Hi all, well i have already managed to get 3.3GHz stable on my Q6600 B3 with my Intel x38 mobo and a decent air cooler with 1.415v. My idle temps vary from 34-40c and load doesnt seem to go above 60c ever. I would really like to get 3.4GHz out of this chip but as we all know B3's don't overclock as well as the newer G0's. I am aware of this but I would just like to know what is a safe Idle temp and what voltage I would need to get to 3.4. If I cannot get to 3.4GHz should I just consider getting a G0 or should I wait till the new Q9450 with 12MB cache? Many thanks.

You are right about the B3's not OCing as good.

Do me a favor and save your OC profile, then set everything on stock/auto, while keeping speedstep disabled and all the other processor options, like c1e, vanderpool, disable bit, and all the spread spectrum junk.

Then boot into windows and load core temp 0.96.1 and report the VID it shows. Then run prime or something and make sure that core temps VID doesnt fluctuate. CPUz is supposed to, not core temp.

We want to know the factory VID burnt into yer chip! Thats a fair indicator of abilities from what I can tell. I have a high volt one, 1.3125. Its horrid for OCing.

Hi,
Have you read the sticky ?

Those temps that you mentioned, are those the CPU temp or cores temp ? they are kind of low, what kind of decent air cooler you got ?

atm, you've set at 1.415v, you still can raise it but don't pass 1.5v.

Thankyou for the replies, my VID is awfully high at 1.3250v when im looking at it from an overclocked point of view in core temp. Thanks. I am starting to think I should justb get rid of the B3 and get a G0 though.

Yes and those temps are core temps. Right now they are 36 37 38 38.
March 26, 2008 3:32:44 PM

Oh, is the 1.415 in the bios, or what you see in windows? Either will turn out better than mine, lol, so we know your VID shouldnt be to bad! I need 1.4ish depending on droop for 3.2 stability.

I have a maximus formula that currently has its vcore at 1.38ish because there is no droop at all when Load Line Calibration is enabled! Yee haw! but at that point my b3 needs power to go higher. So 3.2 is its decent spot, which sucks.

I'll guess you have a 1.27ish VID one, but I hope its really low! Waiting for someone to have a really low VID q6600 of either stepping. Then again, who knows what else is factored into your temps and speed. Could be wrong temps and its really 90c!

So why not just list out yer components for all to see? it will help! We know you have a intel x38 mo bo, no ram, no power supply, no video card, a q6600 b3... no cooler, what programs you use to read those temps, what OS, blahblah...

I guess thats enough for now!!

Eeeeep! And yeah, thats the maximum VID is why its that high, because you are OC'd. When ya get the chance, just put things on auto, and make sure speedstep is off for sure! Then run it. It shouldnt change at that point, we hope!

Dont worry, you dont have a 1.3250 one! Thats the worse, and you are already out OCing one of em.

Oh, those idle temps seem rather low for a B3! You have speed step on so that it idles low?
March 26, 2008 4:32:03 PM

Nope, speedstep is always turned off, i am in quite a cold room :)  But I will check the VID on default later, thank you for your support!

Well, I can tell you that on my B3, 3.46 ghz is obtainable with 1.52 volts. But this depends on how much heat you want to tolerate. On my water system with Prime95 small FFTs, the coretemp reaches 80c (with just the CPU in the loop).

The B3 takes a beating but generates a lot of heat, even for water. If I were to push it (temps aside), I probably can manage 3.51 ghz with a vcore of 1.6. This will definately get it in the 90c area.

This is just to give you an idea of what to expect.
March 26, 2008 10:10:57 PM

Oh, I didnt say you couldnt get it. I had mine stable at 3.6, like you said, it was smoking! It's gonna get a test build in my maximus formula and on water. See how it does. Prolly start that tomorrow.

So far, all my final builds have failed for case reasons! Like I just spent several hours modding a antec 900 to take my external water cooling junk for a ultra. And of course it leaks, and to get to it, I have to tear it all apart, drain it, and such. Wow, that sucked! Would have been a tight fit, and would have worked, if it wouldnt have leaked!

Waaaahhh!!

So its back to sitting on my desk again. No case.

Ok, my VID in BIOS and Core temp seem to actually be 1.325v! I just don;t know how it ended up this high, i bought the CPU in June 2007 and I would have thought it might have been a G0, oh well. CPU-Z reports my voltage to be 1.39 something. If you were also wondering i am using an 8x multi.

My specs:

Gigabyte X38-DS5 Motherboard
4 GB (2x2 GB) of OCZ 800Mhz running at 825MHz 4-4-4-12 2t
OCZ 700w PSU
1x 8800GTX
Intel Core 2 Quad Q6600 B3 @ 3.3GHz 1.4125v (fully lapped)
Seagate 8MB 250GB Hard Drive, Seagate 320GB 16MB Hard Drive (I wish I had a raptor!!)
Creative XFi Extreme Gamer 7.1
ASUS Arctic square CPU cooler (lapped and on forced fan speed)
Gigabyte 3D Aurora Case (mmm...lots of room :) )

So I guess thats about it. Lupiron, might you just get a G0 if you continue to struggle? Im very near to doing that. Thanks.

I have a g0 1.2625 already, and a phenom 9500, and a b3 1.3125 VID one, and yeah, thats about right. I get 3.2 at 1.385 volts, and my g0 gets 3.6 at the same, lol. And is much cooler.

That sux that we both have such high VID b3's. A low VID one would be much better. But what can ya do?

And hey man, I have been using a pair of 250 gig sata laptop 2.5 inch 5400 rpm drives in raid zero for my comps, lol! Its much faster than a single one, though the big ones are 7200/16 meg ;)

I still dont think its giving you the right value. When next you get the chance, go back to auto voltages and run core temp again, and cpuz and anything else, DL HWMonitor if you dont have it, because you'll love the tool, and tell me their values, two in windows and you can somewhat guess the vid from the droop.

Do that and sell your working Q6600 on ebay.. I have the same VID and run hot @ 3.6 but h
I have a GO. Figure if it goes bad I will get another q6600, prices have come down. So far no problems.

Wonder the version of core temp that is being used! Did you get 0.96.1?
March 27, 2008 3:22:23 PM

I actually have Vista x64 so I have to use a hack of core temp to get my temps.
March 27, 2008 4:01:57 PM

download the latest 0.97.1. Vista x64 ready.
March 28, 2008 3:12:16 AM

Naw, just get the one I said, and Press f8 before windows boots, and selece driver enforcement disable. Thats the way to get all that junk to run. I hate driver enforcement! However, you have to do it each time you boot, or make a way around it.

All your other junk will work when you disable it, stuff that wouldnt run or install right because of the non signed drivers.
