I am getting an error while using Region Group on a large dataset. The errors are specified below:

ERROR 010005: Unable to allocate memory.
ERROR 010067: Error in executing grid expression.

I've tried upping my virtual memory as the help menu suggests for the 010005 error, but it doesn't seem to help. I am currently running ArcGIS 9.3.1 SP2. I have 6 gigs of total Ram. The DEM I'm processing has 26240 columns and 14293 rows (approximately 360 mb file size). 5 meter resolution in UTM14 projection. All values = 1 or "nodata". Has anyone found a workaround for this other than having to process in small chunks?
