Hello, my friend gave me his old G62-b18ER laptop, I have been reinstalled its operation system to Windows 7 Pro.  after that when I installed video drivers from AMD web site I chacked video card information in GPU-Z and found that my HD5470 card memory type is DDR2, but on HP product web site saids that it mast be ddr3, also my system seen graphic card like "HD 5400 series" but not like "HD 5470", only in AIDA64 I saw correct video card name. May it be drivers problem? What drivers or other soft should I download?

It's normal for the system to give just the "series" name. No worries there.

As for the DDR 2 vs 3, that could just be a detection issue and no big deal if everything is working fine.
