如何知道允许的最大 RAM 内存?

如何知道允许的最大 RAM 内存?

我找到了一台旧的 HP 530 笔记本电脑,并计划用 SSD 和新 RAM 对其进行升级,以便将其交给我弟弟完成学校作业。

我执行 dmidecode 命令来了解系统规格,并得到以下输出:

据我了解,RAM 内存的最大数量是 4GB,但我不确定是否应该购买单个 4GB 内存条或两个 2GB 内存条。我应该购买哪种类型的内存(DDR2?)?

有人可以帮助我吗?

谢谢你们 :)

根据 HP 论坛和手册,我发现最大内存限制为 2GB。

有关详细信息,请阅读以下 HP 530 笔记本电脑维护和服务指南的第 1 和第 2 页。
