Keep in mind that Trixx can only overvolt/clock a pair of cards in CrossFire.

MSI afterburner would let me change clocks, but not voltage edit.

I suppose trying RBE wouldn't be a bad idea, or make some custom VCCD profiles in ATI Tray Tool.

I have been running my Sapphire 5830's overclocked at 1000/300 for a couple weeks with no issues.

MSI Afterburner isn't working for changing core voltage on 5830 and unfortunately I am hesitant with the other as it cost BTC and has not been tested with my card...I see he offers refund so I may try it but does anyone have any other ideas?
Make sure you've set UnlockVoltageControl = 1 in the MSIAfterburner.cfg file.

Hi all, I have a pair of radeon 5830's mining at about 600mhash/s. I was able to overclock the first card using Sapphire Trixx to 1020mhz/1.23v, however, it won't modify the clock freqs on the second card!

Does anyone know a solution for this? The program states that you should use Crossfire if you want to implement an overclock on both cards. I tried crossfire and even with crossfire enabled the OC is only on the first card (confirmed with GPU-Z). Who can help me get this OC working and hopefully hit 700 or 800mhash/s by the time I'm done tweaking it?
