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

Got enough RAM on the motherboard?

-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

8GB win7 64bit

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

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.

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.

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

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

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

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:


@ 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

I downloaded trixx and tried these settings just for fun...speed dropped from 725 down to around 575 (my old range).  Seems every card is different.  But then again...different catalyst version and OS.

I got 2 cards surely they both cant be rooted. I removed one card and tried that as well, no go

will try setting from magnet

Thats is crazy, I've got 8 PC's right here, 5770,6850,5870,6950,6970,5970,5830 and 2 x 6990 and all those cards were configured within 2 minutes and running withing 5% of max speed according to the HW comparison websote, but these 7970's are fucked to put it mildly..

And the Winnder is "WhiteDragon"" tried those exact same settings AGAIN but this time with 13.3Beta_3 drivers and BAMM 700-720kh

WTF!!!

I am using the latest cgminer (3.1.?) and I installed AMD SDK 2.8 separately.  And I have 12 gb of RAM, corsair vengeance.  It matters for scrypt...

Which reminds me, did you try mining a SHA coin, like BTC or TRC?  Were you able to get over 700 mh?  If so then it's clear mem clock speed is the issue.

And use GPU_Z to check if you GPU / Memory is running at correct speed!

Sorry, I missed the part that you had 2 cards.

OK, what have you NOT ruled out yet ? It can be a really silly thing you know. After years of building my own systems I still forget to make sure every cable is plugged in 100% all the way, for example.

Sometimes the only way to find these things is to literallly take everything apart, wipe clean the HD and start again.

Right on.  Maybe it's the --failover-only arg that did it for you...

Nope, that's pool related stuff.

OK, so now GPU 0 is at 705kh but runs at 92 degrees, while GPU 1 runs at 720kh and only at 78 degree!!

Woohoo!  Awesome!  I wish I could claim to be a genius rather than repeating what I had found somewhere online...but glad we got you sorted out!   :)

Unfortunately those temps are the problem with this model gpu if not using riser/extenders in an open air case or on a rack.  Whoever designed the vent flow should be freaking fired.

I can keep all five of mine under 80 degrees, but they are elevated and well spaced out with a box fan on high.

Ouch...too hot.  Are they in a case?  How are you set up?  

At least heat is an easier problem to solve than hashrate!  I live in Taiwan, so my ambient temp in here is pretty much always 30C.  I have one machine in a Coolermaster case that has a couple big 200mm fans in it so it is not so bad...but my other box is just some cheap ass case so I ripped it apart and run with no sides/hdd rack/fan grills etc.  Sometimes I have to point a fan at the second box just to keep it around 80.

Here is something strange, I reset GPU back to stock settings 1000/1375 and tried these settings with no overclock

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

GPU 0 - 520kh
GPU 1 - 720KH

WTF??  any ideas

Hmm i might try your fix with the 13.3Beta_3 drivers. I had given up trying to get my HIS ATI HD 7970 IceQ X² above 600kh/s. It seems to want to run at 550-580kh/s no matter what I try. Already attempted to flash numerous bios files with either no improvement or brick(and thank god the dual bios saved my ass a few times!).

you reset the settings on only one gpu, maybe?

Mate it looks like you have the EXACT same issues as me, amazing that 13.3beta worked

Just one advise,

do this:
run amd_cleanup_util_1.2.1.0 utlity to remove all your drivers, reboot and then install new drivers

hahahaha, your right, forgot I had to do the 2nd card on the drop down box... :-)

no worries, ill give it a shot now and post my result. Fingers crossed.

Yep.  This was my breakthrough as well when I was messing with my other rigs a few weeks ago.  Drivesweeper and Atiman uninstaller, plus going into appdata and win32 and win SYSWOW64 folder and deleting all amd and ati folders/files.

at a certain point in all this I remember my brain just going...blehhhh.  And I went to bed.  lol

It was doing my head in, thanks for your help and everyone else. Hopefully this thread will help many others as well.

damn, still no good for me.  >:(

did you try core clock at 1085?

Ya anybody else having trouble you really need to play with your engine setting to find the magic number.  Set your memory to 1500 and your engine to 1044....or if you want start engine at 1050.  Then move it up or down one number at a time and try to find your sweet spot.  ONE NUMBER can make a huge difference...for my card the engine speed at 1043 = 580kh...at 1044 = 720kh....then at 1046 = back down to 580kh.

Your fans are too slow make sure they are running over 3,000 RPM which is about 60%, many people like to lock them at 80% but I find that a bit noisy.  --auto-fan should work on gigabyte cards, cgminer sets the temp to 75C if you don't specify it.

I just want to reiterate what whitedragon said. Plus or minue one to core or mem clock can change my 7970 hash rate from 730+ kh to like 550 kh.  And it's a cumbersome process, but it's also the best way to find your rig's sweet spot.
