Q: recently bought a HP DV4-3126 notebook recently found that the HD 6750M card in the Windows7 experience test score is very low, only test the processor temperature and hard disk temperature with Master Lu, the rest were not measured out, CPU-Z can not read the card information, so I wonder, may I ask how to solve this problem

甲：看来，读者的高清6750m只是在PCI-E 1.1times模式工作。读者的带宽是非常有限的，所以性能不能反映在所有的pci-e.first，建议检查电源模式设置为高性能；；模式，然后进入电源选项mdash；mdash；高级设置mdash；mdash；ATI显卡的电源设置，将连接电源和电池选项设置为优化绩效如果电源模式设置正确，那么你可以尝试重新安装显卡驱动并推荐hp官方驱动和非公共驱动使用。如果上面的方法仍然不能解决问题，我们只能恢复或重新安装的系统，这样的问题是可以解决的。
