My Q6600 was reporting very similar numbers to those at 3.4. At FSB 377, it needed 1.325 (BIOS) for stability (1.28 full load CPU-Z). Temps were at 57*C.
It starts to become more power-hungry at and beyond 3.45 GHz. Currently, I have it 400 FSB and 1.43125v BIOS (1.408 and 1.376 idle and full load respectively, CPU-Z, with full load occasionally flipping up to 1.392 and back down to 1.376 while running large FFTs). 17 hours small FFTs stable. Working on large FFTs now. Temps are at 63*C.
It gave a Prime error at 1.4125 BIOS at 400 FSB. Bumped it three notches to the final 1.43125 (BIOS), just to be extra certain (and also because CPU-Z was not showing me a bump in voltage until I went to 1.43125).
The point of all this rambling is that I'm confident your chip can go to 3.6 as well. I'm more or less convinced that the latest G0's are very efficient processors. My brother has one running at 2.7 GHz and 1.175 BIOS (1.08 CPU-Z), which is notably lower than stock voltage.
No, I would not worry about it at all. It may be giving you a warning because the intel "max voltage" is listed at 1.35v. However, I have a feeling intel specifies it at that voltage because their crappy included heatsink can only handle voltages that high.
Regardless, your mobo is probably overvolting the thing, they always do. What frequency are you running? Do yourself a favor and check out the Q6600 overclocking guide here on the overclocking forums. It's very easy to go into BIOS and manually OC. You end up with a far more efficient OC that way.
Goodie: I'm talking about CPU VTT. CPU VTT is NOT CPU vCore. CPU VTT is also known as FSB Termination Voltage. It has to do with the signalling on the motherboard.
And almost Evilonigiri.
vDroop = Idle to Load voltage droop.
vDrop = BIOS to Windows (also known as vOffset).
Atleast I think the Drop is what you were referencing. Unless you are talking about droop preventing a spike over the VID. Which is also what drop is there for because it will spike after heavy load to idle.
But yeah I was referring to the droop to prevent the voltage going higher than the VID. Works both ways doesn't it.
Lol, there's too much stuff to know it all!
But yea.. VID is the max spec set in BIOS, offset brings that down to idle levels so that when it spikes after heavy load to idle it won't go over VID. Vdroop drops it below vOffset level so that it won't spike from the offset point over the VID... Haha.. It gets confusing.
