Title: LTC mining question Post by: altoz on April 24, 2013, 03:54:57 PM I have 3 6950's mining litecoin using cgminer. 2 of them get around 400 KH/s. The third one gets only 80 KH/s. How do I get the third one to get 400?

How do I get the third one to get 400? If all three are in the same machine, make sure your PSU is sufficient for all three cards.

Title: Re: LTC mining question Post by: flyingmonkeycrap on April 24, 2013, 07:50:18 PM did you make sure of the simple things like clock speeds are all the same for each card and all have intensity 18? What is your thread concurrency?
Title: Re: LTC mining question Post by: altoz on April 24, 2013, 07:51:38 PM Intensities are all at 15.
Thread concurrencies are at 8192. I'm running a monitor off of one of them through the DVI port. Title: Re: LTC mining question Post by: altoz on April 25, 2013, 04:54:58 PM SOLVED
Steps: 1. I uninstalled the AMD drivers/programs/anything related. 2. I uninstalled the microsoft things (some redistributable and .Net stuff) 3. I installed the driver 4. I installed the SDK Now all three are getting good speeds. |
