Kirk back home
It seems they might have actually fixed him up. It has spent the entire weekend doing work, mainly Einstein which is particularly memory intensive.
I had a couple of BSOD's but they were caused by GPUgrid and the nvidia driver commiting suicide. I deleted a file out of the GPUgrid slot directory to stop it crashing everytime I started BOINC. When I next started BOINC up it deleted everything to do with GPUgrid. I then had to reattach to the project.
I had this problem with the other machine that has a GTX295. I believe its an issue with cuda 3.1 not knowing which GPU is doing what, as it doesn't happen on my single-gpu machines.
