Is there anyway to verify the speed that these tools are setting? 3DMark is reporting the new speed (1050mhz) on the report when I run it.
muhhhahaha, yes there is a way to verify your speed. If you score goes up in 3dmark/01/03/05 everytime you increase the core.
I just tried this, I lowered the RAM to 275 to really make it the bottleneck and then I ran 3dmark01 at 300 core, 350, 400 and 450 and the score went up each time. Thus, I have no doubt that if you ram is running ~400 then if you put the core to 500 and then 550 and up that you would have some positive scaling in the scores, but you didn't after 500 or so when you tested. That means your core was not set at those higher speeds.
