1)Now I can oc q9450 to 3ghz or less but I read if I just bump fsb and leave voltage on auto it will over compensate and over volt. I did test and set the overclock setting to manual and I don't see the available voltages or can't even tell my stock voltage, so is direct key input the only way do it and does it require approximation?
2)Everest home edition reports my CPU VID 1.2125 V , is this really my stock voltage?
CPU-Z reports my core voltage as 1.84 but it fluctuates to 1.60.
3)I would like to achieve this on a stock voltage if I can even figure it out, and is 3.0ghz stock a good goal to shoot for? This is my fists time overclocking after reading how common it is.
4) to set manual voltage how do I check my current volatage and do I need to run prime95 to see if its stable?
Thanks for your time

1. You should not use the Auto voltage setting for the core voltage. You do not want to approximate either. 3.0 Ghz is a relatively simple OC.
2. The VID is sort of the "stock" voltage for your CPU. 1.2125 is lower than average. Lower is good.
3. Set your CPU voltage to the VID. Then start pushing the FSB freq upwards until Prime95 fails. Increase the CPU voltage a couple of steps and continue testing. Work back and forth between FSB and CPU voltage until either you reach 1.45 volts or 70 C load temps on the cores.
4. You should test for stability with something. Many of us use Prime95. There's a fair amount of discussion about how long to test. Consensus is 4 - 6 hours is long enough. I stress test for 24 hours.
i ran prime95 for 4h and its stable at 2.8ghz. push it to 3 now>?
I'm not sure if you are, or rather, you did actually use 1.8 volts to power your CPU, or if you were mistaken. If that was your voltage, the CPU will not last another 6 months... if it lasts another 6 days. It is very dangerous (for your hardware) to run that much power into the chip, and as jsc explained, the absolute maximum voltage for your processor is 1.45v.
Anyway, it would help to run cpu-z and check to make sure your voltages and clocks are correct. If you don't have cpu-z, you can download it from this website: http://www.cpuid.com/softwares.html
If prime95 ran for 4 hours at the stock voltage you posted, then that's a great start. You should certainly turn up the voltage though if you'd like to try for 3.0ghz. Try ~1.26
And yes, at 3.0ghz you should be using all of the GTX 570.
If you're running at 2.8 ghz with 1.21 volts, that's very good. Try ~1.26v at 3.0 ghz, and let it run for about an hour, or rather, let it pass 4 seperate tests and go into the 5th. If no instability, lower the volts to ~1.248.
