Hi , i´m a Q3 player and i have a G4 450 gigabit (OC) with a PC asus geforce 2 mx in the 2X AGP slot . I wanted to if there is a way to make it 4X AGP ? like overclocking it ?

Thanks .

I'm sorry. but that's crazy talk. it's a port, not a chip. If you can do it, most likely you'll screw up you mobo

sounds like a newbie question i suppose.

actually, theres something about overclocking the bus or something. I'm in the same boat, so if you are some kind of electronics genius, then you go first. i'll look around.

Just to keep the realism, I REALLY DOUBT THIS WOULD EVER BE POSSIBLE. but hey...

edits: this interested me. i checked out some things. on the pc, it seems the frontsidebus determines how fast the cpu can "talk" with the card. agp is 66mhz. overclocking the fsb to 133Mhz sets the agp transfer rate to 89Mhz. overclocking the fsb to 150Mhz is about 100mhz.

using a dual processor daughtercard in a sawtooth g4 necessitates overclocking the bus to 133. i doubt the g4 could be set to 150 though. overclocking the bus would speed the computer up quite a bit, though i know nothing. xlr8yourmac.com will have details i suppose

any hardware gurus out there ready to save the obsoleted?

That is more about the system bus to PCI bus ratio. if you overclock your system bus it will intern boost your PCI clock speed. Now AGP is more like PCI on crack (faster clock speed/data speed) but I doulbt that overclocking an AGP is feasable. You may want to just but a better AGP cad. Becasue it may just be your card is overloaded and the AGP bus is fine or it may be that the AGP bus needs more bandwith.

If your slot is 2x AGP, that's the way it's going to stay! However, if you want a 4x AGP card, they will fit. In fact, 4x AGP cards should be able to work in a 2x AGP slot.

you can speed up an agp2x slot by overclocking the system bus. yes, that what I was getting at.

benchmarks of newer cards show a flat fps rate for most resolutions on agp2x. only on much higher resolutions does the fps change as the card becomes taxed itself. I believe it was around 50fps max on the geforce3 on agp2x.
newer systems (agp4x) get much higher framerates. the card can again become slower than the max that the system can handle.

The point would be to speed up the AGP bus, allowing it to compete with the faster revisions of agp, and to see a benefit to upgrading the video card. 50fps vs. &gt;76fps is a big difference.

there must be a way to speed up the bus, in effect, making a 2x agp port as fast as a 4x.
