    When news first surfaced of this board i thought...hmmm something i need for the multimedia machine.....i better give it a crack. Next thing you know guys are saying i should overclock it etc so why not :D

    I sat down putting it all together and MSN lights up with youngpro going bananas over the board......i'll let him show off the clocking he did with his Core i7 860 later EEEK

    Suffice to say this little pocket rocket is exactly that. It's dead easy to OC and pushes the new Core i5 655K chip hard. I thought i would crank the voltage and do some 3DMARK06 CPU test runs for a laugh. I started off at 4.2/4.4/4.5/4.6....im thinking wtf this is nuts.......4.7/4.8/4.9 :shock: faints. I left it to finish a 32M Superpi as well...didn't tweak obviously as it was single channel on w7, just wanted to see if its stable with pi too

    Hardware setup:
    • Gigabyte H55N-USB3 mini-ITX (F2 shipping bios)
    • Intel Core i5 655K Unlocked CPU
    • Intel Core i7 875K Unlocked CPU
    • CoolerMaster Hyper 212 Plus CPU Air Cooler
    • Corsair GTX2 Dominator (had clearance issues so just used one stick)
    • WD 600GB SATA3 VelociRaptor
    • MSI HAWK 5770 PCIe Graphics Card
    • Corsair HX620 PSU
    • Windows 7 32bit

    5247MHz validation on air EEEEEK

    I'd love to see what's prime stable. That's awesome, though. I don't know how it's using that cooling, but that's pretty bloody lucky. Got any pics of the board with the cooler and both fans on there?

    Nice overclocks Dinos, I would like to see the board with some mosfet cooling for 24/7 overclocks. I would've have waited for this board if I knew it was coming out but already purchased a ECS H55 min itx motherboard...:lol:

    lol. That's still a lot of volts, though. What sort of temps does that entail?

    I've started priming about 2.5 hours ago with 4.4GHz bumped it to 4.5 at hour mark and 4.6GHz at 1.5hour mark

    I just bumped it to 4.7GHz and it's still going :cool:

    With an inch of thermal headroom to boot. Damn these chips look good. I'd love to see what the i7 can do. :D

    Godd luck.

    What sort of temps are the mosfets running at?
    Has Gigabyte specified a TDP limit?

    i couldnt measure the temps as it was too narrow a place to stick a probe and i stopped priming now

    i'll try mount one when i put an i7 CPU in there for testing

    TDP limit i dont know mate but it supports the i7 CPUs

    What sort of i7? The K? Because I've heard the unlocked i7s aren't any better than the 860s, whereas the i5-655k go a lot further than their locked counterparts.

    In-ear infra-red thermometers work ok

    Bought the cheapest on eBay (ex Hongkong). Useful for everything. HHD, IN & OUT FANS, GPU, MEMORY, CPU, etc.

    In winter, ceiling is 3 degrees warmer than floor, easy to detect outside air temperature leaks. On my netbooks & notebooks, the effectiveness of the fan or fanless coolers. Easily obtained AA batteries last a very long time.
