Me ha dado por pensar últimamente que cuando amplié la RAM lo hice sin pensar mucho en cómo iba el tema, y no sé si habrá alguna forma de aumentar el rendimiento (si tengo margen para overclock, si se pueden tocar los timings, si obtendría algún beneficio quitando los módulos más lentos...) La placa base es una Asus P5B, la típica de la época, con socket 775 y DDR2. Tengo 2 módulos de 1 GB (Mushkin) y 2 de 2 GB (A-Data) que creo que son más rápidos. Éste es el informe (resumido) de CPU-Z:
