I have this card PowerColor AX7970 3GBD5-M2DHG. Could some one please tell me the correct BIOS to flash to get in the 650 to 700khash area. I currently get 585khash/s on all 10 cards with 1090/1500/1.111v
Cgminer -g 2 -I 13 --thread-concurrency 8192. If someone can tell me the correct BIOS I am willing to offer a bounty in BTC or DOGE. Thanks.

Back off your OC. What do you get at 1025/1500/1.111v?

So for my cards the 3 XFX HD 7970 Black edition coreclock 1000/1425, i founs a Bios sollution , And I have flashed them all.
When flashing as somebody asked you must flash with the Bios switch in position Nr 1
Pos. Nr 2 is locked, and good to have if ya screw up...
Core is then reset to 925/1375, then you have to manually overclock to 1050/1575
and i now get a hasrate of round 740 kh/s

The Bios that I used Is one which is Modified by "TheStilt" and it will 100% work on the cards that have the part number "FX-797A-TN FX-797A-TNBC v1.0"
on the back sticker..
heres a link to that Bios http://s000.tinyupload.com/index.php?file_id=73769960143386079737

It may also work for other similar cards but I dont know, but as long as you have a bios switch there shouldnt be any problem in trying, at your own risk.

Thanks for the ideas. Let me know if you can find the BIOS that will help these cards in your travels. I will send you some doge or btc.

I have 3 of the exact same cards. Just got them yesterday to begin my mining rig. So far I have only 1 card running as my motherboard is yet to arrive. as for the settings I'm running :

Catalyst 13.1 clean install. with included APP APK.
Win 7 Ultimate 64Bit
CGminer 3.1.0

Code:

setx GPU_MAX_ALLOC_PERCENT 100
"C:\Users\TV\Desktop\guiminer-scrypt_win32_binaries_v0.04\cgminer\cgminer.exe" --scrypt -u user -p pass -o stratum+tcp://global.wemineltc.com:3335 -w 256 -I 13 -g 2 --thread-concurrency 8192 --temp-cutoff 85

Now this will get me anywhere from 520-560kh/s speed on the card if I leave the card at default clocks. BUT after hours of tuning with just AMD Overdrive, I gotten my hasrate up to 660Kh/s

945-949/1575 = 650KHs
895-899/1500 = 625KHs

mem clock is set to max for the best efficiency mining and the core clock has a very sensitive line.
For example my card will get around 550KHs with 950/1575 and 650KHs with 945/1575
Because AMD Overdrive only does 5Mhz increment I cannot pin point the exact line to the 1Mhz yet.
You can play around with ur Core clock a bit with one card and try to find the line that gets u that extra 100 Khs

Since 650KHs is still probably a bit off from the optimal speed for a 7970
My next step would be trying to find more BIOS for the card but I havent started on that yet!

Can anyone recommend a BIOS (Non OC edition) that works well for an MSI 7970 OC Edition?
( R7970 - 2PMD3GD5/OC http://gpuz.techpowerup.com/14/01/16/gyd.png )

I've tried everything currently listed for MSI on techpowerup.com without much success. (http://www.techpowerup.com/vgabios/index.php?architecture=&manufacturer=MSI&model=HD+7970&interface=PCI-E&memType=&PmemSize=)

Printed on the PCB Board: "V277 Ver 1.0"

Thanks for any suggestions!

I literally stayed up all night till about 5AM trying to get this exact card to hash over 550. The bios I flashed it with was one that changed made afterburner see it as a lightnining b to get a hash rate of 650 stable. It did voltage lock the card though.

I'll be home later today and will uploaded the bios I used since I don't remember the one I got from techpowerup.

I'm having this same issue with this same (rev 1) card. Can you please tell me what bios you used? I can't find one that seems to work.

Thanks!

Any suggestions? I have the XFX 7970 Black Edition.

The card works, albeit, much more slowly than I am wanting but I can't flash to upgrade.

I used the rufus boot and when I use
C:> ATIFLASH -F -P 0 s.rom
I get the response below. (I might have used more -f flags when the simple one didn't work.)

Old SSID: 3211
New SSID: 3000
Old P/N: 113-797ATDBV32_111215SZ
New P/N: 113-2104XTHY-OB5
Old DeviceID: 6798
New DeviceID: 6798
Old Product Name: Tahiti B0 CR XT C38601 GDDR5 3GB 500e/150m
New Product Name: Tahiti B0 XT GDDR5 3GB 500e/150m
Old BIOS Version: 015.022.000.004.000000
New BIOS Version: 015.025.000.099.000000
Flash type: Unknown SPI

Write fail
0/20000h bytes programmed

Any ideas? Also what's weird is that when I started I tried to save the ROM and the info says it's 40000 in length not 20000 in length like the replacement is.

Hi

I am new here i also have the XFX Hd 7970 Black Edition 1000/1425 reference cards. 3 of them to be exact, and i am just in the beginning stages of building my very first mining Rig
I have understood these cards dont hash that great, so me too I am looking for the correct BIOS to flash them with.

I did a quick search on the "NEW BIOS" that you were trying to flash with, and I find that that bios "015.025.000.099.000000" belongs to a HD 7950 card
I dont know if that maybe is a reason for your write miss match, or maybe it is intentional. Are you suppossed to reflash the 7970 to a 7950??

If i find any sollution to my 3 cards i will post here. If anyone out there allready has a sollution,i would greatly appreciate a hint in here:)

Thank you

MSI 7970 3GB OC (Boost Edition) :

reply if interested about details

I'm interested!
I'm stuck with the Gigabyte 797OC-3GD at 530Khs. Tried flashing ~15 different BIOSes but either doesn't help or won't boot/load drivers/crashes on cgminer.

Before trying to follow the advices i wanted to ask, casue I'm afraid of doing damage..

So i have 2x Asus HD7970 dc2t-3gd5

I ve been trying to tweak all days long, but max i can get is about 550kh per card.

Now i wanted to try to flash the bios , wich one should I choose? I need to use the bios of my particular card model, or I need to use Bios from another one?

thanks!

Hi!
Sorry for waking up an old thread but I've got some problems with my XFX card....
The highest I've been able to get is around 650Kh/s but since I should be able to get over 700Kh/s I really need some help.
I got the highest when I flashed my bios to the Gigabyte one.
Need some advice

EDIT: got it up to 700Kh/s by maxing out my memclock as high as it could go and take that times 0,59 and using that as a coreclock.
Wow I'm good..
--thread-concurrency 8192 -I 13 -g 2 -w 256 --gpu-memclock 1750 --gpu-engine 1032

Great wealth of knowledge going around in this thread. Has anyone done a bios flash with an XFX 7970A-TDK 1.0? I see lots of other success stories of people flashing the TDJ version. I am stuck at 570k and have tried all the normal rounds of cgminer adjustments.

Same issue with that model card.
Has you found a resolution yet?
I tried 20+ other bios flashed on it....takes none one of them well.

Still cant flash my TDKC 1.0. Freakin sucks to be stuck at 500kh/s

I'm gettin the same thing right now.. Can't flash this bastard! Did you have any luck? I've thrown basically every command I can find at it. Not even able to flash the extracted rom.... just kicks back the same message pretty much...
