A friend of mine has an Athlon 2000+ w/ ywith 700+mb of 2100 DDR ram. The highest upgrade he can get on the mobo is a 2400+, after that model number the chips start to get higher FSBs, and since he doesn't want to change mobo/ram it seems like the 2400+ is the way to go. I was wondering, however, if he can get say a 2600+ and run it at 266 fsb with a higher multiplier, or something along those lines... any ideas? Thanks ahead of time.
