I'll leave it on overnight doing nothing see if it's stable.

Most 3570's idle somewhere around .900-1.000. what is your full loaded vcore for 4.8?

I am going to leave this here for you, you should read it. The extreme4 has a voltage reporting issue and you are likely receiving much more voltage than what you are seeing in software. Several members with DMMs, including myself, have confirmed the problem. So be careful, you might already be pushing 1.400+ READ ME & WATCH THE VIDEO

No, the margin or error scales slightly with higher voltage and LLC, but all voltage levels and all LLC settings are affected.

hmmh, I don't have a multimeter to check this so will just have to hope that's not the case.
I'll set another OC profile without LLC to lower the margin of error as precaution.

It's the easiest place to start your search as to why now.

Thanks for the responses.

I had another issue occurring during this time and wonder if this may have been the cause.
A week ago my 6970 just kept BSOD and the dump was showing display drivers, etc so I swapped this out to my old 6870. The HDMI cable I was using on my primary monitor was not providing a "tight and snug fit" at the connections and the screen was dropping in and out and had to be jiggled from time to time to try and get a constant display. This was happening with the 6970 as well before the BSOD issues kept happening. The PC kept dropping into sleep states and could not be woken and would require "resets" with both cards.

Could a dodgy HDMI cable be causing power spikes to the Video Cards and system?!?

So far I updated to the latest BETA BIOS but also swapped over the dodgy HDMI cable with another I had.

I have gone the lazy path atm and just grabbed the OC 4.0GHz Profile in the new BIOS and have good stability for daily use atm since writing the post and with display staying on constantly. I will find some time soon and investigate this more thoroughly.

vCore is going from 0.99 to 1.3 but no real load/stress test yet. No offset/Turbo yet either.

The PSU is an Antec Quattro 1000W so I have a lot of confidence in it.

Is there anything wrong with clicking the predefined OC settings in the BIOS? I loaded up the 4.2 OC just for S&Gs and it's been super stable and temps are great. I know I can probably squeeze more out of the system with a real OC but what's the difference between doing it this way and the "hard way"?

Auto overclock has been know to apply too much voltage for each multiplier. I'm not a big fan of any auto OC feature that comes with motherboards now. Auto OC dumbs down Overclocking IMO so that any one can do it.

You will not only learn much more about system tuning an how the system reacts to certain changes with a Manual OC, you will also usually end up with a Higher, more efficient OC .

Actually the presets on this board are pretty good. I have had slightly lower voltage on my preset than the what the OP guide has had. I run the 4.4hgz 24/7 and have had no issue or voltage change with the 4.6ghz preset. If you want to push it beyond that then you will need to go manual and tweak stuff on your own.
