Hello mates Firstly I want to be excused for my bad English . Well the problem is that when I start GPU-z firstly there is no Memory Type showed ?! Secondly the Memory clock values are NOT the same as they are showed in - http://www.notebookcheck.net/AMD-Radeon-HD-6770M.43955.0.html . The values are http://gpuz.techpowerup.com/11/09/07/cqs.png - GPU Clock Memory 800MHz and Default Clock 216 MHz. When I'm playing games (like Sacred 2 or AVP) the values for Memory clock are 216 ... . Are they not supposed to be " Memory Speed * 1600 MHz " ?? Please answer and help a noobie to understand what's wrong and that to do .
