我正在尝试将旧笔记本的 RAM 内存从 1x2Gb 升级到 1x4Gb：
2Gb（顶部）/4Gb（底部）DDR3 SO-DIMM
根据制造商的规格，这款笔记本最大支持 8Gb（2x4Gb）。
此外，如果两个插槽都已填满，则它们必须具有相同大小的模块。
但是，无论我将 4Gb 插入哪个插槽或留空，笔记本电脑都不会开机自检。
我得到的只是未知的哔声代码错误 ( -.. ---..|声音的）。
注意：我没有尝试升级到 6Gb (2Gb+4Gb)。
我确信这两块内存条都能正常工作，因为我可以在其他笔记本电脑上运行它们。
问题
- 为什么这台笔记本电脑无法使用单个 4Gb 内存条进行 POST？
- 我应该检查哪些参数才能保证 RAM 条和笔记本电脑的兼容性？
硬件规格
- 产品名称：宏碁 Aspire E1-421
- 处理器：AMD E1-1200 双核 APU @ 1.40 GHz
- 数据表
- 服务手册 | 系统内存
