About Trixx and voltage on Sapphire 5850 Xtreme

Hi everyone.

Well, I got this card, an HD 5850 Sapphire Xtreme with an i5-3330 and a GA-Z77.

So I'm tryng to OC the card... the default voltage is 1088 with 725/1000 and 0.950 with 2d mode. Ok, the problem is when I raise the voltage with Trixx (MSI is locked for me and can't unlock it in the options or editing the cfg, tried everything) the voltage doesn't fall back to idle (0.950) and I need to restart or suspend the PC so I assume Trixx doesn't respect the Powerplay, I want to know if there's something I can do to fix this, I was thinking about flashing or editing the bios but I don't wanna brick my card, I don't even know how to flash it.

Greetings!

TRIXX usually respects Powerplay.
But it also has a number of other issues, like setting correct voltage after Windows wakes up from sleep.
I struggled with it for a while, and then flashed my edited BIOS with ATiWinFlash and VBE7. There should be a nice guide somewhere around here. Just make sure you account for Load Line Callibration! The voltage that is shown in TRIXX is NOT the actual voltage on the GPU. Also, sometimes the values that you can read from the BIOS and the default value in TRIXX also differ. Make sure you double-check everything with GPU-Z, it shows the actual voltage after LLC.
