QUOTE(iBenQ @ Jan 2 2009, 10:32 AM) ive just bought myself asus P5Q3 i would like to know why i couldnt boot up to windows (im always having IRQL_NOT_LESS_OR_EQUAL BSOD message) when i overclocked my processor to 4ghz (500x8), at approximately 1.62v my old board p5k pro will give over voltage alarm when i try to set in bios more than 1.65v, but this mobo gives off the alarm at 1.6v... ive ignored the warning anyway and continued the startup... rams was at 1666, i thought it was ram problem... when i downclocked it to 1333, the problem is still the same... any ideas what is the prob? ps: it seems i have a fsb wall of 500mhz with q6600... will changing to 45nm procs give me a higher fsb wall? @@ 1. not all q6600 can boot at 4ghz 2. not all board can boot a quad at 500fsb, try use 445x9 instead 3. changing to 45nm will not give u extra FSB becasue mobo is limiting the quad fsb OC as well the main problem should come from the 500fsb, using 445x9 should solve your problem  |

QUOTE(iBenQ @ Jan 2 2009, 06:58 PM) hmmm.... no.1 is definitely no because my old board booted q6600 at 4ghz... ive even reached 4.1ghz... not to mention it was stable enough to do benchmark tests  no.2 is also no because i managed to boot up 3.5ghz, that is 500x7 and it was stable until i stress test it, in a few minutes i will experience hang which i can say the ram is to be blamed is there any other ideas? from what i know, the bsod i message suggests something to do with memory, but my ram is at 1333mhz @@ your stress failed because of mobo fsb limit. even u able to boot at 500fsb but hard to make it stable because is quadcore. but if u able to boot at 500fsb, there is a chance to make it stable, and 65nm is easier to make it stable at 500fsb than 45nm since it can take higher vtt. it depend much on your mobo capabilities |

QUOTE(iBenQ @ Jan 3 2009, 12:04 AM) oh ya... regarding vtt... i totally forgot about it hahaha... i set it to auto all the way, figuring the mobo can do its job, since i am stable at 1800mhz on auto ... when u leave it to auto, it will auto increase when u increase the fsb, this is not very healthy for 45nm i guess cause it will auto set it more than 1.4v vtt  |

QUOTE(iBenQ @ Jan 3 2009, 07:02 AM) 500x7 my pc will hang after roughly 10 minits like that, which again, i blame my ram, because my ram's been oc'ed from 1333 to 1666....everytime stress test, exactly at that time it will hang... havent tried stress testing at 1333 though... 445x9 not stable too, because my vcore is just 1.616 hahaha... i guess i need to up to 1.63 and above for it to be stable... one thing about my mobo is, when i stress test, instead of vdrooping, they increase the voltage instead... quite good oso hahahaha... btw im not using any water cooling, im just using air cooling... idle temp at 1.616v is 49~51c, while when i managed to stress 2 cores, the temp reading was 79c @@ with that vcore, it is not good with air cooling, processor will degrade very very soon... i dont see much q6600 can prime stable at 4ghz, 3d stable maybe possible.. if u wan to OC to high fsb for quadcore, gigabyte ep45-ud3p is the mobo to go |
