Emphasize the word "may" there.
The lower power consumption when idle is because C1E is enabled, even when using manual voltage. CPU cores will rapidly transition back & forth between C0 & C1E states. When there's task to be process, CPU can quickly enter C0 state & when task is done it will enter C1E state.

If you enabled C3/C6 states too, especially C6 state, it will helps lower power consumption when idle. When C6 enabled, just like what happen with C1E, CPU will rapidly transition back & forth between C0 and C6 states. In C6 state, the voltage drops down to nearly zero. When using C6, majority of the time individual cores enter C6 states. So, when using C6, there shouldn't be any difference in power consumption with either offset voltage or manual voltage. Therefore, you can continue using manual voltage.

I don't monitor my idle power consumption before but while I'm writing this post, CPU power consumption is ~25 - 26W with lowest is ~23W. C1E, C3 & C6 are enabled (not Auto). You can monitor C States using RealTemp T|I version.

gotcha, so it sounds like an alternative to higher multiplier simply for sake of overclocking and stability. "MAY" i know, Thanks for the info ... i was trying to find any reason i should try upping my bclk more or just be happy with what i have

And a final run @ 5130 Between 60c - 72c

Can you please upload those pics at a higher res ?
Atm its impossible to read on a mobile device.
Thanks.

Power cut here atm so my pc can take this time to cool down :-P

And what voltage you need for that clockspeed?

In his notes on that pic it shows 1.555v in bios

Atm it is running @ 1640mhz with 1.55v

Would using faster ram improve overclock and stability?

you would defiantly see performance boost

Thank you for your posts, your really making me feel good about pushing more through my cpu when i finish my watercool setup. +Rep! thumb.gif


Has anyone encountered an i7 3820 that won't do Gear ratio/Cpu base clock ratio of 1.25strap?

any tips?
The vcore for that clock looks niiice thumb.gif Have you tried Stress testing that on P95 for a few hours yet questionmark.gif
