I think I am ready to flash my bios but need a little help. I have a Gigabyte HD 7970 3072MB GDDRS and have tried everything but no luck getting past 550 Kh/s via scrypt. I am thinking my BIOS may be too old on the card as this is my current stats on windows 7: Display device : AMD Radeon HD 7900 Series on Tahiti GPU Display driver : 9.14.10.0969, Catalyst 13.4 BIOS : 015.022.000.004 GPU: Gigabyte HD 7970 3072MB GDDRS - GV-R797OC-3GD Looking at http://www.techpowerup.com/vgabios/index.php?manufacturer=Gigabyte&model=HD+7970 there seems to be much newer ones although I have never flashed a BIOS or anything for that matter so maybe I am wrong? My current settings are : setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -w 256 -g 1 --thread-concurrency 8192 --intensity 13 --gpu-engine 1100 --gpu-memclock 1500 --gpu-fan 100 -o http://mining.usa.la.hypernova.pw:9332 -u worker.1 -p xxxxx I have tried -g 2 and every time it drops dramatically down to 380 Kh/s from 540 in -g 1. I have also followed the ReadME file for Cgminer and my ThreadConcurrency speed came out to be 22400 but have read to use 8192 and see no difference. So at this point I am thinking a flash of the bios will be the way to go. What do you think? Thank yoU!

color 0A setx GPU_MAX_ALLOC_PERCENT 100 cgminer --scrypt -o pool -u user -p password --auto-fan --gpu-engine 1008,1008 --gpu-memclock 1675,1675 --thread-concurrency 8192,8192 -I 13,13 -g 2 -w 256,256
make this .bat file you wil get 712 and use pc also

really digging the green color =D but the result is a 390 :/ Still not sure why when -g 2 is changed to -g 1 I get 540? still way below what I should be getting.

setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -w 256 -g 1 --thread-concurrency 8192 --intensity 13 --gpu-engine 1100 --gpu-memclock 1500 --gpu-fan 100 -o http://mining.usa.la.hypernova.pw:9332 -u worker.1 -p xxxxx I'm not too sure about that card tbh. The BIOS flash is not to put a more up to date BIOS on, but to put a different BIOS on which doesn't suffer from the low scrypt hashrate. As i say this is a problem with certain cards, usually the OC / Ghz editions.. Just to confirm, your card is a normal Gigabyte, not OC or Ghz edition or anything? Try the following and let me know what hashrate you get: -s 2 --thread-concurrency 20992 -I 13 -w 256 -g 2 With 1040mhz/1081mV GPU and 1500Mhz/1500mV RAM. *Edit - reading your post more closely, am i right in saying you have an OC edition card? If so then i'm pretty sure a BIOS flash to the non OC version would work. Also if anyone's interested, my 7970's use about 250w each at these settings.

Well it runs stable and gets those 760 kh/s, however the cards are factory overclocked and locked at 1.256V. So I am not sure if its good for power consumption(obviously not), tried to flash 7970TO bios to 7970OC bios and the card did not perform as good but the voltage was down to 1.171V

So then getting out of my 7970OC BIOS might be a good move? Thanks for the help!

tiny update! So i ended up flashing the GPU with the most updated GIGABYTE BIOS and am now getting 590 kh/s almost out of the box settings =D that is about 40 more then I was able to get past for the last week so progress finally made. I used the F3BIOS to flash : ATI Source BIOS Version:015.032.000.004 http://www.gigabyte.com/products/product-page.aspx?pid=4102&dl=1#biosI then went back to 13.1 catalyst and am on 2.7 SDK as when I try to instal 2.8 SDK i get something about installation pkg error fail? So the fact that I have pushed past the 550 mark pretty easily on the new BIOS means I am off to a good start right? Now to just get past 600 and maybe 7? If you think I should flash with a different BIOS please let me know as there were many to choose from and just chose the most recent. Thanks guys!

Hey, so I've made some changes with my setup. My XFX HD7970 DD can now reach 700 KH/s, and is stable at around 680 KH/s. I'm still tinkering with it, but I think it's possible to break the 700 KH/s + mark. Here is the guide that I used and a link to the bios that I used to flash the card: Here is the solution for the 7970 Ghz card. Mine is a Sapphire 7970 Vapor. Flash with this bios http://www.techpowerup.com/vgabios/127156/GigabyteHD7970.3072.120905.html635 kh/s @ 900/1580 -I 13 -w 256 -g 2 TC 11200 Thanks to asmzx for this fix. Flashing 7970 is a breeze, I'll tell you the steps I took to get it working. Flash Sapphire 7970 Vapor: Download Rufus http://rufus.akeo.ie/ or create a bootable USB drive Get ATIFlash http://www.techpowerup.com/downloads/2230/ATIFlash_4.07.htmlCopy ATIFlash and the bios to the USB drive To boot from your USB, just press F8 after you power on your computer and it should bring up the boot menu, if not keep resetting until you get it. Select your USB from there and it should boot you to DOS/ATIFlash. Gets the device ID of the card atiflash.exe -f -p 0 new.bin Use the number you got from the first step instead of 0 if it is different. Also change the name to whatever you named your BIOS. For me, I named my BIOS "new.bin". Wait until it is successful and then reboot. That's it, enjoy 630+ speeds without melting your card!

For the record, I used the bios mentioned in this quote, and my XFX 7970 DD performance went from a high of single thread 550 (I could never get >400 using 2 GPU threads) to 690 (690 using stock mem/cpu settings, but 2 GPU threads). This is the best thread ever, and I'll be sending some donations out for sure. Can't wait to tweak mem/cpu later tonight and break 700!

I ended up with 1100/1500, -g 2, -I 13 and TC 8192 even though it defaulted at 22400. Not much else is needed unless your running them in the case. If they are still in a case you may want try 1040thru1070/1475 so it does not get as hot.

After struggeling for weeks, I'm now doing 1500 Khps with 2 VaporX cards.
The BIOS flash indeed is the way to go.
Driver 13.6B2 I 13, TC 8192, G 2 Sweetspot found @ 1065/1500
This topic has helped me a lot!! Thanks!!

Hi, to refresh a subject a little bit I have 4x 7970 Sapphire DualX cards and I obviously have an issue with them. I cannot pass the 600 Khash barrier with them even on 1150GPU and 1650MEM with 1175 voltage.... Thread is on 8192, w256, I13 threads per gpu 1.... I tried to flash bios with the one from the first thread and nothing.... Then I reflashed bios with the one from the website for my card and I did it good but no change in hash rate.... So, does anyone knows what bios should I use to improve hash rate?

So, does anyone knows what bios should I use to improve hash rate? I have the Vapor-X cards and like everybody else I flashed the bios to the Dual-X and got it to 760kh. So if we're flashing the bios to the Dual-X then I don't think you need to flash the bios at all, IMHO. I think you just need to tweak your settings until you find the sweet spot. It's a tedious process, especially if it's your first mining rig.

Its not my first mining rig, but for the first time am using 7970.... I tried all the setings that I found on the internet and thats it... 590-605 Khash and not 24/7 stable....
