Guys I have a Biostar 5570 in my old rig[the full height version]. For the past week I am experience random artifacts that fill up the whole screen, they are small rectangles. then the computer locks and VPU recover resets the driver, sometimes it does not and I have to hard reboot. It first happened during balck ops, then in Hot pursuit and now happens everywhere even in Counter Strike 1.6 and the normal desktop too!
I just took it out and looked around, and I saw this -
Is this component blown up? Can this cause the artifacting problem?
It is on stock clocks, and the temps of the GPU are 45-46 on idle and around 75 under load. When these artifacts come up and VPU recover does not reset the GPU, If i lower or higher the memory clock even by 5, the artifacts go away and then i bring it back to defaults and it runs fine for a few minutes, sometimes hours. It is really frustrating when you are playing a game and it locks up.
There is no help here aside from getting a new video card. Since it seems lowering the speeds just a tiny bit you are OK, run it that way. Loosing 5, 10 in clock speeds will give you absolutely no differences in games.
What hang the 9 said is absolutely right, but if you were confident you could try oven baking your card. I hear that fixes some cards with artifacts. I'd rather go with the above post first personally.
I would just RMA it if you can. If you want to bake it though,
1: remove heatsink and thermal paste
2: preheat oven to 385F to 400F( NO HIGHER!) ( gas mark 6)
3: lay foil over the oven rack
4: make 4 balls of foil, about 4cm high,
5L when the oven is heated to its corrent temperature, put the graphics card on the 4 balls, one on each corner )
6: leave for around 6-10 mins, NO MORE THAN 12 OR IT WILL MELT
