I really don't know much about overclocking, I understand the things but not much else.
I have an EVGA SuperClocked 660, it has a core clock speed of 1046 right out of the box and effective memory speed of 6008. However, it only runs at 324 for the gpu and 162 for the memory. The memory should be around 1500 I believe, right? I overclocked it with EVGA Precision X, and it works but the farthest that I got it (before giving up) was around 850 for the GPU, and I don't remember the memory. HWInfo said that the GPU was only running around 549 or something. Also, when I set it to run at those speeds the drop to 324 as soon as the testing is finished. Is that normal? But, what are some tips? And how should I go about clocking it to where it should be? I don't really want it overclocked, but I'd like it to at least run how it says that it can.
