- In regards to the "snow" problem with the Paradise (or virtually any card)
- the permanent solution is to replace the RAMDAC with an equivalent RAMDAC
- preferably of a different brand. The way some older RAMDACS handle color
- cycling causes "snow" to appear. Just make sure the speed rating of the
- replacement RAMDAC is the same speed or higher.
-
- On most paradise cards, the RAMDAC is a socketed 28-pin DIP package which
- looks like a ROM chip, only without the label tape on it.
- If the chip isn't socketed (most are), then you're out of luck. Don't
- try to desolder one of those multilayer jobs...you'll usually regret it.
-
- By the way, for people whose video cards seem to have these ugly alternating
- light-dark thin vertical stripes on the screen, a RAMDAC replacement will
- generally solve that problem as well.
