I do have the same problems. SR1 did fix some of the problems (Like some of the memory issues), that to the point we are able to use P6 now. I feel their will be another Patch for P6 in the future. I did get low on memory, and a BSOD when rendering. P5 had two patches to help smooth things out, although I wasn't satisfied for the system I have, compared to the recommended specs written on the box(s) to use P5 and/or P6.
I lowered my bucket size to 32 to reduce the problem and it helped. Although I am unable to make renders no bigger than 2048x1024. I also checked my Hardware issues as well, like cables, heat problems, power. Helped as well.
