First OC attempt Q6600 @ 3.6ghz 1.272v

I just wanted to share with you guys what I've done with my new computer.

I have the following:

Antec Nine Hundred with Zalman 120mm red led fans
Q6600 G0 with a Tuniq Tower with the fan blowing out the back of the case
Asus Maximus Formula SE
2 GB of Crucial Ballistix which I believe has D9 chips on it.
HD2900Pro which is slightly overclocked (which I will work on more later on)
Corsair HX620W

This has been my first attempt at overclocking and I've had some really good help from my friend off of these boards ..... Patriote.

Well I've been running Prime95 for 5 hours and 15 minutes. It's still running as I type this letter from when I took the screenshot.

I know I'm supposed to run it for longer but I'm never in my house when I'm not sleeping for more than about 6 hours. I want to be able to watch it and I can't do that while I'm sleeping. I think that if it's going on 5.5 hours and hasn't had an error at 100% then I should be completely stable when I'm playing my games and doing other stuff. Mind you this picture is while I'm on ventrilo, uploading the image through my FTP and browsing websites etc. So I think it's pretty damned stable.

Well here's the screenshot. Since this is my first time if you guys need any more information then please ask and I'll figure it out for you guys.

Oh yeah, also, I was having big vdrop+vdroop with the maximus but I enabled Loadline Calibration in the Bios and it completely went away. What I set in bios is maybe .01 off from what I have at 100% load.

All other voltages are set to auto because I don't know how to mess with them really.

I'm going to work on my memory now because I think that 3.6 should be good enough for me atm.

Then I'm going to overclock my GPU and see how much I can do to it. May get the HR-03/600 for it and put it on and see how that works.

Thanks for listening to my ran :)

Wow awesome low volt on that OC!
Is that one of the new week 38 chips?

I bought the motherboard from clubit.com about 11/7/07.

I hope that answers your questions.

He's asking about the CPU :P

WOW. I'm jealous :( :p:

Dang! Looking nice man!

Yah.... you are not relying on CPUZ to give you your vcore are you?

CPUZ has not reported correct vcore for well... at least 2 years...

Even if its 1.5volts 3.6 is a nice OC... TBH I do not know why I even bother overclocking this cpu :)

You can sync your RAM 1:1 because your FSB is also 400. Then start working on the timings, you should have no worries getting CAS 3 and tight timings, could even pull your subtimings down if you really want to tweak it. Auto Vcore is about 1.27v anyway and I doubt it would raise to over 1.3v unless you set it.

Set your RAM voltage manually to 2.1v before you try reduce timings, or overclock it.

Nice OC. I do believe that a 1:1 FSB:DRAM is more important than tight mem timings unless you are running highly specialized software like Seventeen or Bust

give the batch,give the batch............
i think i have an L738A in my house....maybe i`ll try it...

Oh yeah, I forgot.

I am using MX-2 thermal paste.

I'm sorry, I'm new to the OC'ing and I forgot to look at the batch before I installed the CPU.

1.41 does report right vcore. I have it set in bios manually and it's only .01 off from the cpu-z under 100% load.

I am thinking of dremeling the inside of the antec nine hundred for better cable routing. If I do I'll take the heatsink off and get the batch number, unless I can find it somewhere else.

Also, when I took it off of auto which was idling at 29 celcius at stock it was sitting at 1.2 so I have raised it to 1.285 and it's idling at 32-32-36-36.

please show another program such as speedfan
which is what you should be using anyways.

1.272 is damn near impossible for any cpu let alone a quad core.
sorry to say that but its true.
my 6600 ES was one of the few chips here to ever hit 3.6 at that low of voltage (3.6 @ 1.28v)
i just find it pretty hard to believe a quad doing that.

1.36v is close to the best i have seen yet.

there is always that golden cpu thats for sure, but even so..

prove the voltage with a DMM directly onto the board or with speedfan or some other program. cpu-z is not to be trusted (not totally atleast)

*edit* i do see your VID is 1.2v so... thats a VERY good VID which does show favor to you.
but anyways show us another program showing voltages or a dmm

lestat, my Q6600 can boot and play just fine @ 3,8GHz and 1,352V but for stability I gotta go at 1,384V... I could do 3,6GHz at about 1,3-1,32V so it may be possible, but I gotta say 1,27V is definetaly impressive!

I know his is a quad, but my E6850 can do that at 1.28v..

An E6850 also runs @ 3.0ghz at stock. The Q6600 runs @ 2.4ghz. So you can't really compare the two.

Wow sweet OC. Esspeicially on a quad. That voltage is stunning.

Tsaroth, you can check the Batch/FPO# on the box.. It also states the pack date.

Not sure if that makes much of a diff TBH.

Wow , what's the batch of this jem ?

congrats for this starting OC let see some 4000+ .


So the low vid is not a legend and seems to be more accurate then the simple batch code for the potential OC.

Don't these temp sound a little bit hot for only sub 1,3v ?

Oh man you're wrong. :P

My Q6600 L740A740 can do 3600mhz 1,288V and 3800mhz 1,39V.

http://www.pctunerup.com/up/results/...37_3600mhz.JPG

http://www.pctunerup.com/up/results/...1_3800139V.JPG

The problem with this chip is hot temperature, but I think to lapping it. :D

it seems those new batches got low VIDs and requiring low volts to achieve 3.6+ huh?

Yes. Mine is 1,2125V.
But my old G0 arrived @ 503mhz fsb instead this arrive only 485 under single stage. :(

So, this is a good cpu for daily :up: but bad cpu for overclock with freeze. :down:

These new low-Vid batches are awesome, mine does 4Ghz on 1.5, maybe even less.

I got a L737B ( had a nice discount on them) comming on my way.... hopes it turns out to be just likes these , cheers :up:

Tsaroth

Time to tell us how much Vcore you need to run at 9x425 and 9x445 then :)

Also what batch is this exactly? L737Bxxx (what's the xxx in your case?)

Not to be argumentative but it does actually. 1.2ghz overclock on stock voltage(Q6600) is way more impressive then a 600mhz overclock on stock voltage(E6850).

I saw a L737B560 in a store on friday.
Might go check out tomorrow if they still have it.

I have to say dude for a first time OC your results are amazing :toast: Very impressive, 3.6ghz on such low vcore

interesting stuff gentlemen.

i know alot of Q6600's were doing 3.6 @ around 1.36v but i didnt realise so many were doing that at lower voltages.

makes me want to cry given my 3210 (B5) need 1.52v to do 3.6ghz lol.

My new L726B has a 1.2 VID and dosent like to clock well. It will do 1.32 @3.6 but I can't keep it stable at all. Even if I up the vCore to 1.42..... Funny thing is I can boot @ 4.0 and do SPI1M. This chip got me 19K in 3d06 but I crashed when I tried to submit. Screen shot to show Validation.

JF if you saw that L723B560 you should have picked it up lol simply one of the best steppings ever ;):D

stepping is l737a806 pack date 10/17/07 :up:

L723... yes, but this one is a L737.
Think I'm gonna wait 10 more weeks, then I'll have a 747. :ROTF:

in the second line of the waffer`s numbers,can you tell me the last 2 digits?

i tell you nothing :shakes:
but i show you:D

i guess that you cannot look on the cpu right?

not at the moment in 2 weeks y buy a new cooler the i can check it!

hope d-tek fuzion or the enzo are the best for quads!
or install the nozzle kit in the d-tek!

omg 503 fsb is incredible!!!

My l740a740 can do 3600 with low voltage but 500 is a dream!!! :eek: :(

Thank you guys for all of your kind comments.

Now for the guys that question the vcore and cpu-z here is an additional screenshot with asus probe 2 which I don't know how good it is but there is also the newest version of speedfan in the screenshot as well.....

These images are fresh installs as of 5 minutes ago with no tweaking at all.

http://www.unholysyndicate.com/image...ionalproof.JPG

I will also get the batch code off the box when I get home tomorrow night. It's in my baby's room right now so I can't go in there and get it since he is sleeping.

Don't worry, I'll get it.

I think I am very lucky to get such a good chip.

I would push it to 4.0ghz but I do not have Water Cooling yet. I may get it in a while but right now it's not a top priority. I think my next endeavor is to get a new GPU cooler and push my 2900pro until it busts.

Could anyone tell me why all the voltages with asus probe are red? I have it set to auto. Should I go in and change those?

I think that asus probe is broken because the SB2 Voltage keeps jumping up to 5.5 and giving me an alarm. I don't understand half the :banana::banana::banana::banana: I'm looking at lol.

I'll learn more as I go though, of course with all my friend's help here on these boards.

Yes..... You are very lucky to get a chip like that. Especially being new to overclocking. I'm kinda hating you right now. :D

Ya I think Asus Probe is broken when u use Vista. That 5.5V issue happens to me too. I can only use it for temps.

I just got an L737B also. I am waiting on my new case and my pa120.3 to show up. I decided it was time for some other upgrades.... Let you guys know how it clocks hopefully some time next week. This looks promising so far.

Just got a L737A651 in the mail :D hope its a decent one.
Testing tommorow when the mb arrives = )

I picked up a L734A676 this afternoon. The L737B I talked about was gone.
Visited 3 other stores to check the batch #.
I saw 2x L736...., a L723.... and a L726...

Looks like mine isn't that bad.
Priming at 3600Mhz, 1.33V (bios), Easytune reads 1.31V, CPU-Z shows 1.296V.
VID : 1.2375V

Yeah looks good too :)

nice week of q66, up to 3800mhz plz

Up to 3800mhz any week as long as its G0 SLACR.

But L737 seems to be very good.

L737B075

I hope that helps you guys with what you were looking for.

I will up it when I get watercooling in the future. I don't have the balls to up it now. It's getting to 65 celcius when it's under load at 3600. I don't know if my HSF is mounted wrong or what, right now at what I consider idle I'm getting 33-33-37-37 so I don't know if that's bad or not. I'd love to have it under water but right now I have other priorities rofl.

Sigh...it takes me 1.5 volts under load to get 3.5 stable on my B3...:(

Hey just to let you guys know I also got a 37B batch.

Fortunately this quad can also hit 4ghz at about 1.45v and 3.6ghz is doable at stock volts. Haven't tried anything lower yet.

Oh and yes its hot but the cpu is extremely concave and not lapped. Also this mount isn't very good.

The exactly batch code is L737B062 pack date 10/31/07

I can get more of these exact cpu's but they're in canada.

so testing my cpu is finished!

new watercoolig is on order!

What is the critical data on the CPU?

L737A823..

It looks like a good chip, but you never know for sure untill you see the VID.. & then even a very low VID can scale different as an identical chip/VID.

So you'll need to test it ;)

I want to push it further on air.

Are my temps ok for air? I'm just wondering because with it at stock voltages and stock speed it's like 29-32 celcius and then when I bump it to 1.27 it's 33-33-37-37 and when I am running it at 100% with prime95 it's hovering around 57-57-60-60 maybe as high as 63.

Also all I've touched was the vcore and not any of the other voltages because I don't know what I'm doing yet.

Can I continue to raise the vcore and leave the other stuff at auto and go with that?

Also what increments should I go with to continue to raise it up. I'd like to see how high it can go.

I'll have to pull the computer out of the cubby it's in though and put it on a side table and go with that. I'm just not going to worry about getting WC yet.

Now I was planning on doing this.........

Basically up the vcore to 1.3 and then start upping the fsb until it's not stable.

I just don't know what temps are ok to have

and

how long do I REALLY have to prime for before it's considered 100% stable for the amount i use it (which is about 8-10 hours a day and that's being lofty, I primarily play games at night before I go to bed and on the weekends when I'm off)

I appreciate any input on this and if you guys want me to push it, help me out and I'll push it as far as I can. Eventually I'll probably lap the ICS and the HSF but not ATM.

Did test it, think vid was 1.275
Ran it 400 x 9 on air w/ 1.40 volts (pencil modded the resistor on the P5E)
It was proved stable with Othos running 12 hours.

Had problems with the ASUS P5E (rma'd for refund) so the chip is back in the package.

I got 3 new chips yesterday.

L737A832 10/18/07 1.20 vid
L737B293 11/02/07 1.32 vid
L738A976 11/19/07 1.25 vid

So far I have only tested the top CPU. It does 3.6@1.3 bios 1.29 w/droop on my 680i board. I have not done any stability testing, but I can do an xvid encode that takes 3 hours w/o crashing. I will do some further testing when work slows down.

Got my G0 (L731B158) rock stable at 3.6Ghz (9x400) on air for several weeks now with 1.32v (VID = 1.215). It tops out at 3.87 Ghz (1.4v) but i think this is mostly the board giving up (P5B Dlx). :D

My L737B does 8 x 450 @ 1,288V

Dude!! Got deep enough pockets?

Ok. I think i got a new good one.

L727B...priming now 3600Mhz @ 1.248v...I'll post some SS's later, at least 30min of prime95 for now, just to ensure minimum stability :)

Your temps are already pretty high for aircooling.
Upping the volts will increase temps even more.
You might increase the volts a notch (1.30-1.35V) and see if temps rise much.
Try to stay bellow 70°C.

So I was attempting to see how low my voltage can go while still staying stable at 3.6ghz.

So far this is the result. I tried 1.25 but that wasn't 100% stable.

Gonna keep trying to see if it can do sub 1.3v

http://service.futuremark.com/compare?3dm06=4110308

This is the first run with my ultras and my L737A832 10/18/07 1.20 vid

here is a cpu on first 4g try. Vcore is at 1.42 for this.

http://valid.x86-secret.com/show_oc.php?id=279889

impressive clock for a 680i motherboard :)

I can't even begin to think of raising my vcore that high because of my temps until I put it under water.

Right now I'm cool with 3.6ghz and it's running good. I'm on vacation this upcoming week and i'll be sitting around doing nothing much so I'll be able to prime and check for stability.

I'll let you guys know what's up with my proc in the near future.

Any experience on L736B??

This is a last one on my shop :D:D:D

Is good?

Any news from this front? Tsaroth has never posted the batch did he.

I'd assume that this is a L737B. That is the epitome of 65nm quad batches.

Blimey! the chips i'm seeing on this thread are golden! mines got a VID of 1.2375 but i can't hit 3.6 gaming stable without 1.425 vcore.

L745B007, Pack Date 01/02/2008 has 1.20 VID.
