Title: Just added a 2nd Gpu to mine with and not working properly! Post by: siikfo on December 12, 2013, 10:53:14 PM ok just a little backstory.. i was mining with a 6870 and i just got a 7850 installed about 5 minutes ago so now im running two gpu's
with the 6870 i was getting about 300 kh/s but now running both on intensity 15 and up (wont change) they both get about 16-20 kh/s no matter what i set the intensity to.. any ideas how to fix this? i am using cgminer 3.7.2 Title: Re: Just added a 2nd Gpu to mine with and not working properly! Post by: Kluge on December 12, 2013, 10:58:29 PM Sounds like behavior from running them in Crossfire mode. If that's the case, you should either take them out of CFX mode or significantly lower the intensity (there is no way around the hashrate loss in CFX, AFAIK).
If it isn't the case, I've got no fuckin' clue. :) Title: Re: Just added a 2nd Gpu to mine with and not working properly! Post by: siikfo on December 12, 2013, 11:00:32 PM im not running them in crossfire mode. and when i change the intensity it does nothing :/

Post by: Kluge on December 12, 2013, 11:13:08 PM Maybe the device codes for the different OpenCL devices changed and it's mining on the CPU? Maybe try them on GUIminer-Scrypt using default config for your cards to make sure it isn't a config issue?
