Intel i7 Data Sheets - Limits

I used to have a thread here bookmarked which contained this link. It's gone now, so for those interested.

Voltage limits on page 22

Temperature in Chapter 6

Well one thing is, just cause it says 1.55 is the voltage limit doesn't exactly mean you can go that high safely.

Taken from a freind over @ Overclock.net

1.) Electrical Specification must be satisfied (1.55v for 65nm CPU and 1.45v for 45nm CPU)

2.) Signal Quality must be clear (Overclock must be perfectly stable, GTL lanes may need to be tweaked)

3.) Mechanical specifications met (There is not a physical defect and the insides have not previously been gutted by running 1.9v through it)

4.) Thermal Specifications must be satisfied (The IHS temp must be below Tcase)

two important things to keep in mind

According to Intel, "Within functional operation limits, functionality and long-term reliability can be expected." This says nothing about running over stock voltages or stock clocks. Only that you need to be stable, cool, below the maximum voltage, and mechanically sound at any speed.

Moreover, if a device is subjected to these conditions for any length of time then, when returned to conditions within the functional operating condition limits, it will either not function, or its reliability will be severely degraded.
