played a game on my b3 system(i7930 oc4ghz 12gb ddr3 2ghz@1830mhz ati5850 w7 64bit ultimate)played till turn 226 had ctd(ram use was only 1.26gb at crash) zip created, added saves and folders.
turning the game I had attacked altar and was attacking one of their towns with my supersov & one kid(attack stength of 2027), the town was defned by 30(that is right thirty units/parties(attack rating only 906) here is a pic of the start of the battle

and yes, I did kill all of the defenders in approx 6 battle turns(I did say it was a SUPERSOV and child, and we did not have any aoe spells, just used yitheril bows with sov having 31 combat moves son only 5, both with vengance coating and lots of strength/dex & health)
