Having recently upgraded from Vista 32 bit to Win7 64 bit; and, 4GB of RAM to 8 GB of RAM, my system runs great except for two issues: printer didn't work (resolved); and, after a day of WIN7 use, my 1000 watt power supply failed. I swapped out the 1000 watt unit for a 650 watt unit (temporarily) until Antec replaces the failed unit. Again, all works fine.
Now the question: During my last render with the updated system which took 27 hours, I kept my eye on both the CPU usage meter and the RAM usage meter. As before the update, the CPU meter was at 100% during render. However, the RAM meter read from 38 to 41% during render whereas with the 32 bit/4GB of RAM it would read almost 100% when passing over plants and displacements. I thought that with the 64 bit/8GB of RAM, I might be seeing more of a higher usage than only 38 to 41% of RAM. Any thoughts on this? How is progress on making TG2 64 bit efficient?
