Quad Core Thread: Overclocking, Cooling, Motherboards, Troubleshooting & General Info

Lets have a look at the temps after a few hours of orthos hehe.

LOL, they are still climbing slowly after about 27 iterations of Prime 95 (one per core). I'll leave things as they are and see where they settle. They are still significantly better than they were before I lapped the CPU!

OK, I just played with my nuts some more (fnar) and things are looking good at around the low 50's/high 40's mark.

Cheers,
Stephen

Was the IHS very uneven when you lapped it?

I lapped my Thermalright 120-Ultra base, and that was very convex.

BTW, just gotta ask... what's with the pink handbag brigade

I took some pictures while I was polishing it, haven't uploaded them yet. Basically, the edges were where the copper showed first, followed by a point in the very centre, then things spread out from there until the whole of the IHS was copper coloured. So yes, the IHS was concave.

I started of using 280 grit sandpaper, moved up to 600, then 800, then 1000. Don't think I made it onto the 1200 I bought, since I wasn't aiming for a mirror finish.

Didn't you know, it's pink hand bag day today!

See Zak's sig.

Thanks! Sounds like lapping certainly evened it out quite a bit. I agree on the mirror finish - not needed - so long as it's relatively flat, thermal paste will do the rest.

I think Clunk has the edge on you with his fluffy little number

OK, so she's been cooking for a little while and things aren't quite as good as I had hoped, but still significantly better than they were.

Load temps are:

Core 0: 57°C
Core 1: 56°C
Core 2: 55°C
Core 3: 55°C

So cores 0&1 are about 9-10 degrees better than they were, cores 2&3 are about 4 degrees better. The Arctic Ceramique still has to cure though, which might drop another couple of degrees. The other thing I could do, but don't really want to because of the nuisance and hassle factor, is to lap my waterblock too, which means more or less draining my loop.

Might be good for another degree or so though...

Cheers,

Right after my day of adventures Ive got a suicide shot of 3.8ghz from this morning, and a new 24/7 clock 3.4ghz @ 1.45v-core and 1.50v on the northbridge.

After a couple of hours on orthos it was 60c on every core and the pwm's were between 80c~85c,
Overclocked the memory aswell to 1134mhz.

so Im very happy just letting it cool down now before a mamoth attack of BF2142 later tonight.

I'd leave it alone at that - looks like a good result

[daza]

Hehe, nearly there 7hrs stable at 3.4ghz with 1.46 v-vcore and 1.48v on the north bridge.

Just got to do the memory test tonight, and then try and crack 3.6ghz on Wednesday on my day off, and the 3.8ghz shot, crashes just as I started prime95 oops

[daza]

Yep good ol double post sorry guys.

Anyway 24hrs stable with the memory at 1134mhz (2:3 divider), and cpu at 3.4ghz.

Shall be going for 3.6 tomorrow.

Thats what my 24/7 ended up as

Hi all !

First, a big thanks to you for this topic, I learned a lot by reading it.


I've got a temp problem on load with my Q6600 (B3), not yet OC (and if I can't resolve the prob, it will never be OC). I put it on an Asus P5k Deluxe, with a Noctua UH12, all of that in an Antec Nine Hundred (the temp of air going out of the case is like the ambiant temp, very good case (but noisy lol !) ).

So on idle, the 4 cores are around 41-44° (I don't have the precise values), that seems normal to me. But on load, the cores temp grows up to 67-71° !!

First I wonder if there is a relation between idle temps and load temps, as on idle, the temps seem similar to a lot of yours.

Then, I think that it could come from the application of thermal paste I made. I carefully put it on all the correct surface, but then I read on on this thread the method of the "line" application. Have someone photos or links to photos, to see wich quantity is necessary and how the paste must be put in line ? I'm a bit afraid to make a wrong application...


Precision : my OS is XP64, I wasn't able to launch 4 SuperPi at the same time. So I checked the temps (with Coretemp) during a 3dsmax + mental ray rendering (mental ray is a 3d renderer able to generate enough threads to use 100% of the 4 cores)


I hope you can help me a bit to get cooler temps, this pc will used fo 3d rendering, and I would like a lot to speed up my rendering time by overclocking the cpu.

But this thread already learned me a lot, and i thank you again. and sorry for my english...

is what you are looking for. I am just in the process (this morning) of putting my Q6600 rig together so I hope that the temp issues are resolvable.

Those temps are high for stock settings. I would reapply the thermal paste first and see if that helps.

[Shimrod]

Yeah thank you, but I already read this well-done pdf...

I wonder about the quantity to put, and how to make it in line... I guess it must be equally put, to be equally spread... (the real problem : half seed of rice --> line of rice ! )


However, I'll try as soon as possible, and tell you if it's better. Thanks again.

Info for Clunk

Mostly From Scan:

Q6600 G0 (vid 1.2875)
Gigabyte P35-DS4 motherboard (rev 1.1) - recommended!
Etasis 750W PSU
Crucial Ballistic 2x1GB DDR2-800
256MB 7600GS
Samsung 320GB SATA II
Thermalright Ultra-120 extreme with Scythe 120mm 1600rpm fan

Motherboard BIOS (F4) supports G0 out of the box and boots up fine with memory at default 1.8v (detected SPD using slower timings).

Running 8x400=3.2GHz, 1.35vcore set in the bios, open build on the bench.

Some vdroop, reading 1.296 under load (1.31 idle) in cpuz.

Temps are EXCELLENT, 39-44C under load at 20C room temp

I've not really played with it yet, just went straight in at that speed and have been running SETI ever since. She's rock solid stable so far and I'd recommend all of the above.

[Clunk]

Thanks Phil, I'll add the cooler and the board now

Anyone else want to add a recommendation?
