Hi guys, I just recently received a EVGA GTX 680 Classified last week. Some awesome dude wanted to trade me his 4GB Classified for my 2GB Signature edition so I couldn't refuse.

Now, I've been trying a bit of over clocking with it using PrecisionX. I've seen much stories where people will be reaching 1300mhz clocks no problem on stock air cooling and I thought that I would give it a try. I followed the master GTX 670 overcloking guide (awesome guide btw, reason why I joined this forum in the first place is because of the amazing support and advice) but the only clocks I could muster was 1250mhz (+74 offset) and +112 offset on the memory clock with voltage tuned up to the "max" 1.175v and power target at 113%. I'm still learning what people mean by "I have over clocked my memory to 6xxx" so if maybe someone could clarify that for me too? tongue.gif. After that, adding +1 to any of the memory or clock speed will crash the Heaven benchmark. I know that cooling can't be the problem because even at 44% fan speed the temps don't exceed 60 degrees celcius. Although, with just 100% and stock voltage my over clock still runs as smooth as butter with no artifacts or anything.

Now, I just want to know if that's normal. I really want to hit that 1300mhz mark if there's a way. Maybe the classified I got was just a bad card? I'm not complaining, as it was pretty much a free upgrade (my old signature 680 couldn't even get past 1220mhz) but it would be nice to play BF4 with a few more FPS. smile.gif

If it helps, I am currently running the most current NVIDIA driver. (331.65)

Any suggestions or advice will be much appreciated!
