I did change the 10.5.2 forcedeth version for the regular one. Slower network but no crashes so far. I just dont hit the 1mb speed at the torrent yet, but by http I downloaded at 102Kb/s and it was ok. Still looking for a decent torrent for download at full speed to see what happens.

edit: no overclock in my system.
system: amd 3500+ venice, a8n sli se (sux), 2gb ddr 400 samsung, 20gb ide 133 for osx, 200gb ide for files, 2x prolink 6600gt 128mb (sli not enable at osx, is it possible to enable that?) 1mb connection.
