I have HP Pavilion G6 2004tx
OS: Windows 7 HB x64.
CPU: i5 2nd Gen.
RAM: 8GB DDR3 (4 + 4 newly added )
GPU: 2GB DDR3 - AMD Radeon HD 7670M
After adding 4 GB Transcend (1333 MHz) RAM in laptop, I can see only 1780mb graphics memory available, Previously it was showing more than 3000mb.
Why this is happening? What should I do to get graphics memory back?
