So, I just built this rig yesterday and after some tweaking, I've gotten it to work stable at the following: setx GPU_MAX_ALLOC_PERCENT 100 --scrypt -I 13 --auto-fan --temp-target 75 --gpu-engine 1105 --gpu-memclock 1775 --shaders 2048 --thread-concurrency 22400 But that is only yielding around 560KHs per card and I know they can produce more. I have 4 XFX Double D Black Edition 7970s. Win 7 x64 Enterprise. Drivers are 13.3. I have tried in reaper with similar settings but it mines at a 560KHs average too. The good thing is there are 0 HW errors and the WU ratio is .93. Any ideas on how I could get these babies past 600? 650? 700? Increasing the Intensity lowers the hash-rate significantly. Thanks in advance! ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.ximages.net%2Fimages%2F59777524370842787457_thumb.jpg&t=665&c=Lpw53ERHQGb64g) RESOLVED. Check below.

Lol I refuse to think that is the maximum output. There must be a way. What drivers are you using? I am thinking about giving the 12.8 a shot.

Drivers 12.10 yield around 590 per card, relatively stable. Its only been going for like 10 minutes, but, I'll keep messing with it. Will probably give 12.8 a shot tomorrow.
12.10 ->> Mem 1800, Engine 1145, I 13

Care to give a little more info? Ive got the same cards and can only squeeze about 530kh/s out of each. Your settings give me 480kh/s ![Sad](https://bitcointalk.org/Smileys/default/sad.gif)

I have my cards set to this in afterburner: Core Voltage 1100 mV Power Limit: 0% (you can bump this up to 10% but your cards may run a little hot) Core Clock: 1075 MHz Memory Clock: 1650 MHz
cgminer settings:
setx GPU_MAX_ALLOC_PERCENT 100 cgminer --scrypt --auto-fan --temp-target 79 --thread-concurrency 24000 --intensity 20 --worksize 256 -g 1 -v 1

Is that overvolting them? Im not sure of the stock voltage is why I ask.

stock voltage on these should be 1069 mv i think. I was just messing around with setting to see what I could get out of them.

7970s that only run up to intensity 13 tend to like -g 2. Try it and see if it improves your hashrate

Unfortunately two GPU threads doesn't help. In fact, it lowers it significantly. I can increase the intensity though with 2 but that only yields upwards of 530 which doesn't compare to the 590 I can get without it. I just think I need to buy a different brand card. I can still return these. Anybody know which cards will produce 700+?

Might be of some help: https://bitcointalk.org/index.php?topic=161047.0I ran into a similar issue and downgraded my drivers (12.10->12. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) and that helped on Linux significantly. I haven't over-volted the cards though. Getting stable 2250kh/s on 4x7970s with the settings listed on that thread.

I'm getting about 590 per now on 12.10 with the following but this will only be for a few more days. Just bought 4 of the Gigabyte cards that everybody seems to have 700+ with. I'm just gonna RMA these XFXs as soon as those babies come in. setx GPU_MAX_ALLOC_PERCENT 100 cd C:\Users\LTCMiner\Desktop\Mining\Dr_12.10\cgminer-2.11.4-windows cgminer -o stratum+tcp://notroll.in:3333 -u XXXXX -p XXXXX --scrypt -I 13 --auto-fan --temp-overheat 85 --temp-target 75 --thread-concurrency 22400 --gpu-memclock 1725,1775,1775,1775 --gpu-engine 1100,1145,1145,1145
\\The one card running lower crashes at 1775/1145 but runs stable at the set clocks. Still pushes 580.
I've tried 12.8, 13.1, 13.3 and nothing yields anything like the above, at least from my tunings. I tried -g2 with lower TC and pretty much every different config I could find. Essentially, I am just assuming these cards are not good for hashing and that's that.

I think that 700 number is a bit of an embellishment for most people ... I have yet to see a screen cap with it. I'm told by the author of cgminer (in that thread I linked) that over-volting is a bad way to squeeze some extra hashes out of your cards...but I guess it really depends on if it's worth the trouble...

They are not getting those kinds of numbers without really pushing the cards
I have 2 7970 and get at most 650 on each without running it really hard. I had trouble with cgminer and the 7970's and got much better hash with reaper, but I think you just add thread concurrency to cgminer and you can get good hash with it too. The TC is important and make sure you have no hardware errors.
