I just git the Daytona Geforce2 mx and it has a heatsink and fan.I can get the core to 220 stable probably higher but thats all the slider goes to.The 6ns memory is a differant story.Before overclocking i noticed that the core was at 175 amd the mem at 150.Anyway the mem wont even go to 155 before i get the screan all garbled up.I atleast want it at 166 where it should be.6ns mem should do it.152 is as high as it will go.it also pisses me off that Daytona is shiping the cards with the mem set at 150 thats under Nvidia specs for this card.
