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

[whitedragon]

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 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.

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.

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..

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

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

WTF!!!

[mercSuey]

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.

[sikman]

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

[yager]

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... :-)

[yager]

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.
