Q6600 GO temperature question

[lunnytoon]

I have a Q6600 GO overclocked to 3.2ghz, and my temps at idle according to coretemp are ~40 degree mark and ~52 under load, so i was just wondering if they are safe temps.

My setup
Q6600 GO stepping @355*9=3.2ghz
VID is 1.275 and that is also what i am using for the overclock as it seems stable under Prime and IBT
OCZ Vanquisher cpu cooler
Asus P5Q (just the vanilla board)
4 gig OCZ ReaperHPC PC8500 running @711mhz
Asus 8800GTX
Enermax Galaxy 850 watt Power supply

I have 1 120mm intake on the front of my case, 1 90mm fan on the side blowing inwards and a 120mm exhaust fan.

Realtemp gives me temps of ~5 degrees lower than coretemp and everest ultimate so i am unsure what to believe.

Any suggestions would be appreciated

temps are fine. Good voltages.

You don't need that ram though unless you're using tight timings or low volts. Might want to try doing one of those or run it at 444mhz.

Apologies, my ram is running at 355 on a 1:1 divider.

I just got confused as it's 711mhz as reported through the bios.

When i said my load temps i was meaning gaming etc, if i run prime it can hit ~60 and ~68 using IBT which is why i am concerned, i am aware that they put much more stresses on the cpu than games and they never hit that sort of temp in any other scenario other than stress testing, but i would like to bring them down a bit if i could.

Thanks for the reply

I was considering using 400*8 for the overclock. Would that help in any way?

 

[F1N3ST]

400x8 Is better if you only want 3.2ghz, it makes your RAM and FSB run at good speeds.

 

[lunnytoon]

I am happy not to push any higher than 3.2 while using air cooling and im not to keen on going down the water cooling road just yet at least. I was wondering if a different cooler might help though, or should i be happy with what i have setup at present?

 

[Gillbot]

idle temps are meaningless, it's the load temps you want to watch. As long as you keep them under 70C, you are fine.

 

[lunnytoon]

Well its only really the IntelBurn Test that has any hope of getting near that sort of temp so i guess i am happy.

I have just changed my multi from 355x9 to 400x8, gonna see how i get on with this.

Thanks for the info though

 

[LOUISSSSS]

you dont need to use intel burn test. its pretty useless.

use OCCT, 2 hours of it passed and your cpu will be stable enough for you.

 

[lunnytoon]

Thanks LOUISSS will give it a go. Is that also better than runing multiple hours of prime95?

 

[LOUISSSSS]

i trust OCCT w/ 2hours.

or u can waste 24 hours running p95 w/ the same result. in the end both will be stable for everyday usage

 

[lunnytoon]

Well it's 30 minutes into the test now, i shall update when and if (hopefully) it finishes sucessfully.
Coretemp currently reads 63,63,61,59 so fairly acceptable

BTW it's set to do 2 hour mix, hope this is correct cos i aint used this before?

 

[lunnytoon]

2 hours OCCT and it's stable 400x8, my memory is at stock timings 5,5,5,15 is it worth trying to tighten them up a bit?
How do you post screenshots on these forums?

My G0 is 9x367=3.3Ghz w/VID of 1.2625V and idle temps are 22C (ambient is 18C).

(my G0 is lapped, with a lapped Tuniq120)

40C idle seems high to me but your load temps of only 52C are not of any concern.

One thing to realize is the TJmax for G0 Q6600 is 90C but most programs assume TJmax is either 100C (coretemp) or 95C (realtemp).

See slide 15 of this official Intel document regarding DTS and TJmax for G0's.

For correct(er) temps you need to use coretemp and set the TJmax offset (under menu settings) to -10 such that the TJmax it reports on the frontscreen is 90C.

Performance-wise, whether you go 9x355 or 8x400 to get 3.2GHz you aren't going to find any difference in real-world apps or benches.

You will wear out your NB faster though running it at 400MHz than 355MHz (pm Aigo, he's got mountain of data), but if your mobo replacement rate is high anyways then go for whatever makes you feel good about your rig as you'll likely replace things before they die in that case.

Bingo. As in, I'm afraid that I'm being too cautious with my Q6600 G0, and I won't be presented with an "opportunity" to upgrade it. Can I count on it dying reasonably soon if I push it to 75C?

 

[lunnytoon]

I have been reading quite a bit trying to find out the correct TJmax of the Q6600 GO stepping and have always seemed to come to the conclusion that it was 100.
If what you say Idontcare is correct, that it it 90 then that makes my load temps ~42 degrees which i will be very happy with.

With regards to my motherboard, i was under the impression that my P45 chipset P5Q was quite capable of 1600 fsb out of the box, which is what i have it set to now, so did not think i was overclocking the motherboard at all. Also my ram timings are set at 5,5,5,15 so that aint been overclocked either, but please correct me if i am overlooking something.

Thanks again

I'd just like to point out for the record I am merely the messenger, it is Intel that says TJmax for G0 is 90C...its not IDC saying its 90C, its IDC saying I believe Intel when Intel tells me its 90C (which is what they did).

laugh: I feel like I just did a Bob Dole presidential candidate commercial...speaking in the third person as he was so famously noted for doing..."This is Bob Dole here folks saying please vote for Bob Dole, Bob Dole appreciates your support, that's a swell guy there that Bob Dole..." )

 

[lunnytoon]

Im not saying i don't believe you, in fact after reading the pdf you linked to i have adjusted my offset in coretemp also. Like you say it's Intels own words.

Also says that they revised the TJmax in november of that year raising it, which suggests that they must have originally had it at 80 or 85.

Thanks for the link btw and thats a good VID you got on your Q6600 must have got lucky with that.

Yep, actually they really botched the original distribution of the TJmax information for 65nm quads and for months (even after the presentation was revised) it was a horrific mess of misinformation across all the forums in all the threads.

I'm just happy it finally all got sorted out to be honest, I figured it was 95C just going by my ambients but to find out it is actually 90C (and thus my chips were 5C cooler) makes me all the happier.

For business related reasons I actually ended up with five G0 rigs, the VID's ranged from 1.2625 up to 1.2750, a nice tight range and nice and low as you say. It made for some easy overclocking, all the rigs run 3.3GHz on stock VID settings (albeit with lapped tuniqs).

These newer G0's though, very typical to get high VID's above 1.3V and very typical to struggle above 3.2GHz. It was fun while it lasted though. :beer:

 

[lunnytoon]

I think my next move, might be to look at a better cooler, although i aint keen on the idea of lapping because i personally would probably make a mess of it. Also i don't see the need now, my 4 cores are currently reading 30,30,29,28 with the altered offset in CoreTemp so i am a happy man.

How much did lapping shave off your temps just out of interest?

 

[California Roll]

Hmm, this means my idle temps are 28C. Interesting...

Yep, if your CPU is set to use all the power-saving stuff it will idle literally a few degrees above your room's ambient temperature. (depending on what else you got shoved in your computer case, and whether you have good airflow there as well)

I've confirmed this with temp probe on the heatsink. It stands to reason, there is a reason Intel's retail HSF for the Q6600 was so paltry, it didn't need to be very beefy to still maintain decent temps at idle and load on stock cpu settings.
