one total system failure later...Thanks, I just tried these, but I didn't get any usable results so far, because the new nVidia drivers completely froze my entire system right after booting.
Several "safe mode" boots later, I am finally back to my old Detonator driver that has been working perfectly fine for years, and I am about to find out whether the memory reservation fixes my problem.
So far, I was only able to observe in the task manager that although I had reserved 1024MB for SH3D, it only used about 500MB - slowly rising during rendering, though (but never exceeding 600MB).
Well, that was before I left for supper and trusted my machine to get through 2-3 hours of rendering without human assistance, and when I returned, I had to rip most of my system apart because I thought some hardware part had been fried for good in the meantime...
Now, I'm up for the next test run - but thanks for posting.
