It's not a problem. You have a 9800GTX+ like mine, so BOINC is probably telling you that each task will take a couple of hours, right?

In fact, that's a mistake by the project. Even the quickest tasks will take at least nine hours on that card, and the longer ones up to 14 hours. (Your GIANNI tasks are likely to be in between those extremes).

This project likes to have the tasks returned quickly, if at all possible. Hence the deadline of five days - but you also get a bonus of extra credit for returning them within two days.

Sticking to a couple of tasks at a time is a good idea. You'll see why when you complete your first task, and BOINC corrects that faulty project estimate.

The card is the same as mine - a 9800GTX+

On initial joining the Project limits the number of WUs to one per cpu as a crude rule of thumb limitation. Once the first ones are returned the limit is lifted quickly to around 15 a day. However you will only need 2 perday with a 9800GTX+.

Easiest way is to set preferences cache to 0.1, then leave it to do its own thing. It will download a replacement about 2 hours before the last finishes. You dont need a large cache as the server here is good, very little down time, its rare that it goes down for any long period of time.

The reference to "not of the type" etc is a BOINC thing, not the project, its telling you what you already know - you cant run a cpu app here (!). Its a quirk of the way BOINC schedular is programmed. GPUGRID are hoping to bring on line a cpu app in the not too distant future, so even that irritant will go away. Ignore the "of your type of PC" messages when you get them - spurious.

Regards
Zy

Apparently right now you can only have 2 WUs for each CUDA device. Send one back and you'll get another.

What does not work? We only told you that this is a hard limit and that it's OK for your card (a cache of ~24h running GPU-Grid 24/7). There's no way around this except changing hardware.
And apparently you already got 4 WUs, so what's the point?

Help. I got my first card installed XFX 9800 GTX+, and Boinc is giving me this message:

Note for admin: that message is outdated. It should say "driver version 18585 or later needed".

It'll be called 185.85 on the Nvidia driver download page, which is where you need to go to download them.

For me 185.68 worked very well, so I'd write "driver version >=185 needed". But thanks for the note, this message should really be updated.
