Alpha LDP board had only 133MHz rated memory on them. These were quickly replaced with beta then production boards with 166MHz rated memory.
Probably only a few dumpsters at TI have 133MHz restricted alpha boards (and maybe at logicpd). I don’t' think you will even find an alpha in plastics.
Nothing stops a person from running at 133 on the 166 rated parts. But most won't choose to on a 3430.
