I have a Gigabyte motherboard- GA-6VX7B-4x, Intel Celleron @766Mhz overclocked@957Mhz and a GeForce4Ti4800se. GREAT graphics card, but i can't get it to work at 4x speed.Although I set the AGP speed to 4x in the BIOS, still in the Windows i get a note that my card's speed is 2x and in PowerStrip3.46 i get this message too.I tried everything but I am not able to fix this.I have a WindowsXP-SP1 and a Via chipset on my motherboard which is probably the problem!If anyone knows the fix to this problem please post it soon.I'm sleeples because of it!Oh yeah, just to say that I had upgraded my BIOS, tryied with the latest Via4-in-1 drivers,some registry fixes I found on the Net and still nothing works!I've installed the latest Via-4in-1 drivers(4.51) and I have the 44.03 Nvidia Graphics drivers!I really can't find the solution for this problem!
