ATI 5700 / 5800 problems thread

[Mungri]

Hi. I decided to create this thread due to a widely reported problem on the 5770s over at AMD game forums, that has also affected me.

The cards are fully stable and rock solid reliable in 3D mode and never have any crashes or problems while under heavy load.

However, in 2D mode, when they are downclocked to 157/300, some users including myself are having a problem where windows / internet / anything in 2D while running at 157/300 is crashing with a computer freeze and artifacts all over the screen.

About 25% of the time, the Catalyst driver manages to recover, but most of the time the PC needs to be restarted.

Yet under load at full speed and normal voltage, the cards have no problems at all, signifying that this cant be a hardware fault, but a powerplay / driver / 2D state problem.

RMAing the cards will only be a last case option, as I would like to keep the ones I have as they clock brilliantly and otherwise work fine.

If anyone else has this problem, or any other, then please report it here.
