标题: 求助，RAMDISK问题
各位老大，小弟我用的是华硕F8SG的本子，现在是两根2G内存条，BIOS也刷到了官方最新版，可是BIOS中根本没有memory Remap这个选项，所有现在用Ramdisk也只能使用到识别出来的3G内存。在网上了找了很多资料，可都是说先要开启memory remap才能使用整个4G的。没办法，就来求助各位大虾，第一个问题是F8SG到底能不能开启memory remap功能？第二，如果不能开启，有没有什么其它的方法能使用到整个4G内存？（前提是不换64位系统）希望高手解答一下，感激不尽！

64位XP不用，经常出问题，唉，难道就没有其它办法了？

换2003企业版

方法是有的,<认了又能怎样>
一般系统认了4G内存,也用不了多少,不如在未识别的内存创建一个虚拟盘,把系统临时文件夹移上面去,你想想内存读速度比硬盘快N倍,系统明快了。
还是这个方法合理利用内存好啊!

大哥，我就是把用不了的内存拿来创建虚拟盘的，只是现在我用RamDisk只能识别到3G内存，这样剩下的1G就用不了了，问题是我想用上那1G来做虚拟盘！

似乎ramdisk听说是主动用看不见的那一部分。

好像有这一说，还有个什么reg4G的注册表文件，问题是我根本没有在boot.ini中写上PAE，系统属性上就显示了扩展物理内存，唉，也不知道是怎么回事，就是用不上那多的1G内存

win2003 能认到4G内存
winxp 32bit 不能认到4G，只能认到3.25G（记得不是很清楚

好像要在Boot.ini 启动文件加 /PAE 参数

http://msdn.microsoft.com/en-us/library/ms791485.aspx

Windows Driver Kit: Driver Development Tools
/pae
The /pae parameter enables Physical Address Extension (PAE). This parameter directs the system to load the PAE version of the Windows kernel.

For more information about using the /pae parameter and the other parameters that affect PAE configuration, see Boot Parameters to Configure DEP and PAE.

/pae

Comments
The /pae parameter is supported only on Windows Server 2003, Windows XP, and Windows 2000. On Windows Vista and later versions of Windows, use the PAE element with the BCDEdit /set command.

PAE is an addressing strategy that uses a page-translation hierarchy to enable systems with 32-bit addressing to address more than 4 GB of physical memory. PAE also supports several advanced system and processor features, such as Data Execution Prevention (DEP; "No execute"), Non-Uniform Memory Architecture (NUMA), and hot-add memory, so it is also used on computers with less than 4 GB of memory. PAE must be supported by the processor and by the operating system.

PAE is supported beginning with the Windows 2000 operating system.

Operating system Maximum memory support with PAE
Windows 2000 Advanced Server 8 GB of physical RAM
Windows 2000 Datacenter Server 32 GB of physical RAM
Windows XP (all versions) 4 GB of physical RAM*
Windows Server 2003 (and SP1), Standard Edition 4 GB of physical RAM*
Windows Server 2003, Enterprise Edition 32 GB of physical RAM
Windows Server 2003, Datacenter Edition 64 GB of physical RAM
Windows Server 2003 SP1, Enterprise Edition 64 GB of physical RAM
Windows Server 2003 SP1, Datacenter Edition 128 GB of physical RAM

* Total physical address space is limited to 4 GB on these versions of Windows. When 4 GB of memory is installed and PAE is enabled, the amount of available memory could be less than what you would expect. For more information about memory usage, see article Q888137, "The amount of RAM reported by the System Properties dialog box and the System Information tool is less than you expect after you install Windows XP Service Pack 2" in the Microsoft Knowledge Base.

The /pae parameter is valid only on boot entries for 32-bit versions of Windows that run on computers with x86 and x64-based processors. On 32-bit versions of Windows, PAE is disabled by default. You must use the /pae boot parameter to enable PAE.

However, Windows automatically enables PAE when the computer is configured for hot-add memory devices in memory ranges beyond the 4 GB region, as defined by the Static Resource Affinity Table (SRAT). Hot-add memory supports memory devices that you can add without rebooting or turning off the computer. In this case, because PAE must be enabled when the system starts, it is enabled automatically so that the system can immediately address extended memory that is added between restarts. Hot-add memory is supported only on Windows Server 2003, Datacenter Edition; Windows Server 2003, Enterprise Edition; Windows Server 2008, Datacenter Edition; Windows Server 2008, Enterprise IA64 Edition; and on the datacenter and enterprise editions of all later versions of Windows Server. Moreover, for versions of Windows prior to Windows Server 2008, hot-add memory is supported only on computers with an ACPI BIOS, an x86 processor, and specialized hardware. For Windows Server 2008 and later versions of Windows Server, it is supported for all processor architectures.

On a computer that supports hardware-enabled Data Execution Prevention (DEP) and is running a 32-bit version of the Windows operating system that supports DEP, PAE is automatically enabled when DEP is enabled and, on all 32-bit versions of the Windows operating system, except Windows Server 2003 with SP1, PAE is disabled when you disable DEP. To enable PAE when DEP is disabled, you must enable PAE explicitly, by using /noexecute=alwaysoff /pae. For more information about DEP, see /noexecute and /execute.

PAE is required to support Cache Coherent Non-Uniform Memory Architecture (known as ccNUMA or NUMA) on computers with x86 processors, although Windows can run in non-NUMA mode on NUMA-capable computers without PAE. Even when it is required, PAE is not enabled automatically. NUMA is supported in all editions of Windows XP and Windows Vista, and in the Enterprise and Datacenter editions of Windows Server 2003.

Example
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Enterprise" /fastdetect /pae

Bootcfg command
bootcfg /raw "/pae" /A /ID 1

唉，不折腾了，为了用上4G内存换个操作系统不划算，另外楼上兄弟给的这个就是我现在用的，也认不了4G，不管怎么说，还是谢谢各位的帮助！！再次感谢！！！

和楼主一样伤过脑筋。网上滴方法-----俺这里都不灵。
后来发现：除非RamDisk能和BIOS一样在最底层接管，否则系统认多少就是多少

那你是怎么解决的啊？现在搞定没？

VSuite.Ramdisk.普通免费版
装完软件后，创建内存盘时勾上启用系统未识别的内存选项即可，有一定风险（系统崩溃），慎用

这个当时也下载了，因为现在的系统每天都要开发用，所以没敢试，呵呵，哪天闲下来了再试试。非常感谢你提供的建议

那是不可能的，32位就只能管理3.25G的内存。

RAMDISK所使用的，也仅仅只能是OS认出的部份。别说RAMDISK了，就算集显共享内存，也只能这样。
