I've looked at the framebuffer FAQ, and it states that a 501-3129 75 Mhz creator 3d only works in ultra 1 200E's and ultra 2's >= 200mhz. is this true? I suspect it may be as I can't get my 170E to drive this board :( is there a possible workaround? or do I need to have the company I got these from find me the 66 mhz version???
