Memory Vs Render time correlation


Recommended Posts

Hi Guys, I was just wondering, with the cost of memory so cheap these days, if anyone had studied the effect of having more memory in their computer against the time it saves them?

 

It occured to me today (doing an incredibly large render) that if the correlation was as dramatic as twice as much memory twice the speed of the render, then it almost is imperative that I spend a mere £100 or so, and almost double my work efficiency.

 

what are your thoughts or comments?

As soon as your computer starts swapping memory from ram to hd, it will slow down considerably. So the optimal amount of ram is not "more" but "enough". Check memory usage during a typical rendering, if all runs in ram you're fine. If not, add the amount of ram that is being swapped to disk.

I guess the MAX render dialog indicated the memory being used for a the rendering. As sicro said, the memory indicated in MAX must not be more than your RAM for optimum performance. Also the map shadow sometimes require more than 512M. I personally experienced major efficiency changes with 1gb over 512 for "more than normal" renders.

thanks

i agree with rest, how ever increasing the ram, not only speed up the rendering but imprves your workflow. allowing you to run more appz at once

yes, it certainloy improves the work flow, but it doesnt speed up the rendering. not unless you were too low on RAM in the first place.
