Title: Overclocking CrossfireX - it just won't work! (3 x 5830) Post by: checkmate on July 05, 2011, 01:03:34 PM Hey there,
I'm currently using my three 5830s to mine. I have a Antec 1000W power supply, 4GB RAM, AMD Athlon X2 and a ASUS board. My fourth 5830 is in my normal PC - I sold my old NViDiA card, so the 5830 is used for gaming and mining (when I'm not gaming). I can overclock the single 5830 to 990/300 and let it run stable for days. No problem at all - I can use MSI Afterburner, ATI Tray Tool or Sapphire TRIXX - it does not matter. But for the CrossfireX config, I get problems while overclocking - it only works with OVERDRIVE (which is limited to 900/500). When I use any other tool I mentioned above, the computer freezes instantly if I hit apply - even if I only OC to 810Mhz (800Mhz is stock). Yes, I ticked the field where it says "Multi-GPU blabla" and I googled my ass off - I practically have no ass left. Seriously. Now; is there any possibility to overclock those three bastards without 1) Flashing my BIOS 2) Using Overdrive? Any help is greatly appreciated!

Does that imply that overclocking will work when I get my dummies? Title: Re: Overclocking CrossfireX - it just won't work!

EnableUnofficialOverclocking = 1 UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 AccessibilityCheckingPeriod = 0 I also recommend dummies.

Yes, I did. It froze after hitting the apply button... like always. Title: Re: Overclocking CrossfireX - it just won't work!
