As promised...
A couple other things I should mention. The NB and SB heatsinks have been removed, cleaned and AS Ceramique was applied. There is a small 50 MM fan on the NB. I have recently put a heatsink on the VRMs. My board has had the vdroop pencil mod done on it.

Just checking, the vdroop is the difference between what is set in the BIOS and what is reported in windows?

As long as I can remember having PCI-e on auto is trusting the board to keep it locked to 100mhz. Forcing to 101, gives me piece of mind that the PCI-e isnt way overclocked or holding back an OC.Quote:

I think the higher FSB relaxes some of the chipset timings.
Yea pulling CPU-Z is the easy part... now make it prime stable :D
http://3dxtreme.net/other/Q6600%20L7...4.0suicide.jpg
Ugh, Small FFTs failed after 3 mins on Core1 @462x8, 1.48v
Tuning GTLs only caused it to BSOD under Prime...
1.36v 3.6GHz = 1.4xv 3.7GHz? :shrug:
I find that especilly on my old P5K-E I would need to up the PCI-E frequency to get a stable clock at anything over 3.7ghz ish... So would run it at around 105 - 110 depending on how much over I was going... this doesnt seem to be so much of an issue on my P5Q-DLX but I run it at a locked 105mhz just in case..
Thats an impressive FSB for that board a quad :DQuote:

BTW THX for setting me straight with the vdrop and vdroop :)
Just set 101 or 102 Mhz for PCI-e. No sense damaging your GPU.
Well it looks like 3.84 might be possible with BIOS 1102. Didn't let it run long though.
http://3dxtreme.net/other/Q6600%20L7.../3840-1102.jpg
nice overclock.
My other Q6600 which is now air cooled in my "wife's PC" had one weak core. I could run 3.6 @ 1.35v prime stable, but not much above that was stable. The 4th core would always fail. I could bench 3.85ish even with it. Some chips just have a weak core and no matter how much vcore you throw at it, there is nothing gonna get you stable.Quote:

Probably not... the Q9550 has a fair chance of 4GHz though.
Cheapest on the net -
http://www.ewiz.com/detail.php?p=Q95...3568450bc1376a
$316 for Q9550 doesn't really seem worth it when the Q6600s are $180 and can do 3.6+ Ghz. I see you already have a 3.6Ghz CPU anyways.
Q9550 and Q9650 but the latter is far to expensive to be worth spending the money.Quote:

I'm thinking of hunting for a 1.2000/1.2125/1.2250 VID Q6600 and try to run it at 4Ghz for daily use instead of paying loads for a Q9550...
I'm just wondering if it's worth the effort.. Since i'm running mine at 3.6 without any probs..
From my experience with taking a 1.3250, 1.2625, and 1.2000 to 4.0 GHz, they all scale about the same after ~3.6GHz with respect to voltage. You need a good motherboard more than anything.Quote:

I notice this chip takes 1.65v BIOS to run 4.0GHz stable. Although it is less than the 1.2625VID, it's only by .05v. The 1.325VID made it to 4.0GHz, but not at a voltage I felt like sustaining for as long as it took to do some benchmarks. I think it was something like 1.75 or 1.8v. I really don't know if it was stable.
What I would recommend is to save your money and buy a 45nm that will do 4GHz at a lower voltage for 24/7.
So, to answer your question, IMHO I don't think it would be worth it for you. Besides running benchmarks, there is no noticeable performance gain for me with a q6600 from 3.6 to 4.0GHz.
That being said, if you watch the classifieds close enough over at OCF(or anywhere else) you can pick up a 1.2000VID for $160.00 like I did. Hehe.
Holy :banana::banana::banana::banana:, what kind of volts are u guys feedin ur quads :shocked:
Mine never even saw 1,5V and that's under phase.. got an ultra-low-Vid-hot-as-hell CPU though.. it's at 260W with 1,45V already :rolleyes:
Your are lucky man :)Quote:

Well Jcool, perhaps you can share some of your settings etc. It may well be possible, but not with my Board/BIOS as far as I've been able to tweak it. My system won't run prime for more than a second or two at 3.8GHz with 1.45v, although it will boot up and game. 24Hrs stable needs 1.525v. Haven't even tried Rosetta or F@H. So I can forget about 4.0GHz at that voltage.
I must have 1.65v with this 1.2000VID chip to run 4.0GHz stable overnight. Ambient climbed to 32deg the next day, so I didn't bother going for 24hrs.
He is under Phase Change cooling.
"""""""Well Jcool, perhaps you can share some of your settings, Mine never even saw 1,5V and that's under phase"""""
OR NOW
Case & Cooling: hybrid SS/water cooling in LianLi PC201
Does it really matter what Kind of cooling he has? It shouldn't make a difference should it? A chip is going to take a certain amount of voltage to reach a certain Overclock regardless of what's cooling it. The difference is going to be how hot it runs per voltage added.
There is going to come a point, if you go high enough, where the chip would temp out without the extreme cooling to get it there. But, to say that one person can do 4GHz at a lower voltage because he's using phase change as opposed to Liquid or air, I just don't know about that. He certainly may run cooler, but to change thermal and electron transfer effects to the point where a noticably lower voltage could be applied to stabilize the same overclock, I must say I've never experienced that.
No offense intended here guys, but by that rationale, I should be able to get far more per volt out of this chip under my water loop than I was ever able to get out of it with my TRUE. That is just not the case at all.
Maybe I misunderstood your posts JCool and Beast, and you'll have to enlighten me. Does the voltage required go down exponentially with each 10 degrees you go below zero or something?
Cooling does matter as the cooler the CPU is the less voltage is usually needed to hit same GHZ as others with poorer cooling.
Many times chips under chilling and phase change can use less voltage maybe 1.45 as opposed to 1.55-1.60 for some others with similar VID chips.
HEAT is a killer in OCing.
Ok, I think I was just confused in the wording.
Honestly though, back to my previous point. I have experienced absolutely no difference in the amount of voltage it takes to OC this Q66, when changing from an air setup to a quality water setup. The only thing I notice is that my 3.6GHz overclock runs alot cooler now. You must have to go pretty damn low into sub zero territory to reap those kinds of reduced voltage rewards.
Cetain chips the lucky ones with same VID some can use less volts then others in same builds and cooling.
Example: I had a Opteron 146 @ 3.2ghz with only 1.46v Air Cooled and a friend bought from same batch and same cooling, same mobo and ram and PSU as me, but he could never do 3.0ghz no matter what voltage he used.
That was just an example a true one at that for similar batches and builds.
You will see many ppl using less volts then other of similar batches and on better cooling.
Or to word it better would be HIGHER ghz at Same Voltage as Some at 1.50v can only get say 4.0ghz where as Colder Cooling = 1.50v = 4.5ghz .. example is all and truthful at that in many cases.
My god!
what kind of chip can do 4.1 with only 1.456v? o_o
That's just insane

I always had a hard time doing that with even 1,45V, and I did have some badass wc setup.
Again, the reason must lie in the difference of CPUs. Some draw more amperes than others, with the low Vid chips usually being the ones with more leak currents, hence more heat dump than the high vid chips. Meaning that my Q6600 may well be eating the same amount of power at 1,45V as some high vid CPUs at 1,55-1,6V which is why you can run that kind of voltage in the first place.
If I would feed mine 1,6V my phase unit would go down and the PSU'd probably explode :ROTF: :rolleyes:
Which is why I won't do it, problem is FSB anyway (stupid mobo won't go higher) :shakes:
Old ones, L8XX sucks :rolleyes:Quote:

Just remember guys, if you want 24/7 settings the old rule still applies.. max 1,45/1,5/1,55V air/water/phase.
Some might go beyond that, but I wouldn't give more than 1,6V 24/7 no matter what.
I definitely need to learn how to lap that monster... It really might be what you're saying.. Temps are way too high =(Quote:

Far too many people believe the TRUE is better than the TRU aka Thermalright Ultra 120. In theory the TRUE should be better with the addition of two additional heatpipes (6) over the older TRU with four. However, Frostytech.com has said for a long time that TRUE fails to maintain full contact with the CPU because of the bowing that occurrs with the mounting of two additional heatpipes. Still the TRUE performs quite well even with on 25% contact on the CPU's in many cases. Here are the cooling numbers from Frosty Tech. http://www.frostytech.com/articlevie...id=2303&page=5
I have two Thermalright Ultra 120's myself. One runs on my Q6600 and the wall is 3.6Ghz on this chip. You need brute force (very high voltage 1.5v++) to climb well above 3.6Ghz. I certainly am impressed by some of the overclocks many of you have achieved.
My only question is wheather there will be a new 45nm CPU Quad introduced on the 775 chipset before the Nehalem chips and new chipsets appear. I'm hopeful Intel has one final 45nm Quad core yet to be released that can achieve 4.0Ghz on modest voltage 1.45v or lower. :D

I have read it al over the next about such a topic and it has been debated many times and has been proven in instances more then just say 1 that really cold temps can allow for a lessor voltage needed then on AIR cooling.
The only way to know for 100% is LNC your CPU to find out.... :)
I'd have to agree with this. Can't prove beyond a reasonable doubt it was the temperature, but last time I was at 4GHz(which is the only time my CPU has ever been anywhere near 60Deg) I did have alot of BSOD's. Whereas, with only slightly less voltage, 3.8GHz was stable as anything at mid 50deg core temperatures on RealTemp. Mine is also a 1.2000VID.Quote:

And when I mean stable, I don't mean intelburntest stable :P I'm loving this program its crazy.
This thread is looooong, very informative and interesting.
Here's my experience
I have a true q6600 vid 1.275
I can prime95 9x400 @ 3,600 all day,
but 8x450 @ 3,600 will fail on 1 core but keep going and going on the other 3
so I say, well what does that really mean?
and I guess, well we haven't crashed,
it's just for 4 cores to hit 100% full load I need more vcore
but with a vid of 1.275 it's more vcore than i can cool, a bad vcore/temp ratio
450 FSB gives me much better DDR2 bandwidth than 400
so i choose 458 fsb as my 24/7 'cause i don't bsod or crash
whatever works i guess
some have even said they uninstalled prime after 1 day
'cause everything else was stable and would pass, only prime would fail
well some, most actually are now saying they've uninstalled or disregard their failed IntelBurnTest runs
haha well what's now different from me and others disregarding our failed prime95 runs?
I can happily say I have been running like this for at least 10 months now and I'm glad I chose to disregard the unrealistic and over the top demands placed on the cpu by prime95.
I rather have stability for sure then a few mhz faster. You want over the top? IBT is over the top compared to OCCT and prime 95.
but what is stability or what does it mean to you?
to me stability is running all my apps and games without any ANY problems to report EVER, thank you.
IBT and Prime95 are over the top imho
Orthos Blend Test for at least 12hrs is good for me, but i doing longer on this CPU for the fun of it and right now i am at 15hrs 19min and still going and i may shut her down at 16hrs... maybe.
i got intel Q6600 G0 last year i hit 3.2 ghz on air run 24 hrs stable with prime95 after one year my cpu wont stable all setting same anyone know how to fix this should i reseat heatsink put new AS5 or get new water cool system i want my cpu hit 3.2 ghz again
I already posted in your thread no need to keep posting same question in other threads... :)
Maybe its degraded.Quote:

*snip* Look below...
You might want to take a glance at the Q6600 thread in the Intel section, since this wouldn't really be considered extreme overclocking. The Overclocking Q6600 thread has helped many people including myself get my cpu past 3.4GHz
So I got one of these Q6600 G0 CPUs lately and I've been thinking of OCing it to 3.6GHz. This is proving to be quite a trip as right now I have vcore set to 1.48750 in bios and it's still unstable. I have put 400x9 and I also have the newest F11 bios for GA-P35-DS3P rev 1.0. Before OCing more I had a stable OC at 3.2 (356x9, vcore 1.3850 in bios). Any ideas or help? Should I just ramp up the vcore a little bit more?

Syvere, that's a tough board to overclock the quads on. Take the nb sink off and put some good TIM in there and then use a small fan on the sink after. If you have some small sinks for the mosfets use them. Sometimes I just use old sb sinks and cut them into tiny bits to use for mosfet sinks on cheap boards. How much are your fsb and mch overvoltage control set at?

All measured via DMM, different PSU = different GTL values. I needed above vNB and VTT for DDR1200, this chip can run this on stock vNB and 1.3v VTT.
I'm on old OCZ PowerStream 520W.
Really nice OC, but not LV WR ;)
I've seen 2 or 3 similar CPUs in the German HWluxx forums, incidentially on the same mobo. The DFI LT/UT P35 rock.. they're even better than my X38 except the X38 clocks 4x1gb a bit better.
Now try how low you can go with 4Ghz, mine needs around 1,42V (GTL disabled tho :wasntme: )
Well real vcore with dmulti I was getting 1.26v under load in Prime95 and to be honest I never saw a single screenshot of under 1.29vcore Prime95 10hrs blend for 3600Mhz and Q6600 so I'm pretty sure 1.28v is WR or close to it :up:Quote:

My cpu prime stable at 8x460MHz but would like to know if someone can post some info on bios setup for FSB @ 470MHz or over. Trying to find out what's max FSB at x8 multi for the cpu, need like 1.5V NB for current setup.
Tnx. :wave:
With all due respect to you all, prime is :banana::banana::banana::banana:, pure :banana::banana::banana::banana:, been prime stable @ 3.6 ghz for 48 h running and running a single try at intelburntest 1.6 about 5-10 or 15-20 min crashed the app (or shows calc errors if you chose to turn off error detecting), therefore i laugh on ur faces when i see prime shots which is a joke.
But i imagine ur comps would also be intelburntest stable if ur vdroop is excellent, mine is not, drops 0.05v even with Load Line Calibration (P5K PRO)
This kiddie attitude will get you pretty far... I've posted numerous times that there is NO bulletproof test version... you can have linpack stability yet crash on prime, OCCT or a 3dmark,... this is why I suggest you to run numerous apps and verify then... and the best stability is daily usage... if it doesn't cap out or produce errors or acts weird it's good enough...Quote:

Get your act together and clear ya head... then come back or stay where ya were at...
If im in a hurry I run prime for 30mins, if not 2 hours max...Quote:

It seems weird you would bother leaving your computer running for 48 hours under full load, what an electricity bill you must have.
And as leeghoofd said, what a stupid attitude, not to mention primes fairly often the standard for stability tests. But really the most stable computer is one that doesnt crash for daily use, and no single test can 100% guarentee that.
My apologies, it was not my intention to start a flame war, i never said there was ever a bulletproof test.
All i'm trying to say is that prime is fully replaced by intelburntest since it does a good job upping the heat by many degree from prime, and the vdropp is dropped even further than prime, so why would you even bother use prime? That at least is my opinion.
EDIT:
And maybe i should elaborate my previous post, indeed i stress tested prime 48h, but after the countless failed intebultests, i ran prime again, maybe a couple hours only. to my surprise it was fully stable, and then i reran intelburntest, it failed. And to ensure it, i did that one more time, same results, prime succeeded, intelburntest failed. To get it stable i raised my vcore, both was then stable.
I have used prime for quite some time, maybe just like you, it's standard to test your overclocked computer with prime just as you say. But now something better is out, and seeing people taking prime-shots and with the experience i had with intelburntest for overclocking (not a single computer build with it has been crashing even once) makes me mad. And before with prime-stable overclocks, sometimes but not always it just crashed and i had to start looking at voltages and and temps all over.
Well Prime eg gives you the feature to test CPU alone... when you want eg to determine "stable" Vcore, thing I don't like about prime is that it doesn't stop if the clock isn't "stable". this is one of the reasons I use OCCT for CPU, then RAM and then Mix test. Afterwards a Linpack 10 run test (maximum memory) and then some benchmarks... then it's off to folding and daily abuse... I like linpack as it can be used as a brief test but I see some run 100 plus runs, which is kindda hard on ya hardware as in daily usage you don't push it that hard... and AgentGod also states it is best used under 64bit OS... which not everyone has...
you can have your opinion; freedom of speech also is valid here, but try to bring it a bit softer lol... also bear in mind not all clockers here are english (like me) so sometimes we take it the wrong way...
Well after reading my first post again i can understand it was a slap in the face for some ^^
I'm not trying to flame either, but can I ask a quick question. If IBT is the best at find instability, they why are their a number of people on the IBT thread stating they can pass the IBT test but fail at priming? Here are just a few posts I found with a quick scan:Quote:

You can add me to that list as well.Quote:

hey ive got a l750a966 its fine upto 3.2 but then it gets really juicey have to nearly pump 1.57v to squeeze 3.6 out of her but im on water and temps dont go above 60c so fine anyone else have the same batch as mine VID 1.325v had it post a 4ghz once but never sinse :(
QFT. :up:Quote:

Yes, it's in the Intel section.
UPDATE after a month:
My Quad right now has never failed while crunching @ 1.32v... ?????? Maybe one day when I get water I'll give 3.8GHz another whirl.
So trying to decide between the ASUS P5Q Deluxe and the BIOSTAR TPower I45 I'm leaning towards the Biostar just because Biostars treated me well in the past vs. the hell I had with Asus. But is there any other boards in particular that handle this chip really well I've decided it's the one I'm going to go with.
The IP45 is great with Wolfies and high FSB, but the 4-phase power isn't good for quads.
People keep saying this but even with older IP35 boards and such they seemed to do all right?Quote:

Hot indeed. Hey I love how IBT doesn't determine the multiplier you set. For a while I was like .. . "HOLY CRAP 4.2GHz. NOMOMOMON" :p:
79C Isn't hot for 1.52v... My 1.2125v VID chip gets to ~101C @ 1.36v on IBT... probably why I get instability at those clocks.
I guess we are on the same boat, and to add the pain, mine cannot stable @ 1.57v, failed after prime 1~2 hour.Quote:

Case-Antec 900 [painted flat black on inside, reversed HDs, and hidden cable mods done....Im a neat freak about cables....should all look like nothing is plugged in]
Mobo-EVGA 750i sli FTW edition [Im not a triple GPU type of person and neither is she]
CPU-Intel Q6600 [with go stepping]
CPU cooler- Zalman 9700nt
GPU- 2 x PNY 8800gt [had one already and the egg had them for 110$]
RAM- 2 x 2gig Corsair dominator DDR2 1066mhz [yes with the nifty fan]
HD- Seagate 7200.11 speed 3g/ps 32meg buffer 640 gig
LG bluray/dvd/cdburner
PSU- Mushkin 650w modular sli ready
Vista 64bit ultimate [for access to more ram later]
all viewed on her 24" LG monitor[she already had]
Ordered it all friday10/10....3 day garaunteed UPS shipping....Ill be getting it....according to UPS most current data....10/16 on thursday....and thats with Newegg proccessing my order and shipping it by sunday nite.....wonder if theyll give me 50% off my next pizza like dominoes for late delivery?
Now...Im interested in getting her a 3.4-3.6 ghz OC on that proc and keeping her there...maybe a tweak to the ram to 1200 and a mild GPU OC. She isnt a "power user" by any means and the machine is certainly MUCH more than she will use for some time [She plays WoW and the Sims....also Command and Conquer] so she will be solid for some time to come.
Ive no experience with this proccessor...but...Im confident the aircooling setup given with that case and CPU fan should do the deal....will be installing the NB fan on the nice large sink that comes with the MOBO...
Anyone else have any experiences with this mobo/cpu combination?
I think it should do fine no?
My own rig Im ashamed to discuss....went the full DDR3[finished my build 2 months ago] route BEFORE really looking into the next gen stuff...cost me a fortune....and will be obsolete in a few months....its one thing to go from solid midrange performer to still solid midrange and an entirely different thing to go from top of the line to ....mid....ahhh well....I SHOULDVE WAITED ON MINE!!!!!!!! lol
j/k....I crush everything I play so meh...
@mikael116, should be no problem hitting 3.6ghz according to some of the reviews.
@Mick64 is that a 45C load at 4.2Ghz?
LOL my bad I see now the test was stopped.
I thinking of trying to overclock my Q6600 to 4.2GHz for some quick benchmarking.
On a scale of 1 to 10 how dangerous do u think it would be?
DW about temps, they will be fine.
Also what the max Vtt and PLL volts I can use?
Personally, I wouldn't bother unless you have it under water to help keep it stable through a bench. @ 470x9 = 4.23Ghz under water my 1.2000VID ran ridiculously hot (75-80degC. @ 1.7125v). It was just barely stable enough to do a full suite of benches. Forget about Prime or IBT.
I see that you've done 4.1 on your IFX-14. How did that go for you?
Sry, I use a Gigabyte X48T. I don't know much about Vtt and PLL. My MCHvoltage was +.3v and FSBvoltage was +.35v.
Adjusting the MCH and CPU skews and manually setting each set to 50ps was the only way to stabilize the overclock at those voltages.
Anyone know what Newegg is shipping, Week? How do the new ones OC?
Well I did it in Winter and have a look at the temps :DQuote:

I'm not to worried about the temps.
Also my mobo won't let my vcore go above 1.7v in BIOS, so about 1.635v in windows.
I just ordered the one I mentioned above.....they are shipping GO steppingQuote:

From everything Ive seen it looks like an agile OCer in general...anything that on average hits a 1.2ghz OC without any longevity issues on AIR...aye...nice
I do kinda wish they had the 12meg L2 cache though...itll be interesting to see just how much of a performance difference[I already know itll be alot but still] this build will have versus my own computer.
Case- Thermaltake Armour Plus LCS[yeah I took the easy way out but Ive since replaced some parts....never quite liked the circular cpu block contact patch....!]
CPU- Intel Q9550[oc to 3.8 stable and staying there for now! and just couldnt bring myself to pop for the xtreme lines]
MOBO- EVGA 790i SLI FTW
GPU- 2x EVGA 9800gx2 [had one....wanted 2..second was on sale for 300$ at the time and really not worth the cost to "upgrade" to the 280s]
RAM- 4 x 2 gig Corsair Dominator 1800mhz DDR3 14400 speed ram [with the nifty fan but no OC....yet...]
HD- 300 gig WD Velociraptor[OS and progs] and 1tb Seagate 7200.11 w/ 3gps and 32meg buffer[storage]
LG bluray/dvd/cdburner[gotta love the performance and price!]
PSU- Corsair 1000w modular
Vista 64bit ultimate [yes I get all my 8 gigs heheh]
Obviously....I KNOW Ill out perform what I build her[it crushes games/tasks....both from power and weight....FREAKING HEAVY!!!]...but...if this chip performs as well as Ive been hearing...and heavily researching recntly...then...I may start using it in more builds for friends instead of always suggesting the intel q9450/9550 chips as much...
Yea the Q9x50 just arent cost effective. I build all PCs for people now with Q6600s. I've had a few, have a E8500 @ 4.4 right now. But I miss my quad. Im interested in finding out what week you get and how it's OCs. I've heard the newer ones arent very good overclockers/Quote:
