OCing 5850 past CCC limits?????????????

:hello:

I want to OC my Gigabyte HD5850 past the limits of CCC (catalyst control center), As I understand it there are a few programs for this.

I've tryed ATi Tool which tells me that no kernal driver is running, I have no idea what thats all about.

AMD GPU Clock Tool says there are no valid devices found! :pfff:

Rivatuner Doesnt support ATi 5850's yet.

And MSI Afterburner won't let me go past the same limits as CCC (775/1125) :non:


So I'm at a loss at the moment :cry: . Anyone have any suggestions on how to fix AMD GPU Clock Tool or recommend a similar program, I'm using Windows 7 64bit.

Thanks for any help.

  1. Your going to need to flash it to an asus unlocked version or an MSI version.

    Here is a link to that bios:

    Instructions on flashing the bios:

    Also heard that GPUTOOL may be able to overclock it without flashing the bios.

    Hope that helps.
  2. Your a legend overshocked, But if I kill my shiny new card I'm blaming you :D

    I'll let you know how I get on
  3. Hehe...

    It should go fine, if you run into a problem then just flash it back to stock.
  4. ^Nice find

    Woah worked a treat, after allowing myself complete control over the file.

    Just cracked 24K on 3DM06 :) :sol: How cool I'm I ( :non: dnt answer that)

    Thanks alot +100,000,000,000 :lol:
  6. does you card still downclock to 150 and 300 or something for "power saver"? doesnt that reset and mess up all your settings? does gpu-z still say that crossfire is enabled?
  7. did you end up flashing the new bios? howd that work? does the new bios stop the power saver thing that kicks down the frequencies? im trying to do the same thing but im pretty confused and angry lol, not meaning to hijack your thread
  8. glad it worked out bro. I always flash my cards (;
  9. @ uRSALOG,

    why are you so concerned about disabling throttling on your GPU?, my 5770 is overclocked to 960/1445 and it still throttles and it’s not a problem b/c once a game or gpu intensive app loads it jumps up to my specified clock settings. so if your not using a gpu intensive app why would you want your gpu to be clocked so high?
  10. ^To waste power and produce heat... Duh..
    Jk
  11. lol overshocked just lol

    Im only using 1 card, so no crossfire here :(

    And yes it does still throttle down. As I type this my card is at 157/300

    I didn't flash my card, just fixed AMD GPU Clock Tool so that I could go over 775/1125mhz Simples.

    Claim down man...... :o

    :pt1cable:
  14. i gots 2 and yes wating energy is an obssesion of mine, i loveee it and im gonna do it and not you nor ccc can stop meee!, ty for replying to me anyhow :) grats on your success
  15. oh and one lasst question, whad u set your voltage to to overclock your thing? is it pretty stable no artifacts with 3d mark? *** that was like three questions, what a fail, you may answer only one if you like but all three and ill /love you forever
  16. http://service.futuremark.com/home.action;jsessionid=FBA785B7C30F8E638F09D5745969B743 overclocked both cards to 999mhz core and 1205 memory @1299mV 27542 3dmark06
  17. also interestingly enough the high overclock seems to have knocked off the power regulation throttling YAY and the cards never went over 59 degrees celsius with my water cooling system
  18. Nice mate, im extremely jealous of your CF 5850's, BTW ive only OCed my card to 800/1125 no voltage adjustment here.

    BTW im on stock cooling
  19. so i ran crysys a bit and i noticed some slight artifacting in the sky so i messed with my settings some more, now artifact free yay and i overclocked it some more new stable settings 1002 core 1250 memory @ 1.32v pretty high dont recommend it for air cooling but just to let you know it works good on my sapphires if you ever decide to get another in the future or w/e :) my watercooling doesnt let it go past 59 under load still so im happy
  20. thisll be my fianl point so i ran furmark and it it chewedup and spit out my settings (not to mention crash windows) so i went back and after much fiddling final stable settings for sapphire 5850cf are 1162mV 943mhz core 1201mhz mem. i am noticing that i have to open up afterburner on startup and sed hit apply on the settings because on the second card theyll reset to the underclocked sets 725 1000 and it will throttle, make sure you open up gpu-z before you apply them because apparently if you apply them first and then open it up then itll reset it again, and youll have to apply it again and then itll stick. i guess its a bit of a hassle to have to set them up everytime you startup but idc ill keep doing it
  21. Thanks for the advice, glad you found a way to OC your CF 5850's
