dude.. manually tweak your ram.... follow the EPP timings as shown in CPU-Z

QUOTE(efilah @ May 13 2009, 08:46 AM) of course.i put it 5-5-5-15.i actually dont know what else should i tweak with the ram except the frequency speed n timing.i already set the voltage to 2.1v as stated by the manual.should actually be no problem reaching 1066MHz with the voltage.but cannot instead.aiseh.huhu hmm... using latest BIOS? have u tried tweaking the Performance Level (tRD)?....set u your tRFC to 40... not sure what's your RAM-mobo problem.. maybe ppl with the same mobo like you could give their opinion regarding this matter...

QUOTE(efilah @ May 14 2009, 03:04 AM) @hellokitty,wow, the temps are great.ur using water cooling? nice one. nice one there.. btw...yes! finally i know why. i had to disable T2 dispatch in bios.now i can reach over 1000MHz! im so happy.haha.  never though enabling t2 dispatch would make your ram unstable at high frequency(means @your RAM rated frequency)...i saw ppl oc their RAM without disabling the t2 dispatch and they can reach as high as 1200MHz on DFI mobos.. missed out that facts... seems that it didnt work well with your RAM.... Is it becoz you r using 4GB (2X2GB) RAM?... could u try experimenting using 2GB? and see if u could clock it higher with T2 dispatch enabled...

QUOTE(8tvt @ May 27 2009, 10:18 AM) normal..vNB.. no help also increase.. optimum @ that 400fsb.. bro... vFSB isnt the same as vNB... your mobo doesnt have vNB/vMCH adjustment....if above 408.. 1 core will failed after sometimes priming.. just accept the mobo limitation.. |

QUOTE(8tvt @ May 28 2009, 02:36 PM) sometimes a bit confuse on the naming scheme.. the ram timing also limited.. forgot edy what avail.. overvoltage/deovervoltage and another one.. mobo temp also cannot monitor.. QUOTE(iBenQ @ May 28 2009, 02:53 PM) what the hell is vFSB???? i have never heard of it @@ i only know vnb = vmch, vtt = termination voltage, pll, vcore, vdimm... vfsb = pll ka? if u google abit... vFSB refers to VTT or FSB termination voltage...@8tvt lack of vNB/vMCH adjustment option...that's why your mobo is limited to 400MHz FSB... and no wonder your mobo can't reach high FSB... the reason why u can reach 400MHz is your mobo officially support 400Mhz FSB... i have a friend using ga-p31ds3 mobo... P31 chip... it has vMCH adjust... i overclocked it.. reached 480MHz easy... but need to pump a lot of voltage to vMCH + adequete coolng...

QUOTE(sharkeer @ May 31 2009, 06:20 PM) guys. need opinion here. just bought q9450 c1 stepping. here is my oc detail. yup... thats normally ppl easily reach at 450FSB.... the problem is clocking the quad more than 450Mhz FSB is a challenge... despite low multiplier.fsb-450x8 = 3.6Ghz vcore = 1.28(cpuz) vtt = 1.26 mch core = 1.2 mch reference = 0.8 other on auto. is this wat normally c1 stepping can achieve? higher voltages, adequate cooling n numerous tweaks are needed to reach 500MHz FSB. I'm not saying it will rock stable at 500MHz FSB... in my case.. not stable... pass few LinX run only... This post has been edited by campsol2k: May 31 2009, 07:25 PM |

QUOTE(iBenQ @ May 31 2009, 11:29 PM) for my case 500fsb is not really a challenge, if its 500fsb alone... trying 500fsb on max multi, for my case is 9, is a damn big challenge... just getting me 500x9 took me massive tweakings, and i was able to pass only several super pi benchmarks before getting bsod... but 500x6, 500x7, 500x8 is not really hard for me  ... max fsb i've reached is 514fsb, either its my mobo fsb wall, or my proc fsb wall... need a dual core to find out @@ u must be applying a lot of vnb to get it stable...  i don't want to fry my mobo.. so don't want to apply too much vnb... thats the reason it hinders me to overclock the mobo n keep it stable at 500FSB. |

QUOTE(derek87 @ Jun 3 2009, 07:22 PM) Guys.. anyone knows how to judge the CPU VTT value if the settings are in percentage? for example +1.XXX%, +3.XXX%, +5.XXX% and so on... I guess like this ...for 45nm cpu the stock vtt is 1.1V so... if +17% means 1.1V X 1.17 = 1.287Vim currently clocking my Q9450 @ 3.333ghz, 1.25v , 417 x 8 on a jetway xblue p45. CPU VTT @ 17.XXX%.( i got the proc stable on IBT + prime, only with this value,lower than that, one or two cores will fail) This is the first time i came across with CPU VTT(FSB termination) using %percentage for settings... it was always 1.4,1.5 shown on the bios.. really pengsan.. Thanks guys. |

QUOTE(derek87 @ Jun 3 2009, 08:21 PM) hmm.. i also tot so... but... the last option is 120%.. possible? lol... possible... my asus mobo can go upto 1.9V... adjustment upto 2.4V for your jetway mobo is unnecessary...imo QUOTE(derek87) it was always 1.4,1.5 shown on the bios.. which voltage u were referring to?

QUOTE(ToddStarz @ Jun 4 2009, 06:16 PM) guys, now im using q9550 + ep43-ds3l + ccf @3.4ghz.. i wanna know if it worth the upgrade to buy ep45 ud3r + megahalem to try and hit 4 ghz.. im gaming on 1920x1080 reso with gtx 285.. i got extra cash at the moment so thinking of changing the mobo.. I think changing your mobo is just unnecessary.... your mobo has sufficient overclocking options... if u clock it right.. with proper fsb:ram ratio... reaching the 4GHz on your mobo isn't a myth... |

QUOTE(efilah @ Jun 4 2009, 08:42 PM) actually bro, that mobo is not very good for overclocking. i heard other users of that mobo also complain about OC hmm...  i had one before.so hard to reach 400MHz even for E8400  of course overclocking option is sufficient but the capability isn't. or maybe because im just noob in OC haha   In the end i changed to P45 mobo which is as stated in my signature. i guess u r right... since u told that the mobo isnt a good overclocker... guess TodStarz might consider changing the mobo after all. nway, thx 4 the info...This post has been edited by campsol2k: Jun 4 2009, 08:56 PM |

QUOTE(sharkeer @ Jun 5 2009, 08:39 PM) pass prime for 6 hours. ibt pass 10 loops. not enough... OCCT test? 10 loops IBT arent enough....run your windows in diagnostic mode to free up more ram...then run IBT for 1~2 hour also run OCCT test for 1 hour... 3dmark few loops... trust me...passing prime95 for few hours doesnt make your PC 100% stable...

QUOTE(derek87 @ Jun 5 2009, 09:52 PM) IBT cannot be completely trusted. 8mins = 40hours of prime95. lol... Quite true in fact, but just not PERFECT. why people always get the wrong idea that 8 mins IBT equals to 40 hours Prime95...? 4me its not equal at all...it doesnt matter u ran prime95 for 40 hours.. u must complete the OCCT test at least 1 hour for each test set(small,medium n large) and IBT test (max ram) at least 1 hour... including other tests(prime95, etc) of course... thats the common rule.... B4 IBT was released to public/overclockers community... i use OCCT as my main tester instead of prime95..... believe it or not i ran 7 hours prime95 but failed OCCT test within 15 minutes... the test methodolgy made by cstkl is just to pinpoint which voltages are needed be increased...thus reduce time and effort... to stabilize your overclocked setting... without having too many tester... i think its a good guide.. but i'm not sure about the accuracy of the relationship between each voltage and each custom prime95 torture test... neither pictures nor overclocking logs are provided by cstkl in the guide..

I do agree with u...
i've experienced myself... clock 3.9GHz Q9550... multi 8.5 vtt 1.28, vcore 1.275, vnb 1.26 vmem 2.1 for example... i've -passed 38 run LinX(approx 10 minutes) then crashed -passed Prime95-cstkl Test 1 and Test 2 but crashed in Test 3 specifically for FFT size 448K.. ran custom test again specific for FFT 448.. then crashed b4 1st interations was completed... -passed OCCT small set for 1 hour... So 8 mins IBT isnt equal to 40 hours Prime95... its a flawed statement... This post has been edited by campsol2k: Jun 6 2009, 07:06 PM |

QUOTE(sharkeer @ Jun 6 2009, 09:53 PM) i agree with u. ibt really stress the processor. i'm afraid it will damage the processor if running for 1 hour or more. even with adequate cooling. That's an excuse not to run LinPack for 1 hour and nonsense thinking... if u kept everything cool below recommended limits ie VRMs, mobo, CPU, NB, SB... ur system won't die easily ..the effect of increasing your voltage too high and too much exceed recommended/max voltages that will permanently damage your hardware because of electromigration... even with adequete cooling...
