Hey everyone,

Just looking to see what some other people used for there settings when overclocking their Q6600.
Specifficaly I'm looking for those who overclocked to 3.0Ghz and 3.2Ghz.
So please post up what you changed (voltage, fsb..etc)

Thanks,

More about : q6600 settings

Run coretemp and post your VID here and I can tell you roughly what kind of voltage you'd need for 3.0-3.2 ghz. It's really dependent on your specific chip, for example mine runs at 3.0ghz on auto voltage and stable 3.0ghz with the smallest voltage boost I can give it, but that number will be different for your CPU.
March 24, 2008 3:50:20 PM

Nice, but you may want to post your system specs, power supply, Mobo, ram, etc! That always helps since they are all so different, and all OC differently.

Then place your settings on factory defaults, but disable speed step in the bios! Put VCore on auto and boot into windows and load core temp 0.96.1 and list the VID and stepping/revision of your quad, please?

CPU multi to x 8, FSB to 400, North Bridge to 1.4. For now, try a VCore of 1.4500, CPU Pll Voltage to 1.6, Front side bus voltage to 1.55ish.

Thats 3.2.

Now remember, that voltage there is gonna be a bit high, depending on your quad, but once you get it boot stable, you can run tests, and then lower the voltage respectively.

That FSB of 400 will also let you run your ddr2 800 in sync. Dont know what kind of ram you have, but its usually 800.

Prolly can guesstimate better when you list your comp info. If you happen to have a p5k-e, kewl! If its a 680i, have fun!!

Stop posting short ones, you get em in there before I do!!

Hehe!
March 24, 2008 3:51:46 PM

LOL, on auto voltages? No kidding? Thats because it over volts the cpu, lol. Most of the time! When you wanna OC high on factory voltages, gotta not be on auto, hehe!

Every chip and mobo are a little different so using the exact settings from someone elses set up might prove unstable for you.

That being said... I good way to start is to open core temp and see what VID your processor has. It will have a good chance running at that voltage up to 3.0ghz. If it fails prime 95.25, then up the voltage one notch untill stable. Don't forget to keep an eye on temperatures while doing this.

My northbridge is set at the lowest setting( don't remember what)

Same for the southbridge

Lock pci express to 100

For the hell of it my b3 q6600 is stable @ 334FSB, 1.2625volts bios, 1.232 actual(cpu-z) at idle.

This setup is on a P5K Deluxe with "line Calibration" enabled for "v-droop"

What we really wanna see is the VID value from coretemp, but the AC freezer 7 should easily be ok for 3.2ghz (and probably up to 3.6). The really important info is the VID value, mobo, ram, and power supply. I will say it seems you picked some of the better components out there so you should be good to go. I will admit I know little about the Corsair PS lines, but if it's as good as thier memory it should be ok for what you're pushing. BTW, what case and how many fans are you running?

I actually have that mobo, but I'm scared of the 4pin CPU power connector so I haven't dropped my q6600 in it for testing yet. Supposedly a great board and so far I had no issues with my initial testing on it; e2160 to 3.2hgz.
March 24, 2008 5:53:02 PM

What's wrong with the 4pin CPU power connector? It'll melt or something?
March 24, 2008 6:01:26 PM

Yep. After I purchased it, I read a review of it melting under an overclocked q6600. There is a reason they went to 8pin adaptors ya know. It's still a massively popular board and it isn't like I've read this happening outside that review.

I've just been kicking myself for not getting the Abit p35 @ $60 after MIR. I went with the more costly gigabyte board for my HTPC simply because I'd read the Abit has some double boot bug. Personal preference I guess, but I just wish I'd gone the other route on that decision with an extra 30 bucks in my pocket!
March 24, 2008 6:14:59 PM

Well, it's not going to melt on a moderate OC anyways so why worry? Tons of people have their Q6600 on 3GHz without any issues on that board.
March 25, 2008 3:03:01 AM

Hey guys,

Thanks for the help so far.
Currently my system is down until tomorrow after my Motherboard burst into flames :p  (long story). I'll be sure to post my VID value as soon as I can.

Also for the case, I have an Antec 900
The fans I have for it are:

1 - 200mm intake fan
3 - 120mm intake fans (two front, 1 window)
1 - 120mm exaust fan (back)
1 - Artic cooler
1 - PSU fan
1- GPU fan

Thanks again for the help!

I also have 1 more empty space to fit another intake fan.
March 25, 2008 12:30:25 PM

I believe the 200mm is exaust, but that is a great case. You shouldn't have any heat issues with an Antec 900. I wouldn't worry much about adding more fans for the overclock you seem to be planning. Besides if temps become an issue they are easy to add later.
March 25, 2008 3:33:46 PM

Hmm odd, I could have SWORN I posted my coretemp info. Now it's gone! Ahh well I'm running memtest on my compter right now, But If I remember right, my VID was 1.13v
However I'll have to confirm that in about two hours.

Thanks,
March 25, 2008 3:50:03 PM

Okay lets try this AGAIN.
Here is my coretemp info:

CPUID: 0x6FSB
APICID: 0
Revision: G0
Processor: Intel Core 2 Quad Q6600 (kentsfield)
Frequency: 1600.00MHz (266.67 x 6.0)
LGA 775
VID: 1.1375v

CPU#0: Temperature Readings:

tj. Max: 100 C
Core #0: 28 C
Core #1: 30 C
Core #2: 28 C
Core #3: 31 C

While watching the coretemp though, I noticed the VID jump to 1.23 sometimes. But mostly stable at 1.13. Is that normal?
I'll assume speed stepping is enabled somehow? Anyone know how to disable it? I have a Gigabyte p35 ds3l.
While testing on prime though (blend test0 it stays at 2.40ghz, with a VID of 1.184V

Thanks,
March 26, 2008 12:04:44 AM

I have read that guide :p  And then my motherboard exploded >.<
I'm just looking around to what other people did to overclock there's to around 3.0 ghz. Just something I can use as a template to start.

Again my VID is about 1.184V according to CPU-z
and 1.2375 according to Coretemp. (when running at full 2.40ghz and running a heavy prime95 test)

So if anyone can help me out, that would be great =)
March 26, 2008 12:29:47 AM

Set vcore to 1.300v. Set ram to 1.8v run it at 1:1 (aka system memory multiplier x2). Lax memory timings to 5-5-5-15. Set fsb to 333MHz. Set multiplier to x9. Leave NB, SB, FSB voltages on stock (auto).

This is, of course, after turning off speedstep.
March 26, 2008 2:10:09 AM

Uhh, Okay Mikey, go into the BIOS and disable speedstep, c1e, vanderpool disable bit, etc. All the processor options but internal cache. Then boot up with auto settings on the VCore and FSB and such, so its at 2.4 again

Then run core temp, so speed step cant step your processor down to a x 6 multi and that 1600 speed. Thats why your VID is so low. (And if its not why, you are a lucky MoFo!)

I'll give that a shot in a bit. Currently I'm running PRIME95 In-place large FFTs (max heat, power consumption, some RAM tested) and according to CPU-Z my cpu is running at 2400.1MHz with a x9.0. It shows my VID to be 1.184V

The vid is in core temp, your showing actual voltage(realtime).
Coretemp VID shows my B3 q6600 at 1.2625
In windows just at idle, cpu-z shows 1.232 (at 3.0ghz)
Open CoreTemp and tell us what the VID says on the bottom of the first collum of the program.
March 26, 2008 3:23:56 AM

Kewl, I just wanna make sure, because it was obviously showing us the speed steps effects, x6 and 1600.

Hopefully its a great VID, and just so you know, it may say that in Prime, but its small FTTs that you wanna run for heat and power, fire it up and see the difference. ;)  Trust me, blend is for ram, and small for CPU, large doesnt tell ya much of anything.

March 26, 2008 3:38:49 AM

This will also help me find out what makes core temp of that version fluctuate the VID. Mine never change, on 5 different mother boards, core temp always shows the same VID no matter the load status or what I have it OC'd to. Like now its at 1.496 volts for 3.8 But core temp still says 1.2625.

Only some people appear to have this problem.

--Lupi
March 26, 2008 3:41:33 AM

Okay here is coretemp values:

Frequency: 2400.00MHz (266.67 x 9.0)
VID: 1.2375
March 26, 2008 3:47:10 AM

Perfect! Thats a nice VID. You can hit prolly hit 3.8 or a lil more, since I get 3.8 with a VID of 1.2625. Good draw!

I have seen lots of 1.300 ones popping up all over. Next month I should have one or two new ones to play with. So have you decided on final OC goals yet??

Did you try small FTTs and watch you heat go up and CPUz's core voltage go a lil lower?

--Lupi
March 26, 2008 3:53:11 AM

I'm actually running the small one now, just to test. I'm not really sure what to OC to. I was hoping for 3.2ghz, but will probably push it to 3.0ghz, leave it there for a month or so, and then push it to 3.2ghz .
That's why I'm looking for help, just to be sure at what voltage I should be shooting for =)
March 26, 2008 4:25:21 AM

Well, that should be simple to attain. I'd guess you can reach 3.6 @ 1.4000 or so in the bios, so like 1.37 in windows. For 3.2, more like 1.300 in the bios, for 1.27 or so in windows.

That's just a worse case guess. Prolly a notch or two lower, and you temps will be cool at least to 3.6. I get 63c at 3.6

--Lupi
March 26, 2008 3:35:40 PM

Well I was thinking about doing it like this:

355 x 9.0 = 3.2ghz
cpu voltage control: 1.27125
Then keep increasing the voltage control until it boots, once it boots, notch it up once more..and start testing on prime
March 26, 2008 3:38:37 PM

That will be about 1.25 in windows, but you can try it. You'll prolly need more to be 8 hour stable with small FTTs.
March 26, 2008 3:59:51 PM

Well what would you reccomend the minimum to start at? I just don't want to put more voltage then needed, becuase that's un needed stress on the cpu.

Also am I right to assume this:

The amount of overclocking is determined by the FSB x the multiplier.

For example, my multiplier is x9, so whatever I set my FSB to, get's multiplied by 9, making the speed? The voltage is increased just to stabilize everything?

However reading an article about overclocking on my motherboard, it said this:

For an 800 MHz FSB this is set to 200 MHz.
For a 1066 MHz FSB this is set to 266 MHz.
For a 1333 MHz FSB this is set to 333 MHz.
You can also enter any other value like 300 (1300FSB).

Now by default mine is set to 200. My motherboard FSB says it has a 1333MHz FSB. So that means i can't go above 1333? or 33MHz in bios setting. Which means the max I can do is 333 x 9.0 = 2997MHz
Am I missing something here?
