So my Power Mac 7600 has a 300MHz Newertech Maxpowr G3 card installed. Problem is....I can't find an owner's manual online anywhere to set the DIP switch settings. They are all set as on or off... I can't remember, and it shows up in the system profiler as a 335MHz card.

Here's the main problem... it causes the computer to glitch on the screen and it occasionally locks up. If I put the original 120MHz card in, it works fine.

I've already tried OWC and Newer Technology's website with no luck. All they have are the drivers. and I still don't know what ones to download. Hopefully someone can help on this so I can get it running stable.

It's this card - http://www.everymac.com/upgrade_cards/newertech/maxpowr_g3_pci/maxpowr_g3_pci_300.html
