What are the >specs of your setup? I have a Celeron 1200 with 1280MB ram, I usually use 832MB for hash and was suprised that I needed more nodes than you, so I suspected that you used a very large hashtable. When I get home, I will try it with 384MB hash and report again then. I also run my system on WinXP. Ernst.
