I have ATI HD 7970, currently getting 606 kh/s.

My clocks are GPU 1125 and memory 1575. Using cgminer 2.11.4. (Maximum overclock, this card comes with 925 and 1375 stock clocks and it is stable)

How do you guys get close to 700, I have tried playing with my clocks, tried to get 0.57 ratio between GPU and memory, no luck. Drivers are 13.1.

My current setting are --worksize 256 -g1 -I 13 --lookup-gap 2 --shaders 2048 --thread-concurrency 8192

Any ideas?

Thx

try this -g 2 -I 13 --shaders 2048 -w256

use cgminer 2.11.4 do not set thread-concurrency let cgminer detect the best value for your cards, maybe try the last beta drivers 13.3, i get more than 720 kh/s with core1040/memory1750 with vcore unervolted and vmemory overvolted , i did order Arctic extreme cooler tried it on 1 card and it is amazing I am getting around 67 c°with these setting comparing to the other cards that are running @ 86 c° I did order more coolers for the other cards, it is worth every cent I did give.

Skip the worksize and the -g1 setting. Get your memclock higher-> closer to 0.57-0.60. Then up your intensity to minimally 18 then you should see higher hashes.

But you probably have different card. When I go with g2, I get much lower hash.

I have nearly identical settings to yours, but i have -g2 instead.

I was poolmining with intensity 20, cgminer showed my hash rate being about 700kh/s, but the pool registred <10 kh/s.

I lowered intensity to 13,and now the pool accepts my shares much more frequently.

cgminer shows the 580kh/s rate atm.

Is that a common problem? i should be able to poolmine at higher intensity, right?

EDIT:

Think i finally managed to sort out my poolmining !

If you are ever getting hardware errors, you need to fix your settings.

Do not use Reaper. Ever.

My question is: will cgminer even display HW errors in solo mode? Or does everything just stay at 0?

Anyone here have newest sapphire 7970 vapor-x with 8+8 pin's? Any mining results? Power consumption?

Thanks for this guide. I am having a small problem with 2x 7950s on win 7.
Whenever I pool (coinotron, ozcoin) mine at intensities greater than 12, I get 90% HW errors and can only get around 200khash / card
However, when I solo mine I jack the settings all the way up to -I 20 for ~600khash / card with 0 HW errors.
So my main question is, when solo mining, does cgminer detect and display your HW errors? Or is HW error detection built into more sophisticated pool software?
Would really suck to be hashing garbage forever and not know it.

I've come to a conclusion that cgminer 2.11.3 is a lot faster than 2.11.4 on my 7970 cards. I can get up to 15-25 kHash/s more on the older version. I hope others will try and report here if that also applies to you.

Solo mining atm, 685khash/s, overclocked the card to 1100/1500,70° at full load.

Should i push the card even more? 70° is pretty decent at fulll load, isnt it?
the card is a 7970.

Just reinstalled Windows 8 from scratch. I have 2 7950's. All I had to do to get cgminer running was install the latest beta drivers and everything started working.

Dont be affraid to play with 11.2 and the thread concurrency of 8192 with your 7970s. In my rigs I have to overclock even further and use even more electricity to get the same hash rate on 11.3 as I do on 11.2. Needless to say I have stayed with 11.2!!!

Used SoloEasy tool to get the cgminer running, intensity at 20, averaging about 630 khash atm.

Stuck at around 300 khash/s on my 7970 atm Sad

Sad

running factory clock settings, using reaper.

Code:

worksize 256
aggression 13
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 8192

have tried alot of diffrent clock settings/thread conc, the best i managed around 500khash/s.

Any suggestions?

woah there cowboy...

use these settings..

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 28
lookup_gap 2
gpu_thread_concurrency 21712

note: you'll need about 2gb of system ram PER CARD using reaper

i'd personally recommend cgminer.

620khashes now, yay:D

I couldnt get the cgminer to work before for some reason, but will give it another try!
thanks!

1) Why are you using one year old code, that was broken back then, to mine with? Use cgminer.

2) Of course you're getting 300kh/s at aggression 13. Increase it to 18, or 20.

had no clue it was broken:O
