Re: Low hashrate on 7970 scrypt? Under 700Kh/s? Here's what to do...
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.
This is not true, with the F62 BIOS it will go down to 0.95v if you set --gpu-engine 700 in cgminer. At 701 it will be 1.2V and at 1001 it will be 1.25V
Hi,
where did you get the BIOS, and did the card come with a single or double digit BIOS?
I'm trying to get mine up from 530Khs, flashed around ~15 different BIOSes but either doesn't help or won't boot/load drivers/crashes on cgminer.
running at a stable 725 kh/s with 82temp still in case!!!
If anyone needs a little help on tuning a GIGABYTE 7970 give me a holla
Hi there!
I do.
Got the Gigabyte 797OC-3GD rev1, and doing only 530Khs with official BIOS, F3.
Would you mind sharing what BIOS did you settle on and what settings?
Thanks!
Without any overclock, a 7970 should be getting more than 520 khash/s easily. I have a 7950 boost (925/1250) and I'm getting more than 520 khash/s.
I know. It's a known problem with some cards, especially GHZ edition. mine is 1050/1500 stock, and is only 500-520kh/s.
Lots of people solved it by flashing non-GHZ BIOS, but I can't find one that will work with my card
Hopefully someone with the same card will share a good BIOS for mining.
Try what?
The poster did not say what BIOS he flashed?
As I mentioned in the OP, I already tried a bunch of BIOS from different cards/mfgs but no luck yet.
Hello!
I'd suggest trying playing with different switches in cgminer. I have 2 280xs which are basically 7970s. Here is what you should try: --gpu-engine 1098,1084 --gpu-memclock 1500,1500 --thread-concurrency 11200 -I 13. First i set gpu-memclock to 1500 which helped me to get above 600 then, thread concurrency, then set gpu-engine clock and try a few values between 1050-1100, and wait a few seconds for the hashrate to stablize. Hope this help, i don't think flashing new bios will help. Also try it on a fresh windows, it helped me a lot too.

Thanks, but I systematically went over a lot of combination of switches, cgminer versions, driver versions, SDK versions.
I tried it on linux just to be doubly sure.
On the other hand it's been confirmed that XFX and some other cards have mining crippled firmware.
Some folks can flash their cards and get normal hashrates ~700-750kh/s.
I'm just unlucky as this is a non-ref design.
Hi,
might as well do my introduction with a proper post.
So I got an XFX 7970 Gigahertz edition, double dissipation. non-reference board with two dvi, hdmi and two dp ports. No bios switch too.
The sticker on the board says: 797G-TD FX-797G-TDF VA1
GHZ DD RADEON XT2 1050M WITH BOOST
Atiflash product name: Tahiti B0 XT2 C38620 GDDR5 3GB 500e/150m
BIOS P/N: 113-797TDF70-101
BIOS ver: 015.022.000.001.000000
BIOS date: 07/18/12
No matter how I configure cgminer I can only get ~520kh/s out of the card.
Reading around, it seems a different BIOS would help, so I tried a bunch with crappy results.
None of the XFX ones will even boot, gigabyte won't load drivers, sapphire will load drivers but crashes. All were different 7970 BIOSes.
I tried one xfx r9 280x but that one wouldn't even flash for some reason (flashing failed).
I welcome any suggestion as to what BIOS might work for this card.
