    Default Asrock z68 Pro3 Gen3 Overclock help!

    Good morning everybody,

    I'm going to buy the MB Asrock Z68 Pro3 Gen3, But I read on some internet forums that there is a issue to OC with this mainboard, related to the Vcore Setup that can't be regulated properly with this version (with the "old" Pro3 this was possible). My intention is to buy a core i5 2500k and make some OC (just to bypass 4.0 Ghz). There is some user who has the Pro3 Gen3 that can confirm me the possibility to perform OC with no issues? Which are the settings that must be used?

    Thank you so much for help!

    I'm sure you won't have any problems hitting 4.0GHz. Most problems arise passing 5.0Hz. With ASRock this may be a bigger issue as these are the budget line of Asus products. but any budget board typically won't use as high of quality components as a more expensive board and may have more issues.

    But if you're so uncomfortable with buying one that you have to come here asking for just one persons approval, then I'd say try a different model or even manufacturer. Try not to talk yourself into something your heart tells you not to. When ever I don't listen, I always have the worst possible luck.

    read lots or reviews and view some youtube videos before buying.

    Brands I've had the best luck are Asus, Gigabyte, and Biostar. But I usually get one of the top three tier boards of the companies offerings.

    Good luck

    I received a confirmation about PRO3 GEN3 overclock by one user who did it. Here are the settings for a 4300ghz stable at 1.24v (automatically taken if you set CPU ratio to 43) if someone wants to:

    CPU RATIO ---- 43
    INTERNAL PLL VOLTAGE --- DISABLED
    GT OVERCLOCK --- DISABLED
    INTEL SPEDDSTEP TEC. --- ENABLED
    TURBO BOOST POWER LIMIT --- MANUAL
    SHORT DURATION P.L. --- 200
    LONG DURATIO P.L. --- 200
    LONG DURATION MAINT. --- 1
    ADDICTIONAL TURBO VOLTAGE --- AUTO
    CORE CURRENT LIMIT --- 200
    HOST CLOCK OVERRIDE --- 100.1
    SPREAD SPECTRUM --- ENABLED
    CPU CORE VOLTAGE OFFSET --- AUTO

    Well, I will try as soon as I receive the CPU!! Thank you everybody for help

    from my asrock board and 2500k
    1.Use the autoclock settings in the uefi/bios when you get the cpu and see what happens.
    Ive never seen/heard of anyone not getting at least 4.0 straight off.Even a 2500 non k will go 3.7,you cant clock it but it does that automatically if load demands.

    2.keep going on the auto settings till you find out what your cpu will do.
    Mine topped out at 4.6 without adjustment and for all tests at 1.2v if you like to put it that way but thats not the full voltage that will be applied on bench testing..itll go up to 1.34-1.4

    3.the highest boot speed I can get using standard Asrock bios/uefi settings on my cpu sample is 4.8ghz,but its not stable at that under hard benching, it needs some uefi/bios tweaks for that.fairly minor.max allowable voltage goes up to 1.47-1.48 altho it is in the I get 4.8 at 1.2v bracket!

    4.My cpu sample will do 5.0ghz*, but its like anything else your gonna have more heat and noise and more volts, tho you could say its in the 1.2-1.3v range, it wont stay that way long if you load itand anything over your cpu sample limit say 4.2 -4.5 ghxz you will have to push volts a bit whether you use offset or fixed .

    There are sites which did/still do information on the best cpu batch nos,stepping etc for cpu's,but for general buyers what use is that .
    The majority takes what they get .
    Buying second hand or being wary cos a cpu is coming to the end of its production run..maybe
