为您找到与win8最大支持内存相关的共200个结果:
买了台电脑,朋友都说可以换内存,内存大电脑运行快,但是自己是电脑小白,不知道怎么查看电脑内存,如果换内存的话应该换多大的呢?怎么才能查询电脑最大支持的内存是多少?下面读文网小编就为大家介绍一下查看自己电脑最大内存的方法,记住一个道理,硬件+操作系统=决定支持的最大内存。
1、打开“开始”菜单,点击“运行”按钮
2、在弹出来的窗口输入“CMD”,然后确定或者按下回车键。
3、在命令窗口输入“wmic memphysical get maxcapacity”然后敲下回车键。
4、然后电脑会给出一串以千字节为单位的数字。我们再把这串数字换算成我们常见的GB单位的。
换算方法是:“得出来的数字/(除以)1024/(除以)1024“
如图:我的电脑得到的是16777216K字节这串数字,那我除以1024再除以1024,就等于16GB了。也就是说,我的这台电脑的硬件,跟我装的这个系统,支持的最大容量的内存是16GB。
1、操作系统不同,主板不同,那么它们所支持最大内存容量也是不同的
2、Win 32位的系统,最高是支持3.25G左右的内存,无论你的主板最高支持多少,但32位系统最高只能支持3.25G左右内存
3、如果你装的内存超过4G或刚好4G,请装64位的操作系统,以获得更大的内存支持,加快个人PC的处理速度

怎么查看电脑主板最大支持多少内存?每个电脑都有自己的适配内存,就是每个电脑能支持多大的内存,那么我们的电脑最大支持多少内存呢?下面读文网小编就带大家一起来看看计算方法吧。
很多电脑,内存不够用,但应速度慢;还有一些就是买了很大的内存条,但是还是反应慢;这是为什么呢?我今天明白了,原来每个电脑都有自己的适配内存,就是每个电脑能支持多大的内存,其实已经告诉我们了。
1、如何才能查看自己的电脑到底能够适配多大内存呢?废话不多说了,直接上步骤,通过一步步操作来进行操作运行吧。
2、使用快捷键:win+R打开命令窗口。或者点击开始-运行打开命令窗口。
3、找到光标所在位置。
4、在光标处输入wmic memphysical get maxcapacity命令,每个单词中间加一个空格。
5、输入完成之后按回车键(enter键)。
6、在输入命令之后出现一组数字,输入计算器中。
7、将这一组数字除以1024.
8、得出的数字再除以1024.得出的就是最大支持的内存了。
注意事项:命令符号一定要输入正确,还有要计算正确。

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

为什么Win8系统4G内存,在计算机属性中只显示2.99G可用,还有1G内存跑哪去了?针对此问题,不少网友都知道,是由于用户安装32位Win8系统所致,之后网友又提到“Win8 32位支持多大内存?”,对于这个问题,知道准确答案的并不多,下面读文网小编就为大家介绍一下具体的知识内容吧,欢迎大家参考和学习。
很多朋友度知道32位Win8系统,无法完全使用4G内存,通常可使用的内存只有3G左右,不同32位Win8电脑可能可使用的内存也有所不同,比如我们最常见的内存容量有2.46GB,3GB,3.25GB,3.5GB等。
其实不管是XP、Win7还是Win8系统,理论上均是32位系统最大支持4G内存,但实际系统识别不会到4G,我们看到的最大有3.75G,最小2.9G左右,多半是笔记本,而一般电脑可使用内存通常在3.25G或者3.5G左右,这个和主板、硬盘、光驱、声卡,显卡,无线网卡等硬件设备有关,因此不同电脑,其真实可用内存也会有一些小小的不同。
编后语:Win8 32位理论上最大支持4G内存,但实际电脑中通常仅显示3G左右,见过最大可用内存为3.75G,如果想要全部显示4G内存可用,建议您安装64位操作系统,另外还有一些破解软件,可以帮助我们让32位系统显示4G可用内存,不过此类破解工具,可能会导致电脑蓝屏,因此不建议推荐使用。

Samsung Galaxy S4是韩国三星集团旗下生产商三星电子,于2013年推出的新一代旗舰型智能手机,是Samsung Galaxy S系列的第四代。三星公司于2013年3月14日,美国东部时间晚上七时,在纽约时代广场举办的Samsung Unpacked 2013上正式发布。下面就由读文网小编为大家整理的相关信息,供大家参考!
三星Galaxy S4的RAM为2GB,提供了16GB、32GB、64GB的可选存储空间,支持microSD扩展。
三星Galaxy S4机身尺寸为136.6mm×69.8mm×7.9mm,重量为130克,外观上与此前曝光的真机照完全一致,机身材质为聚碳酸酯,有黑白两色可选。
三星Galaxy S4采用5英寸全高清Super AMOLED显示屏,像素密度441ppi,搭载1.6GHz三星Exynos 5八核处理器(国际版)或1.9GHz高通Snapdragon S4 Pro四核处理器(美国版),2GB内存,16/32/64GB存储空间,支持microSD扩展,1300万像素主摄像头,200万像素前置摄像头,8个传感器,包括红外、手势、温度和湿度传感器等,拥有2600mAh电池,运行Android4.2.2系统。
三星Galaxy S4不仅拥有高水准的硬件配置,在功能上也延续了三星GALAXY S3的人性化人机交互体验。
Galaxy S4外观设计与三星Galaxy S3相比改变很少,
三星s4手机壳手机外壳依然使用了与S3一样的hyperglaz涂层材料。总的来说,在我们的实机体验中,手机的握持感相比GS3反而更好。握在手里的感觉反而比拥有4.7英寸的HTC One更佳。三星也向竞争对手证明5英寸的屏幕并不意味着就将带来握持手感的下降。
当然想必机友们都非常期待Exynos 5 Octa八核版本的跑分,毕竟该款处理器配备了标准的ARM Cortex-15架构,而骁龙600使用的Krait内核,介于A9与A15架构之间。除此之外双四核版Exynos处理器的GPU使用了PowerVR SGX 544MP3,性能比骁龙600的Adreno 320较好,性能较上一代有明显提升。

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

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
# 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。
sudo dmidecode -t 17

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

内存大电脑运行快,但是自己是电脑小白,不知道怎么查看电脑内存,如果换内存的话应该换多大的呢?怎么查询电脑最大支持的内存是多少?下面分享查看自己电脑最大内存的方法。
1、打开“开始”菜单,点击“运行”按钮
2、在弹出来的窗口输入“CMD”,然后确定或者按下回车键。
3、在命令窗口输入“wmic memphysical get maxcapacity”然后敲下回车键。
4、然后电脑会给出一串以千字节为单位的数字。我们再把这串数字换算成我们常见的GB单位的。
换算方法是:“得出来的数字/(除以)1024/(除以)1024“
如图:我的电脑得到的是16777216K字节这串数字,那我除以1024再除以1024,就等于16GB了。也就是说,我的这台电脑的硬件,跟我装的这个系统,支持的最大容量的内存是16GB。
注意事项:
1、操作系统不同,主板不同,那么它们所支持最大内存容量也是不同的
2、Win 32位的系统,最高是支持3.25G左右的内存,无论你的主板最高支持多少,但32位系统最高只能支持3.25G左右内存
3、如果你装的内存超过4G或刚好4G,请装64位的操作系统,以获得更大的内存支持,加快个人PC的处理速度

内存是计算机中重要的部件之一,它是与CPU进行沟通的桥梁。那么,你们知道在W8系统中 32位的支持多少内存吗?下面是读文网小编带来的关于win8 32位支持多少内存的内容,欢迎阅读!
够的
CPU方面:双核主频2.0GHz 以上
内存方面:2GB或更高DDR2 内存以上
显卡方面:集成显卡(64M显存)或独立显卡以上
硬盘方面:20G可用磁盘空间以上
win8的配置要求,如果不玩什么大型烧显卡类型和设计类型的话,够用的

你们知道64位系统的W8支持多大的内存吗?下面是读文网小编带来的关于win8 64位支持多大内存的内容,欢迎阅读!
首先了解一下win8的最低配置如图:
win8:
CPU:2GHz双核处理器(支持PAE、NX、SSE2);
内存:2GB(32位)/4G(64位);
硬盘:大于等于24GB(32位)/大于等于30GB(64位)
显卡:支持DirectX 10/Shader Model 4.0以上级别的独立显卡 显卡支持DirectX 9就可以开启Windows Aero特效;
显示器:1366*768分辨率
也就是说,如果要安装32位的win8,内存最好2G以上,如果要安装64位win8,内存至少4G以上才能让系统比较顺畅得运行。

想知道XP系统中内存最多是支持多少呢,下面是读文网小编带来的关于winxp最大支持多少内存的内容,欢迎阅读!
32位系统最大用4G内存,他的寻址空间就是2的32次方个字节,就是4G
Windows认为这么大的内存应该分开用,于是就把2G分给于系统,2G分给程序。
所以有上面的提示也是正常的。
说一下楼上的几个,现在能支持4G的内存的主板多的是。
只是系统不支持,本人安过多种系统,就此也说一下。
XP 32位,只能认到3.25G的内存,但在windows下用软件测试却能测出主板支持4G内存,只是XP不挣气。
XP 64位,只能认到3.75G的内存,同样软件也可以测出主板支持4G。
Vista 32位,3.25G.不好意思,这个系统也不怎么的。
Vista Sp1 32位,本人安这个的时候,狂喜一阵,他能显示出4G的内存。
但经过软件测试,VISTA SP1 32位只是显示出来了,可用内存却还是3.25G。
VISTA 64位,这个是真正能用到4G内存,不只是显示。
Win 7 32位英文测试版,这个也能显示4G内存,但和VISTA SP1一样,光显示,实际可用内存就是3.25G
Win 7 64位英文测试版,和VISTA 64一样,这个是真正能用到4G内存,不只是显示。

想知道电脑最大支持多少内存吗,下面是读文网小编带来的关于xp最大识别多少内存的内容,欢迎阅读!
32位的XP系统,其逻辑地址编码采用的地址位数是32位的,那么操作系统所提供的逻辑地址寻址范围是4GB。 而在intel x86架构下,采用的是内存映射技术(Memory-Mapped I/O, MMIO),也就说将4GB逻辑地址中一部分要划分出来与BIOS ROM、CPU寄存器、I/O设备这些部件的物理地址进行映射,那么逻辑地址中能够与内存条的物理地址进行映射的空间肯定没有4GB。 一般是3.2G左右。
64位的XP系统,其逻辑地址编码采用的地址位数是40位,能够最大支持1T的逻辑地址空间。考虑一种情况,假如CPU是64位的,地址总线位数是40位,操作系统也是64位的,逻辑地址编码采用的地址位数也是40位,内存条大小是64GB。
内存的大小,受主板芯片组影响。 系统 支持,但主板不支持也没得用,以主板为准。
