So I have never been much of a great OCer, or that in general which is why I always turn to this forum... my question is...

Can I get more out of my AMD Phenom II X4 3.5ghz HDZ970FBGM?

Some background:
1) My MB is an Asrock M3A770DE & use a Hyper212 for Cooling.
2) I had an X3 in there that I changed the FSB from 200 to 230 and went from 3.0ghz got 3.45ghz out.
3) I use HWMonitor + CpuZ to check my temps and ID on the CPU.
4) I use Prime95 and don't change settings and blend it for a while to check stability.

My Motherboard had a default voltage in BIOS @ 1.475.
I'm at 1.4825volts 3.9ghz X 19.5multiplier.
Haven't changed any FSB.
Temps using Hardware Monitor hit 40c on max load /w Prime95, 20-25c normally.

I know inaccuracies exist with voltage reads + temperature measures and some consider using a digital multimeter.
Cpu-Z is reading 1.520V when BIOS voltage reads 1.485V.

Is my volts too high? Should I try under clocking it for higher ghz? (Is that even possible? I heard from Toms it might create more stability... etc.)

CPU/north bridge,set @2400mhz to stabilize CPU, maybe 1.25 to 1.3 volts.I am currently running same chip @3.9 GHz with 1.404 volts with a cpu/nb@2400mhz stable with an asus m5a97evo. Yours should see similar results.Try not to go over 1.45 volts,this voltage should get you 4.0 to 4.1 GHz stable..

your volts are high. you should always use the voltage needed to stabilise your OC, not much more. If your default voltage has led you to this you may try undervolting. never go above 1.5V on air cooling.
