More about what 5870 results
  1. I have Powercolor 5870 which is factory overclocked to 875mhz gpu clock/ 1225 mhz gpu clock. I managed to overclock it upto 900mhz / 1250mhz while playing a game but my pc starts freezing or the display acts weird or Windows give driver error messages when I set it higher than
    930 mhz / 1270 mhz. Though I did not yet adjust the voltages.
  2. i have XFX 5870 XXX edition, my clock is 900/1300 at stock voltages. for some reason I am unable to take it higher since it is apparantly locked there.
  3. Got a 5970, not quite the same since crappy drivers and stability issues. I can get 1050/1300 on 1.26v
  4. well if it is stable at these speeds, it frekin' awesome. how do i increase my clock further, whenever i take it higher than 900 using afterburner & apply it, it comes back to 900. seems its locked there.

    Generally, first go to ATI CCC, go to ATI Overdrive, unlock the card and then uncheck the ATI Overdrive box to disable it. Then make sure you have the config file for Afterburner set for "unofficialoverclocking =" from 0 to a 1. After that you should be good to go, however, some manufacturers have different BIOS's so you might have to flash the BIOS for advanced tweaking. I don't really know much beyond that.
  6. seems i need to do that bios thing only, they bars in CCC are locked at 900/1300. i.e. thats the maximum on the slider bars, there is more in afterburner, but when i chose a higher setting & apply it, it comes down to 900/1300.
    what issues can i come across if i flash the asus or the msi bios on an xfx card??
  7. Well to be honest, I've heard flashing a vid card BIOS can be a bit risky, but I don't know enough about that to say much. I can only suggest you try to find some guides and see if anyone has done it on your exact card
  8. You must safe your own xfx bios and change the limits in your bios then flash that back, do not use any other or you brick your card.
    Make sure you keep a copy of the non changed bios on a bootable usb stick with ati flash on it else your in trouble :D
  9. For edit a bios file you need rbe.exe ( radeon bios editor) can still not edit my posts how freaking annoying
