"Our colleagues from the on-line store theFastest.ru told us that the modification of Sapphire RADEON 9500 with 128MB graphics memory into RADEON 9700 sometimes turned out a failure. Having carried out this experiment with quite a few graphics cards, they discovered that in 30% of all cases the cards worked unstably after the hardware modifications. Moreover, almost nothing depended on the BIOS version (Sapphire or Hercules RADEON 9700) and the working frequencies: these 30% of the cards worked incorrectly in any case with 8 pipelines enabled. The “incorrectness” implies some kind of “rippling effect” in 3D applications made by the falling out pixels. Each graphics card showed its own picture, and sometimes even the whole sets of pixels were missing on the screen."
