QUOTE(zuiichi @ Nov 16 2011, 01:02 PM) guys can comment on my settings? increase clock!! i suggest go by multi. if your chip is not lemon, then 3.6ghz is easy with voltage below 1.4 i prime95 around 1 hour with custom blend 2 minutes for each FFT. thanks. edited: resize photo  and also the NB freq. make it around 2.5Ghz and, reseat your gc. its running x1 now |

QUOTE(zuiichi @ Nov 16 2011, 01:58 PM) okay, first thing first, what is lemon chip? before unlocked, i can go up at 3.6, but after unlocked to get to this, i already increase vcore to 1.38Xv. oc the pcie wont change that.after i tell u this, do this advice still applies? sry, if what im asking is pretty obvious for u ppl.im still new. okay,i will reseat my gc now. will post new screenies later. thanks. Added on November 16, 2011, 3:13 pmi tried reseating my gc, still at x1. i tried overclocking pcie from 100mhz to 101mhz, still at x1 use cpu-z and gpu-z to check. both same result at x1. any ideas? clean the gold pins using eraser.see how lemon chip is the processor that performs below average..i currently using b55 3600Mhz with 1.37v. well, if cant make it 3.6Ghz, then depends on u the speed ok or not..kekeke |

QUOTE(cyberloner @ Nov 30 2011, 01:25 PM) those higher clock need water cooling wor.... i limit myself for until 1.45v only.but i cant really recall what the exact vcore for that. im on air cooling. ninja3i try and see... by the way what vcore? but the 8120 dont scale very well, 4.3Ghz hard to boot already. if yours the same, then its not my chip lemon then  |

QUOTE(cyberloner @ Nov 30 2011, 02:00 PM) i pump to 1.55 directly.... dun want waste time on oc... and might hurt the mosfets also. thats the part that i very sked.oc with this chip gonna cost u very much electric bill  8 core is damn more than enough  the power this chip draws is too much.. sked the mosfets cant take it. if thuban/deneb i dont really care... 1.55v for daily usage FTW |

QUOTE(cyberloner @ Nov 30 2011, 03:02 PM) i just use for 2 3 days only... running stock with lower vcore.... the turbo core for 1core how high eh? i also donno turbo core is there... no need oc kaw kaw already... 
manage to get this speed with "still safe vcore" but it wont last survive any benchmark i think. no time to oc now i guess my 8120 is the limit. increasing more vcore also wont help. yours also the same i think. just you luckier then me. got 300Mhz faster kekke |

QUOTE(cyberloner @ Nov 30 2011, 03:22 PM) that is 4900 wor... yeah.. this is 8150the 8120 is not so good. only 4.3 with this vcore. iirc, even i pour in more vcore, it wont boot with higher speed then this. now im having problem wth htt. i think the board/bios issue. 230 also hard to boot d |

@LBYuan
once u increase the HTT, not only the cpu speed will increase, HT link and ram speed also will increase together So try to lower down the multiplier of HT link and ram divider 1st. and increase the htt back and OC even its easy, you still need to have some knowledge. 1.7v is too much already. even 1.5v i wont recommend for long run. |

QUOTE(LBYuan @ Dec 13 2011, 08:35 AM) Sorry for the voltage typo dont confuse HTT with HT link Btw I reduced HTT from auto to x3 but it crashes also  Is it my mobo and processor doesn't support OC? HTT = bclck HT link = hyperstransport that connects the components of the mainboard already reduce the ram divider? just noticed your mainboard is nvidia 61. my nvdia 61 chipset cant go above 215Mhz HTT |

QUOTE(ah_khoo @ Jan 12 2012, 12:23 PM) no moolah for that bro... CNY comin liao... mosfets actively cooled? even 240 + 240 also got problem tamin d heat bro... as the temp already near the limit with this volt, i donno what will be if 1.45v btw, last time i read somewhere that said AMD purposely displaying lower temperature than the actual. u think? the temp reading correct or it shud be higher? hand job style ofkos. kekeke |

QUOTE(ah_khoo @ Jan 13 2012, 09:55 AM) yes sir, by a 6cm fan from stock intel p4 heatsink i inhereited from my bro. i mean the CPU temp. may i know the what is the reading for cpu sensor for 57c mobo sensor(any value also can)? difference is alot of just normal like before? which temp ur referrin to sir? i'd say mobo's cpu sensor is d most trustable one, core temp always reports lower temp for sure. if ur referrin to mobo temp as mosfets temp, i believe it's not. it could be t2 @ hwinfo64 as d intel p4 fan is labelled as opt fan2, & it's placed nearest to d mosfets cooler. i mite be wrong thou. |

QUOTE(antonio @ Jan 25 2012, 12:08 AM) more than 1800Mhz ram speed (to be exact 1840) , i need to use nearly 1.5v CPU-NB to allow stability.... not sure about your ram, but with regor/propus 1900Mhz is possible with acceptable vimc alsoI probably will run at lesser ram speed so that I can push the core speed and CPU-NB speed... Deneb's memory controller doesnt really can do high Mhz...1800 its probably the limit.... go grab a sempron!!! btw nice to see you back. |

QUOTE(Thrust @ Mar 17 2012, 11:02 AM) Actually is there any advantage by setting the Northbridge at 3GHz? The performance improvement is minimal right? not sure if all software scale like this.but i use winrar test and the improvement was good https://forum.lowyat.net/index.php?showtopi...post&p=43420977 |

QUOTE(meons @ Jul 11 2012, 09:47 AM) but new face prob come out... which 1 true both also wrong i think.. with non K version, you actually cant increase multiplier above the default.. with initial bios, you can increase the multiplier really high but its actually a bug.. you can check your performance gain, its 0. or even worse as turbo core is automatically off once u increase the "multi" correct me if im wrong |
