    Default Overclocking core 2 duo with stock coolers

    Yesterday i had to change my mb as it was burned out. It was an Intel mb and so i never cud do OC.

    My new mb is Gigabyte GA-Eg41MF-US2H and it has good OC support.

    Now my question is how far i can OC wid my stock cooler.

    My current temperature readings from bios are around 36 degrees for cpu. (kinda confused y this is so low :S) and system temperature shows 50 degrees.

    My E5400 also shows 36-37 degree in normal mood which I have seen using HWinfo software...So I think your processor temp is absolutely perfect...Nothing 2 worry about d processors temp....

    If I OC my E7300 2.66GHz to around 3.0GHz, how much voltage should I increase? The current temp. is around 31-32C idle.

    ---------- Post added at 14:04 ---------- Previous post was at 14:01 ----------

    I OCed my CPU at first to 2.8 and then to 3.0GHz with stock cooler without increasing voltage. 2.8 worked fine [though didn't check the temp.], and 3.0 had issues with FIFA10 [the only game I play]. I then brought it down to stock frequency and it's working fine now.

    ok i have OCed my processor to 3 GHz.

    Screenshot is attached.

    Please comment on Vcore (whether it is too high; it seems high as it is set in auto in my bios) and temperature. I did not OC my memory as they are Twinmos and they stayed at 800 Mhz.

    Also shud i disable Intel speedstep. Many people in overclockers.net forum recommend it for OC but i m not sure.

    Use Coretemp or Realtemp to monitor core temperatures. I recommend using both, as one might show incorrect temperatures. So, run both and see if their readings mismatch. If it doesn't, you can run any one of those you prefer from the next time. I see you have HWmonitor, which is likely to do the job.

    For idle readings, stop all applications. Open task manager (right click takbar then click "task manager") and switch to performance tab. It should show CPU usage between 0-1%. Keep it like this for 10 minutes and note the readings from Coretemp/Realtemp.

    For load readings, download Intel Burn Test. Its a Linpack based program. Choose "Standard" stress level and set it to run "5 times". Choose to use "2 threads" and click "Start". While its running, see what maximum temperatures you get on each core. Note that down. Then post your temperature readings here. Idle temps tell only part of the story, load temp is the thing that matters.

    arre na ...... matha kharap ....... maximum voltage rating for my processort is 1.36V ...... er upore gelei risky.

    And ato voltage dorkar nai coz i cant go to 4GHz mark anyway wid my stock cooling.

    ok i will do the test.

    But my question is regarding voltage. It is good to keep as low voltage as possible to reduce heating while maintaining stability of the system. How can i measure the ideal voltage ?

    My CPU is permanently OC'd, from 2.83Ghz to 3.2Ghz with small increase in voltage (just in case). Running fine for the last 5 months. C2Q btw.

    And I don't think you can measure ideal voltage, just increase clocks and do tests, it should be apparent if higher voltage is needed, and of course don't go too high.

    ok i ran intel burn test at 3Ghz using 1.28V and temperatures rose to 78 degrees but all tests (5 times) finished fine. So it means system can be stable under load.

    Yes, its fine. Games should not exceed 70 degrees Celsius if IBT hits 78 degrees max. Congratulations, you've successfully overclocked your CPU. And about the voltage, keep it at stock, do not use "AUTO" as it will automatically increase the voltage to a crazy level. Do the voltage tweaking yourself. I don't think its even necessary before you pass the 3.5 GHz mark. Keep the voltage at stock, OC, and see if it is stable. If not, then up it by the smallest possible amount and try again.
