core/mem clock vs GPU core/mem clock

post #1 of 3
Thread Starter 
So i downloaded GPU-Z today and looked at my HD 6570's core and memory clock which was 650/900 mhz as it should be and then when i changed the tab to sensors, it showed that my GPU core clock was 100 mhz and GPU memory clock to be 150 mhz which are quite low...so i just want to ask what these two means...and why are they so low

It's displaying the card's current idle (or if you want to call it 2D) clocks--not what they would be under load conditions. Graphics cards cut their clocks when idle to conserve power and reduce heat output.

Also another question i would ask is that, some of the games such as MAFIA II run really smoothly but some older games like age of empires 3 lags sometimes...is that because of lack of ram or cpu?
