here a win7-64bit box with 8 GB RAM

another way would be gdalwarp the DEM to a projected reference system before importing in a grass location; 

in gdalwarp are some more resampling methods (http://www.gdal.org/gdalwarp.html) 
[without looking in the r.denoise-code which resampling methode is used there]

best regards
