It's been a while since In played with G3DT's but I had pretty much the same problems with an IXMicro card. I solved the wierd screen lines and blurbs by using the video card drivers that came with OS 9, instead of using the ones that come with the video card. The same might apply with ATI's hardware? Another thing it could be is that your PCI clock speed may not be set to work well with the CPU & bus speeds. Maybe moving jumpers around might help. . . . I used to have a table that charted the combinations, and you may still find it out on the web. . . anyone remember where this info is? > What I have noticed is the temp that the G4 runs at.

I used a generic heatsink, and shaved it down to allow mounting a fan on top, while still being able to clear the case lid. Also, take that little roundish clip off the case lid that contacts the stock heatsink to get more clearance- you don't need it IMHO. The important thing about changing out the heatsink with an aftermarket one is to use the stock heatsink clip with it. If you use a different one, it may not exert the correct amount of pressure on the CPU, or it may exert it onto the wrong place. __C -- Chrys R.
