Guys,i have a situation....  My E2160(M0 stepping) doesnt seem to be overclock well..... My rig: E2160--->3.04Ghz(8x380)--->not suppose to be 3.4Ghz???  Ip35-E bios 14 IP35-E has one 8-pin 12V atx(i'm using 4-pin),one 4-pin molex connecter,one 24-pin connecter I found that if i unplug 4-pin molex connecter i cant even POST at (9x340=3060). If i plug-in then stable at 340x9 @ 380x8 at 1.50V(YES!!!! 1.50V  ) I just want to know is my PSU limit my OC? or CPU FSB wall? i'm using cheap cheap icute 450w PSU. Got 8800GT 512mb(720/1800/2006)+-100w?  2 HDDs,1 DVD R/W... I think not the RAM limit coz i cant get 9x380mhz but can stable at 8x380mhz.1:1 ratio ofcoz. |

QUOTE(Bigblock @ Mar 4 2008, 04:42 PM) Bro 380*8 is 3040Ghz  Actually ure supposed to use the 8pin connector for power mah? Last time boards 4 pin better u use a real power 450 W at least sure can power ure board... If not CPU limit then sure can go 9x380=3.42Ghz....  I just want to know is 4-pin or 8-pin will affect OC? Or no enough power will affect OC?  |

QUOTE(flatfinger @ Mar 4 2008, 05:05 PM) it stated 3.4GHz because it still read ur multiplier as x9.... 4pin atx can be use at 8pin eps...but it will give a little instability... that's y the 4 pin molex can help u patch up voltage if needed...better just connect it... 1.5v is ur selecting voltage in bios??or by plugin the 4pin molex make it 1.5v??? which mean u cannot do nothing I set it in bios,not stable below 1.5V  9x380mhz is what i want but i only get 8x380 or 9x340.  if i un-plug 4-pin molex 1.5v also not stable.Does any one who use ip35-e also facing the same problem?  |

QUOTE(flatfinger @ Mar 4 2008, 05:13 PM) just plug in the 4 pin molex... for 9x380...u will need more than 1.5v to stable lor....1.5v not enough...only can boot but will failed orthos for sure... 1.5V no enough? i thought 1.5V is consider too high already for a C2D bas proc... most c2D only need 1.35/1.45V to reach 3.4ghz.  |

Damn...Internet down.  QUOTE(a1098113 @ Mar 4 2008, 05:43 PM) @all hold on your horses guys.. thanks commanders under my legion, flattie, techfrix for guiding this fellas.. but there are few points i would like to state 1. For the Abit ip35-e, i dont recommend a 4 pin PSU, coz its unstable. Play with 8 pins.
2.BIOS 14 is alright. so use it. and dont dream of 3.4GHz yet. Start your first benchmark at 3.2Ghz. Listen, 3.4Ghz is not easy, even for my self. And Funnyface, we are not talking about Conroes here, we are talking about Allendales with a stock speed of 1.6-1.8Ghz, so u will at least need 1.48V(for the normal procs) to be running at 3.4Ghz, attempting the 8* of course. But if u do go at 9*, then maybe... but very unlikely. That is what i mean  . thanks for the info  a1098113 QUOTE(a1098113 @ Mar 4 2008, 05:43 PM) And Funnyface, we are not talking about Conroes here, we are talking about Allendales with a stock speed of 1.6-1.8Ghz, so u will at least need 1.48V(for the normal procs) to be running at 3.4Ghz, attempting the 8* of course.

Man...change PSU still can pump up any mhz... 340x9=3060,Vcore 1.5-1.58v--->not stable 350x9=3150,vcore 1.54-1.58v--->not stable 360x9=3240,Vcore 1.56-1.58v--->not stable 370x9=3330,Vcore 1.58-1.58v--->not stable 380x8=3040,Vcore 1.5V--->SUPER STABLE  Setup: e2160,M0 step + Abit IP35-E bios 14 + Cosair value 667mhz 1gb x2 Still dont know where goes wrong. Interesting issue is THE STABILITY DOES NOT IMPROVE AFTER CERTAIN SPEED EVEN VCORE INCREASE for my case(3040mhz) Stability does not follow: 3060>3150>3240>3330 But follow: 3060=3150=3240=3330??? |

QUOTE(a1098113 @ Mar 8 2008, 11:19 PM) yeah it looks like we need to address the issue.. sorry for the long wait.. guys. Funnyface.. u r pumping too much voltage for such low speeds. YOu will end up burning your proc.. and calm down dude. Biggie, try just using 8* Looks like clock speed is the main factor here. We are all learning guys. If stock cooler definitely...I am using Zalman CNPS9700,keep it cool full load at 59C Vcore 1.58V.  QUOTE @funnyface
Try like mine 335*9 =3015Ghz at lower Vcore bro...u should be able to run...at least with mem devider... i have no problem running 335*9, max is 337x9=3040.Once over that,not stable for any extra voltage. thx for the alert @a1098113 now running 380x8 with Vcore 1.47V |
