Hola amigos.
Primero agradecer al Webmaster que completase las dudas que quedaban tras la ayuda de merlinpat :-*
El tema es que me gustaría saber cómo puedo conocer la RAM real que una tarjeta gráfica tiene. Cuando vas a una tienda suele poner: "hasta 256Mb" "hasta 512" etc. pero no me gustaría saber cómo sé cuánto tiene realmente dedicado. Que si no me equivoco es de lo más importante y que es algo así como la que tiene fija para ello.
En éste caso sería una tarjeta gráfica ATI Mobility Radeon X2300; aunque me gustaría saber el sistema, o dónde aparece en el manual, para cualquier tarjeta gráfica y así no tener que volver a preguntarlo.
Me he metido en la web y he sacado esta información.
Gracias a todos por vuestra ayuda.
