The flickering is a common occurrence with ALL (...yes all) VGA cards that are overclocked by default by the manufacturer beyond the recommended 900 MHz memory clock. This phenomenon happens regardless of the chosen PCB manufacturer (Asus, Gigabyte, XFX, Powercolor, Sapphire, HIS and so on) when the operating system switches profiles within the graphic card. This is done to adjust performance settings according to the users interaction with the system by consuming less power at off-peak thus prolonging the VGA service life.
Ovde Jeff kaže da treba uraditi sledeće:
- Undo whatever (damaging) procedure you have done so far
- CLEAN Install the latest drivers (FROM ATI®)
- Enable ATI Overdrive™ (bypass the confirmation prompt)
- Underclock your „Memory Clock” to 900 MHz
- Apply changes
Dakle smanjiti frekvenciju na 900 MHz. Ako ni to ne resava problem,probaj da update-ujes graphic card's BIOS (VGABIOS)
