Hi
I would like to make the calculation speed up. In order to do so, I installed memories (changed 2GB to 24GB) in my computer. But it looks like the speed did not change so much. I would appreciate it if you could tell me how to make the calculation speed up.
Is it pointless to install much memory to improve the calculation speed?

Hi

if you have a 64 bit OS there should be nothing to do. But not all models speed up that much, its particularly for larger ones. But you must also have a PC that can exchange data between the CPU and the RAM fast enough to really get a speed kick

Good luck

Upgrade to faster CPU/more cores. Faster RAM also seems to help.

Thank you for your comment. I will try to check if my computer can do it or not. Because our license is NFL, I can use another computer which can communicate between CPU and RAM.
Thank you.

Thank you for your comment. Because our license is NFL, I will look for suitable machine in our department too.
