    Hi EEEEEEE


    I have BFG GT 220 1GB DDR2. So I overclock too too much

    Core clock from 625MHz to 800MHz
    Memory clock from 500MHz to 650MHz


    before overclock

    After overclock

    [​IMG]


    before that overclock I change "heat skin"

    BFG heat skin that built in the card is not good for overclock, because when I play games without overclock such as Crysis temperature was at max 67-69c. Other games less between 53c-62c

    So I take it off and I put another one which is XFX HD 4670 DDR2 Then I overclock it


    So I tried to play around 3-4 hours and temperature was at max 49c

    That only when I play Crysis, other games less between 43c-47c

    Fan speed 50 it's not change, just 50


    Now my question is

    Is there any problem with this overclock? I mean such as voltage ... etc.

    temperature is very good about 49c. So is there any thing else



    Thanks all

    Does it BSOD, Artifact, or driver fail? If not then you should be fine.

    Yes Every thing is Fine . When I play nothing crash or happen.
    Thanks

    BSOD??!

    When I was watch some photo cams a message that graphic card stop working, but that happen about 1 second and return without any frizzing or close my works
    but i think that is not a problem because I have about 1000 driver in my PC.
    and that problem cams as routine before overclock.

    Thanks
    ********

    What I mean is That make any problem in future?

    You know I don't want to kill my graphic card:(

    i think it is too much overclock of the memory.

    Do benchmarks and see if it really makes SENSE to do extreme overclock. Search for a "sweet point" where performance is higher but no problems. Also check temperatures of course!

    I do benchmarks by "MSI Kombustor"

    temperatures Max 49c . Fan speed 50%


    I have 5-6 FPS more
    MIN= 19 ........ MAX= 26 ........ AVG= 23

    but it's very good

    I can play


    - Cryiss on High ( except shadow medium ) 1366 * 768 smoothly
    - BF : BC2 every thing max 1366 * 768 smoothly

    and other games


    but i am afraid if that good or not

    Wow I can't believe a dude that just registered got the nick "Mohammed".

    If it's not showing wierd "artifacts" on screen or getting really hot (90C?) then you are fine.

    Yeh bro it's amazing world [​IMG]

    When I play 4hours Max hot was 49c

    also there is no artifacts showing on screen



    Is that decreases graphic card lifetime ?

    Well, Mohammed is the most common name on the planet so I can't believe no one registered it here before 2012. I would not be surprised if there were a bunch of others with different spellings and with numbers but I'm not about to spend the time to look.

    No most modern graphics cards are designed to run between 75 and 100C under heavy load. We will be using our brains as GPUs long before this thing were to die from voltage and heat.

    That's very low (which is great).
    Every card I had reaches 75 - 80c and that without overclocking!

    With the exception of the 8800GT.... that used to reach 95c. And it's still running fine and subjected to heavy daily gaming in my brother's pc.

    Are you watercooling?

    As long as you are not giving the card more voltage just continually bump it up. There is no way to damage the card at all if you do it through software as you can go into a Windows safe mode and remove the software utility, which would in turn remove the overclock.

    Hi thanks

    No, I am using XFX heat skin on my BFG :D
    but before that I used Arctic Silver 5 Thermal



    Yes that what i am talking about "voltage"


    because when I flashing my other ATI graphic card I saw there is different value under voltage value

    for example: XFX Radeon 6850

    [​IMG]

    so there is different Value


    So my card was 625MHz

    now it's 800MHz, so may it need more voltage. but I don't know how to measure that
