good guide

Shits sure they dont have time for shit ,because they are already shit  - my speed outperformanced your stolen settings that got from me .
Dont hope to treat or trick me to show anything to public to prove "loser" or "shithead" because I dont need/want your "appreciate"  and sure I'll not let someone like shit make use of me once more .

hope2907 Pm Yahoo haidzam I will give you a try for 78x

I also have a Sapphire Dual-X 7970, but I don't get anywhere near the settings you posted (1070MHz/1060mV , memory 1750Mhz/1640mV).

Do you have the ASIN (or something like) of your cards at hand? There's a myriad of different Sapphire 7970s out there (Vapor-X, Dual-X, OC, ... plus various combinations and different names) - which one is yours?

g 2 that mean GPU thread 2 , correct ?

which card are you using now? my giga 7970 oc v1 have to 1080/1880 to get 740+

great rig

did you say that you showed me these settings ? well i do not understand what is your problem neither understand what are you trying to achieve with this , but i am sorry that you think that about me , and actually i do not think that i am any talent and i do not beg any one to give me anything.

edit: and yes i really would like to see your 8xx+kh/s we would appreciate you sharing it with us, you will help LTC that way, only this would make you better than me Share an prove that you are a"talent" and i am the "loser" and do not just berg about it
  

When you have time ,read this in your Skype  ;DI sent it after see this post ^^ .

i will when i have time for it.

nice temps and hashrate! will you take a picture of the rig for me? how is it running so cool?

I saw that allot of guys struggling to get their 7970s to work over 700 Kh/s, and as it took me few weeks as well and allot of energy and allot of nerves and risk of hardware fail to get the right configs i thought it would be nice to post it here to save you allot of time and confusion and nerves, at the same time it is a big push for LTC to increase the market capacity making sure that you are getting the maximum out of your cards.

just to justify something , this results were reached with the following setup, i am not sure neither didn't try different models/OS/vendors. this is what i do have:

- Windows 7 Ultimate x64 SP1
- AMD FX6100 Six-core
- Gigabyte GA990FXA-UD5 (5 PCI-E 16x although they wont work at full x16 if more than 3 cards)
- 2x8 GB Crossair 1600MHz DDR3
- 64GB OCZ SSD
- Enermax Platimax 1500 W (otherwise i recommend a PSU with only one 12V rail )
- 4x ATI sapphire DUAL-X HD7970
 

- if you want to put more than 4 cards in one system (did try up to 6) than you must install ATI catalyst 12.6 it is the only driver which can support more than 4 similar cards. otherwise it had ATI catalyst 13.3 beta.
-if you are starting from scratch with new installation you are good to go, if not downlaod driver fusion and delete all previous drivers, install catalyst 13.3 beta than you are good to go.
- get the latest MSIafterburner, install it than go to the installation folder and open the CFG file with your notepad change the value as shown in picture bellow





-after that go to the control panel chose power options , use performance as your default profile and make sure that it looks like this








- set your cards with MSIafterburner with this settings core 1070MHz/1060mV , memory 1750Mhz/1640mV and make sure that your Temps are not higher that 72 C° otherwise you will have to think about better cooling.
-get Cgminer 2.11.2 or 2.11.3 it didn't matter for me , make sure to delete all bin files if you already have cgminer and Start it with the following settings --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

you will get this results if everything works for you , maybe you will get even better results if you are lucky
