Core 2 QX6700 SSSE3 crunching time
jezek:
Thanks to all for their ideas. I didn't do any OC because I have cooling problems @ highter speeds.I'm running stock speed @ about 50°C (all cores) in full SETI. I think that the main problem is memory brandwidth.I have new Corsairs on the way and now runnig 667MHz CL5 in single channel that is the main problem. I forgot it... Ones more thanks for your time :)
Fast,faster,fastest crunching.

You should see a definate improvement by getting your RAM in dual channel mode.
And I would highly suggest looking into a better cpu cooling solution. If you are running at 50c at stock speed, either your case temps are a bit high, or your cpu cooler is just not quite up to the task. I have had great results with the Thermaltake Big Typhoon and Arctic Silver AS5, but if you check out the various OC'ing forums, other folks have their favorites as well.
Good luck and good crunching!

Thank you, I have now 2x1GB Corsair XMS2 800MHz CL4 in dual channel and it's crung very well ;D
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
CAPTAIN FUTURE:
I have an Intel D975XBX2 with the QX6700.
Intel Desktop Utilities tell me 22°C to go to max. (BOXed Fan on 2.000RPM) (room 22°C)
CoreTemp tell me 71 - 79 °C
I let run my QX6700 2,5 months with this temp... when the temps right... I would have burned my QX6700...
because:
I called Intel today: max. temp. 65°C ! :o
http://processorfinder.intel.com/details.aspx?sSpec=SL9UL#
Yesterday: BOXed Fan on max. ~ 2.780 RPM and IDU shop me 30°C to the max.
CoreTemp tell me 61 - 69 °C
So I ~n't think that CoreTemp show you/us/me the right temps from the QX6700...
I had probs now with the Rev.2.2B...
Boinc frozen...
Now I have my PC off... :'(
ordered Arctic Silver 5, Thermalright SI-128...
Soon he will run again... with better temps... I hope!

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.
