前段时间网上买了金士顿的系统指定内存（DDR3 1600 低电压版本1.35V), 8G x 2 = 16GB。顺利安装到了Mac Mini上，运行稳定快速。今天以为这么大内存用在家用的Mac Mini上实在是浪费，因而把它们转移到了ThinkPad T410S笔记本上。因而各类问题来了，首先是使用超过600MB内存时，Linux系统自动重启；而后是好好的Windows7系统没法启动。因而各类排查，最终换回原来的内存条解决问题。web
以后，仔细查看了京东上的产品说明，“适用于Sandy Bridge及以上平台”。立刻用CPU-z测试，发现ThinkPad T410S的CPU代码名为Arrandale，属于Westmere平台，是比Sandy Bridge更早出现的一个平台。因此，兼容性确定存在问题。架构
又查了一下T410s在2010年上市，早于Sandy Bridge的上市时间2011年，显然T410S是不可能采用Sandy Bridge架构的。另外，从Sandy Bridge开始，Intel i系列CPU的型号采用四位数字，如 i5 M2600，而以前采用的是三位数字，如i5 M570。ide
仍是老老实实地把8GX2超大内存条返回到了Mac Mini上，T410S只能看着眼馋了…svg
由此看来，一样是DDR3的内存条，也不必定全都通用，还要注意其适用的CPU平台。测试

P5: original Pentium microprocessors
P6: used in Pentium Pro, Pentium II, Pentium II Xeon, Pentium III, and Pentium III Xeon microprocessors.
Pentium M: updated version of Pentium III’s P6 microarchitecture designed from the ground up for mobile computing.
Enhanced Pentium M: updated, dual core version of the Pentium M microarchitecture used in Core microprocessors.
NetBurst: used in Pentium 4, Pentium D, and some Xeon microprocessors. Commonly referred to as P7 although its internal name was P68 (P7 was used for Itanium). Later revisions were the first to feature Intel’s x86-64 architecture.
