    We'll see if it's benchmark stable, but it's prime stable still :D

    <3 P6T, Thermalright Ultra Extreme and Corsair Dominator memory.

    20 x 200, how ultimately elegant!

    BTW, does dropping the multi by 1 or 2 give good overhead for the FSB core frequency? At these high multiplyers it could be worth it quite easily...

    Not really, unless you're going for memory bandwidth, but it has that in oodles anyway.

    We're finding that QPI/Uncore frequency (like AMD CPUs) is the limiting factor and needs to be clocked back a bit.

    how easy was this O/C? I think I might get a 920 and put a mild O/C but I don't want an expensive or monstrous cooling solution. Think it could be stable around 3ghz+ with a very quite air cooling solution?

    I think 3Ghz would be very tame - although I don't think you'd get quiet cooling without a chunk of copper heatpiping and alu sat on top of the cpu.

    Piece of piss if you know what you're doing.

    We *do* have a monstrous cooling solution though (Thermalright Ultra Extreme).

    I have never overclocked before, but I am really loving the price for performance of the i7 920. Would it be fairly easy for me to overclock for the first time using this processor?

    How hot is it running at those kind of speeds?

    how close are you to the TDP OC limit of 130W?
     
  14. Guest-16

    Guest-16 Guest

    Easily over 130W. It's a hot office (we can't turn the heating off) and I'm idling at 45C on a TRUE. I've had it running at 80C and it's perfectly stable though.

    This is at 1.35V mind and on an open air test-bench, no case airflow. I've been talking to some people elsewhere overclocking them today and a lot of others have had good results on water - 45C load at 4.2-4.4GHz.

    It's a piece of piss to overclock - I'm writing an article for later in the week to walk you through it with 2 boards. We decided to do a more complete look than including OC figures today because of the popularity of our previous Q6600 OC article/guide :)

    MMmmm... 4 cores 8 threads.... cheesecake...

    Think I'll wait for 32nm on these babies, hehe. :)

    WOW!
    that's pretty impressive. And i thought my 800MHz OC on my E6600 (to 3.2GHz) was solid for air cooling.
    So much for all the AMD naysayers going "No... you won't be able to OC these puppies..."...

    Well it's the Havendales that worry me to be honest, although having experienced the overhead of QPI I'm in more favour that they should be good now. Depending on whether the Uncore area with its new components survives the stress of overclocking.

    hehe yep and thats with first rev everything, in half a year they will go a few hundred mhz higher due to better cpu's, chipsets, bios versions.
