Your understanding of the specifications is incorrect. 1.3625V is the upper limit of the VID range for 45nm desktop Core 2 CPUs, meaning that the default voltage setting for a CPU coming out of the factory must be that number or lower. The maximum voltage is actually 1.45V, but the maximum safe voltage is 1.4V if you take into account the 50mV maximum voltage overshoot limit.

As for the temperature, 74C is the thermal specification for the CPU, which has nothing to do with any temperature limits. The thermal specification is also a Tcase value, which is measured in a completely different way than the temperature measurements we can get through software. The maximum temperature as far as the CPU sensor readings go is technically 100C, although it is still impossible to actually damage a CPU with high temperatures since all Intel CPUs have built in thermal protection to prevent that.

So, to summarize: the maximum voltage is 1.4V, the maximum temperature is 100C, and since it is extremely unlikely that you will run into either of those limits during normal overclocking, there really isn't anything to worry about.

MCH/DRam Ref should be 0.910v for 3860
MCH/Dram ref should be 0.920v for 3600
