V5 pci100

[MUDASS]

Hi,  I just realize that my agp jumper is set to pci100 instead of pci66, and the V5 agp is a pci66 pcb device.  Is the V5 running at 66 anyway or some damage may result ?  Note that I'm not having any problems yet of any sort like game compat,freezing or tearing screens...

@MUDASS,

PCI bus speed is 33 mhz, AGP bus speed is 66 mhz, are you sure your not talking about your Front side bus speed ?

Ok, I took a peek back at my mobo book to be sure.  And I mix 1 or 2 thingy.  It's the AGPFS; to set the ratio betwwen the agp bus frequency and the cpu bus frequency.  Default is 2/3 agp to cpu bus. I put it at 1:1.  My cpu bus is at 100mhz now.  And asus said agp bus above 66mhz exceed agp spec for agp interface and are not guaranteed to be stable.  I'm not having problem right now.  I'm using 13mhz dimms Maybe I could higher my fsb ?

your FSB (front side bus) is set at 100Mhz.  2/3 of that is 66Mhz which is the AGP bus speed at 1X.  PCI bus can be 33MHz (usually) OR 66Mhz in some special server type boards.  the voodoo line of chipsets are 66Mhz pci bus parts, so you should have no problems.  1:1 ratio will put the AGP bus to 100Mhz @ 1X which is a little fast, but if you are getting no problems, keep it there.  if you go higher with your FSB, then your PCI devices may suffer (HD, RAM, Modem, Network card etc.)..... you are lucky to have a MB that will throttle ONLY the AGP port speed and not the PCI bus at the same time.

Cool!  Another reason to love ASUS mobo !

My mobo is set to 33mhz for e pci bus and I do use a pci V5 5500, is that causing my problem? Bt I think there is bo way that I could set my mobo to hav 66mhz for e pci bus..

what are your specs?  I think it is your drivers that are at fault.  try OEM 1.04 WHQL drivers first.
