Default i7-860 Overclocking

So I know RAM for i7 always stay under 1.65v to prevent frying the CPU.

But what about max vcore for safe 24/7 operation? I know for 45nm Core 2 it's around 1.4v for safe 24/7 use.

What about an i7-860?

Do I have to worry about running RAM and CPU at 1:1? I don't think so with i7 right? Is the BCLK quad pumped like in Core 2?

I know general overclocking theories still apply...but seems like Core 2 compared to i7 is a totally new and different overclocking method.

Temperatures will keep you from using more than 1.4v on an 860.

keep yours temps under 90C on an i7 and your fine for an i5 80C and under. For both wouldn't recommend going more then 1.45v.

90?! It can go THAT high? Is this according to Core/Real Temp with 72.7C as the Tjunction set according to Intel® Core? i7 Processor I7-860 - SLBJJ ?!

I guess based on what Eldonko has said, I'll be around 90C by the time I get to 1.4v...

Depending on the amount of air that your fans push, you might hit 90C with HT before 1.4v with LinX and OCCT.

please read your setting the wrong thing the temp given by intel is max ihs not tjuntion

Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor’s automatic mode is used to indicate that the maximum TJ has been reached.
