QUOTE(lchee @ Jan 20 2011, 05:26 PM) When i go to my computer icon, right click and select properties, i see my computer system properties. Processor speed it states 2. One 3.3GHz, the other 5.8GHz. Why is this so? Is this common to all i2500K that overclock? I did install core temp to monitor CPU usage and temperature. When running Unigene, I notice the clock ranges from 1566 MHz to 4498MHz (I set OC to 4.5GHz), and sometimes even hit 5800MHz (though for a short few seconds). CPU highest temp recorded was 51°C. Is this normal? If you use the TPU switch to OC , it is very normal. speed fluctuating because speedstep is enabled. |

guys, wanna ask something here about the memory pairing with sandy bridge cpu before i buy sandy bridge. because now still not many ram special made for sandy on sale ( except ripjaws x series, but hard to get in malaysia). so my question is will there any chance a kingston 2133c9 , dominator gt 2133c9 or dominator gt 2000c8 and clock the speed at 2200 cl7 something like the ripjaws x speed? cause i know the sandy bridge memory controller is stronger right?

QUOTE(lchee @ Jan 19 2011, 12:19 AM) I just overclocked my i5 2500K to 4.5GHz using some internet posted settings. It works easily. My first attempt in overclocking after using PC for more than 10 years. It was surprisingly easy. I get like additional 1.2GHz... wow... Now, how do I benchmark my PC? Is there a standard software ppl use to benchmark their PC scores? mind to share the source ??  |

Enter the Advanced menu by clicking the button in the top-right corner 3. Set the CPU multiplier to 45x 4. Enable Load-Line Calibration 5. Set the CPU voltage to 1.3-1.35V 6. Set the CPU PLL to 1.9V 7. Set the VCCSA to 1.1V 8. Set the VCCIO to 1.106V 9. Hit F10 to save and restart |
