akintayo writes "Digitimes reports that first-tier notebook manufacturers are increasing the standard installed memory from the current 1 GB to 4GB. They claim the move is an attempt to shore up the costs of DRAM chips, which are currently depressed because of a glut in market. The glut is supposedly due to increased manufacturing capacity and the slow adoption of Microsoft's Vista operating system. The proposed move is especially interesting, given that 32-bit Vista and XP cannot access 4 GB of memory. They have a practical 3.1 — 3.3 GB limit. With Vista SP1 it seems that Microsoft has decided to fix the problem by reporting the installed memory rather than the available memory."
