Most newer computers will have more than I GB of RAM and, in most cases, there is sufficient RAM available that having more virtual memory than the available RAM is a relatively rare occurrence.  There is little point in allocating a large minimum size pagefile, since it typically won’t be used.  However, having a relatively large maximum will avoid “out of virtual memory” conditions without dedicating a big chunk of disk space for that rare situation.

A common recommendation is to make the page file 1.5 times the size of the installed RAM.  This recommendation makes sense only for computers with small amounts of RAM (256 MB or less)...

An argument sometimes made is that the minimum pagefile has to be at least the size of the RAM so that a full memory dump can be taken when the operating system crashes.  However, this is not a very powerful argument because:...

The best way to size the pagefile is to monitor how much of the pagefile is in use and the system paging activity.  If very little of the pagefile is ever used, there is not much point in having a large minimum size.  Conversely if the pagefile is typically 80% or more used, increasing the minimum size may be advantageous.  See 2.8. Monitoring RAM and Virtual Memory usage for more information about monitoring memory and pagefile use.

至于不设 Page File 上限可能会做成碎片，这只会在 Page File + RAM 不够用的情况下发生。要是真的发生，则表示 RAM 不充足，要是不能再添加 RAM 可以加大 Page File。而即使 Page File 出现碎片，以后可以 defrag 及加大，总比程序/系统崩溃要强。

是啊，你说的对，看个人喜好了，
如果你的内存在2G以上，设置1G-2G 的页面文件是均衡的，

比如我，看浏览新闻时，通常是把20-30条新闻都打开（标签），然后再看一个关一个，
这个时间内存使用基本上已经2G多了，

内存2个G就可以直接关闭虚拟内存
设置反而关闭好

内存就是买来用的，不存在浪费不浪费，空着2G，难道才是节省吗
个人4G内存，1G做成虚拟盘，存放临时文件，IE的浏览碎片
Page File 设成0，一直没遇到因此引起的蓝屏或者崩溃

z03x10g

我2G内存，虚拟的设在D盘最小2046，最大4096

vista1G足够了XP直接512

/PAE 没有用的而且系统弄得很不稳定就是为了这个才换上的vista64不过PS CS11感觉在64位下确实飞快
