内存条其实就是我们所说的运行内存 我这里废话不多 希望能给大家提供帮助
  
前言
一、查看内存条型号信息和个数
二、查看cup型号 信息 个数
总结 其他的小知识
我这边还有vSphere，ESXi 系统上查看内存条方面信息的文章 从我的博客找
  
 

 
 
前言
 
不说那么多废话 很多人网上查 关于windows如何查看内存条和cpu信息乱七八糟的 查不到具体的信息 我在这总结了一下，具体内容如下
 
 
提示：以下是本篇文章正文内容，下面案例可供参考
 
一、查看内存条型号信息和个数
 
 
 
1.首先win+r 输入cmd回车
 
 
 
 
 
2.在命令行界面输入wmic进入命令行系统管理执行脚本界面； 依次输入命令memorychip进行查看内存型号，可以看出，有一条内存，如果是两条信息就是两条内存 内存条型号也可以看出
 
 
 
 
 
 
3.查看内存条大小 方法有很多 右击电脑属性 和 在【运行】窗口中输入dxding命令诊断工具 都可查看 还有在【运行】窗口中输入【msinfo32】都可查看
 
 

 
 
 
至于查内存条的厂家信息 你查到他的型号 还查不出他的厂家吗？
 
二、查看cup型号 信息 个数
 
 
 
1.通过cpu get *可以查看cpu的具体情况(注意空格)，拖动滚动条找到numberofcores核心数和numberoflogicalprocessors线程数两列。
 
 
 
 
 
2.看cpu个数 在cmd命令中输入“systeminfo”，以下信息表示物理CPU有一个
 
 
 
 
 
或者在任务管理器里 查看cpu 有几个框就有几个cpu 可以看出 一个cpu 8核 内核数为2，即每个CPU有4个可供计算的芯片
 
 
 
 
 
3.cpu型号 电脑右击属性就可看出
 
 
 
 
总结 其他的小知识

如何在windows系统自带命令查看硬件信息，怎样dos命令查看硬盘和内存/CPU信息？最直接的是：开始→运行→CMD打开命令提示符，在该窗口下输入systeminfo执行，即可看到几乎所有想知道的系统信息，甚至包括机器上已安装的网卡及其IP。
问题描述: 如何从系统中 查看主板上内存条的数量。
最佳答案: 在cmd命令下 输入：wmic memorychip list brief 或者 wmic MEMPHYSICAL list brief 就会看到内存条的数量

rem 查看cpu
wmic cpu list brief
rem 查看物理内存
wmic memphysical list brief
rem 查看逻辑内存
wmic memlogical list brief
rem 查看缓存内存
wmic memcache list brief
rem 查看虚拟内存
wmic pagefile list brief
rem 查看网卡
wmic nic list brief
rem 查看网络协议
wmic netprotocal list brief

如何在windows系统自带命令查看硬件信息？

对于在windows下查看系统信息大家一定不陌生了，我现在说几个最常用的方法，对命令感兴趣的朋友看看，（给菜鸟看的，老手就不要笑话我了，大家都是从那个时候过来的，^_^）。

一．图新Shell下：
1.    最直观的：（在运行里面输入CMD，以下命令都是在CMD下输入的：）
输入 sysdm.cpl, 系统属性.
2.    输入dxdiag
3.输入 start msinfo32，winmsd系统信息
3.    输入 devmgmt.msc，设备管理：
4.    输入 taskmgr （或按Ctrl+Alt+Esc） 在性能选项卡看物理内存和pagefile
5.    输入 winver 也可以查看内存大小 

怎样dos命令（cmd命令）查看硬盘和内存/CPU信息？

1.查看磁盘信息：freedisk 可以查看每一个盘的剩余空间

wmic diskdrive

可以看出来牌子和大小.

Wmic logicaldisk

可以看到有几个盘，每一个盘的文件系统和剩余空间

wmic volume

每个盘的剩余空间量，其实上一个命令也可以查看的

fsutil volume diskfree c:

这个命令查看每一个卷的容量信息是很方便

2.CPU信息

wmic cpu

上面显示的有位宽，最大始终频率， 生产厂商，二级缓存等信息

3.内存信息

    wmic memorychip

可以显示出来三条内存，两条256，一条1G的，速度400MHz

4.BIOS信息

    wmic bios

主板型号

BIOS 版本

从任务列表中找到需要的进程

tasklist | findstr /s /i e.*
tasklist | findstr /s /i "python"

切换目录
cd /d D:/
dir
start D盘中的文件夹即可打开文件夹
tasklist/svc 就可以看到计算机当前正在运行程序

前言：我电脑内存不够用，计划扩充内存。
 
方法：sudo dmidecode -t memory
 
Tips：使用的内存条型号建议一致，这样兼容性会好一些。
 
介绍：第一块介绍的是主板Array情况，单个接口最大64G，总共4个接口；第二块介绍的是Memory device的情况，我的电脑上的8G内存条插在Handle 0x0048，dd4类型，8G大小，制造商金士顿等等，无内存条的部分显示为Unknown。
 
问题：暂时无法通过命令查看内存插口类型是ddr3还是ddr4，期待同行提示。
