Good day sirs, I have a question on my Laptop's Gpu Memory speed Here is MY QUESTION.
- I saw Acer and Asus with similar gpu (GDDR3)has their "Memory Data Rate: 2002 MHz"
- While mine and other review has ours at "Memory Data Rate: 1800 MHz" What is the reason why only 1800 instead of 2002? When gaming it shows 900 instead of 1001 MHz.
- Memory bandwith is only 28.80 instead of 32.03 GB/s.

Well thanks for the answer all laptops brand mention both has GDDR3 including mine what bothers me is that frequency being lower on what it should be. I wonder why makes me sad... If I increase it to 1000 MHz will it affect my Gpu's lifespan or it will be the same as Acer and Asus???
