I\'m running a 2.8 PIV with 1GB of RAM, XP Home, and leave it on all day, too. Although I\'ve experienced a similar slowdown (2 seconds per time step to 3.25 or so), I haven\'t had the kinds of problems you\'re experiencing. I\'m running BOINC version 4.19, by the way--4.45 kept crashing, and 4.19 is running perfectly smoothly.

I\'m running a 2.80 Celeron PC, 512MB RAM, XP Home Edition. I leave the machine on 24x7.

When running the slab model, I was averaging 3 trickles a day. Since receiving a sulphur model on 9/1, I\'m averaging 1 trickle a day.

In addition to the sulphur model taking twice a long to process a trickle, the BOINC client occasionally stops for no apparent reason. (Getting into the habit of checking Windoze Task Manager to make sure it is still running.)

There\'s a lot of folks out here who are NOT tech weenies and would appreciate some guidance on a) what is happening and b) how to fix it IN SIMPLE ENGLISH.

IMHO, you\'re going to lose folks who throw up their hands and silently slip into the night. No credit = no feedback (RAC) = fewer clients. The project may suffer from fewer clients.
