Diamond Viper Resource Page

Special Notice

If you own a Viper V330, V550, V770 or II you have come to the wrong place. This web site is for the older (circa 1993-96) cards. For some reason Diamond has re-used the Viper name for its latest range of high performance cards, which is very confusing!. I am not able to answer any queries about thes newer cards. If you need help I suggest looking at Diamond Multimedia's web site instead. Thank you.


I have set up this page as a central repository of information and resources for owners of the original Diamond Viper graphics cards. These Vipers were once a family of high performance VRAM based video cards using the Weitek Power9x00 chipset, common around the early 1990s
