I was trying to overclock my asus dc2 670 so first i ran heaven without any changes and my core clock oscilates about 50mhz so then i increased the power target to fix this. I then maxed out the pt and voltage and ran again and my core clock was all over the place. Maxed out is 1.175, if i move it down to 1.075 i can get a +175 clock offset and +375 mem clock increase with a good rating on heaven but looking back at the graph my gpu clock line is still not perfectly straight i get some divets.

I dont have vsync turned on and my gpu usage is at 99% when benchmarking

Is it ok to ignore the gpu clock graph and just shoot for the best heaven benchmark i can achieve?

Do you think something is wrong with my card or even my power supply? no matter what i do i cant get it to run at max voltage.

im new at understanding all of this so any help would be great, thank you

Overclocking is luck of the draw....the "best chance" to get significantly higher than reference clocks is to get a high clocked factory OC card....but that doesn't guarantee you the best overclocker...that could be a plain vanilla...or not. There are many components that come into play, and all are far from being created equal, and anyone can be a un passable road block. With factory OC card you are guaranteed an OC of whats on the box...nothing more, though often times you will find a little more headroom with the steeper factory OC cards.

I also recommend have a look at this link to help you max your oc stable ~~The GTX 670 Overclocking Master-Guide~~ http://www.overclock.net/t/1265110/the-gtx-670-overcloc... I also know about some "magic bios" but since your fairly new to this i am not going to get into telling you about it since you'd most likely break your card.
