I currently have 2 GB of RAM [Two 1 GB sticks of Transcend DDR2 800] installed on my Gigabyte MA78GM and AMD 9650 system. These 2 Gigs fall woefully short while working with large scans, so I am thinking of increasing it. I have two RAM slots free. My budget for the upgrade is roughly 2K. My main dilemma is that I have Fedora [64bit] and XP Pro [32 bit] installed. While fedora will support virtually infinite amounts of RAM, XP will cap it at 4 Gigs. Should I: (a) Get two more 1 GB modules and stay within my budget. (b) Go overbudget, get two more 2 GB modules bringing my system to 6 GBs. What are the RAM prices like in Mumbai currently?
