The ASRock ALiveNF5-eSATA2+ Socket AM2 motherboard is based on the nForce 520 chipset and offers many overclocking options for a very good price. It is not only easy to overclock with this board, it is also easy to underclock. For some users with 24/7 PCs it became a sport to underclock processors in order to lower the temperature and to lower the power consumption enormously. It was possible to run an AMD Athlon 64 3000+ Socket AM2 CPU instead of the 1800 MHz underclocked down to 750 MHz and overclocked up to 2790 MHz.
