it's why the 2500+ is one of the best deals in cpus right now, you take one and clock it at 400 FSB without any multiplier changes, and *voila* you've got a 3200+. can't guarantee, of course, but I've heard that most will do it on stock voltage. of course, you're still having to use pc3200 to clock that high, but pc2700 will work fine with either processor at stock FSB. Then again, who knows, you might be able to get the pc2700 to perform at pc3200, I'm running my Kingston ValueRAM pc2100 at 180 FSB perfectly stable (it was stable at 187, but I don't like to ride the edge of crashing)
