La ram che ha ora è Elpida 2GB PC3-10600 DDR3-1333MHz non ECC Unbuffered CL9
e ho acquistato questo ram Kingston 8GB Kit (2 X 4GB) PC3-10600 DDR3-1333MHz non ECC Unbuffered CL9
Il problema è che il laptop non si avvia. Quando si preme il pulsante, viene visualizzato il logo del vaio e quindi si riavvia, e di nuovo ecc.
Il problema è la memoria che ho acquistato o ne ho preso uno sbagliato?
