I'm curious as to what people have their q6600's at. A lot of people stop at 3Ghz but I want to know about those who've gone further, on air ONLY, and what your voltages are? Just copy/paste the setup below and put your specs in accordingly. For Speed, PLEASE put the total Ghz with fsb x multiplier: 3.2Ghz - 400x8, 3.2Ghz - 356x9, etc...

 

Motherboard: Asus P5B-Deluxe

Speed: 3.2Ghz (8x400)

CPU vcore: 1.3375v
FSB vcore: 1.3v
NB vcore: 1.45v
SB vcore: 1.057v

 

Prime 95: 24hrs

 

Temps:
Idle: 38,36,35,35
Load: 58,56,55,54

 

Thanks!

OK... I'll bite:

Motherboard: DFI LP P35 T2R, with the extra heat pipe installed on the CPU/NB and out the back of the case.

Speed: 3.2Ghz: (8x400)

CPU vcore: 1.28 (1.25 was default)
FSB vcore: Auto
NB vcore: Auto
SB vcore: Auto

idle/load temps: Around 32c at idle, P95 test 2 stabilizes at around 57c and sits there as long as I care to run the test. Like I mentioned earlier, I have the extra heat pipe that comes with this mobo set up to help with the CPU/Northbridge. The CPU cooler is a pretty pedestrian Zalman 9500, which is aimed at the exhaust fan and assisted by a side fan blowing cool air on the RAM and CPU Cooler intake area. The Northbridge runs a little warm (in the mid 40's), but has never exceeded 50. So I left the stock heat sinks alone. They're bolted on tho, so I may take them off and replace whatever grease is in there (if any) with the good stuff...

This was actually a stupidly easy overclock. The only thing that gave me any trouble at all was that this combination doesn't like running the 4 1GB DIMMS of DDR2 1066 I have at the rated 1066. 2 DIMMS at 1066/5/5/5/15 (and a bit higher) were fine. But with four?? I can set the dividers up and run all 4 at 1000Mhz at 2.2 volts with good stability. But it doesnt' like going any further than that without pushing stupidly hard. Since I intend on using this comp until Neph becomes available I just set the memory at 800 (1:1), tightened the timings a bit, dropped memory voltage to 1.9 for insurance, and declared victory. At those settings, the DIMMS remain just barely warm to the touch.


Quite frankly, for a while I was concerned about not enough voltage here, there, and in the other spot. Or if my timings were off, or *something* wrong. So I would sit and think about what I should change. But then pragmatism sets in and I leave it alone. Don't break what isn't, yah??

It'll run P95 test 2 overnight...

And yes - Voltages were what I alluded to when I said I kept thinking I should change X, Y, and/or Z. I probably just got a lucky combination of board and proc, is all. Decided it'd be best to not complain. :D

just put the +0.1's in the voltage places in your post. On gigabyte boards, no real way to see them. I think the MCH is NB. Anyone?

Wouldn't running at 9x400FSB be a little better heat/voltage wise on all the components? I'm just a nub so correct me.

Which is better: 3400@ 425x8 or 378x9?
Which setting will use the least voltage and would be most stable in the long run?

from what ive read 378x9 is better, lower FSB requiring less voltage

Yes, running 9x400 would be a better idea. Performance wise, there is no difference, only in memory benchmarks.

Well, I decided to keep the 425x8 because it provides me with the best frequency for my ram, 1064 @ 4-4-4-12. I was prime stable at 1.375v so now I'm lowing the voltage to 1.362 to see if its still stable. For those using Ballistix Tracers PC8500, running around 1064 @ 4-4-4-12 will require you to up the voltage to 2.3v; at 2.2 its not prime stable. I just bought an OCZ ram cooler which helps with the heat, recommended for anyone running ram >2.2v because they do get hot.

I will report back to see if 1.362v is prime stable for 8hrs.

By the way, going from 1.375 to 1.362v reduces my idle and load by an average of 4-5C.

Alrite, I'm prime stable for 8hrs at 1.362v running at 3.4Ghz. I think i'll keep this overclock until I get my Zalman Reserator 1 v2 next week. Hopefully with that I can overclock to 4.0Ghz and also my 8800gtx to 640/1100.

4GHz is too hard to do on air. Even the best air-cooling, the Thermalright Ultra 120 Extreme can't do it.

The Zalman Reserator 1 v2 is an external water cooling unit. I getting one for free next week along with a 8800GTX water block. I don't know if I should hook up the GPU water block as well because I'm pretty sure it will void my lifetime warranty.

So if I am able to clock it at 3.8-4GHz watercooled, with maybe 1.4v, would it be safe to run it 24/7?

I'm not sure about that water-cooling, but the best air-cooling beats most WC that costs under $300.

The lowest voltage I have seen for 3.6Ghz used for 24/7 is 1.4v. If you want to hit 3.8GHz, you'll probably have to do 1.45V or higher.

I'm running 3.6 GHz, vCore is set to 1.45v (which reads as 1.444v in BIOS). 39*C idle, which reads as 1.440 in CPU-Z. 67*C full load, which reads 1.392 CPU-Z. I'm using a Zalman 9700 NT with Arctic Silver 5. I may or may not be able to go lower on the Vcore, but at this point it runs rock stable in Prime95 (both blend and small FFTs), so I really don't want to mess with it. It took 3 days to get it dialed in.

Some of these OCs seem totally bogus to me. To go above 3.4 GHz, you need to be running at 1.3v minimum (BIOS setting). If you're running at 3.6 GHz on air, your temps are going to be in the 60s, period, regardless of what solution you have (unless you have the stock heat sink, in which case you'll melt).

agreed....I had lots of luck with stability. Successful boots @ 3.0, 3.2, 3.3, 3.4, 3.533, 3.6.....all no problems
Different RAM and FSB clock...linked mem...unlinked mem...only a few combinations didn't work out. All below @ or below 1.425v

But the temps were never standable over 3.3ghz....Next time I do a big overhaul I'll lap everything and try to control the heat.

Don't lap anything...waste of time. Just get a high quality heat sink and a high flow case (for example, I'm using the aforementioned Zalman in an Antec 900 with the two optional fans...450+ CFM).

I'm not even going to touch the ignorance in the last 3 posts..

But let me just say, there is a thing called VID. The lower the better. BIOS setting <> Windows Setting. BIOS has jack crap to do with real voltage (it's the VID setting, vOffset comes into play). I know someone who does 3.6 GHz at 1.288 load vCore.

http://i39.photobucket.com/albums/e189/cnumartyr/p353600mhz30minutes.jpg

Check that out, under 60C with air cooling.

Also, lapping can help a ton. At the same time it might do nothing. It all depends on the skill of the person and the relative fit of the heatsink and IHS.

Yep.. I wish I had a better VID, but I can't complain too much.

I must admit 1.2000 is the lowest I've seen. You won the lottery!

Yes Guys I am really pleased with this processor I had another with a VID of 1.225v and could do 3.6GHz on 1.30v and 3.8GHz on 1.41v, but this is in a class of its own. Actually there a quite a few Batch# with a VID of 1.2000v.

I think I can squeeze a little more out of it, it is currently 4.5h into Prime on 1.184v at 3.4GHz and that will probably be the specs to run during summer. I will post a screen shot on completion.

After the stock voltage test I will do a 3.8GHz run and post a screen shot for all to see. For those who are looking for a Q6600, look for one that has a low VID, though this does not guarantee a good Over Clocker, what it does it allows you to do is to start from low voltages and reach a higher speed with lower voltages.
Sure there are some Q6600 which have a VID of 1.325v that can do 3.6GHz, but many fail because folks do not have adequate cooling and therefore back off.

But let me just say, there is a thing called VID. The lower the better. BIOS setting <> Windows Setting. BIOS has jack crap to do with real voltage (it's the VID setting, vOffset comes into play). I know someone who does 3.6 GHz at 1.288 load vCore.

Check that out, under 60C with air cooling.

Also, lapping can help a ton. At the same time it might do nothing. It all depends on the skill of the person and the relative fit of the heatsink and IHS.



OK, cnum, I'll accept that. But I'd like to ask a few questions. How long have you run Prime95 at that setting? Also, I'm far more concerned with what CPU-Z is reporting at idle, not at load.

First - My chip isn't anything near impressive. Check out Wireless's and Obe's. Second - 10 Minutes is the general consensus as far as the point of saturation for a chip (the heat buildup).

1.416 Idle, 1.400 Load. That's a 10 hour Small FFT test.

Hello everyone. I'm another one of these people that is new to the whole overclocking scene but am trying to get the most out of my setup as possible. So far I've been able overclock my Q6600 to 3.0Ghz without a problem. What I'm wondering is, what more can I get out of it because this overclock has hardly added anything to the temps of my CPU and motherboard (apart from maybe 2 degrees).

Anyway, I have an ASUS P5N-e with Q6600 and a Thermaltake heatsink and fan.
Using different poeplese guides around forums, I've change the following details to overclock the Q6600 to 3.0Ghz:

FSB Memory Clock Mode : Unlinked
FSB (QDR) Mhz : 1333
MEM (DDR) Mhz : 667
Vcore Voltage : 1.325
Memory Voltage : 2.085
NB COre Voltage : 1.393
VCore offset Voltage : Auto
LDT Frequency : 3x
And Memory Timings set to 5, 5, 5, 18, 2x

I was amazed with the performance increase I got and as the temps haven't really changed that much I sure I can get it up to 3.2Ghz or maybe even 3.4Ghz running stabily. My cpu is the G0 model by the way and I'm running bios 0608.

Can anyone pass in some advice as to what I could change to achieve those speeds?

Thanks so much for all of your help.

Just keep going until you can't go any higher on the voltage (ie: less than 1.5v idle CPU-Z), or the temps max out (ie: 75*C full load, hottest core, cooltemp) You'd probably want those maxes to be about 1.45v and 71*C to be safe. I'm at 1.392v full load @ 67.5*C, 3.6GHz

Thanks JJBlanche. What do you use to monitor the CPU temps?
I'm currently using ASUS Probe II and even on full load my CPU doesn't get much higher than mid 50's at 3.0GHz but I'm not sure how reliable it is.

Asus Probe is measuring Tcase, which is about 10-15C cooler than the hottest Core. Your cores could be anywhere from 55-65C. Download Speedfan (link in the sticky at the top of the forum).

Thanks cnumartyr. Btw, how have you managed to clock your Q6600 at 3.89 and keep it stable :). I'd just be happy with 3.2 or 3.4 but that is impressive.

It's benchmark stable. The highest I can get 24/7 Prime95 stable is 3.75 GHz. I peak at about 70C on the cores at that point. I run it 24/7 at 3.6 GHz so I can turn the fans down a bit and have a quieter PC.

Any chance I could pester you for your setup cos that sounds mighty impressive.

My P5N-E won't give me as much options to amend as later boards but you can see the typical options I have from a few posts earlier.

Reply to diddler1979

Even if I gave you the exact setup it's not going to work the same on your board with your chip.

Just go in steps, you know how to OC. My only advice is that when going above 333 MHz Bus to get the CPU stable at 3.0 GHz. Then when you go to 360 or so MHz, use an 8x multiplier so you know the CPU is stable and get the board stable. Then move to 9x once the board is stable and then get the CPU stable. Repeat over and over.

No worries cnumartyr. I wish I new more about OCing that you give me credit for :).

I'm going to try and set the FSB up to 1468MHz and DDR2 up to 734MHz for a bus speed of 367MHz and 3.3GHz clock but all of this will be with the Multiplier set to 9.

How does adjusting the Multiplier to 8 change those settings?

I'm sorry to pester you guys but the whole OCing scene has got me really interested at the moment.

Here's my thing on it, and no this has nothing to do with your specific situation. Just in general.

When OCing you are changing 3 things, the board (NB), the CPU, and the RAM. If you OC all at the same time you may not know what is causing an instability. If the RAM is rated at DDR2-800 and you have it stable there, that eliminates the first "problem." Now that the RAM is out you have the NB and CPU left. If you know the CPU is stable at 3.0 GHz and the board is stable at 333 MHz (333x9 = 3.0 GHz) then you can go to 375x8 (3.0 GHz). You know the CPU is stable, so any instability is likely the cause of the board. The RAM is in 1:1 so is running below spec (750 MHz) and the CPU is running where it has been stable.

You use smaller increments obviously, but this helps eliminate some of the guesswork. If you KNOW it's the NB, or RAM, or CPU it becomes much easier to fix. As an example, I know that 3.6 GHz (400x9) is solid on my board. So when I go for 450 MHz Bus I back the CPU down to 8x and leave the voltage the same. Since I've had the RAM stable at DDR2-1066 running it at DDR2-900 is no problem. That let me get the board stable at 450 MHz and then go back and work on the CPU stability up to 3.89 GHz (433 MHz Bus).

Edit: Short answer: Changing the multiplier will drop the CPU speed letting you know if the board is stable.

As a side note, the most IMPORTANT thing you can have as an overclocker... is patience.
