Dont.. that is just..at least 3GB i personally use 10Gb but it also depends on the type of hardware you have
x64 will/should still not use anything above 3-4GB. x128 might have to go near or slightly above 4GB mark for something as the DW20 pack.well see thats were i use most my ram i use alot of texture packs that are 64x or 128x
Well it is not just my personal opinion. If you look around the forum you will find the vast majority of people warning about this. You should always try to make due with the least amount of RAM allocated to the game as possible(with a certain margin ofc for stability) and try and keep it under the 4GB mark. Only if you are forced to go above 4GB due to something like x128-512 texturepacks etc. should you do so, and in that case only if you take steps in form of JAVA arguments to better garbage handling or possible even secondary programs to deal with the problems it arise.to each his own then
...seriously a lot of people are getting ripped off buying 16-32GB(which they will never use)...
RAM is and never has been a performance parameter. After you have enough, then more will not help one bit...

More memory can be useful... Outside the game. For example, in the days of DOS when you needed special drivers to be able to use more than 640K ram, we used the extra ram between 640k-1MB to stuff drivers into, and anything above that as a Ramdisk. We'd actually copy the game to the ramdisk where it ran faster because of ram access times and not having to bother with rotational delay and seek time.
Technically this concept should still work, perhaps even better since we now have direct access to the upper ram... Judging from the specifications I've seen for SSDs a ramdisk could easily outperform one.
1.7.1 at this point in time, runs better for me than any version of minecraft has. Except vanilla of course.
