While it's worth mentioning that BIOSLEVEL's own Colin Dean contributed a translation to OCCT, we're more interested in how OCCT kicks the CPU usage up to 100% and uses what onboard sensors it can find to benchmark the system. In my case, it found a temperature sensor for the Core2 Duo, and several voltage sensors on the motherboard including vCore, 3.3V, 5V, and 12V.
I configured OCCT to run this stress test for one hour. The status screen kept me updated as to where the voltages were. I didn't see any concerning numbers, and everything seemed to be right on the dot. After the test was over, OCCT opens an Explorer window in the "My Pictures" folder, and voila, you have time charts of the voltages.
The first graph was the CPU's VCore. Core2 Duo processors can handle .85 to 1.362V VCores. Despite the 12% ripple, these numbers are well within the operating parameters of the chip.
The system's 3.3V feed was running a whopping 3.6% over what it should have been. This is very dismissable, and fantastic that we see no change in the voltage despite the CPU usage rising.
Again, we find a mere 2% difference in actual vs. required. The 5V feed runs at an almost constant 4.9V, never spiking to an extreme.
Finally, the main 12V feed. At approximately a constant 12.45V, the feed is only running about 3.6% over the required 12V. This is nothing serious, and should cause no damage to the motherboard or system performance.
Overall, the powersupply's motherboard feeds look awesome. The best explanation to the rise in the VCore voltages is most likely the motherboard or CPU itself drawing in more power as more of the CPU is utilized. The EPSPOW750PRO holds its ground is solid voltages all around, even when the system is under strain.
