你想了解Linux基础:如何找出你的系统所支持的最大内存吗,下面,小编立即为您献上教程。
大多数情况下你可以从BIOS、产品目录或者干脆手动找出你的系统所持的最大内存。这里,我们介绍一种简单有用的技巧——使用dmidecode来找出系统支持的最大内存,这样你就无需打开机箱或者参照BIOS和产品目录了。
什么是 dmidecode?
就像你可能知道的一样, dmidecode是一个将计算机DMI(又名SMBIOS)表的内容转换为可读格式的工具。这个表包含了系统硬件组件的介绍以及其他一些如序列号和IOS版本等有用的信息。使用dmidecode你能够获取此项信息,而无需去探测真实的硬件。
找出你的系统所支持的最大内存
请确定你已经在系统中安装了dmidecode,我觉得你的操作系统应该已经自动安装过了,不过并不非常确定。
在基于Deb的系统中安装
1sudo apt-get install dmidecode
在基于RPM的系统中安装
1sudo yum install dmidecode
在SUSE/openSUSE中安装
1sudo zypper in dmidecode
好了,我们已经安装了dmidecode,接下来让我们找出支持的最大内存。输入以下命令:
1sudo dmidecode -t 16
输出样本
11# dmidecode 2.12
SMBIOS 2.6 present.

就像你看到的,我的系统支持最大内存到16G,并且有两个内存插槽,简单吧?
接下来,让我们找出现在已经安装的内存的详细信息。

大多数情况下你可以从BIOS、产品目录或者干脆手动找出你的系统所持的最大内存。这里,我们介绍一种简单有用的技巧——使用dmidecode来找出系统支持的最大内存,这样你就无需打开机箱或者参照BIOS和产品目录了。让我们一起去看看。
什么是 dmidecode?
就像你可能知道的一样, dmidecode是一个将计算机DMI(又名SMBIOS)表的内容转换为可读格式的工具。这个表包含了系统硬件组件的介绍以及其他一些如序列号和IOS版本等有用的信息。使用dmidecode你能够获取此项信息,而无需去探测真实的硬件。
找出你的系统所支持的最大内存
请确定你已经在系统中安装了dmidecode,我觉得你的操作系统应该已经自动安装过了,不过并不非常确定。
在基于Deb的系统中安装
sudo apt-get install dmidecode
在基于RPM的系统中安装
sudo yum install dmidecode
在SUSE/openSUSE中安装
sudo zypper in dmidecode
好了,我们已经安装了dmidecode,接下来让我们找出支持的最大内存。输入以下命令:
sudo dmidecode -t 16
输出样本

就像上边输出的一样,我在插槽1里边安装了一个内存条。内存大小为4G,类型为DDR3,速度为1067 MHz。
同样的,我们可以通过下边命令得到完整的内存信息。
sudo dmidecode -t memory
sudo dmidecode -t memory | less
sudo dmidecode -t memory | more

今天读文网小编要给大家说说如何让你的WIN7 32位系统做到支持128G内存的方法!如果对此感兴趣的朋友,可以跟着读文网小编一起往下看吧!
打开软件后,您看到的界面可能跟翔飞的不一样,这个没有关系的,只是翔飞的电脑已经解除了,所以有些显示会不一样,只要按照相关说明一步一步操作即可。选择用管理员身份运行ReadyFor4GB.exe,点应用,回车退出。
同样用管理员身份运行AddBootMenu.cmd,弹出命令对话框后,输入“y”,敲回车键,
添加启动项成功后,再敲回车退出
3重启电脑,在出现开机菜单时,选择 "Windows 7 x86 [ 128GB with ntkr128g.exe ]"
进入系统即可,至此大功告成。
总结
以上就是读文网小编为大家提供的WIN7操作系统做到支持128G内存的方法

想必大家都知道了,Windows XP/Win7/Win8/Win10系统除了有旗舰版、专业版、家庭版的版本区分之外,还有32位和64位的区别。那么区别在哪呢?其中之一就是系统支持的最大内存。下面读文网小编就为大家了解一下Windows系统32位/64位系统支持多大内存吧,欢迎大家参考和学习。
内存(RAM,也就是您的系统的寻址总空间)=内存条(物理内存,您的内存条是4GB的)+bios内存+缓存+显存+...,32位的电脑的寻址空间是2的32次方,也就是4G,系统将这4GB的地址分配给内存条,缓存,显存,硬件等。
系统分配寻址空间时是有优先级的, bios的内存,cpu的缓存,各个硬件的内存,显卡的显存等,他们的优先级比物理内存(也就是内存条)高,所以系统先将寻址空间分配给bios的内存、cpu的缓存、各个硬件的内存和显卡的显存,最后才将剩余的寻址空间分配给内存条。比如您的显卡有500MB,那么可以分配的内存也就只剩下4GB-0.5GB=3.5GB了。
相当于一条街上有1000户居民,但是门牌号码确实只有800个,于是还有200户居民没能获得门牌号码,但是这200户居民并未消失。
如果在32位电脑上装上4G内存条依照优先级关系,你只能使用3G多的的内存条空间,因为前面的几百MB空间是给了各个硬件(包括显存),4GB的内存条只有其中的3.31GB获得了寻址空间,此时您只可以看到获得了寻址空间的那一部分内存条(见下图.)
如果是2G的内存条,因为电脑本身寻址能里是4G,前面几百MB给了硬件,依旧剩余3G多的寻址空间, 2G的内存条可以完全获得2G的寻址空间,您也就能看到2G的内存条了

Windows 7是微软公司推出的电脑操作系统,供个人、家庭及商业使用,一般安装于笔记本电脑、平板电脑、多媒体中心等。微软首席运行官史蒂夫·鲍尔默曾经在2008年10月说过,Windows 7是Windows Vista的“改良版”。Windows 7于2009年7月22日发放给组装机生产商,零售版于2009年10月23日在中国大陆及台湾发布,香港于翌日发布。2011年10月StatCounter调查数据显示,Windows 7已售出4.5亿套,以40.17%市占率超越Windows XP的38.72%。下面就由读文网小编为大家整理的相关信息,供大家参考!
希望通过这两者的对比可以更直观的看出其中的差别
32位64位区别:
区别一,设计初衷不同。64位操作系统的设计初衷是:满足机械设计和分析、三维动画、视频编辑和创作,以及科学计算和高性能计算应用程序等领域中需要大量内存和浮点性能的客户需求。换句简明的话说就是:它们是高科技人员使用本行业特殊软件的运行平台。而32位操作系统是为普通用户设计的。
区别二,要求配置不同。64位操作系统只能安装在64位电脑上(CPU必须是64位的)。同时需要安装64位常用软件以发挥64位(x64)的最佳性能。32位操作系统则可以安装在32位(32位CPU)或64位(64位CPU)电脑上。当然,32位操作系统安装在64位电脑上,其硬件恰似“大马拉小车”:64位效能就会大打折扣。
区别三,运算速度不同。64位CPU GPRs(General-Purpose Registers,通用寄存器)的数据宽度为64位,64位指令集可以运行64位数据指令,也就是说处理器一次可提取64位数据(只要两个指令,一次提取8个字节的数据),比32位(需要四个指令,一次提取4个字节的数据)提高了一倍,理论上性能会相应提升1倍。
区别四,寻址能力不同。64位处理器的优势还体现在系统对内存的控制上。由于地址使用的是特殊的整数,因此一个ALU(算术逻辑运算器)和寄存器可以处理更大的整数,也就是更大的地址。比如,Windows Vista x64 Edition支持多达128 GB的内存和多达16 TB的虚拟内存,而32位CPU和操作系统最大只可支持4G内存。
区别五,软件普及不同。目前,64位常用软件比32位常用软件,要少得多的多。道理很简单:使用64位操作系统的用户相对较少。因此,软件开发商必须考虑“投入产出比”,将有限资金投入到更多使用群体的软件之中。这也是为什么64位软件价格相对昂贵的重要原因(将成本摊入较少的发售之中)。
关于内存,xp和win7 的32位支持最大4G,但是由于32位最大寻址为4G,而系统其他部分也需要内存地址,所以32位下只能看到3.2~3.5G。用win7 64位最大可支持到192G内存,但是有的主板只能支持8G或16G内存。
DDR2和DDR3差异在于电压、内存频率,你既然再用DDR2,主板应该不支持DDR3.

经常使用U盘的用户都知道,为了保证U盘的数据安全,通常情况下将U盘连接电脑后,在不需要使用U盘时,我们会使用“安全删除设备”选项来让U盘安全退出后,再拔下U盘,当这样的操作对经常使用U盘的用户来说,又显得非常的麻烦。那么你知道win7系统怎么让U盘支持直接拔插吗?下面是读文网小编整理的一些关于win7系统让U盘支持直接拔插的相关资料,供你参考。
第一步:我们需要通过组合键“Win+R”打开运行窗口,并输入“devmgmt.msc”按回车键或确定。
第二步:我们这是就能看到设备管理器窗口了,在该窗口中我们找到“磁盘驱动器”并展开,这是我们就能够看到U盘驱动程序了,(如图),并双击打开。
第三步:在打开的U盘属性设置中,我们将窗口切换到策略,然后勾选快速“快速删除(默认)”选项卡,然后点击保存!

当我们在使用电脑的时候,有时候会感觉打开的文件很少,却依然出现电脑反应迟钝或者经常卡顿的现象,一般来说出现此情况,就是电脑内存不足造成的,那么你知道win7系统电脑怎么查看内存大小吗?下面是读文网小编整理的一些关于win7系统电脑查看内存大小的资料,供你参考。
1、返回到桌面界面,找到计算机图标,然后右键点击,选择属性,就会出现如下图中所示的界面,这里的安装内存就是想要查询的物理内存的大小值。
2、接下来,还是在这个窗口,点击左侧菜单中的高级系统设置,然后在弹出来的系统属性窗口中切换到高级这一栏;
3、然后点击性能后面的设置按钮,在出现窗口中的最后一项,便是电脑的虚拟内存了,一般来说,虚拟内存是可以设置的。

很多用户都觉得32位Win7和Vista不支持4GB内存,只有64位的系统才会支持,其实不然,那么32位Win7怎么样支持4GB DDR3内存呢?下面读文网小编就为大家带来了32位Win7支持4GB DDR3内存的方法。
4GB DDR3内存一定需要64位系统么?
其实不足4GB内存的原因就在32位X86架构。32位X86架构是指个人电脑的地址总线是32位的,CPU、内存控制器、操作系统都是按32位地址总线设计。32位地址总线可以支持的内存地址代码是4096MB。这4GB个地址码正好可以分配给4GB内存。但是其它寄存器都需要系统分配给它们地址代码,所以总容量为4GB的内存就有一部分内存分配不到地址代码而不能使用。
让32位的VISTA/Win7支持4GB DDR3内存
其实,Vista/Win7自身完全支持超过4GB大内存,只是微软不让使用而已。但其实在Win7上可以通过程序破解Windows PAE内核文件ntkrnlpa.exe,绕过Zw Query License Value API函数的许可限制,让32位的VISTA/Win7支持超过4GB物理内存,下面笔者就教您如何破解4GB内存之谜。
首先,我们需要下载一款名叫Readyfor 4GB的软件,用户可以在搜索工具上搜索,下载地址有很多。
下载解压后,先运行Readyfor 4GB,当程序打开后,依次点击检查和应用选项,此时程序会告诉你所用系统能够支持最大内存容量和当前内存容量。下面的图片是笔者已经破解后所示,最大允许4GB内存。
然后以管理员身份运行压缩包里面的AddBootMenu程序,当弹出对话框时,输入Y回车即可,此时系统提示破解操作成功完成。
第三步依次选择我的电脑右键→属性→高级系统设置→启动和故障恢复→设置→选择那个破解的启动系统就可以,如下图。
最后重新启动计算机,在选择我的电脑属性后,内存被识别成4GB容量,如下图所示。
32位/64位4GB Win7带宽测试
下面我们就来看看破解后的4GB容量内存性能和64位Win7下4GB容量内存的性能差别有多大。
SiSoftware Sandra2009是一套功能强大的系统分析评测工具,拥有超过30种以上的测试项目,主要包括有 CPU、Drives、CD-ROM/DVD、Memory、SCSI、APM/ACPI、鼠标、键盘、网络、主板、打印机等。全面支持当前各种 VIA、ALI 芯片组和 Pentium 4、AMD DDR平台。除了具有强大的功能外,使用也很方便,易于上手。

从测试中看出,虽然64位Windows7可以完美支持4GB容量内存,但是成绩和32位Windows7并没有多大变化,可见没有良好64位软件的支持,根本无法发挥64位操作系统的性能。

每次打开IE浏览器,窗口都会比较小,非常不方便浏览网页,不得不去点击最大化按钮让窗口变大以方便浏览,非常麻烦,那么你知道win7系统打开网页后窗口不是最大化怎么办吗?下面是读文网小编整理的一些关于win7系统打开网页后窗口不是最大化的相关资料,供你参考。
双击IE打开浏览器,此时任务栏上一出现了ie的图标;
右击IE图标,点击“将此程序锁定到任务栏”如下图所示。这样就把IE浏览器加在了任务栏里。
1、当我们把IE浏览器加到快速启动栏后,可以在这设置了,步骤如下:首先右击ie图标;
2、右击“internet explorer”点属性;
3、点击属性出现下图所示对话框;
4、如上图所示,点击小黑三角,再出现的选项中选择“最大化”。

内存作为运行速度的保证,在一般情况下,当然是越大越好。但是Win7如何查看主板支持多少G内存呢?今天读文网小编就来告诉用户们怎么操作才能知道自己电脑内存最大支持多少G内存的方法。
1、按下WIN+R然后输入 CMD 回车;
2、打开命令提示符后 输入命令:wmic memphysical get maxcapacity 后回车;
3、这时我们会得到一个数据“33554432”,打开Win7系统的计算器 把这个数字除以1024 得到的数字就是你的Win7系统电脑所最大能支持的内存大小了!
4、得到数值 32768 相当于 32GB 内存,以这样的方式计算后就知道电脑最大支持32G最大内存。
关于查看Win7系统电脑主板支持多少G内存的操作方法就介绍完了,如果有兴趣的用户不妨测测自己的电脑支持多大的内存,希望以上的方法对大家有所帮助。
