overclocking 133 FSB AMD boards

[X14]

When you over clock AMD 133 FSB boards, at what FSB must you disable 4x AGP?

At whatever speed causes 4x to lock your video. You'll know when you hit it.

It will usually depend on the video card being used. My Radeon 64mb VIVO works just fine with AGP 4X with a FSB of 165mhz, but my old GF2 GTS would quit around 160mhz FSB. The new GF3's seem to be even less tolerant of high FSB/AGP speeds, and I have heard you need to disable 4X to go much over ~150mhz...

I read somewhere that some vcards can't run 4x AGP on FSB speeds higher than 137 or so.

Most newer card will handle at least 150mhz...
