sorry but, Tcase is something different then Tjmax
tjmax and tcase are measurements of different locations.
tcase= top of the IHS.
tjunction = temperature of the die itself.
Intel's DTS is calibrated to read distance to tjmax, and this is where most temp monitoring programs get their numbers from.
They then give you a temp based on what they think tjmax is by subtracting the the distance to tjmax.
If tjmax is set to 100C, and your CPU cores are running at 80C, you aren't past that 72.7C limit. You are well below it.
The temperatures are calibrated to totally different locations.
The assumption is that, within normal TDP values, with an unmolested IHS, the top of the IHS won't reach 72C until the cores hit ~100C (or whatever true tjmax is).
i cant find any vcore max or recommended ones in the data sheets you mentioned

So for 4.4 GHz I think you might be good with anything between 1.150v and 1.200v. Every piece of silicon is different so you really need to test things out and see what works best for your system.
And the fluctuation thing really can't hurt. It's just the Intel power saving functions kicking in and I don't think there's a way to turn that off.
theres a way, you can disable them in your bios
but its a great feature, so why would you right
just some info about it..
EIST(desktop) dynamically increase/decrease its clock speed between its minimum clock and its normal operating frequency, as well as voltage, in order to optimize for power consumption.
in other words a performance reduction while using the system, the system may feel you don't need full power. drats just heard a drop out.
C1E Halt: while similar reduces Clock speed by adjusting the multiplier (Core clock to system bus ratio) and to some degree VID. (voltage) this is a more common occurrence with light use
or on today case of Multicore shutting down a core or 2.
C3, C6. This is a deeper sleep with a complete core(s) shut down (Gate off) and no voltage/Data at all. harder to recover from quickly, previous data is cached elsewhere and needs to be re-cached in L3 memory
to re initialize full muliticore, multithread use. Part of Core parking
by default they are enabled in the bios, or on Auto,
i only disable C3/C6 when ocing, for obvious reasons i think ..lol
k, enough of me and info, i dont want to mess up Faelore's thread Edited by VonDutch - 1/22/13 at 4:52am
