Vista -- the new and the most talked about Operating System (OS) from Microsoft -- has received mixed reviews. Users have genuine complains but it isn’t stopping PC and notebook makers from installing it in the new sets. There was an interesting article in PC-Stats.com about how much memory is enough for Microsoft’s Vista. According to it, generally one does not require a hardware overhauling when an OS is installed but with Vista, everything needs a refurbish, so that the blue-eyed Vista baby functions without any jerk. But, still the problem persists …

According to the article: Vista's minimum memory requirement is 512MB, however even if you upgrade it to that, pragmatically you need double the RAM to run it smoothly. The Microsoft’s Windows Experience Index scored only 1.7 points, even for 2D office/workstation there was noticeable lag. However, with 1 GB addition -- things improved and documents work productivity increased and even the games responded well, and with 2GB the Windows Experience Index increased by three times. Though 2GB did not make much difference to office tasks, as it is mainly user limited, the games got a boost.

If you have a 512 MB RAM, and Vista says it is sufficient, IGNORE ITS WORDS, for better and no hazy experience, you need at least 1GB of memory.
