how far did you get with your Ti200?

[DinoGucci]

i have a chaintech Ti200 128MB gold plated very nice card. looks realy good. i am wondering how far can i get with my card. so far i have it clocked up to 200/450 but i notice lock ups if i go higher. i was wondering what Ti200 owners have done with this card to get a full benefit. or even suggest what to do. thanks !
