For the BE6-II it is kinda a toss up. I would maybe go with the 1.1a. If you can see your 1.2 up close and find out if it is a retail Phillipine made chip then I would get that one! If it is a Malay then it is a 50/50 chance of it doing 133fsb. If the latter is the case I would then go with the 1.1a. If you have aboard without the 1/4 divider then I would go with the 1.3GHz cel-t as you can hit 120fsb and still be sitting good for hurtz.
