Climate model on a mac Project #8: Memory Upgrade...
The minimum ram requirement for the climate model was 2 gig, which is what came with the computer. However, I decided to get 8 more gig for the system. At first, I left the original 2 gig in the machine (arranged according to the docs). However, this caused an enormous performance hit: the system was 12% slower running the model. Dropping the original 2 gig brought the speed back up, more or less, to my original performance figures. I’m still not sure that this was a memory arrangement problem or a mixed-card-size problem…
