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
