Seems like my card sometimes needed a few consecutive flashes - so a failed ROM error write, then try again and success and verified for both reinstalling original bios and the new GHZ bios. I just bought a cheap, but new Zalman 7970H reference card - made my HIS I thnk. Unfortunately the card has a mid 60s ASIC and so defaults to 1.175 stock and 1.200 GHZ. But intial results suggest I should be able to undervolt it. Otherwise I am going to need a aftermarket cooler. smile.gif
The original exe didn't work for almost everyone haha, even me had to do a bios flash rolleyes.gif

So, been there, done that. Flashed both of my 7970s, a couple of hours later I'm back on the stock BIOS.

The power consumption, heat and noise of this GHz Edition is so not worth it. My cards aren't too keen OCing with stock voltage, so thought the extra voltage would be nice. It's not. The reference cooler just can't handle it, at least not with high leakage chips such as mine. With the stock BIOS my upper card does 78 degrees max (auto fan@2600RPM). With the GHz BIOS I put the fan manually at 3300RPM and still the temps got to 82 degrees. That's loud as hell and still too hot for my liking.

The good news is that in principle it works. I'm leaving the GHz BIOSes in the other slot for future use. If I just happen to find myself with two nice 7970 blocks some day...

I had exact same results , my card ran cooler all around on stock bios , but i left second bios with it , becuase it is a great bios for a water cooled setup

Mr AMD, you guys going to release another version of the bios as voltage control is locked on some brands of cards?

can gigabyte 7970 windforce use this GHz bios?
post #276 of 390
I've skimmed through most of the posts in this thread, but still can't seem to figure out what's wrong.

I've successfully flashed my reference Sapphire 7970 to the BIOS posted by pioneerisloud, but I can't seem to get voltage control working properly. When I set any voltage in Afterburner, GPU-Z and HWiNFO64 tells me that the voltage is 1.137V, and as soon as I put any load on my card, the voltage drops to 1.050V.

I've set my power target to +20%, made the changes to the .cfg file and in the options for AB , but still get this problem. Does anyone have any ideas on what to try?

I got this to work on my Sapphire radeon hd 7970 OC. I used the original exe and I got rom programmin fail for 7 times in a row, which scared the **** out of me, eventhough I have a 2nd bios. After that it went through and it was 3dmark11 stable atleast and worked straight.

I would not do this without dual bios anyways, since it's always risky.


EDIT: Why can't I increase the voltage under load. I set 1263mV in afterburner, but after a 3dmark11 run I looked at gpu-z and according to it my voltage underload was 1.080. This must the reason why I can't overclock my card anymore above 1175 on core. If anyone knows a fix for this, I'd like to know!

I've tried basically everything I know. The voltage stays at 1.149V, even though I've set it very high in AB. Nothing changes it and it just keeps dropping. 1140 core no artifacts, 1150 crashes 3Dmark11 already now. I don't get it how this is such an amazing improvement although I don't have a reference card.

I think I'll just flash back to the original bios and use the second bios for daily use since with it I can get 1200/1725 easily. The ghz flash only aided memory clocks, which doesn't make that much of a difference compared to gpu clock. Hopefully there could be something I could do with this.

Aye, I've no clue why ppl use this bios either. It boggles the mind!

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.

My system has three Diamond 7970 reference boards in Tri-Fire. It would seem that if you attempted to use the BIOS file posted 06-07-2012 on Techpowerup, you then cannot flash the BIOS to the GHz edition using the self contained autoflash exe written by AMD. It will always come up with the error "Adapter 0 Invalid PC BIOS image". Even if you flash to any other BIOS first, it will always come up with the same message. It looks as through the Techpowerup 06-07-2012 "GHz" BIOS is a development/debug BIOS that writes additional information to the card that cannot be erased or cleaned up by flashing to any other BIOS version.

I was able to flash all three 7970s to GHz editions in Windows with pioneerisloud posted ROM file. You just need to use the command line atiwinflash.exe -f -p # bios.rom
Replace "bios.rom" with the actual rom name and "#" with the index of the card to be flashed (0 = 1st card, 1 = 2nd card, and 3 = 3rd card). After that all you need to do is reboot and Windows will redetect the cards.

On the overclocking front it seems that the GHz edition behaves very differently. If you attempt to overclock with MSI Afterburner alone your voltage settings will not work. I had set the voltage for all three of my cards to 1.100V, but at load the voltages were stock (1.12V, 1.62V, and 1.74V). If I tried to overclock with OverDrive alone then the voltages would be crazy high. It had the cards at 1.26V for some reason. This caused great instability at what would be otherwise easy overclocks. If I enabled OverDrive in CCC then overclocked using Afterburner it would work. A setting of 1.100V for all three cards results in 1.100V at load.
