Overclock Athlon 860K with GA-F2A88XM-HD3

[AshBD]

Hi,
I am a newbie who wants to overclock my AMD Athlon X4 860K with Gigabyte GA-F2A88XM-D3H motherboard. I can increase the CPU clock but can't understand the voltage part in the BIOS of this motherboard (BIOS version is 8). The value of the vcore can be changed to Auto, Normal and from 0.000 to 0.300. I don't understand to what value I should change it to. My target is to increase the clock to 4.3 GHz where I believe the voltage should be around 1.4. Then to what value shall I change the vcore to? Could anyone please suggest?
Kind Regards!
- Ash.

Auto will increase the voltage exponentially as you increase the multiplier.(this setting will normally overestimate the voltage required substantially) - it will offer stability at the cost of higher temps & power draw.
Normal will keep the default stock voltage no matter what you do multiplier wise- will create instability past a certain clock speed.

Your manual setting will allow you to increase the voltage in tiny increments over stock voltage.

What you should be doing to begin with is setting voltage on normal.

Increase multiplier by 1 or 2 ,(50-100mhz)
Boot into windows
Do a prime stability test while running overdrive for temps & voltage monitoring.

If it passes rinse & repeat.

When you hit instability while prime testing drop back to bios & set voltage to 0.025 & test againagain
Still fails , up it to 0.035 & restest - keep repeating 0.045/0.055 etc until you get a stable result

Every chip is different - you may hit 4.3 on stock vtage, you may not.

Never ever increase multiplier or voltage in big increments in one go - play it safe , small increments & then test - it will pay dividends on the result you get.

Thanks a lot. It worked perfectly this way

Np mate - what clock speed did you get yourself up to??

Well, I am not pushing it that much yet. Reached 4.1 GHz in stock voltage so far. Will try more soon but I am quite happy with it at this moment.

I'm a newbie as well I have an over clock on an 860k of 4.5ghz at 1.4750v on an f2a88x-up4 and Northbridge at 2000 I ran AIDA64 for 8 hrs temps stayed between 65-72 I have an alarm in case it goes above 80*c so far so good I've gamed watched movie did other tasks and it seems pretty stable
