a All of the Athlon(with "Thunderbird" core), AthlonMP and AthlonXP(with "Palomino" core) CPUs of AMD are socket 462 (socket A) and operating at 266MHz Front Side Bus(FSB).

b The DIMM1 and DIMM3 of the memory banks on the MIS K7N420PRO are filled to enable the maximum bandwidth of the dual-channel DDR.
