Q6600s really do run hot!

hehe, my qx6700 cracks 82-84C on all cores under 8K FFT Prime load. good thing there are no applications that will ever make it burn up like that. 8K FFT in prime is just unreal. lol.

Q6600 @ 3.21GHz, 1.45 vcore

 

[Toadster]

mine will run in the upper 60's if I'm running BOINC 24x7 - plus my PC placement in the room isn't very good (stuffed under a desk in a corner)

 

[Yongsta]

Hmm so I should reserve a G0 stepping from tankguys?

 

[aigomorla]

dude....

*sigh* they wont believe you, because not a lot of people believed me when i stated this 3 months ago.

No one thinks im a cooling expert on this forum, except the few that pm me from time and to time.

But let me say one thing.


I TOLD YOU SO.


Anyhow...


if anyone wants advice on how to tame this beast, minus the G0 steppings which are suposed to run a bit cooler, pm me on water solutions.

Theres almost no way to overclock a Quad to 3.6 24/7 stable unless your on water.

If your looking for air solutions, i only recomend the tuniq tower, and ultra120 extreme lapped. You'll cry otherwise.

I can run at 3.4GHz on my Zalman, but it's buggy... I'm sure a bigger cooler would let me go higher - my room is just too damned hot to begin with

It's not that hot, it's merely CoreTemp using a Tjunction of 100C to calculate the temperature. There's still ~20C before the throttling, which is warm but not unusual or dangerous for OEM cooling.

 

[SerpentRoyal]

Quads have 100C throttling profile, so you should be able to safely push the CPU up to 85C. Most C2Ds are rated at 85C, which would translate to 70C as the upper safe limit for the chip. Again, I don't expect any chip to run at full TAT load 24/7.

My quad at near full TAT load. TAT doesnt work on Quads. :T

ambients around 75F <--- sorry typo ment F not C

My X3220, NAS, doing her WCG run for 24 hours. Thats about = to orthos on blend.


I run my quads to the MAX.


I dont have a screenie for my X3210. But she was getting same/near temps as my Q6600 @ same ambients @ lower clock.


Im telling you, water is the only way to go if you want good/high overclocks on these guys. BTW the X3220 does 3.7 on my new P35. 680i can rot in hell, and im very disapointed in it after getting my P35.

Only reason why i have the 680i is for SLI. Stupid NVIDIA.

 

[rich168]

which would be cooler

x3220

or the q6600?

THe X3220 has a lower starting voltage.

However on the 680i it hits a really nasty wall at 375fsb.


On the P35 this wall is nonexistant. So if i were to max out both systems, the X3220 would most likely run hotter at 3.7ghz vs the Q6600 @ 3.6

 

[Noema]

HP Media Centers with Quad Core? Whudda thunk?

And as Paris Hilton would have it, "That's hot!".

 

[n7]

The funny thing is how all the higher end PCs now are coming with 3 GB RAM lol.

Not 2 GB, or 4 GB.
3 GB, since HP doesn't seem to want to ship Vista x64 :laugh:

So they throw in 2x512 MB + 2x1024 MB since obviously Vista x86 won't fully show much over 3 GB...

Yeah, the HP heatsink & case airflow...err lack thereof...kinda made for some cozy temps.

HP Media Center with a quad-core?! Link plz.

@aigomorla: your screenshot here: http://i125.photobucket.com/al...73/aigomorla/Q6600.jpg

Is it accurate? 9x400 @ 1.175 V for your vcore? That's stable? If so, that's amazing. Mine runs 9x333 @ 1.232 V (in CPU-Z; it's 1.2625 V in the BIOS). Anything less gives p95 rounding errors.

1) what is your BIOS vcore to support a stable 9x400?
2) have you tried using CPU-Z version 1.40?

 

[lopri]

Mine runs 67~68C load (quad Prime LargeFFT) inside a case, @3.20GHz. It's not that bad. I use Thermalright HR-05 for NB, and keep the video card at the bottom PEG. An advantage for SLI boards.

 

[graysky]

@lopri: what is your vcore set at for 8x400?

 

[drakore]

Isn't there a voltage issue with CPU-Z. It reporting the wrong voltage after 1.5V or something?

Aigomorla, i thought we have this discussion already with BonzaiDuck. Air >= Water haha

 

[genec57]

How much hotter, in general is the Q6600 compared to the E6600?
Assume that all setting are the same in bios and that the cooling (water) is the same.
Is such a generalization even possible?

 

[graysky]

Good question, genec57. I dunno the answer. I think it's fair to say that he heat output will be double since there are 2 cores. Beyond that though, is anyone's guess. We can make an estimate that it's about double. Have a look at this chart running an X6800 @ 3.0 GHz. 32 °C load temp. It's roughly double on my Q6600 @ 3.0 GHz. Again, without the necessary controls, it's impossible to give an exact scaler factor.

Nobody is talking about overclocking a Quad to 3.6GHz 24/7 stable but you. You can get a great overclock of 3GHz out of a Quad on air. I don't understand why you assume a "good/high" overclock for a Quad is in the 3.4GHz+ range.

 

[lopri]

@graysky: I set 1.43125V in the BIOS, which gives me approx. 1.39V idle / 1.37V load in Windows. Also, AnandTech's Heatsink test should only be taken as an example, which showing relative performances among different heat sinks. Wesley himself confirmed that the 'load' temp isn't measured at 100% load, but around 80%. I believe he uses nTune to measure everything, also.

In that sense, his 'Overclocking Chart' is very misleading, IMO, because a system can be stable at 80% load evenly distributed to both cores, but unstable at 50% load if one core is pegged at 100%. Make no mistake, though. I'm not saying that quad-cores are not hot. It IS hot. Much hotter than I like it to be.

cpu-z has a problem when you raise voltage over 1.5v

please look at nmonitor for accurate voltages

@jpeyton

Im using those numbers because as i have mentioned previously, a 3.4ghz dualcore would seriously spank a 3.0ghz quadcore.

Then that brings us back to this question
1. Why did you get a quadcore? Was it for speed in applicaitons or was it because you thought it would be faster then a dual core?

2. Are you running the proper quadcore optimized programs?


As i have said, 3.6 and 3.7ghz quads are fairly rare. I would say about 10% of the people owning quads can keep it there stable. So everyone likes 3.6ghz as a number. 400fsb on 9x or 450fsb on 8x is a very pretty number.

So people who wants those numbers need to know the price it comes with it. If it doesnt apply to you, then ignore my posts. But if it does concern you, then you should learn from someone who has 2 running quads at those speeds.

If your happy with a 3.0ghz quad being spanked hardcore by a E6600 @ 3.6ghz, my previous E6600, then thats all on you. AS for me, a quadcore should outperform a dual core, even in non quadcore optimized programs. OTherwise, Why did i buy a quadcore to begin with?


Last note, a 3.2ghz quad vs a 3.2ghz dualcore, the quads have a slightly faster clock. But the heat difference between a 3.2ghz dualcore and a quadcore, is almost 2x


To make things simple, dont jump the july 22nd bandwagon for a quad. I dont recomend B3 steppings to anyone thats not prepared to cool these beasts down. The G0 steppings would be the best route to go, as they run a little bit cooler, and they overclock much better.

3.6ghz on a G0 stepping on air is most definitely possible, with a tuniq tower.
