I am now going to upgrade my memory of SZ 160P/C.
I want to upgrade to DDR2-667 instead of orginal DDR2-533.
But I only can find two :
1. kingston M12864E40 1G DDR2-533
2.Corsair CMSS1GB-533SOD 1G DDR2-533
sony said it is 1G DDR2-667.
I am not sure it is composed of 2x512M or 1x1G.
I hope it is 1x1G.
and I also want to know the diference between SZ150 and Sz160, the specification are the same in sony.com.
