The title is saying all, how to fix that. The card Galaxy 9800GT and drivers that I`m using 177.83_geforce_winvista_64bit_english_whql. The Vista won`t let me go above 700 1750 1100. Above 700 core and 1750 Display driver stopped responding error. Before this card I had Palit 9600gso 768mb I had never seen this error and I have had pushed the card to the max (freezing artifacts). On Galaxy 9800GT even at 1150 (2300 memory) no artifacts but GPU above 700 and the error come up. A have pushed the card to 740 1850 and it is running Vantage no errors but when I play crysis and 3dmark03 the error is constantly showing. And I had never had freezing or restarting. I had a quick look on the net and there are a lot people with same problem and this is not nvidia, ati users have same problem same error message and they are using factory defaults settings.
