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.

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.

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

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.

damn, still no good for me. Angry

did you try core clock at 1085?

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!).

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

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.

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

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

you reset the settings on only one gpu, maybe?

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

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

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

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.

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.

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.

Quote from: hope2907 on May 19, 2013, 02:42:32 AM

-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!!!

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!

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

Nope, that's pool related stuff.
