I have problem with His 9600 256/128 vivo. it shows some lines on desktop in games and while booting lines are on the all screen mixed colours. First I reduce hardware acceleration that fix problems, Then I flashed with 9600 128/128 and lines disappeard and after several weeks lines shows again help. PS I didn't overclock my card ever. Can I reduce some short or resistance on card to half memory from 256 to 128!! Help!!!
