我怎么知道我可以给我的笔记本电脑升级多少 RAM?

我有一台 Acer (Aspire E1-431) 笔记本电脑。我想增加它的 RAM。理想情况下,我希望有 4Gb,但我不知道如何检查硬件是否支持此扩展。

答案1

检查最大 RAM 容量的另一种方法是使用 dmidecode:

sudo dmidecode -t memory

输出将会像这样:

Handle 0x000A, DMI type 16, 15 bytes
Physical Memory Array
    Location: System Board Or Motherboard
    Use: System Memory
    Error Correction Type: None
    Maximum Capacity: 2 GB    <---- look for this line
    Error Information Handle: Not Provided
    Number Of Devices: 2

...甚至更好sudo dmidecode -t memory | grep Max

答案2

一般来说,在终端(按 ctrl-alt-t 启动)中运行以下命令:

sudo dmidecode | more

并查看“物理内存阵列”,它会告诉您系统内存的最大容量和设备数量。

答案3

Accer 网站您可以通过设备序列号搜索设备,该序列号位于输出的第一部分serial: NXM8VSI0013090643D7620。在下一页上转到产品详情然后再次输入您的序列号,您将看到该笔记本电脑的规格。它显示您的最大内存为 8 GB。
