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?

Check out some of my music, and if you like it, please donate!

Use MSI Afterburner or this.

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.

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.
