CPU speed and Memory requirements for ArcHydro and Geoprocessing

[MarkBoucher]

I'm wondering what others are using to operate ArcHydro.

I'm getting more and more suspicious that most of the current problems I'm having stem from memory issues.

I've got:

• Windows 7, ArcGIS 10, the latest version of ArcHydro.


• 64-bit


• 4GB RAM


• 300 GHz Duo Core Intel processor


• I'm currently working with a 10' grid DEM 10.2 square miles mask extracted rawdem of 24.41 MB.

Seems like plenty, but is this enough?

This is the same configuration they have given everyone in the Department. I'd need "special dispensation" to get more.

I cant speak for Arc Hydro, but from a computing standpoint 4GB of RAM is pretty low for a modern system.  Its likely that 1-1.5GB of that RAM is being taken up by just Windows 7 processes.  Be glad you dont have Vista as it takes up almost 2gb of RAM just keeping itself going.

RAM is pretty cheap now a days and with 64b windows there is no upper limit on what your machine can use, so if you have the open slots on the motherboard its well worth your time to ask your IT dept. for more.
