steppings are AXDA1800DUT3C 41F6972L30342 SIXIB0334mpm
Anyone have anyidea what this thing can do?

    1.53, possibly higher. ;D

    It's a DUT3C, so don't get your hopes up for 2.3GHz or higher O/C's. Some people have gotten up to 2.2GHz with DUT3C chips but I think those are few and far between. 2GHz wouldn't suprise me though, but it wouldn't surpise me if you couldn't reach that high either.

    I have a DUT3C.
    Here's the full stepping.
    AXDA1800DUT3C 9583596260058
    JIUHB0306UPMW

    It does 2.25 (225x10) at 1.9V at present.
    Cooled by Thermalright SLK-947U w/Tt Smart-Fan II
    Dunno if I can take it a bit higher, heat is beginning to be a concern.

    Maybe I will swap it for a Barton 2500+, locked or unlocked?

    BTW: It did 2.0 GHz easily, I upped the voltage in BIOS (NF7 undervolts) to 1.7V. (1.65-1.67V) IRL.

    2.2-2.3GHz is what I'd predict. That's what my 1700 JIUHB DUT3C does...

    Same here, although it takes 2v to hit 2.3.

    I'd figure that would be the same for me.
    It does 2.25 at 1.9V barely.
    I don't think I can push it to 2.3 GHz below 2.0V

    I need an unlocked Barton, I need an unlocked Barton. :eek3:
    Oh dear I've gone mad. ;D

    At what vCore and what HSF combo?

    a vCore over 1.8 (definitely 1.9) concerns me much more than the few extra MHz I might garner from it.

    a2j, 2.3 at 1.85v with an SLK-800/SF2 on an ASUS A7N8X Deluxe rev. 1.04. I haven't tried it in my NF7-S, since I've got a JIUHB DLT3C 1800 in it now.

    nm then, i wont oc it, but its a possibility ill be getting mushkin lvl II, and a thorton ( depending on how they overclock).

    What a shame.
    It should hit 2.0 GHz with only a minor increase in Vcore.
    I upped the voltage 0.1V (IRL 0.5) above the standard 1.6.

    I used 200x10 (FSB/multiplier)

    hmm, are you sure? cause if it will ill put it in my main rig and put my 3000+ in my server. :bigggrin:, but i want to be certain. Do you think a stock 3000+ heatsink and fan would be enough to cool it at 1.7v? cause i may just leave it in my server if thats the case.

    Well, my 1800+ wont even hit 166 fsb at 1.7, so i think it may be a bad overclocker, or it may be my nf7-s.

    That's a bad OC.
    Maybe one of the Guru's will stop by to help. :)

    Stock fan should be sufficient at 1.7V.

    When I received my 1800+ I went home.
    Put it in the motherboard, fitted my Tt Silent Viking (big Al cooler w/ copper insert and "silent" fan)
    I booted into windows at 2.0 GHZ at standard volt 1.6 (IRL 1.55V).
    I tried running Prime 95, it failed after a couple of minutes.
    I upped the volt to 1.65 (IRL 1.6)
    It still failed Prime95, it only took longer. ;)
    Then I upped the volt to 1.7V, ran Prime95 for several hours with errors.
    The cpu was running at 2.0 10*200 for several months (7-8 months to more precise)
    I didn't have any issues at all related to my OC.
    My problems showed up trying to get even higher. ;)
    2.25 225x10 at 1.9 isn't the best for the temperature, but it'll do.

    Actually I was surprised how easy it was to get from 1.533 to 2.0 GHz.
    The cpu has never been running at 1.533 GHz unless I have been resetting CMOS. ;)

    Have you checked that the cooler makes contact?

    See what 1.75v can give you. Also, what is your FSB/RAM ratio set to? If you set your RAM to run at XXX when the FSB was set to 133 and then upped the FSB to 166 w/out adjusting the FSB/RAM ratio you might be running your RAM much faster than it's able to handle.

    Uh-oh it isn't a JIUHB it's a SIXIB, whatever that means for the OC capability.

    The heatsink is in contact, and i had the ratio set to 3/3. I upped the volts to 1.7 and tryed to get 166 and that wouldnt even do it, so i think the chip is pretty bad at overclocking.

    Most DUT3C chips are.
