Gigabyte GA-EP43-DS3L + Q8200 overclock doubt

My system is a EP43-DS3L, Q8200 cooled by a CoolerMaster TX2 2x2GB Markvision 800Mhz sticks, two sata hds, sata dvd burner, a 9400GT and zalman 360W PSU.

I am just starting to learn how to overclock and have doubts.

I had the Q8200 running @ 2.80 for 3 months with settings: 7 x 400

the only things I have adjusted were locking PCIe on 100Mhz and putting the vcore on normal instead of auto..

My question is the following: I haven't fixed a value for CPU Termination and CPU PLL and other things, so the mobo was regulating these voltages, is there a risk of these voltages getting too high on auto?

How's about these other voltages when they are on auto? The motherboard put them high when overclocking?

Is it dangerous to the mobo and the processor? BTW the processor temperature was inside the thermal specification and tested good on 4 threads of prime95 for 5 hours.

someone using this board on 1600 FSB on a quad?

Thank you

PS: I am not overclocking anymore, cause the other day I got the BIOS and there was an warning about voltages, and the processor was no more on overclock it had returned to the default clock setting.

I can't seem to find the article regarding this with a quick search, but I believe term and pll are set by the motherboard as a percentage of your Vcore, unless you specifically alter them. I also understand that this is not optimal for the real hard-core overclockers (the guys who are running 1.45 Vcores, with their fingers crossed!), who often do hardware mods to this circuitry... GB MOBOs have two oddities regarding this: 1, you can set most voltages ridiculously high in the BIOS - high enough to toast components pretty much instantly; and 2, the warning voltages are usually ridiculously low - my BIOS shows and DDR2 voltage at or above 2.0V with a red warning, although nearly all 1066 is rated at either 2.1 or 2.2 volts! My guess is it's a CYA thing to be sure you can't blame 'em for cooking any of your components... So, all in all, don't worry - if you aren't 'cranking it', neither is the board!
