Aki os pego lo q pone:
so many many many people open threads about "card chrases" etc...
so here is a little guide for all angry people to look before opening a new thread (perhaps should go sticky )
card crash:
- try agp voltage in bios up to 1.7 (should fix 95 % of the problems)..try 1.8 if 1.7 did not function
- install all the latest motherbard bios
- run in agp 4x mode (powerstrip or even with the smartbus) (should fix chrases in 98%, I run in agp 4x mode, there is no certain perfomance loose and you don't have to set up your card to 1.7 agp voltage)
- uninstall ati drivers , then install directx 9, after that the ati cat 3.0 drivers
- minimum 300 watt power supply (even some guys have no problems with 250 watt, so it is a question of other components in your system)
- try not to share the power cable of the ati card with many other devices
- do not share irq of the ati card with other devices (seems to be a big problem especially with soundblaster cards)
- use no card on pci 1 slot (next to agp slot) , look in your motherboard guide which slot also shares irq with agp slot
- the ati card gets very hot, so you look if the card has enough air
A mi me valio con lo del AGP a 4X, haced lo q os de la real gana. Un saludo.
