Cards are double wide (2 slots) and slightly longer than the 9800GT I can go measure if you like ...

Like I said, the real key is the PSU, second is box size.

I now have enough trouble even moving the cases enough to open them that I'm not sure whether I can do anything useful with such measurements.

I suspect that at least one of my desktops will need a new PSU if it gets a new GPU card, and the box sizes need to be compared to what is needed, and the cases need to be checked for adequate cooling.

In other words, I expect to be slower getting much done than those who can handle the cases themselves.
