Quantité de Ram acceptée par carte mère ?

Bonjour

Mon PC tourne avec un Intel(R) Celeron(R) CPU 2.50GHz et 1 Go de Ram.
Lorsque je fais de la retouche photo ou des diaporamas avec Pinnacle; il arrive que le PC plante ou m'affiche un message "mémoire virtuelle insuffisante".
En regardant les posts, j'ai pu voir comment modifier la mémoire virtuelle mais j'ai vu aussi que cela signifie que l'on a pas assez de Ram.
Je oeux rajouter de la mémoire mais quelle quantité de Ram la carte mère peut-elle gérer ? (voir ci-dessous).

Merci
