yes and no. They're 900mhz cpus underclocked to 677mhz. In the latest bios (somehow they're already on the second bios?) you can adjust it back up to 900mhz (set the fsb to 100mhz), but you lose a little battery and, at the moment, it's not completely stable at 900mhz, but it works fine other than that. Hopefully with another BIOS update it'll be properly stable.Are they 900mhz?
