关于/3GB

我的主板是华硕A8N-SLI SE，操作系统是XP sp2，装上4G内存，开机时可以认出4G内存，但是进入系统之后只认3G内存，请问有无办法解决，请指教，谢谢!

　　答：4G内存进入系统之后只能认出3G是很正常的，由于32位的系统平台的寻址能力上限为4GB，而且4GB的最后1GB地址空间基本上都被显卡等设备所占据了，所以系统实际上无法访问3G~4G地址段的物理内存。具体到Windows XP 32Bit，它最多只能认出3.5GB的内存，而且单个进程最多只能使用2GB的空间。即使是32位版的Windows vista也无法临驾于这个寻址的限制，最多也只能认出3.5GB。如果已经买了4GB的内存怎么办呢？您可以玩一下虚拟硬盘RamDisk，从内存中开辟一个空间当作硬盘使用速度非常快，而且用于BT下载的交换空间可以保护硬盘——内存是不怕重复读写的；二是安装64位版的Windows XP或者Vista，尽管软件非常缺乏，但是可以把4GB内存全部利用起来。建议非专业用户的内存最好不要超过2GB，否则多了也是浪费

推荐用XP2 ，为了这个，微软为SP1打了几个补丁，你可以看看

楼主真不愧为版主，太厚道了

lifangqi

非常感谢北极熊甲老师为我们作的贡献  我也是一个电磁场分析的初学者  有很多问题想向北极熊甲老师请教  就是不知道该怎么联系您 我的qq号 260336944

love850818

正在学习电机内的电磁场分析...谢谢楼主的书

xujiazhu

请教版主，如果我画出电机内气隙磁密，我如何对其进行傅立叶分解呢？我想知道其基波磁密和各次谐波

whosru

谢谢楼主，花了几天时间终于把这个帖子看完了，学到不少

yinzhen12

:lol :lol :lol :lol 好版主！

shihaiou

为什么要耦合外面屏蔽层的volt 自由度呢？耦合与否对其的power loss没有影响啊？

hy1966

已经是NTFS格式了，但是生成的文件（结果文件等）依然太大，怎么办压缩？分割？
北极熊甲 发表于 2007-10-23 15:31

电磁场分析这个命令不能用吗？

/CONFIG,FSPLIT,500，后面的数字单位Mword，1Mword=4MB

zacard_00

楼主太好了！
现在电磁学问题多多，好好看看你的帖子

zhjxie

I'm hungry now,be here this afternoon
thanks
