Title: HD7970 Reference Card Unlocked BIOS Post by: bitlane on May 14, 2012, 09:54:29 AM Does anyone here have an UNLOCKED BIOS for a 7970 Reference Card ?
How do I know if I have an unlocked BIOS ? If you are a Windows Miner and can make Voltage Changes to your 7970 using CGMiner....you have an unlocked BIOS. Some Asus Reference cards are bound to have them, as that is where I got my 5870 Unlocked BIOS (flashed my 5850 Reference Cards with) which allowed me to make on-the-fly Voltage changes to my 5850's using CGMiner. I would just like to add on-the-fly Voltage control to all of my 7970's....without needing anything other than CGMiner. Thanks in advance, bitlane Title: Re: HD7970 Reference Card Unlocked BIOS Post by: AzN1337c0d3r on May 14, 2012, 10:32:38 AM I use MSI Afterburner profiles. Is there some reason why you cannot use that?

I'd rather keep each rig as simple as possible and not rely on another point-of-failure. Remember, this is Windows....LOL Title: Re: HD7970 Reference Card Unlocked BIOS Post by: Graet on May 14, 2012, 11:59:18 AM k, well
I have found through trial and error (and help from ckolivas) that my 7970s run below stock voltages even though cgminer is still reporting stock. How do I know this? plugging system into a wattmeter and comparing power draw at different clocks Finding that if I do not put --gpu-vddc <number> in my .bat cmd line (ie stock voltage) the cards overheat and crash within 10 seconds I have also an issue with one card running consistently hot (thanks no advice needed, the supplier doesnt care , told them I'd see em when it fails) it took quite a while and I'm not sure if its just a problem with the sensor, but with this command line I get 702Mhash per card cgminer.exe -o http://eu.ozco.in:8332 -u graet.20 -p p -o http://us.ozco.in:8332 -u graet.20 -p p -I 9 -k poclbm --auto-fan --gpu-engine 1100-1180 --auto-gpu --gpu-vddc 0.87 --gpu-memdiff -150 --temp-target 75,95 --temp-overheat 95,115 without those temp settings the card was being throttled by cgminer I found system with 2 card enabled: base measurement 97W idle 652W hashing with only --auto-fan --gpu-engine 1100-1180 my command line above 102W idle 620W been running stable at 702Mhash/card for 5 days (power outage killed my uptime :P) I have been told this is impossible - meh, I believe my eyes ;) cards GDDR5 Overclocked HDMI Radeon GV-R797OC-3GD 7970 I don't do ref cards - 3fan gigabytes are my fav - hash well, run cool and most importantly quiet :) Title: Re: HD7970 Reference Card Unlocked BIOS Post by: bitlane on May 14, 2012, 12:14:08 PM Well, this setup below is drawing 1,000W at the plug (well, at the UPS as it tells me in it's fancy little LCD window).
- 4x Gigabyte Reference HD7970 @ stock voltage, 1100mhz GPU, 950mhz Mem - Gigabyte X58 I7 Motherboard - Xeon 5506 80W Quad Core CPU - 4GB DDR3 - SATA HDD - Win7 x64, CAT 12.3 **output from my API Monitoring App (a little different from standard CGMiner output, but all info is there) Using: -I 9 --auto-fan --auto-gpu --gpu-powertune 5 --gpu-engine 1000-1100 --gpu-memdiff -150 --temp-target 69 Code: GPU 0: 67.0C 4201 RPM 70% Fan | 1100 Mhz GPU 1.17 V 950 Mhz MEM | 652.0 / 652.7 Mh/s | 99% Load | A:393 R:0 HW:0 U:9.24/m I: 9 I am about 100W or so over the power draw I really wanted to be at with this setup.... Title: Re: HD7970 Reference Card Unlocked BIOS Post by: Graet on May 14, 2012, 12:48:08 PM have you tried setting --gpu-vddc ?
I just started at 0.95 and eased it down till I found minimum stable voltages, that allowed me to up the clocks on both cards to run stable :) also --temp-target 69 will make your fans run harder than the default 75 - and that uses more power too (unless ambient temp is quite low of course) Title: Re: HD7970 Reference Card Unlocked BIOS Post by: bitlane on May 14, 2012, 12:51:48 PM have you tried setting --gpu-vddc ?

I confirmed this by setting it (-gpu-vddc) to an unreasonably low setting to force a lockup, yet everything stayed running fine and no voltage change.

sorry I cant be more help Title: Re: HD7970 Reference Card Unlocked BIOS Post by: bitlane on May 14, 2012, 01:02:42 PM I have a couple BIOS files I am going to try out.
I found an 'Extreme Reference' BIOS straight from ATI as well as an Asus BIOS for Reference cards, said to be unlocked. I have 'get out of jail free' cards here (thank you dual bios switches...lol) so I might as well take advantage of them and play. I appreciate your help. bitlane Title: Re: HD7970 Reference Card Unlocked BIOS Post by: Graet on May 14, 2012, 01:37:35 PM I have a couple BIOS files I am going to try out. welcome - and <3 that switch :PI found an 'Extreme Reference' BIOS straight from ATI as well as an Asus BIOS for Reference cards, said to be unlocked.

Title: Re: HD7970 Reference Card Unlocked BIOS Post by: ChanceCoats123 on June 28, 2012, 06:57:59 PM If you've ever heard of Gpu-z, you'll also know that they have a bios upload feature which allows the user to send a copy of their bios to their database... and then for others to download. ;)
Here are all of the Asus 7970 bios they have uploaded: http://www.techpowerup.com/vgabios/index.php?page=1&architecture=ATI&manufacturer=Asus&model=HD+7970&interface=&memSize=0 (http://www.techpowerup.com/vgabios/index.php?page=1&architecture=ATI&manufacturer=Asus&model=HD+7970&interface=&memSize=0) The bios you're looking for may or may not be there. Hopefully you find what you need. Title: Re: HD7970 Reference Card Unlocked BIOS Post by: ummas on July 17, 2012, 07:59:20 PM Op
Did You find any working BIOS whith allows You to change voltage in Cgminer? Did You try GHz edition BIOS as well?

After flashing that bios I can't seem to get the original or any other bios to flash to my card, I had to use the dual bios switch for now to get it back to mining.

What's the status on flashing your GPUs?
