What is effective memory clock and why is GPU Z only showing 1552 Also question about boost clock!

post #1 of 3
Thread Starter 
My gtx 670 FTW cards say they have an effective memory clock of 6208 MHZ yet in GPU Z it shows only 1552 memory.. is there a reason there is a discrepancy?

Also I was reading that boost clock will dynamically increase the GPU clock speed even past the set rating of 1084, is this true? Some people say there cards automatically go beyond that if they need too.

As it is DDR5 memory you need to take the number x 4 - 1552 x 4 = 6208.

The GPU will dynamically boost the speed depending on a lot of different scenarios.
