Overclocking Intel E7500 cpu on a Asus P5Q board with PC6400 1066MHzCorsair ram
My system has what is in the subject, and so far I have used the Asus AI
tweaker to adjust the FSB upto 333MHz, which pushes the cpu frequency up from 2.9Ghz to 3.65Ghz. I have run Prime95 for 3 hours and the cpu temperature has not gone over 56C, but runs at 29C normally with a Titan Fenrir cooler. I did try the FSB at 400Mhz which pushed the cpu upto 3.9Ghz, but then my system became unstable after a short period of use, so I reduced the FSB back to 333MHz. Is there anything else I should/could adjust to get 3.9GHz cpu speed. Thanks |

The RAM clock is a multiple of the FSB clock also so lowering the RAM multiplier will give you more room to raise the CPU clock without the RAM becoming the limiting factor. 2) Raise the core voltage. Be very careful with this because you can fry your CPU if you overdo it. The BIOS will tell you what the safe limits are. |

Overclocking Intel E7500 cpu on a Asus P5Q board with PC64001066MHz Corsair ram
Ok, thanks for the reply, but I have a couple of more questions now.
In the BIOS/AI Tweaker, everything is set to Auto, except FSB,so I don't know what the default settings are or should be for the core voltage or the ram multiplier. Using CPU-Z on the CPU tab, the core speed is 2008MHz with a multiplier of 6, but does change up to 3673MHz with a multiplier of 11. The Bus speed is 334MHz, and the Rated FSB is 1335.8MHz Thanks General Schvantzkoph wrote: On Fri, 04 Sep 2009 14:59:51 -0700, Bob H wrote: My system has what is in the subject, and so far I have used the Asus AI tweaker to adjust the FSB upto 333MHz, which pushes the cpu frequency up from 2.9Ghz to 3.65Ghz.

Change from AUTO to manual and you should be able to set the other multipliers and voltages. |
