agp 4x abit ka7 diamond viper v770ultra

[blakbas]

i have been trying to get 4x to run with the v770ultra using the abit ka7. there is a option in the bios for 2 or 4x, but when 4x is selected pcinfo program states the card is running in 2x only. although it does say 4x capable. any ideas of what i am missing to get this to work

thnx

Have you set the jumpers on the video card to 4x? I think that there are 4 jumpers on the video card that each need to be set to run in 4x mode.

There should have been a little manual explaining how to do it in the box. You need to set Jumper J4 (which is in the upper left part of the board) from AB (the two pins nearest the top of the board) to BC. You also need to close jumpers J1, J2, and J3 (all three are near the bottom of the board). My board didn't have extra jumpers for those three, so you may need to track some down.
