Thanks.

Well I will try to see if it's 4.2 Ghz with current Vcore.
Download the NB to 2600mhz as you say, to see what happens.

@ Dark Mantis: Now hang a picture, I've seen to loop, and it is amazing! If you live somewhere it gets cold, temperatures have to be amazing! ... xD

They can be but I tend to use the external radiator in the summer months more as during the colder months it can get too cold and cause condensation problems inside because of the difference in temperture of the cooling liquid to the indoor ambient.

WOW, then you live must be quite cold .. xD.
Here on the island (Tenerife) in the month of December and we are at 17 º c, and almost no rain ..

Returning to the issue of the OC, I have the CPU already more or less stable at 4.2 Ghz and 2800 in NB.
But I have a problem ... and not get to spend the linx to 1.50 v.
A 4.3 GHz and 1.48 V to lynx, but fails by instability.
Then I put 1.50 v 1.55 v and not even pass me the linx, just run it, restart the PC alone.
That that happens? have any limitation of voltage?
Is the 1 st time I ride a PC with an AMD CPU and I'm kind of lost the truth.

Hi,

yes, if BIOS notices a problem with overclock settings then it can restart the PC and reset to safe settings. This is to help protect the motherboard and other components.

I have to say that I couldn't get past 4.2 GHz very easily with my own system and as I am not into overclocking I didn't spend too much time trying to go any faster.

Wow, that bad ... :-\

And there is no way to remove this security system?

it's not a security system as such, it just recognises that the settings made are likely to cause damage to the motherboard, CPU or some other component and as it is part of the BIOS I don't think it can be turned off.

This is where the challenge of overclocking really kicks in and it is only through experimenting that you will find the limits of your own system. As I said before, I struggled to get above 4.2GHz and gave up at that point because I was only doing it to find out how far I could easily go and so that I could offer advice to others if needed.

I finally settled on 3.8GHz but lowered the CPU voltage down to 1.325V which gives me lower temps but a reasonable speed increase and system stability.

Okay, I understand, well then I will have no choice but to try to get as often as possible below 1.50v.

This issue could be solved with a new BIOS?
I've seen people who feel the same even with the 890FX UD7, and the truth which is a shame, buying a Black Edition CPU, and not being able to get the most performance, a limitation of voltage.

Known whether this board will be taken to new bios? or 790X/GX/FX and lay them aside for the new 890?

Not sure about future BIOS updates but you might like to ask Gigabyte Technical support about this and the problems with increasing the voltage above 1.5V.
You can contact them here: http://ggts.gigabyte.com/tech.asp?ClassID=2&Country=Spain&SourceWeb=B2C It could take a while before they reply.

One question, that actually serves the CPU VDDA? Comes by default to 2.50 V, this voltage I touch it?

As the NB voltage, so I have a 1.12, which is the default, I have to give more power?

Thanks.

Yes, you can increase this voltage a little for better CPU/NB stability if needed. I didn't need to adjust this setting though so be careful when you do increase it not to make too big a jump.

As the NB voltage, so I have a 1.12, which is the default, I have to give more power?
You might find that a small increase to the voltage will help. I had to use 1.150V on my O/C for stability

Thanks.

It is normal for this motherboard come on CPU PLL to 2.50 v? and the minimum is 2.20 v? it is way too? I remember my old Q9650 with 1.60 v enough for a good OC, I guess that AMD platforms will be different, right?

Yes this is normal and the maximum is about 3.1V if I remember correctly.

In a word, yes. AMD & Intel handle things very differently.

Thanks.

I ask my last question on the AMD platform.

I've seen the voltage SB / PCI / PLL, so called, and comes by default 1.80V.

I recall that the 775 platform to put this voltage is 1.50v, so, as I put it here.

For this platform, it is natural to use v 1.80 for PCI?

What is the recommended voltage for use 24 / 7?

If you load optimised defaults in BIOS and  then re-boot your PC all voltages will be returned to their default states. These default voltages are safe and recommended for use 24/7.
Before you begin over clocking it is a good idea to take a picture of these settings in BIOS  or make a note of them in the User's Manual (which is what I do) so that you can have them readily at hand to reference when tweaking.

NB/PCIe/PLL Voltage Control is set to 1.8V by default and this is normal.
