You must have it set to auto-voltages, because unless you have some form of super chip, it wouldn't run stable without changing the voltages.
There is no i9 processor. It doesn't exist.
First off, the i9 processor IS the i7 980x. They changed the name extremely late in production. The only thing that is changed is the semantics. Are you really the kind of person who will argue to the death based on semantics?
As to your first point, no I did not set to auto-voltages, my voltages are all set to default. It runs perfectly stable up to 3.5GHz. You should've read that link I gave earlier in this thread.
http://www.xbitlabs.com/articles/cpu/display/core-i7-920-overclocking_11.html#sect0We decided to find the maximum frequency our Core i7-920 processor will be able to hit without any additional voltage increase. For this experiment we locked the processor core voltage and Uncore voltage at their standard 1.2V in the ASUS P6T Deluxe mainboard BIOS.
To avoid any unexpected surprises during overclocking, we disabled EIST and Turbo Boost technologies and locked the CPU multiplier at 20x – the default setting for Core i7-920 with 2.66GHz nominal clock speed. We set 8x multiplier for the memory. Therefore, since Uncore frequency should be at least twice as high as the memory frequency, we used 16x multiplier for it. To get the desired QPI frequency setting, we used the lowest available multiplier of 18x.
With these settings our BCLK frequency reached 175MHz without any stability issues. By the way, we tested our system stability using 64-bit Prime95 25.7 utility in Small FFTs and Blend modes.
As a result, our processor overclocked to 3.5GHz, which is a pretty good result considering it worked at its default 1.2V Vcore. The maximum core temperature during the stability tests never exceeded 74°C.
I use the same settings, and get pretty much the same temperatures, sometimes mine gets hotter by 1 or 2°C since I use a different heatsink.
Now, please stop arguing with me if you aren't going to actually look up any of your inane statements yourself.
Also what's the difference between the i7 920 and the 930?
The 930 is the new version of the 920. They are the exact same in architecture and revision, the 930 just has a higher clock speed. They should be the same in cost, but go with whichever one is cheapest if they are not.
