You may have oscillator problems and since you don't have I never had any problems with either a solderless breadboard or a prototyped exp-board + wires. Used PICs up to 20 MHz, SX's up to 50 Mhz (with a canned oscillator, not with xtal or resonator). Note: I always use ample decoupling, at least 22..100u on the board, and a 0.1u at each power strip (two if the strips are longer).
