I own a Monster I and I burned the first one up playing the Hyperblade game that came with the card. I only installed and played the game long enough to see I didn't want it ...about 15 minutes...but that was long enough to kill the card. I was directly told by Diamond that setting the Performance bar which is found in Monster 3D - Settings to Max is considered overclocking the card. This is not mentioned in either the documentation or the help files and I had done exactly that figuring it was a minor setting and if my card couldn't handle it then it would not run correctly. Diamond did stand behind the warranty and exchanged my card for a new one without any argument or delay. The whole process took six days......not six weeks. On the replacement card I have setup a 486 CPU fan to blow directly on the chip and a digital indoor outdoor thermometer probe suspended above the card to monitor temperature. Running a game will heat things up rather quickly by 3 degrees Celsius. I don't know why they don't just put a heat sink on there and maybe even a fan. Mark >Could be something similar.
