I am looking to get a little extra power out of my lombard. I am thinking of bumping it up to 400MHz from the 333Mhz it is. My question is, is this a drop-in replacement, or do I need to replace the board as well? and if it's a straight drop-in, does ANYONE have a 400Mhz lombard module they would be willing to sell me for a reasonable price (say, $20+ S/h or whatever)?
