Core 2 QX6700 SSSE3 crunching time
CAPTAIN FUTURE:
--- Quote from: msattler on 01 Mar 2007, 10:29:29 am ---Asus Probes reads 56-57c, Coretemp reads 80-82c. I believe the difference (anybody correct me if I am wrong) is that Probe's reading comes from a thermal diode in the cpu package the same as the bois hardware monitor does, and Coretemp is reading the DTS information directly from the cpu. My understanding is that tthe DTS information is actuallly a more accurate reading of the actual cpu die temperature.
As far as the AS5 goes, I have lapped both my cpu and the bottom of the TTBT cooler that I use (I did not see much difference between lapped and non-lapped temps, but was making other changes at the same time, so did not have a direct A-B comparison). I usuallly apply the AS5 to the surface of the cpu and then spread it out by using the edge of a credit card (a razor blade works well also) back and forth until I have a very thin, smooth coating of AS5 across the entire face of the cpu I then mount the heatsink and remove it to check if I have the paste transferred evenly from the cpu to the heatsink, ensuring that the mounting is even and I have enough paste to join both surfaces. You want to use as little paste as possible while still assuring full contact between the cpu and heatsink. When this looks right, I than use the credit card again to carefully smooth the compound out on both the cpu and heatsink, and do the final mount.

Hello!
In the manuel of the compound they say:
Page 2, # 3, Break-In Period...
http://www.arcticsilver.com/pdf/appinstruct/as5/ins_as5_intel_dual_wcap.pdf
So I must use the PC... maybe 16 hours and then over night 8 hours switch off. This procedure for around 8 days?
How you had done it?
You saw maybe after the first days that the temp fall a few more °C?
Friendly greetings!

As CPU cooler I'm using Thermalright Ultra 120 with Noctua 1200rpm fan. I have in PC Probe II about 43°C in full load and Core Temp tells me that cores have about 60-67°C thats ok I thing (Tjunction is 100°C).
With case you are right I must do something with airflow. Now I have 1200rpm intake and 800rpm outtake fan. And it's not enought I think.
Fast,faster,the fastest crunching... (by Intel) ;D
P.S. How fast you are going with QX6700? And with how high Vcore? I tried 3.2GHz @ 1.4V (QX6700 B3 revision ES)
Thanks

Right now I am running at 3408mhz, 426 x 8, ram is at 532.5mhz/1065ddr speed, 5-5-5-10 timings. Asus Probe shows 57c at full load, vcore is 1.42v in Probe, bios is actually set to 1.525. Mobo is an Asus Commando.

Nice! ;D :o
I'm running at stock speed on the same board and the highest speed which I reached was 3500MHz 350x10, ram was at 450/900 ddr speed, 4-4-4-12 timings vcore 1.45 was set in BIOS. It has problems after few hours of ORHTOS Prime test.
I will try add some volts ;)
But I have worries about cooling I'm using Thermalright Ultra 120 with 1200rpm Noctua fan.
Your CPU must produce much more than 130W on stock ;D. What cooler do you use?
I love this machine, it's performance is incredible.

Thank You for the compliment.
As for the power dissipation..............
Much more than 130w. I have done some calculations for the dude that is working on a custom phase change cooler for me, and I think that the quad OC'd to the range of 3800mhz on 1.55 vcore or so was generating some 250-280 watts of heat. It's no wonder that my fiirst attempt at phase cooling faiiled. the Vapo LS simply cannot handle it.
Anyway........I use the Thermaltake Big Typhoon for air cooling. It has gotten me very good results. Other OC'ers have their favorties, of course. I upgrade the fan to a Silverstone FM121 or FM122, gives another 1-2 degrees of cooling (not much, so TT must have the stock configuration dialed in pretty good.

I deployed the SSE3 optimised client on my Qx6700 yesterday and it makes a big difference to my setup. I am crunching a large workunit (62 credits) in 4000 secs and because there 4 going at once this sure is a good way to munch those units.
My moderatley overclocked Quad core specs is as follows :-
Qx6700 on Asus P5D Deluxe FSB (290x11) 3190Mhz
Corsair XMS2 PC6200C4 at 5-5-5-18 at 966Mhz
BTW I have deployed 4 of the optimised code versions across 5 active machines and they have all experienced a large step in performance. :o
Sir Nutsalot of KWSN. ;D

I have a small question for Jezak
What voltage are you using with your memory to acheive the high 1065 speed that you are getting at the relaxed latencys you are using. I have the same memory and the commando motherboard and the P5b deluxe are quite similar although I understand the commando allows greater flexibility to increase the voltages much higher when pushing things further

I think you may be confusing some posts.....
If I sorted through the thread correctly, Jezak last reported 900mhz at 4-4-4-12 timings, I had reported 1065mhz at 5-5-5-10 timings. I am running Corsair Dominatior PC9136 at 2.2v on a Commando.
Of course, pardon me if I am wrong.
