Should i overclock my ATI 4770 XFX

hi,below are my pc specs,the settings on my video card are default i think,750mhz gpu clock settings and 800mhz memory clock settings..should i increase that in my catalyst control centre and will this show much improvement in my frame rates..i use a 20inch widescreen at 1600x900 and play FPS games

More about should overclock 4770
  1. will increase frame rates
    use Auto Tune in CCC to get an idea where to start
    watch your temps with the new auto tune setting
    should idle easily below 50c in a 20c room
    download MSI Afterburner (google it-free download)
    i like that program because it will show temps and frames per
    second while playing a game.
    usually you can go a little higher than the auto tune setting
    just go in small steps (10mhz)
    use something like Lightsmark 2008 (video card frame per second tester -free)
    to see FPS before OC and after OC

    great,thanks i am downloading MSI afterburner now,i will see if there is an improvement and post again later
  3. Yeah Overclocking Will Increase Fps for Sure But make sure not to clock the card max you can because gpu overclocking is not mature yet only a few people do it and make sure not to burn your Gpu.
  4. i ran the auto tune test and the gpu clock settings are now 765mhz and the memory clock is still at 800mhz,the idle gpu temp is 48c..should i start increasing both settings now?

    It is a good idea not to go max with a card
    but OCing gpu's is not a new thing
    I have been doing it for many years
    and there is alot of software IE rivatuner,ati tool etc
    that has been around for a long time

    To the OP
    amd overdrive in ccc is a good place to start
    use autotune to get an idea how high your card can go
    they usually set the auto tune settings OC at a conservative level
    overdrive also has a test feature to test your settings
    also if you do go to high then all that usually happens
    is the computer freezes and you have to reboot
    Long term heavy OCing of card will decrease GPU life
    create profiles in Afterburner
    I have one profile which is a medium OC and another that is
    a nearly maxed OC
    When I am not using graphically intense apps (games for example)
    I leave it at stock settings
    when i play games I will use the med and max profiles depending
    on intense the game settings are
    ALWAYS be checking your temps
    With full load (higher end game) you dont want to go any higher
    than about 80-85c for extended periods
    also though most cards will throttle down when temps go high
    I have had cards for years that I have OCd
    I just sold a XFX 7600GS from 2007-2008 that is
    still running fine

    what is temp in room?

    if you look at the max that overdrive or after burner sets
    it is usually withing a safe level

    what are the max settings that Overdrive lets you set?

    the max on catalyst centre is 830mhzgpu clock and max on memory clock is 850mhz,the temp in the room is 22c

    i again ran the auto tune in the catalyst control centre for a longer period of time and now its running at 820mhz gpu clock setting, and 830mhz memory clock setting,do you think this will be ok?,i did not make any changes via the msi after burner
  9. should be fine
    keep an eye on temps
    shouldnt be over 50c on idle (closer to 40c) and higher
    than 80c on load (load afterburner and watch temps during game)
  10. dont be worried if it goes a little higher than 80c but over 90-95 you have to look into better cooling
    Zalman makes some nice GPU coolers
  11. Hi,
    My 4770 has run from day one with the CCC settings all the way to the right. it could go higher but the support for the card on both Rivatuner and Afterburner, (same thing really) isnt there. Had to hack the support section in Rivatuner to add the card and Afterburner needs a couple of entries edited as well to allow un supported over clocking.

  12. I would leave it with max CCC settings myself.
    Most cards will go higher than what Overdrive sets BUT
    the amount of performance gained from going higher than
    overdrive settins is really minimal (realistally only about 5 FPS)
    Unless your going with a highend cooler or water setup than
    stick with CCC Overdrive settings.
    Though I would leave it stock and only OC when needed.
    Usually in OCing programs like Afterburner,Rivatuner etc
    you can set profiles to load when it senses 3D (games)

    i found when i ran MW2 at those settings 820mhz and 830mhz,the game froze,then i got a black screen with a message,no VGA signal detected,i thought i had cooked my video card,i simply rebooted my pc and decreased the settings back to 765mhz and 800mhz memory clock,im not real sure why that happened
  14. just use the highest stable clock, only increase small amounts at a time when testing and you will find the cards limits. also, before you start to oc anything, clean your pc from dust, make sure you have adequate ventillation in your case. re-seat your heatsink with as5 thermal paste if temps get a bit high, i would do it anyway on an older card.. there are plenty of guides that show you how to do this properly. The memory clock is usually more sensitive to making things freeze, artifacts etc than the gpu clock.
  15. I agree that setting it higher than the CCC will go isnt worth the hassle, the temps do go up markedly and the return isnt worth it. As said just use what ever your best stable clock is Auto tune has never given me anywhere near what the card can actually do stable. Find a decent OCing guide on the net and follow that. Basically increase memory clock first in small amounts untill it wont post then put the memory back to stock and do the same with the GPU clock. Keep an eye on temps while doing this.
    Your best stable over clock will be very close to what you had on the clocks separately but i usually just drop off by about 5 with each clock and have yet to have a problem.
