what volts do u use for 4ghz?
under load the voltage is ~1,39-1,40V (bios 1,45 in windows idel 1,424)
But its only spi stable, i think would need another 0,2V to get it prime stabel but that means core temp nearly at 80°C.

heres a pic of a QX9650 with VID lower than 1,1V

Yeah VID and starting voltage will decide what temps/oc/power you get in the end. Early ES guys had 1.1V stock volts and 1.0xx stock VID and were getting high clocks@low volts.

That 70C looks incorrect or its reading TJunction because by 64.5C Tcase (IHS) your core is automatically throttling and modulating 30-50% as a safe guard for damage. QX9650 is designed to only operate safely at a maximum of 64.5C before TCC kicks in and drops the clocks and the voltages down because its exceeded maximum safe temperature and PROCHOT gets asserted. Thats the limit before you get a damaged processor. (see Intel QX9650 specs). Not sure what is happening with Core Temp there.

Also have you measured the VCC using a DMM when you set it in BIOS and after bootup?
You have to remember that the Core temp is not Tcase temp. Coretemp is the hottest spot on the die while Tcase is measured on the center of the IHS. There is no way to measure tcase (apart from modifing your IHS).

Afaik Tjuncion temp is the temp where the cpu should beginn to throttle, i think the cpu will stat with throtteling when the temp reaches nearly 100°C (its not the whole cpu, just the hottest part that reaches this temp).

i haven't measured VCC with a DMM right now, first i need to know where to measure it.
