QX6700 on Air

[dominick32]

Well, I decided to bump up the clock on my QX6700 today moderately and see what she can take on below stock vcore. I took off the Artic Cooling Freezer 7, and put the stock Intel Cooler back on. It actually holds load better up top vs. the Artic Cooler. The only trade off is the noise at 4000 rpms.


QX6700 @ 2.93 GHz **1.27 Vcore (1.26 load)**
P5B Deluxe
OCZ Titanium Alpha VX2 (2gigs)

Seeing that after 40 minutes of quad prime95, my temps are at 70*C in Core Temp and 46*C in asus probe, I dont think I am going to clock any higher than 3.00 GHz for the time being. I do have a Tuniq Tower 120 coming any day now, so maybe that will help me out some more. But so far both the Artic Freezer and the Stock Cooler both produce Core Temp and TAT readings of 70* to 73*C under load.. :mad:


I am happy however, that its proving to me that all 4 of my cores look to be strong, holding very high heat under low vcore clocked moderately over stock.
Here is the prime stable screenie at 2.93 GHz:

Can't wait to see what a Tuniq will do to this. I am hoping for the best for ya dom. Are you using your old P5B or did you get another one? I had thought you were going to get a different board and RAM for the Kents. Whatever ;). Hopefully yours will give me a feeling of what I can expect in about 3 or 4 months when I go kents :).

That hot. Are you on a really old stepping?
I'm using the stock cooler that came with my old P4, (cheap-o) a little Geil copper/silver paste and a sanded top and can run 3.46 24/7 and not hit those temps under load.
Maybe also check how much thermal paste you put on, it doesn't take much. Less than a small pea size drop.

You aint talking to a rookie bro! I have put more thermal paste on CPU's than a mothers changed her babys diapers. LOL :beer:

Notice what you said though: a sanded top. That means you lapped your processor. I will never sand or lap my QX. That is definitely attributing to the much lower temps you are achieving. I also researched XS for a few hours last night and my temps are right in line with normal on the stock cooler. As far as your sanded top, it probably helped you tremendously as there have been reports of uneven temperature distribution throughout the cores. Check out my screen shots. Core 0 and Core 1 are over 5 degrees warmer than the other 2 cores.

Thanks JT,
This is actually a brand new P5B- Deluxe (non wifi). And I am actually shipping out my current ram to Europe tonight. Getting in some last minute QX6700 benchies and I need some ram to turn the rig on. LOL

I am expecting a new 2X2GB Gskill 4 gig kit from Newegg anytime today also so I should have an interesting evening. The Tuniq should be here any day as well, so I will definitely keep you posted. :beer:

How is the flatness of the IHS on this quad when the last time you checked it ? Is it same or worst than your previous C2Ds ?

[Gautam]

I don't think the flatness of the IHS matters much when you're using the stock heatsink, since it only touches the center of the IHS anyways.

To me, dom's temps look sort of on the high side, and WH's overclock looks way above average.

I agree G.
As soon as UPS drops off this TT120, I will be sure to get some updated results for everyone. But early testing= Air Cooling is very tough with a quad core and these chips run hot.

Havent touched and quads myself, but this is pretty much the general consensus I have found reading up on their OC potential. Heat heat heat...

When you do get that Tuniq, it should help quite a bit. It is a monster. You can also look into replacing the 120mm fan for something with a considerably higher CFM rating like a Delta.

I would love to go quad, but I think I am gonna hold my E6600 until 45nm makes its debut. By then RC1 should be out for Vista as well, so it all falls together.

Good luck Dom, I'll keep an eye on this to track your progress. :beer:

Thanks bud. :beer:
I hope that Expedia situation works itself out for you. You dont deserve that crap.

yeah quads are sexy but i am so in love with my 6600.
look forward to seeing the TT 120 on this.

If I had that CPU I would not overclock, I would just overclock the bus to 1333MHz(or higher) and use the lowest voltage possible @ 2.66GHz. I'm waiting to get a Q6600, but these temps look crazy... I don't think 3GHz stock voltage will be possible with 60C load temps on my TT Typhoon...

[William Hung]

TAT Version 2.10 and the Intel Management Console that comes with the XBX board. I also have a case thermo couple that reads out on the front of my case, it's about 2-3 lower than what TAT and IMC give, but that's likely because the thermocouple is a little off the hottest spot on the IHS.

I've got two QS QX's, both are lapped and give very similar results. One is about 2-3 degrees higher under load.

Amibient case temp is 26C, since that also factors in.
I do have quite a bit of airflow in the case, but also have two HDD's and and pretty warm nVidia 7950GX2.

[Rattle]

sweet where can I get 2.10 I still have 2.05

These temps may look crazy for a C2D. But theyre definitely normal or a tad above normal for Quads. Go take a look at all the other air cooled QX6700's on Xtreme Systems. These guys are talking 75*C and 80*C load on stock voltage.:mad: 3.0GHz will be easy at stock voltage on these. Dont let the temps scare you. The only thing I am very hesitant to do until I get a TT120 is bump up voltage and try for 3.3+

Until I get proper cooling I will not touch voltage whatsoever.

The temps scare me because I want for one for 24/7 Folding... and it can get quite hot in the summer in NYC, especially in the room without AC (I don't live in the same place). I hate having to changed settings every few months to cope with the temperature... At 2.66GHz, What is the lowest voltage the chip will be 100% stable at?

I definitely hear you on that one. 24/7 Folding on a quad with my temps is very unerving to say the least. :mad:

In that case, even with stock clockspeed I would recommend at least water cooling for a 24/7 fold. At 2.66 GHz I was able to run 1.20 vcore perfectly stable as stated in my other thread. It idled in the 20's and loaded in the low 60's.

[jtjuska]

I don't blame you at all for not wanting to touch voltage on a $1000 proc. I am thinking about that as well and just trying to figure out how well my apogee will deal with the heat output. Hopefully the TT120 will drop your temps though and we can see some Kents goodness.

[William Hung]

I'm 24/7 folding on mine, and while I had some issues with 64-bit ubuntu Linux on Vm-ware, I'm 100% stable on Kubuntu and VM-ware at 3.46 air now.

TAT 2.10 was on a link on XS a while back. I don't see it posted now. I'm sure they are all pretty much the same. They read the temp directly from the proc.
