post #144 of 390
I was bored so I tried it again. Flashed four, then tried both trixx and AB one after the other. Trixx says some gibberish like the start voltage is 1256 lol, it's not. AB reads default as 1093mv. Anyways, after doing the voltage unlock and ulps dance, both apps have max voltage at 1150mv roughly on the lowest card to 1175mv on the highest card. Subtracting my gpu vdroop, = 1178mv roughly which is about what my highest card got.

For a rough test, I tried running Heaven with clocks set to 1200/1700 and voltage maxed, result = crash. Culprit, cannot get enough voltage. With stock bios, max voltage is good for 1310/1760 in heaven. With this bios, I can't run hardly any amount of overclock.

I'm closing the chapter on this bios for me, thumbs down.

So if my aim is only to run the card at the GHZ version's stock speeds is it beneficial to do the flash?

Why would you do that for? You can run those frequencies from within Overdrive on the stock bios and drivers. There's no point in taking a risk in flashing for you.

Ok. Then I guess the only purse for this bios is to unlock voltage limits? AB now limits my card at 1125/1575, how do I get over that line?

Can someone with Sapphire Radeon HD 7970 who able to flash to Ghz share their stock bios backup here? I forgot to backup mine. Now with bios frow Techpowerup, I can't flash to Ghz anymore. And by the way guys, how to know if the powertune is really working?

XFX ATI HD7970 Black Edition 3gb ddr5 here, Flashed like a champion. Works great. I did update to the 12.7 beta catalyst as recommended.
So far working awesome, my fps has improved per the ingame FPS reader, (i.e. WOW and BF3) Catalyst does read 1050 mhz clock and 1500mhz memory.
I'm really happy with it. I'm definately tempted to get a second gpu and flashing it. haha.
