At 3.5GHz with stock voltages the Core i7 is stable, but the temperatures are very high. Running Prime95 the cores get up to 92C. It is stable, but that temperature is just too high. I tried going to 3.6GHz, but to do that I needed to raise the CPU Core voltage from it's stock 1.2V to 1.3V. At this point the temperatures shot up to 100C and the CPU automatically lowered the multiplier to keep it from getting damaged. The CPU cooler I'm using is the one that comes with the CPU from Intel. It does a good job at stock speeds and even moderate overclocking, but I need a better one to continue. I've ordered an Arctic Cooling Freezer 7 Pro Rev.2 from Newegg.com. It should arrive on Tuesday. Until then I'm going to keep working on the first and second lessons.
The first lesson will cover the basics of overclocking and will be a similar format to what you see in our Home PC Builder 2009 component lessons.
The second lesson will be in the BIOS, showing and explaining all of the settings that are available to overclock and getting the CPU overclocked to 3.5GHz.
The 3rd lesson will show installing the 3rd party cooler we have on order and then overclocking the CPU to 3.6 and then 3.7GHz.
The 4th lesson will show overclocking to 3.8GHz which may be the maximum the CPU can handle. We will try 3.9 and 4.0GHz, but from what I've found on the web it may not work, at least not at safe voltages.
Don't worry, we are going to cover every step just like in the Home PC Builder 2009 videos. After watching these new overclocking videos you will be an expert. The first video should be online by the 14th and the rest will be online by the end of December. Customers with online access to our videos will be able to watch them at no additional cost.
