在linux系统中，查看内存条个数，及每根内存的大小，可以使用dmidecode命令。
如下：
#dmidecode | grep -A16 "Memory Device$"
输出结果：
Memory Device #存储设备 Array Handle: 0x1000 #阵列处理 Error Information Handle: Not Provided #错误信息的处理：不提供 Total Width: 72 bits #总宽度： 72位 Data Width: 64 bits #数据宽度： 64位 Size: 1024 MB #大小 Form Factor: Set: 1 Locator: DIMM1 Bank Locator: Not Specified Type: Type Detail: Synchronous #输入详细信息：同步 Speed: 667 MHz (1.5 ns) #速度： 667兆赫（ 1.5纳秒） Manufacturer: 80AD7FB380AD #制造商 Serial Number: 42600700 #序号 Asset Tag: 010910 Part Number: HYMP112F72CP8D3-Y5 -- //by www.jb51.net Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: 1024 MB Form Factor: Set: 1 Locator: DIMM2 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: 667 MHz (1.5 ns) Manufacturer: 80AD7FB380AD Serial Number: 42600213 Asset Tag: 010910 Part Number: HYMP112F72CP8D3-Y5 -- Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: 1024 MB Form Factor: Set: 2 Locator: DIMM3 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: 667 MHz (1.5 ns) Manufacturer: 855185518551 Serial Number: 0503BE1A Asset Tag: 4C0838 Part Number: 72T128401EFA3SC2 -- Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: 1024 MB Form Factor: Set: 2 Locator: DIMM4 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: 667 MHz (1.5 ns) Manufacturer: 855185518551 Serial Number: 0503BF1F Asset Tag: 4C0838 Part Number: 72T128401EFA3SC2 -- Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: No Module Installed Form Factor: Set: 3 Locator: DIMM5 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: Unknown Manufacturer: Serial Number: Asset Tag: Part Number: -- Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: No Module Installed Form Factor: Set: 3 Locator: DIMM6 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: Unknown Manufacturer: Serial Number: Asset Tag: Part Number: -- Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: No Module Installed Form Factor: Set: 4 Locator: DIMM7 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: Unknown Manufacturer: Serial Number: Asset Tag: Part Number: --//by www.jb51.net Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: No Module Installed Form Factor: Set: 4 Locator: DIMM8 Bank Locator: Not Specified Type: Type Detail: Synchronous Speed: Unknown Manufacturer: Serial Number: Asset Tag: Part Number:
然后，用free命令查看当前内存的使用情况：
# free -m total used free shared buffers cached Mem: 4054 2963 1090 0 144 1272 -/+ buffers/cache: 1547 2506 Swap: 4094 0 4094
