Why is my iMac not starting up after I installed Transcend memory on it? 分类 : 设定安装与操作使用 Please be noticed that it takes about 1 to 2 minutes for the iMac's screen to start displaying things properly the first time it is turned on after memory installation. It should work fine afterwards. Is the answer helpful? 相关信息 DDR3 和 DDR2 可否各自向下兼容于DDR2 及DDR？ Will a faster frequency memory of the same type run at slower frequency?
