I guarantee you cannot complete 32M calculations of super Pi at that low of a voltage. My Q6600 has a VID of 1.225. I could boot and run at the same voltage but it wouldn't pass any real benchmarks.Quote:

Well being rock stable on 3.6GHz and 1.28v isn't really impossible and I'm sure he can do it, considering the fact that he has a VERY rare chip with a VID of 1.200v. Actually, never seen a second one with that kind of VID.Quote:

I'm personally less lucky, but still my chip can do 3.6GHz rock stable on 1.32v, but my board is limiting me a little so I'm keeping it as in my sign below :)
And tbh, considering 32M SuperPi stable is a little too soon. Errors can pop out even after 3H of Small FTT's on Prime95. In my opinion, 8H+ and more can be considered stable.
That's a bit of a blanket statement...... my vcore drops to 1.28 at times too.Quote:

Try loosening up the RAM timings for now so that you know it's not that cheap ram holding you back whilst you up the FSB. Also, try running a 1:1 divider as well.Quote:

Chances are, the Maximus will overvolt the CPU @ 3000. You may want to lower voltage manually in bios. My board went to 1.3v on auto but was prime stable with 1.17v (1.16 load) @ 3000.Quote:

i hope its a good chip :)
i will post more results later because i have to go to work now
what OS do xtreme users prefer? XP64 or Vista64?
also, im using 4 instances of SP2004 with Large FFT and priority of 8 for stress testing. is that good enough? i tried to run 4 instances of Prime95 and it gave me a virtual memory error. im sure im missing something.
Vista 64:up:

It happens that I was perhaps overvolting my CPU unnecessarily. I was setting it to 1.4200v on my BIOS. :shrug: As for today, I'm running my Q6600 G0 VID 1.2375v at 3000 MHz with stock voltage. So, that statement seems to be true for me, but I guess it also depends on your motherboard and CPU batch.
Oh, by the way, it seems the stock voltage on my board if I set it to "Normal" it's the same as the VID. My board's got a horrible vDroop, so voltages are 1.184v at idle, and 1.152v at full load after eight hours of Prime95, according to CPU-Z. My temperatures are 32 ºC (average for all cores) at idle, and 48 ºC at full load. There is a picture of my setup on my signature.
I'll be testing more MHz in some days, maybe perhaps this weekend.
Have fun, and good luck!
I can barely make mine boot into Windows at 9x333 stable (1.450V vcore) on my previous P5K Deluxe rev. 1.00G (went defected). Now, my RMA from Asus got here, which is rev. 1.01G and I can reach 9x333 easily with stock vcore and stable, too. I can honestly say the new revision makes a big difference on OCing my Q6600 (at least in my case here). I'm very happy...
alright ppl. here are my results of oc on my q6600 with maximus formula. i also ran 4 instances of orthos previous night which ran for about 20+ odd hours before i stopped it. will post those pictures later.
Did you mount your TRUE properly? Maybe try lapping it? From the difference of temps on cores I think it has a VERY concave surface... Around 60C is fairly normal on the settings you're using, but 77C is wicked, you definitely need to fix this.
Wow thank you everyone for your posts! I'm not gonna OC yet for a while. Though I think it could be nice to prepare this soon.
hey everyone, finally put everything together last night and ran Orthos at stock and everything was good so i slowly upped it to 3 GHz (334x9) and it runs fine.
im testing at 3.1 (345x9 with 4:5 divider on stock vcore) and had to drop a divider because my mem is only rated at DDR1000.
is it worth upgrading to DDR1066 mem or should i just save $50? i was going to get this kit:
http://www.newegg.com/Product/Produc...82E16820231166
i would upload pics of 3 GHz, but thats just a baby OC so far :)
The sticks you have should do 1066 no problem.
Go for 9x400 stable first, then start on the RAM...
I have those same sticks and with some pushing they do 1066
wow. go for 3.6 right away? :)Quote:

http://i48.photobucket.com/albums/f2...2976/zzzzz.jpg
not stable at all... but not a bad screen shot either :p:
Well, you could walk your way up slowly to 3.6 GHz.Quote:

The 4:5 would let you run the RAM at stock and also run a 400 FSB for 9x400
If you want, you could give the NB some more juice and go for 8x450 with that same divider you'd be looking at 1125 MHz RAM, in which case you might want to upgrade :D
I still haven't found any RAM that will go past 1100 MHz stable on my Maximus Formula. I've had ReaperX PC28000 2x2 GB, Mushkin Redline PC28000 2x2 and G.Skills like yours. Next on the way are the Corsair Dominators 2x2 GB PC28500. Hopefully they get to where I want them to go.
I didn't notice, are you on vista? is that why you want 2x2gb not 4x1 cos i reckon ocz flex would go that high I've had 2x1 stable @1280 for a month on maximus formulaQuote:

i hear thatthe G0 stepping is "designed" for a 333 fsb. does this mean people wont see any decrease in the life of the a q6600 g0 if they run at 333. i have one that im currently running stock. i started reading this thread and notice alot of talk about VID. im not sure what mine is, ill check when i get home. but on my p35-ds3l bios the "normal" voltage for the cpu us 1.3,so thats probably the VID.
question. how low do u guys think i can go on vcore to get stock speed if the vcore is actually 1.3
ques 2, is 333x9 really putting any more stress on the q6600 or is it a really safe overclock. i plan on using this system for at least 5-6 years.
ques 3 - my system loaded windows at 400x8 at 1.3. temps were at 36-37 idle. didnt bother testing/priming benchmarking but im pretty sure it would be stable cause many peeps here have them stable at higher speeds. would this lower the useful life of the cpu??
1. you can check your VID using Core Temp found here: http://www.softpedia.com/get/Windows...ore-Temp.shtmlQuote:

2. any kind of OCing is stressing the CPU, but you have to watch the temperature that is a result of OCing. if you keep it at a safe level, then you should have no problems
3. even though you were able to load windows, you should still test your cpu and memory at full load to see if its stable.
so your saying the tempurture itself is what is hurting the cpu in terms of its longevity??. as long as i can get an overclock to work at the same or very close to the same temps as stock, (around 32-35c idle) there should be little to no harm done?
i would think that running a CPU at a high temp for its life will degrade the chip quicker.
sorry for the noob question, but what does bumping the NB voltage do? its the memory controller right? right now im testing 400x9 (1:1) at 1.45 vcore and running 2 instances of Orthos with 2 CPUs each. stable for 8 minutes so far......Quote:
Originally Posted by zlojack

Well, I think those temps are a tad high...but it depends on what your ambients are.
As to bumping the NB, it gives more stability for raising the FSB to higher frequency.
what temps should i be trying to avoid? the highest it goes is 78C
also, what is the max i can bump the NB voltage to? im probably just going to bump it .1v for now and see how it goes. so far im 30 mins stable with 400x9 (1:1) @ 1.425v :)
EDIT: ah, core 2 crapped out after 45 mins. back to the drawing board.
this is my opinion...
80C is too hot
70C is max I would tolerate for benching, but
60-65C is max I would run for long periods, and
60C is max I would run for 24/7 overclock
71C is the thermal spec at processorfinder
and take these guidelines with a grain of salt... everyone has their own limits.
Mine goes to max ~71c with 3.9GHz and 1.535Vcore when playing games. I would not go higher than that.
I don't care what people say, you need 1.40-1.42v to run the Q6600 completely stable. Prime 95 is overkill, but for a short time 30 minutes or less will give you some insight into stability.
When you guys post your vcore, make sure it's CPU-Z or some other program other than your bios setting. My MSI undervolts significantly from what the bios says the CPU is running at.
I would say that anything over 75C for long periods is not a good idea. The Intel stock cooler idles in the 50's.
I can run my quad core at 1.225v all day at 3.2GHz but it could crash at any time and has, but is quite stable. Getting to 3.6Ghz takes 1.4v
My opinions are only for air cooling, not water cooling, but I think it may be similar. Water cooling just allows 4.0Ghz or more with 1.5v +
So even though it could crash at any time, you say it's stable?:confused:Quote:

And by that I mean 8-24 hours of continuous priming, not 30 minutes which doesn't give you any insight on stability, since the pc migh aswell reboot after 3 hours of testing...Quote:

The CPU's life length is determined by temps, vcore voltage and ppl voltage. Just don't go above official intel specifics and it's all fine.
My 1st post here ;) been here for sometimes for information and now I contribute something back....tks guy for all the good info.
XP64 Q6600 L740B154 at 4Ghz 1.525Vcore 3DMK06.
Watercooling system, ambience temp around 29-30 degrees.

Got my Q6600 yesterday. Overclocks very well.
The Weird thing is..for 3.6GHz I only need 1.35Vcore to be stable. On 3.9GHz I need 1.54Vcore. I can get it up to 4GHz but it's way too hot and need about 1.6Vcore. Also my cooler is unlapped so the temperature is not good. Max is about 71c when playing games.

and what is the Purpose of the Execute Disable Bit?
and what they have to do with OCing could they be limitng me to the 3.8G that i'm stuck at?
thanks.
I made a poor statement. I could run games at 1.35v all day without ever crashing. The operating system would never crash. Super Pi would crash over 8M and Prime 95 would crash after 15 minutes. I didn't realize a VID of 1.225v was considered high. Considering an earlier post of the "GO" stepping at 1.20 was only seen a handful of times.
I thought I've seen u state somewhere that ur VID is 1.3v, if that's not the case the I am sorry I must have confused you with another user. But with a nice VID of 1.225v you must be really unlucky with the batch to have such poor voltage to performance results. I've tested my L737B393 on 3.6GHz (9x400) on 1.32v and it's stable for a few hours of priming. Only problems are temps and cheap motherboard, which refuses to run 3.6GHz with 8x multiplayer cuz it can't handle so much juice. That's why for now I'm staying on the settings visible in my sig.
My vid is 1.3 :(. I was spiing just before @ 4.4ghz but its a little un-stable. Im priming now @ 4.1, 1.7v and its nearly finished the OCCT stability test. I should be able to squeeze more out of this yet.
Are you sure you have a Quad6600?!Quote:

ok, so i finally got some nerve and OCed the Q just a bit. its only 333x9. hardware moniter reports vcore at 1.22 (set at 1.25 in bios)..i read that a v drop is kinda normal..idle temp stayed the same at 33-34c.
dled core temp and my VID is indeed 1.3 :(
not really much of a story since everyone else is doing 3.6+ but its great for what i need it for. hearing everyones stories here made me feel bad about not getting more out of my chip..
one question, is it important at all to use a solid integer memory multiplier like 2 or 3 instead of 2.x and 3.x.. i think im at 2.4 right now to get 800 at 1.8v. are decimal multipliers more stressful on the northbridge?? thanks for any info.
i read a review somewhere that the x38 does not oc any better than a p35. only real advantage is the sli or crossfire abilities. they used an intel reference x38 board in the review though so its possible that a partner company can make it more OCable. the review basically said if your not gonna sli or crossfile, the p35 will serve you fine. they tested mem performance and everythign and they are both equal if you take a margin of variability into account. its kinda the same as the nforce 680 and 650 chipsets, one is made for sli the other,while capable at 8x, is not "optimized" for true 16x sli. too bad the p35 only does 4x and so is not even worth it.Quote:

I can run my Q6600 @ 4GHz with 1.475v all day long but it crashes too. Just being able to run all day at a certain clock doesn't make it stable. I can play videos, music and light gaming but if I Fold or Prime or try Encoding it'll crash/lock/reboot/blow up instantly!Quote:

Hi all,
Seems like I have hit a wall with my Q6600 and am just a wee bit disappointed. I have the Giga-byte GA-x38-DS4 with Q6600 G0 water cooled setup, 4GB G.skill PC2-8000. Nvidia 8800 GTS 640MB also water cooled.
So currently I have the board running at 9x400 with the bios voltage set to 1.65(shows 1.6 under load in CPUZ). I have a water cooling setup and its showing load temps around 57-62C
Here are the rest of the settings in the bios.
FSB 400
PCI 100
Memory at 2.00B
5-5-5-15 G.skill 2x2GB
voltages
CPU voltage: 1.65
DDR voltage: +0.2
(g)MCH: +0.15
FSB voltage: +0.1
loadline calibration: disabled
rest of the settings are on Auto/Normal
even with these settings I am not 100% stable in Prime95.
I can really only get stable at around 3.4GHz with 378x9 and 1.5v in bios
any ideas?
try ddr voltage at +.3. i think the specs are 2.0v to 2.1, yours might be at the end of that spectrum.
OK that has definately made the 3.6GHz setting way more stable. Thanks for that tip.
I'll try out the higher speed options later tonight to see if I can get 3.8 stable enough to boot windows.

... and why do you run loadline calib disabled ? this is the only feature that gives you a more stable clock at a lower voltage...
I have my q6600 ROCK SOLID STABLE at 3.6, 1.33v no vdroop control. I have run OCCT for hours on end and have spent several hundred hours encoding video with it like that. P95 has run over night like this with no problem. I also have C1E enabled so it drops to a 6x multiplier when not under load. I have some water cooling (nothing too special) and I run in the mid 40's under load and upper 20,s at idle. I have never had the OS crash on me. I have had the same installation of XP since December when I bought the mother board. And I have a 1.225 VID chip too. :shrug:Quote:

Hi guys i will buy this cpu and i have a noob question :( who know what is the memory chip on these supertalent modules : T8UB2GC5 (from usa) and T800B1GC4. if it is micron or others
I thought there would be a flurry of results based on all the price drops recently. Picked one up at Frys for $190. My first Quad since price/performance were never aligned above the $200 mark.
Decided to take a break from the conga line of air coolers crossing my bench recently and just go for a simple water kit the Swiftech H20-220 Compact. I thought about breaking out my old more robust water gear but I remember getting tired of wrestling with hoses when I last had a water loop on my bench. This kit's reservoir is in the rad and the pump is in the block. Super simple mounting as well. But I digress ...
L744B144 pack date 2/26/08. Initially testing looked good with low voltage, but core 0 kept crapping out while other cores Primed happily. Is that common? It didn't help that my Blood Iron is droopier than ever.
Here's a shot of OCCT at the tail end of the default 1-hour run. Good starting point?
http://img208.imageshack.us/img208/8...occtrg4.th.jpg
yay finally got my quad stable at 3.6ghz, 1.5475v set in bios, 1.44v real :D
temps running OCCT cpu test 75-75-72-72
mult 8x
fsb 450
mch voltage +0,2v
fsb voltage +0,2v
That's great!!! Thats about where my voltage is at with mine at 3.6Ghz too. I have tried to get it stable above that and it seems I have to push too much voltage to make it worth it. Since we have the same boards I imagine you will be limited like me unless you want to do a volt mod.
Anyway, glad to hear you got it to 3.6Ghz.

That's some high temps, around 10C too hot for my taste... And it's on AIR, it's gonna get even worse when summer comes, I would so something about it if you don't want to fry the chip.Quote:

That's some high ambient temps... Well yeah, it propably won't fry, but I don't think it's gonna last a long time running 24/7 like this.
I found that uses 1:1 dividers provides no better overclocking than using memory dividers. Every "GO" should be able to hit 3.6Ghz, after that it takes big voltage or what I like to call brute force to gain a stable overclock over 3.6Ghz.
My highest Core hit 68C for a brief moment of online gaming.
Has anybody hit anything above 3.6Ghz stable on air? 3.6 seems to be the wall for air cooling. I'm not saying you can't push it higher. I'm talking about 24x7 stable overclocks.
Alot of people post overclocks that they've achieved but they forget to mention that they are not 24x7 overclocks.
It looks like the 45nm will allow 4Ghz+ overclocks on air.
I run mine 24/7 at 3.7Ghz and I am selling it.Quote:

Here is 3.8 on air running WCG 24/7. P5K Premium, 2x1gb Team Xtreem, TRUE with 2 Yate Loon medium speed fans in push/pull, Antec P182. Just took this shot a few minutes ago. About 65f ambient. Notice it has been up for 18 days. I got this processor from another member who was able to get to 4.0 with water.Quote:

Don't waste a lot of time with prime, but here is 2 hours from a previous shot.

I have my Q6600 at 3.8GHz with 1.49Vcore 24/7.. I had it at 3.9GHz earlier but it was too hot. I don't care at all if it is 24/7 PRIME stable... what matters to me is that it is at least stable for games and so on.. I've had my computer on for 3 days now without reboot and I have been playing games for several hours. Enough for me.. I don't think I'd ever stress the CPU 100% for 24 hours ;)Quote:

Well you are in for some nasty suprises then if you think a 32mb PI is a reference for a rig to being stable :shakes:Quote:

Why should 1.5 volts be hot ? each CPU is different, some pump out more heat at 1.35 volts than some at 1.5 volts... if he stresses it and it runs below eg 65°C (that's my safe limit some go further) no worries then... your CPU core hits 68°C during gaming that's 70 plus under Prime or co... it's all about ambient temps, airflow, cooler, IHS, CPU luck ,... there's more to heat then just voltages or VIDs...
But to each his own...
Hi,
I wonder how stable are these OCs of the Q6600, and if they are good enough for a work environment?
Is it stable enough to be OCed say by an admin, and used by a normal user, who doesn't understand OCing, and who does heavy production work (100% CPU most of the time), and needs his machine to be reliable?
I am also wondering (though in the same context), what type of coolers work for what speed? Can I do 3.2Ghz on air, and with which heat sinks? and from what speed would I need a liquid system? And is a liquid cooled PC safe to be given to a normal user?
almost all q6600 and xeon x3220's do 3.2ghz on stock voltage with stock heatsink or any aftermarket heatsink.. it's after that it get's harder and requires more juice... Most can do 3.8-4.0ghz on a good water system, but unless the person you're selling it to has some knowledge of watercooling, in which case he probaly wouldnt be buying a prebuild system, don't sell someone a watercooling system, they can be a real hassle..
stability is pretty subjective, if it was for a customer or something I probaly wouldnt send it off before it had done OCCT cpu for like 48 hours, mine passed 12 hours OCCT so I'm pretty confident it's stable
Indeed. My cores doesn't go above 65c when I'm playing games for a long time. And that is totally acceptable as long as it is stable. I don't care if I would kill my CPU in a year because I'm upgrading then anyway. Each to his own.. :)Quote:

It gets a bit hot, but as long as it's stable. I don't think it'll be as hot playing games anyway.
'06 daily score:
http://xs125.xs.to/xs125/08141/06daily202.jpg.xs.jpg
I gained 2.3k on the cpu score and 2k on the overall score by going from a dual-core to a quad-core at the same clockspeed.
It did 3.2ghz on stock vcore (occt 30min stable) but needed 1.368 for 3.4ghz to be completely stable (VID of 1.2750). Doing the vdroop mod on the mobo really helped.
I have change from air to water and back with cpu,s from 2 diff mb,s and never seen a cpu need more volts when going from water to air so if your cpu is stable at 3.8G with 1.4V on water it will be stable at 1.4V at 3.8G on air it your heatsink can get that heat out. I ran the first q6600 I had at 3.8G and 1.725V for 68C 1hour OCCT on air. When I put it under water it did not clock any better and still needed the same volts just running 20C cooler.Quote:

im old school, still running dual orthos with 2 cores assigned to each :)
im currently running it again with a lower NB voltage to see if its still stable. i need to reseat my Big Typhoon for some better temps. when i try for 3.6, it goes up to 73C!
I have a question about degradetion of the Q6600, Did anyone encounter it after long term OCing?
does the only way to know degradation is if i need more voltage to operate on same frequencies and be stable?
unless you are pumping insane volts into your chip, i think you will upgrade by the time you notice degradation. as long as temps are good, the chip should live a happy life :)Quote:

When I see vcore between 1.55v-1.7v with water cooling, I know it's stable and will work. I admire watercooling but I'm too scared to try it. It takes a lot of expertise to do watercooling better than the best air cooling solution.Quote:

We all have different motherboard but seem to be hitting the same wall regardless of motherboard. The P35's seem to handle the Q6600 the best.
Running at 1.5v or higher is a waste of energy and provides diminished returns. But this is extreme forums so the sky is the limit.
I'm looking forward to 45nm Quad Cores which should provide 4.0Ghz with air.
Motherboards are controling how far they go. With Q6600 and the Max formula my max overclock was 3900mhz@1.5V at 60+C. Now same ram, gup, cooling and cpu with warmer ambient (spring) and coretemp vers. with the striker II Formula 4G@1.55V is easy at 50C and I am trying to get 4.1G stable. 100mhz+ more and 10C cooler with the same parts. I move cpus around all the time so this is not a seating problem but constantly 10c or more diff.Quote:

take a look at the following. just got them this morning after running a good 23hours.Quote:

here's the link for my previous unlapped conditions.
