Darrell, it is very important to let you know that we don't recommend or support over clocking any of the internal components such as memory, video or processor. This practice could decrease the lifetime of the processor and it could damage it. In addition to that there is no warranty support for that practice.
Please keep in mind that when a processor is over clocked, it increases the core voltage at the cost of system stability, power consumption and heat dissipation. The reason why there is 1 core reporting higher temperature is because the CPU chooses one randomly and uses it more than the other cores.
What I would recommend you is to access the BIOS and reset default settings. Then, test the system without being over clocked and check the behavior.
Thank you for your understanding.
I know the potentials in overclocking as Ive done my research. I understand you have to tell me that in order to alleviate any liability. But saying Intel doesnt support overclocking is like NASCAR saying they dont support speeding. Intel releases K series processors for this very reason just like Cadillac releasing V type models. No matter, I have corrected my issue. ASRock's offset voltage was causing the problem. Once I changed it to fixed and set it to 1.31v, Prime95 tested fine for an hour @4.5GHz and ran 3dMark w/o crashing. Still having high heat, so I dialed back to 4.3GHz @ 1.29v and temps dont go past 85C except on Core#1 which is always 5C higher. 3DMark Benchmark hardly noticed. Think I lost 5 marks. Oh well, system is stable.
Thank you for your assistance in informing me on Intel policy though... much appreciated.
