I got this weird issue with my friends videocard which is 1Gb version of HD4850 made by biostar. It doesn't drop clocks in idle... always stays at 625Mhz/core and 1000Mhz/memory. I've tried to reinstall the driver - same thing. Any thoughts? here is PC's specs:
CPU: Athlon II x4 620
MoBo: ASRock M3A785GMH/128M
RAM: 4Gb (2x2gb) GSkill Ripjaws ddr3 1333
HDD: 1tb Hitachi 7200
VGA: Biostar 1gb radeon HD4850
