AGP bus, voltage, core/mem speeds?

[DeathONator]

Ok, I'm still a newb at ocing graphics cards. Learn me some stuff.

1) Does upping your video card's voltage help in raising it's core/mem overclock, pumping it a higher FSB, or both?

2) Is AGP FSB kinda like memory timing and memory FSB? I mean how much does upping the AGP bus help? Will that lower your core/core speed? Does AGP bus add more heat to the graphics card?

Please, add anything else that would be helpful.

I am still somewhat of a video card overclocking newbie myself, so I certainly don't know all the answers.

1. Upping the AGP voltage really does not help. The reason is that the video card has its own voltage regulators on the card, which regulate the voltage to the GPU and the VC memory. That is why you read about people performing volt-mods to their video cards, so that they can in fact raise the voltage to the GPU and memory.

2. I'm not really sure about the AGP bus speed issue. I would think that IF the AGP bus was the bottleneck, then raising the bus speed would definitely help. However, you probably have to overclock your video card a lot before the AGP bus becomes the bottleneck. You can always try increasing it and see if it helps any.

agreed.....bus speed overclocking doesn't do that much to performance and hell...i cant even boot past stock anyway :P (66mhz)
