ve been working with this amd fx 6200 proccesor for a while now trying to figure it out. Factory it came at 1.372 cpu volts. I disabled everything in the bios having to do with power saving, turned of turbo core, and it fails prime 95 on stock voltage. If I increase it to 1.380, its stable. For 4300mhz (200x21.5) for it to be stable it requires 1.432 volts, i tried for 4400mhz and it would only be stable at 1.480 volts. Can't do 4500mhz because my voltage only goes to 1.512. I tried increasing the cpu nb volts a little and that helped. But are these normal voltages for this processor? If not, what else could I try for stability? 3800mhz is boring lol. I'm water cooled so temps are fine while running tests.
I should also add, i have 16gb's of ddr3 1600mhz memory.

A lot honestly. Mostly the quality of the voltage supply/regulation systems on the motherboard. Obviously the CPU will also have something to do with it as not all chips are created exactly equal. Some will require more or less voltage than others but it all starts with having a good overclocking board. For example I used several lower end boards before this one and I would have to use 1.4v just to get a 4.2 Ghz OC and it would be crazy hot in no time and throttle the VRM's causing the CPU clock to drop. I went to this asus and bang all problems solved. 4.5 rock solid on stock voltage and temps rarely pass 50c with a 212 Evo.

Thanks, I've heard the same from others. For the price, its an excellent board but my other components are not reaching their potential because of it's limitations. I'll look into getting a new board. The bios sucks on this anyways.

I have the M5A99FX Pro 2.0 which is basically the same exact board that bouncedk suggested (Pro has full 2 X-16 pci-e bandwidth Evo has X8/X16, seriously the only difference) These are great board for overclocking. I hit 4.5Ghz on my 6300 with stock voltage 1.36. I can definitely second this suggestion.

What makes the difference in the ability to overclock without raising the core voltage?

Oh also sorry one more question, with the FX series when your overclocking with just the multiplier, is the vcore the only voltage you have to change? Ive heard possibly the cpu nb voltage has something to do with it, not nb voltage, but cpu nb voltage.

If I could change this to best answer I would, thanks a ton.

You also had a great answer, I learned a lesson. Dont go with a budget board if trying to build a good system. Like a ferrari with a volkswagon engine. ;)
