I'm having problems getting a Hercules 3D Prophet DDR-DVI to run 3D without crashing. I think it could be caused by my crappy MB, an M726 (ALi 1621 chipset). I'm using the latest ALi AGP drivers (1.69) and Nvidia 6.18 drivers.
When the card is set to run in AGP2x mode it will crash at the start of anything 3D. When set to AGP1x the card will run 3D for a little bit before crashing. I can run the DirectX diagnostics program just fine in this mode. When I start Q3A using the fastest 3D settings, it will run fine. When using the normal setting it will crash after a few seconds. All higher modes will crash at start.
What could be causing this? Could the less complex 3D programs be using less power? If the problem is that my MB can't supply the board with a clean power source, could this be the reason that less complex 3D works?
Along this line of thought, I tried underclocking the board. If the board is clocked lower it should be using less power. It almost works now. At the lowest setting a can clock the card to (using coolbits reg hack), 99.9% of the time 3D runs ok. The thing is, I dont want to run the card at 105/270.
Is the power explanaion right, or is this board just messed up? Could the GPU or memmory be fried? Anybody have any ideas? Thanks in advance for the help.
