QUOTE(hazairi @ Oct 21 2009, 03:28 PM) Bro, i can see that your minimum temperature for E7400 is about 38-40 Celsius. Is your pc in an aircond room? Ya. Aircond room w TRUE. My minimum can only get 42 Celsius..     QUOTE(VT-Ten @ Oct 21 2009, 06:56 PM) yup, ram set to 667 and running on 343 FSB, the ram speed is already running at 428mhz. Get a good ram and oc.  Do you pump vDimm when you set FSB to 400? Guess it is due to lack of vDimm.  -pWs- |

thats the thing. borrowed a pair of perf rams, bump to 2.2vdimm and 1.5vcore, it still fails to post. even at 400x6 multi
 voltage for MCH and everything else also been set to max. therefore, i can only conclude that this mobo cant do 400 (at least for me) |

Ram timing? PL?
Do you manual set those? -pWs- |

Currently i'm still maintaining 3.74Ghz for my E7400.
Maybe i'll OC higher at the end of the year.. Just dont wanna decrease the lifespan.. |

QUOTE(mans @ Nov 2 2009, 05:59 PM) helo.. iam new about overclocking... try OC gradually..i want try to overclock my e7400 2.8ghz to 3.6ghz.. wut should i do ...try 3.2 Ghz first. U can do 320x10 or even lower multiplier. After that, try run Prime95 and see the stability. If got errors, U would want to higher the CPU voltage gradually until it reaches stability. If everything's ok, u can try to higher the speed and voltage..  |

on stock cooler.. it is safe to go up to 300x10.5 at stock Vcore.. provided yr PC able to boot up n remain stable at stock Vcore.. temperature will hit max 70°C when doing LinX stress..
about lifespan, tat's is very subjective IMO.. even if u dun OC, it might fail before its expected lifespan.. it all depends.. This post has been edited by farscope: Nov 3 2009, 01:31 AM |

Hi farscope, I already posted my statistic last time, well here it is again..
QUOTE(hazairi @ Jul 19 2009, 12:38 PM) 4Ghz@1.38v @3.72 Ghz my volt is 1.32 and the max tempreture running Prime95 is 73 celcius..Nice!! Your max temp only 68C? wow! watercooling? Anyway, here is my statistic of OC with my 7400 so far: Speed (Ghz) - Volt-Temp (cel)-Temp (kel)- Speed/Volt 3.49 1.24 65.00 338.00 2.814516129 3.56 1.27 67.00 340.00 2.803149606 3.67 1.29 70.00 343.00 2.84496124 3.72 1.32 73.00 346.00 2.818181818 It seems that the most optimum Speed per volt is at 3.67Ghz. |

FSB, if more than 3.5Ghz I set the multiplier to 10.5. My default memory speed is low, only 667Mhz, dats y have to set higher multiplier so that my RAM wont OC dat much.. |

tat's call Vdroop as mentioned before..
no wonder.. i was calculating wat multiplier u used for such odd clocks.. i m running at 333x10.5 @ 1.232V in cpu-z.. in fact, it is 1.27XV in bios..  tried 400 x 9 before, need 1.262V in cpuz.. and 1.31V in bios if not mistaken..  |

i use LinX instead of prime.. faster n hotter.. never tried Prime95 thou.. as long as it pass 1 hour LinX, it is good enuf for me..
i can boot at lower voltage.. but onli can stable at the voltage i mentioned previously.. |

QUOTE(hazairi @ Nov 3 2009, 01:47 AM) What about your tempreture? temperature wise.. on LinX load.. max 70°C on hot days, or 65/66°C at nite.. average 66~68°C hot days, or 61~63°C at nite.. idle is at 31~33°C depending on ambient.. normal 90~100% load (not LinX stress) is about 48~50°C.. |
