- Hmmm... There are two major RAMDACs for the mach32 cards:
-
- ATI68830 up to 80MHz PCLK
- ATI68875 up to 135MHz PCLK
-
- I would gues you are using a card with the first one (just look at
- your board and read the number on the second big IC). To get 1280x1024
- non interlaced you would need a PLCK of at least 110MHz. The 68830
- won't do that. Hence they recommended you to upgrade to the 68875.
- But I don't know whether this is possible (these RAMDACs might not
- have the same pinout ...).
-
- Btw, the Ultra Pro is running fine in 1280x1024, althought I'm a
- little bit disappointed by the image on the screen. It not very sharp,
- at laest not that sharp how other 1280x1024 boards ...
-
- Also I'm a little bit surprised about the performance of the new
- boards. I did expect quite a bit more from the new mach32 given the
- time ATI had to do the chip. I'm running X, and the mach8 gave me
- 85k xstones, while the mach32 gives me around 100k xstones ... Hence
- let's wait for new faster boards ...
