hi i overclocked my q6600 to 3ghz and was happy with it.
i then went around to lowering vcore to as low as possible. i got to 1.25 volts. any lower than that then it would report errors in occt and p95.
i then underclocked it back to stock 2.4ghz, and thought i would see what its lowest vcore would be as to have lower temperatures. however i managed to get all the way to the lowest possible setting of 1.1 volts... and occt and p95 worked fine.
im slightly confused as i would have thought at the lowest possible setting the cpu would fail to run?
does all this sound right ot you?
