AMD release HD 7970 Ghz bios upgrade for Reference HD 7970 !! - Page 30

post #291 of 390
Hey mates.
I might have just found a solution here as I broke my 7970 trying to do this, but gigabyte has a jumper/switch for dual bios? what do i do to flash the old bios back? either directly through the switch or with my old bios saved.

It seems I've given a bit of a rush last night when I just received my Gigabyte Ati Radeon HD 7970 OC (1ghz stock) , and tried flashing to make it into GHZ Edition (for boosted memory from 1375 to 1500)

Now, it won't boot or anything, I've tried all possible programs to flash, it also ruined both Windows 7 and Windows 8 for me, I'm trying to reinstall W7 ultimate x64 now, if there's any possibility of flashing a card that isn't recognized thoroughly (not in gpuz) not in the 2 gigabyte software - easy tune something and gigabite bios, and it won't recognize it (the bios tab grays out) , so does on the other program. in W8 ati flash ati winflash and other software apparently aren't compatible, and I don't know exactly how to make dos work on the UEFI bios motherboard Asrock Extreme4 z77. Also running a SSD raid (2x180GB Intel s-ata 3)

Can you guys please advise? I will install W7 now and need a windows or dos solution afterwards, as thorough as possible, I've just spent my 2 salaries on that videocard, so I can't take no, it's broken and also lost its waranty for an answer. I have saved the original bios (stupid me, at least that).

Thing is I've done several bios flashes so far and other 'risky' things, but all turned out just fine, so didn't know that if it wasn't a reference card would turn this way....

Please advise, I'd be a thousand times grateful.

John.

Flip the switch, and the old bios should work. That's all. If you want to flash the old BIOS, you'd have to keep the switch in the bad position and blind flash. Hope you have a backup. Otherwise you'll need to find someone with the same card to pull off and give you the stock BIOS to flash.

Is the Ghz BIOS worth it if you OC your 7970 card anyway? Like I don't think it's worth the trouble for my to do it, and i may brick my card so better just to leave it with vanilla bios? I think mine has a dual switch, but still. If i fry one of my switches then i will only have 1 switch? (if that make any sense)

There is next to no risk in this if you have dual BIOS and make backup before starting. If you mess one up, you can boot with the other BIOS. Once you're up and running, just flip the switch to the damaged BIOS and force flash it to original. I prefer the bootable USB + AtiFlash way, just because it is less prone to failure and not dependent on your OS.

Edit: One more thing: always do the modifications on the BIOS number one. BIOS 2 is the protected fail-safe which you don't want to screw up by force flashing.

no manual overclocking is still the better option. you can choose optimum voltages and get best perf and at the least possible power because of careful voltage tweaking. the HD 7970 Ghz BIOS applies a fixed 1.25v and causes power, heat and temps to rise significantly.

and i was going to use this bios http://www.techpowerup.com/vgabios/125405/Gigabyte.HD7970.3072.120716.html

your card is already at 1 Ghz. Why do you want to flash the Ghz BIOS. Use Sapphire trixx or MSI afterburner and manually overclock with voltage tweaking. once you have found out a good stable overclock and setup a custom fan profile to keep the chip cool, save the profile. Load it up when you play games. the rest of the time leave everything at default settings.
