    You don't really want to be over 65c on both cores while CPU is at 100%.
    its nearly 3 hours on prime5 blend torture passing OK, cpu all 4 cores 100%, 2.64GB Ram used, so far temps from realtemp:
    core0:61*C
    core1:60*C
    core2:58*C
    core3:59*C

    will leave my pc on overnight.. holpefully is doing ok till now ?

    Judging by those temps you should make 3GHz on comfortable temperatures. Let Prime run for another 9 hours first so that you're sure you're stable. Also keep an eye out for the reboot loop.

    I understand that you should Select Advanced and Click Round Off Checking if you are planning on letting Prime run unattended. Something about this makes sure that it shuts down a Core if that Core fails... I think I read about it here.

    Stress Testing and Minimizing Your Vcores

    The goal of stress testing is two fold:
    1) To arrive at a stress test stable system (>24 hours with no prime95 errors).
    2) To minimize your vcores and thus minimize heat product both on your CPU but also on your NB/SB and other MB components.

    Prime95 will run and every now and then it will check the values it’s calculating using your processor to its internal standards since its torture testing using known values. Assuming you enable error checking, you’ll be notified if your values differ indicating an instability. This is why it is IMPERATIVE that you enable error checking within Prime95; again, if you don’t enable it, you WILL NOT be notified of errors!

    Do so simply by going to the “Advanced” menu and enabling “Round off Checking.” If the system isn’t stable, it will report an error and stop stressing the core that gave the error.
    I do.

    Thanks for that, just selected that option ;)

    @psycho101

    Thanks for your support, temperatures are staying more or less the same, eventhough lavasys everest reports different temps? im using latest version 5.02.1750, please check screen shots..prime 95 still doing fine..

    Realtemp by default is set up for 45nm dual core chips. Hit settings and change "TjMax from 100 to 90 and the temperatures should report correctly.

    120 more minutes and it completes 12hrs.
    everything seems ok, prime 95 still running with no errors..
    changed TjMax settings from 100 to 90 as Psycho101 suggested.

    I have left it for more than 12 hrs, core temps @52*C max..prime 95 without errors.rebooting loop dissapeared..board more than stable..

    Waiting for your suggestions/instructions to start overclocking according to my details/results..




    Thanks,
    Kannanni

    This is a big jump in FSB and an 800MHz core speed bump, but it should be pretty stable as long as you have a good chip. Monitor temps carefully, and do a hour or so of Large FFTs in Prime, before moving on to an over night run of either Large FFT or Blend.

    If it doesn't boot, try "(G)MCH Frequency Latch" on 333 with a 2.00B System Memory Multi. If that fails, you may have to increase Vcore and/or MCH voltage.

    managed to boot into windows with your settings, prime 95 fails in 2-3 seconds i start..

    any suggestions ?

    As detiled in my last post:

    try "(G)MCH Frequency Latch" on 333 with a 2.00B System Memory Multi. If that fails, you may have to increase Vcore and/or MCH voltage
    If temps are ok, you should be fine to go up to at least 1.40V Vcore, the chip is rated to 1.5V max. As you increase Vcore, increase CPU Termination too. Keep CPU Term lower than Vcore, eg if you're setting 1.40Vcore, set CPU Term to 1.36V.

    I'd try changing RAM multiplier first though. If you have a G0 stepping Q6600, you should be able to do 3.2GHz on 1.350V. Maybe not though.

    Also search this forum for ideas. There are several posts on Q6600's on the UD3P/R.
