My understanding is that *reducing* tile sizes<br>only has a positive effect with regards to reducing the size of the output<br>buffer, which is in most cases is a rather small part of the total RAM eaten<br>by Cycles, and thus, unless you you're in a desperate<br>I-only-need-10MB-more-RAM-to-render-on-my-GPU scenario, increasing the tile<br>size for speed benefits is the more likely scenario.
