Hi epelj1, Do you have an aftermarket cooler? If not I recommend the Thermalright 120 Ultra Extreme. This is a must when overclocking as heat is any overclocker's nemesis. Everything is much more efficient at cooler temps. Having said that, it doesn't mean you will lose stability with a few more degrees and an overclocked system...if it's setup properly. Scary temps is when cores hit over 70 degrees celcius. The CPU itself shouldn't go over 70 degrees C, and if it does go over a certian amount the PC may just freeze or reboot to protect itself. I like to trust my own instinct though and set it so it doesn't get too hot. Usually this means finding the sweetspot voltage for the CPU, DRAM and NB. Voltages may vary between identical PC setup too. Checkout Post #54 , #142 and $151 for more details. For 3 GHz not much is needed. Just keep in mind that if you only overclock the FSB, the DRAM will automatically overclock as welll. Make sure oyu manually set that or put it to a 1:! ratio meaning the CPU FSB and DRAM FSB are evenly working together at the same rate. E.g FSB 400 MHz and DDR2 RAM at 400 MHz (800 MHz after DDR). This is what is meant by 1:1 ratio. As you can see, somre pretty impressive FSB is needed for a good memory overclock. Besides the Core i7, the Intel CPUs aren't really dependant on memory clock, so long as you try to keep a 1:1 ratio as much as possible with a good CPU FSB overclock you should be ok. Don't go crazy with voltages, but it's ok to set them a LITTLE more than auto just to make sure you can hit the overclock ok, and then lower then until you notice instability. Then put it up to where you think it's stable and cool. In your scenario, just couple of notches in the volts should see 3 GHz stable. Hardware can vary so lets hope it doesn't requitre too much voltage to acheive your goal . Hope this helps.
