Q6600 @ 3.8ghz - But plenty BSOD's

You have to accept that your Q6600 isn't going to do 4Ghz with a reasonable amount of ccore ie <1.55. As mentioned earlier if you want a 4Ghz quad then look at a Q9550 or a Q9650. Both of which should do 4Ghz or a bit more if you go for the Q9650.
 
ok, believe me im happy, my old p5n-e sli board struggled 3ghz!

I guess i could up it to 1.5vcore and get 3.7ghz and settle with that. I get about 37fps in gta iv with it anyway and by the time i get my new gfx card 4ghz wont seem like a must.
 
I settled for 3.6ghz 1 year ago, any higher an it just was not stable. (I have a lapped tru so I dont think it was heat causing the problem)

It is still running fine today.

Cpu Core - 1.475v
DDR2 Volts - 1.875v
CPU VTT 1.2v = 1.23v
MCH 1.25v = 1.37v
ICH 1.05v - 1.15v
ICHIO 1.5v = 1.60v
DDR Ref +2%
CPU GTLREF both 67%

That would be because those boards weren't as easy to clock as a P35, if they would clock at all!

Mate it's your CPU run it at what ever voltage you want. Just be aware that many people consider 1.5/1.55vcore to be the limit/too much to run 24/7.

Personally id leave it at 3.6ghz, possibly even 3.4ghz due to the high volts required, ive clocked my q6600 to 3.8ghz, 8 hours + prime stable, with 1.50265 vcore in bios, 1.496 idle, 1.512 at load. I only clocked it that high to see if it was possible, normally run it at 3.6ghz theese days 1.4 vcore, didnt notice that much difference in gaming, only benchmarks. very few q6600's will do 4ghz, and the few that do are very low vid chips from certain production batches, run under water cooling or extreme air cooling, mine is a 1.2750 vid which is by no means a golden vid cpu and i cant see it going much further either tbh.
 
I would agree you are running some pretty high vcore, 3.6ghz would be a good clock for day - to - day use and I dout graphics wise you would notice any difference between 3.6ghz and 4ghz on the CPU

My Q6600 only to 3.3GHz and too scared to put it up more even my goal only to 3.4 GHz :(

Im sure you can get better, your motherboard is a pretty solid one, just follow the advice around the forums and keep an eye on your temps ;)

Heh, I got a new chip from the one in my sig, currently doing 3.65ghz @ 1.4v[/QOUTE]

Thats pretty sweet, you should be able to hit 3.9ghz-4ghz:D or so

what temperatures you get? If your ok you should be able to increase the voltage, also is your ram the same as mine (2x2gb platinum 1000mhz)? Set your ram to increase stability:

Advanced Chipset Settings (Memory Timings)
5-5-5-15-2T
Set the ddr2 voltage 2.1v

Thats if you havnt already setup these. Anyway what i learnt when overclocking is to not make big jumps, i.e going from 3ghz to 3.4ghz - raise your fsb say 10mhz and bump up the vcore, your bsods could be caused by the memory frequency, try and run it at 1:1 ratio
 
Hi toon mad and welcome to overclockers pull up a chair by the fire,say what sort of temps are you getting at 3.6/3.8 what batch cpu have you got?have a look at are Quad core data base if you havnt already

how can i get 3.8ghz which is what i wanted:confused:

Hey toon_mad,

just randomly read this thread! :p

I know what the problem is here, you have certain expectations of your hardware based on reading a few reviews and a few dozen forum posts and from the looks of things you seem mildly miffed/perplexed that your expectations haven't be met! :o

The bad news is sometimes overclocking is a bit like finding a golden ticket in millions of willy wonka chocolate bars, if you lucky or do lots of homework (or just plain rich) it is possible to obtain what we call "A Golden Sample", it is just a superior bit of silicon and yeilds the greatest overclock possible and no way can most other stepping/batches ever match. It may well be the case that your specific individual bit of silicon just ain't cut out for uBer MHz! :(

Haha now the good news is that your specific individual bit of silicon could be gOdly and due to incorrect set-up or user BIOS error your not letting the chip fly! The only way you can find out the truth about your Q6600 is to methodically and patiently work your way to testing different settings and configuration. You will need a good amount of knowledge on your BIOS and hardware to help speed you through trouble-shooting and masses of patience.

I personally enjoy the process of tweaking new hardware and pretty much start at minimum volts on everything and work my way up taking the chip as far as my knowledge and cooling will allow. You hit a few minor brick walls on the way and think thats it then you make some adjustments and your off again. Eventually you hit a real brick wall and no manner of voltage or tweaking will allow you to pass, also at this point you are running humunga volts through everything and not really at an ideal place for everyday use! :mad:

There is no right or wrong in your approach to when to quit and be happy with what you got, I deffo plug on to a point when its gets really really boring! :D

In your boots right now I would probably start again at about 3600MHz and see how low I can reduce the vCore to make it run stabley at that speed. Once your at 3600MHz just leave it there for a few days, chill out, run some tests, play some games and maybe do a bit more research on the settings other users have published (along with proper stability screens!) at 3800MHz and even 4GHz :eek:

Hope this helps a little and have fun! :)
 
Qoute removed :D

Very interesting;)

Well im sure there are other options i can set to get a higher overclock, 3.6ghz initially was my target - but seeing this board is able to do much greater, its crying out for more and more!

Ok so im at 3.6ghz now stable as hell, the only settings im stumped on is the cpu VTT which i think supplied the volts to the cpu, and then theres the cpugtlref which im assuming tells how much to supply. I think if i changed these, maybe along with the north bridge i could get 3.6ghz on a lower vcore. But its knowing the limits, and not one person on this site or anywhere else ive read seems to know a "safe" amount of vtt or gtlref to set.

This board like some others does suffer a fair bit of vdroop, but im pretty sure i could hit 3.8ghz with the same vcore or near enough as the 3.6ghz needs. It just seems to me though no matter what i change, its always going to need more volts, which is fine from a temperature point of view, but as recently spoke about is a huge amount of currents flying through!

What to do, what do?!?!
