What i mean is it should be common logic right? The higher you OC your cpu and your gfx card the higher your score should be. Well i increased my OC speed from 953 to 955 hoping to beat my record. Instead i got a lower gpu score. I really hope someone could explain what factors are involved in ensuring you get the highest possible score cos it takes time to complete the bench and you want to use that time wisely. Here are my results: http://3dmark.com/3dmv/2837728 My gpu runs at 955 and 1160 yet i get a lower score in the graphics section. 83fps and 82fps. http://3dmark.com/3dmv/2836554 Here it's just slower by 2mhz running at 953 and 1160 yet i score 84 and 83. Yet in the first case somehow the cpu somehow will run faster and make up for it.
First of all, when comparing scores that have very small differences, you need to run several runs and average them - there is a margin for error that is more than 1fps on individual runs. Do 3 or 5 runs with both settings and average the scores/fps.
Second, if you overclock more, the card may heat more and start thermal throttling - forcibly reducing the clock speed temporarily to avoid thermal damage. Modern cards do this transparently and automatically and switch between throttled and normal mode very quickly depending on temperature. Could be that your card is throttling back for a few seconds each run with higher clocks -> lower score.
