HELP over clocking

[NeWYoRkLeGenD]

Hello im new to overclocking. I have an AMD FX 8120 and the reason I want to overclock it is because when I play SC2 it seems sluggish and I have a hard time microing with many units on the map. I downloaded OCCT and ran it with stock settings. I see the max my processor hits is 1406 MHz. I should be getting at least 3100 MHz stock correct? When I run the test does it stress the CPU to keep it at max settings ? I just bought and installed a EGVA GTX 760 superclocked. I doubt my video card is making the game play sluggish especially since ive read that SC2 is demanding on your CPU. I just want a smooth flowing game. Any ideas?

System Specs
Power supply - 600w
GPU- EVGA GTX 760 Superclocked
CPU - AMD FX 8120 eight core processor 3.1 GHz
Mother Board - ASRock N68-VS3 FX

Try disabling the low power usage in the Nvidia control panel and see if that helps. If not, what kind of PSU do you have? It might not be able to handle overclocking or delivering clean power to your system.

Thank You for the quick response. How can I tell the brand name of the power supply? It just says 600w under the description where I bought it....here is the link... http://www.newegg.com/Product/Product.aspx?Item=N82E16883227408

Im still confused, even at stock settings when I use the OCCT program shouldn't the CPU still max out at 3100 for the duration of the test? It stays at 1406 MHz.

PSUs in pre-built systems tend to be pretty low quality. As far as OCing your AMD proc I can't help much there, haven't used a AMD chip since socket 939 days.

I also just realized at stock settings when using the OCCT program I see the ram goes up to 100 percent during the test , the frequency stays at 1406 and the temp rise to 81c. Is this just a bad CPU?
