I'm really not sure about this particular processor but a bit of google-fu reveals that this processor typically gets to 3.2 - 3.3GHz. What I'm not sure about is if this is on the stock cooler or otherwise. To my mind, a stable overclock to 3.1GHz on a stock cooler seems pretty good.
One thing that may be worth considering is to see how far you can get the NB/L3 cache to overclock as this may yield better performance results than core overclocking alone. However, I do have to stress again that I don't have any experience of Kuma or original Phenom overclocking.
Finally, I would be surprised if you damaged the processor by trying for 3200/3300 clockspeeds, so it may be worth gently pushing the cores up 100Mhz at a time then stress testing to see what happens. Of course, doing this properly is a time consuming process.

Amd 7850 b.e. overclocking - need help
hello
i just recently got a amd athlon 7850 BE and seem to be having trouble getting a fully stable OC. i was doing some research and ran across a forum where someone got the CPU up to 3.5ghz on stock cpu voltage (1.325) and found this curious because my system shows that my voltage at 3.16ghz was 1.5. i looked in the bios( motherboard is a biostar mcp6p m2+) to find a setting for cpu voltage and found a an option that would let me add 3.3% of the stock voltage, but nothing to decrease it. so my question is, is the higher voltage part of the issue, and if so is there a way to lower the voltage?
