From: yoxoman on 25 Mar 2010 02:52 Hello, I was asking myself about the kind of optimization that permitted bus frequency speed increase on motherboards through history (ISA, PCI, AGP, PCI-Express...) ? - Material quality of connections between component ? - Spatial considerations ? - Increase of information quantity playing with clock ? - Anything else ? In particular, is it possible to play with the material quality used on motherboard (or any card) for connection between components to increase performance, or is it optimal yet ? Thanks.

The mother board material is important at high frequency. see "loss tangent". Gore makes the very best board material out of GoreTex. (they can send me a rainsuit for the plug. :-) ) Only problem is Goretex boards are difficult to manufacture, and are expensive. Epoxy fiberglass isn't bad if you buy the right stuff. Circuits getting a lot faster was a big help. |
