Diamond V770Ultra owners

[RallyKid]

I finally got a mobo that supports 4X AGP, ut I lost all my papers to the Video card. So my question, which jumper/s control 4x function on this thing?

Thanks

First of all, i don't own or have owned a v770ultra. (i guess is the Diamond TNT2 Ultra right?)

As far as i know, there's no jumper in the video card to turn on agp4x, agp speed is automatically set by the mobo, and can be changed with some drivers.

However, there's no real world performance gain (if there is some) by using 4x instead of 2x.

Yes, There are jumper settings on the card to enable AGP 4x.

performance jump isn't significant though. I set my Viper V770 (non-ultra) to AGP 4x...no big performance increase, but no problems either.
