P4G8X Deluxe and Powercolor ATI 9800pro
Hi
I recently bought a Powercolor ATI Radeon 9800Pro graphics card. This card is an AGP8X card, I am running an ASUS P4G8X Deluxe M/B which is an AGP8X M/B. Why do my games lock up if I have my machine set at AGP8X?, if I run the machine at AGP4X everything runs fine. System spec P4G8X Deluxe P4 2.53 1 Gb memory running Dual channel 60gig HD Win XP pro SP1 ( updates up to date) ATI Catalyst 3.9 (problem is not driver dependant) Michael Murfitt |

Whether running at 4X or 8X, the VDDQ I/O voltage is nominally 1.5 volts. The signals themselves only swing 0.8 volts at the 8X rate, but the supply is still 1.5 volts. What you can try, is setting the AGP voltage to 1.6 or 1.7 volts. Sometimes a change like this is enough to make the timing work. If the board had drive strength settings, I'd recommend changing those, but it doesn't have any. HTH, Paul |
