Need help with Gigabyte 7970oc windforce edition **FIXED over 720kh now **

[sikman]

Hi Team

Got 2 brand new Gigabyte 7970oc windforce and not matter what settings I use I can't get past 550-580 per card, Ive googled every webpage and tried every combo and still no luck

I've tried these settings plus many more

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
--auto-fan --temp-target 79 --gpu-engine 1000 --gpu-memclock 1375 --thread-concurrency 8192 -I 13 -g 2 -w 256
--auto-fan --temp-target 79 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256
--auto-fan --temp-target 79 --gpu-engine 1080 --gpu-memclock 1650 --thread-concurrency 8192 -I 13 -g 2 -w 256
--auto-fan --temp-target 79 --gpu-engine 1080 --gpu-memclock 1650 --thread-concurrency 8192 -I 13 -g 2 -w 256
--auto-fan --temp-target 79 --gpu-engine 1080 --gpu-memclock 1650 --thread-concurrency 11264 -I 13 -g 2 -w 256
--auto-fan --temp-target 79 --gpu-engine 1080 --gpu-memclock 1650 --thread-concurrency 20992 -I 13 -g 2 -w 256
worksize 256, intensity 20, gpu threads 1, vectors 1, concurrency 20800
worksize 256, intensity 20, gpu threads 1, vectors 1, concurrency 20224
etc etc

Even tried all the intensity 20 settings as well.


*************************
Issue Solved, now at 720kh

1. Uninstall your drivers - use amd cleanup utility to remove all
2. Install ATI Catalyst 13.3beta_3 drivers (if that does not help you, try 13.1 & 13.4)
3. use these settings: --auto-fan --temp-target 79 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256
Ive got this added in my bat file above cgminer settings: setx GPU_MAX_ALLOC_PERCENT 100

eg:
setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o stratum+tcp://wdcpool.erundook.net:3334 -u sikman -p password --auto-fan --temp-target 79 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256

change PCI-E slot, and add --shaders 2048 at the end of line.
AND - disconnect screen or use dummyplug!

which oc programm do you use?

regards

[LittleDigger]

Got enough RAM on the motherboard?

[hope2907]

-auto-fan --temp-target 79 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256

it should get you 730

tried that and only  550kh, no monitor plugged in, remote sessions using teamviewer

560 on both cards, I dont know what else to try

Ive tried 12.8, 13.1, 13.4, 13.5beta drivers , SDK 2.8 and 2.7 as well, makes NO difference

dammmmmmmmmmmmmmmmmmmmmmmmmm

[Arkanine]

gpu load 99%? ^^

I had the exact same problem with the exact same cards....and none of the guides out there gave me anything more than 10kh difference.  But...the settings that hope2907 gave you were what I was going to suggest as well...cuz when I finally found those settings posted somewhere I jumped up to about 725 per card.  Mine are pretty much identical but I don't use temp-target....also I don't know if it is true or not but somebody on the boards here somewhere said that he didn't get any change in hashrate unless he put --thread-concurrency as the last setting.

This is how one of my bat files looks, for scrypt mining (pool stuff removed)

setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt --failover-only --intensity 13 -s 1 -g 2 --worksize 256 --auto-fan --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192

These were the ONLY settings that made any difference at all to my hashrate.

-auto-fan --temp-target 79 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256

it should get you 730

[whitedragon]

Oh ya...and I wanted to add...I feel your pain.  I spent like 18 hours messing with those cards without seeing so much as 10kh variance (580-590).  I just bought mine like two weeks ago.

[whitedragon]

Another thing you can try that I found posted here somewhere if the 1044/1500 settings don't work...is to start there, then leave memory at 1500 and change engine (within cgminer) one notch at a time and see if it makes any difference.  Each card might have a slightly different "sweet spot"...so try moving engine speed up or down a couple (1045,1046,1043)  and see if any of those help.

1044/1500 worked great for me, but maybe yours need 1043/1500 or 1045/1500...

Good luck!

Just to mention, thank you all forhelping me out

I pasted your settings and nothing changed, still 560-565

GPU load according to GPU-Z is 98%

I've spent 2 days on this and can't get it....

I went desperate and flashed my giga bios over to a sapphire and nothing > https://forum.litecoin.net/index.php?topic=2963.0

what is you rev
1.0? 2.1 or what

i use 13.3beta

[mercSuey]

I got these cards and I got 750+ kh on cgminer and oddly enough, 760+ kh on guiminer-scrypt.  my settings are nothing fancy, but here's what I do:

I use Sapphire trixx to oc.
set core clock to 1085
mem clock to 1500
leave voltage alone at 1170

and command line arguments are:

--thread-concurrency 8192 -w 256 -v 1 -g 2 -I 13


make sure to use stock bios.

Note that I get 750+ kh with one or two gpu rig....as soon as I add a third, because of psu or mobo bandwidth (i really don't know), my hash rate drop to about 740 kh for each card....I have five running on one rig.
Also note, these cards get HOT.  And that's because they vent hot air from the top and bottom and not through the sides.  So if you have your gpus in a case (ie. not open air or on a rack/crate) your rates will suffer because of temps.  Let me know how it goes.

I forgot to mention, I am runnin cata 13.1, AMD SDK 2.8, on Win8 64bit

I tried those settings and overclocked with trixx and increased 20kh to 585kh now.

I will uninstall my drivers and try 13.1

do you use those sdk that comes with 13.1 or install skd 2.8 separately?

I will shutdown and see what rev of card I got

[whitedragon]

I guess I should mention I'm running 13.4 on fresh install of Win 7 64bit with 4gb ram.  My card bios version shows as 015.025.000.007

I'm running the same bios as you, fresh copy of win 7 64bit and also tried win 8 64bit as well.

Will try 13.1, 13.3beta and 13.4 as well.

cgminer 2.11.4, 3.1.10 & 3.1.1 also tried as well

[Joerii]

Could this be a rare case of a faulty GPU ? If all else fails, I think the steps are these :

- start with an ever fresher copy of Win, a whole new copy of Win 7. Different version, like Home instead of Professional
- install everything all over again
- if all else fails, try a different GPU, send that one back.

My two Gigabyte 7970 OC cards run with the following settings:

Code:

start /D "C:\cgminer" cgminer.exe --scrypt -o poolname:port -u username -p password --thread-concurrency 8192 -I 13 --lookup-gap 2 --worksize 256 -g 2 -d 0 -d 1 --gpu-memclock 1500,1500 --shaders 2048 --gpu-engine 1080,1080 --gpu-fan 70,70

@ 743 Khash/s.

Tips:
- check real GPU and MEM speed with GPU_Z, maybe memory is not running at right speed
- use the latest CGMiner available
