Hey guys,
I wanted to get some input from the more seasoned veterans than myself but I have a mining rig that consists of:
2 x 5870 (~430kh/s ea fine tuned)
1 x 5850 (around 372kh/s fine tuned)
and I just got in a 7850
Now everything was running great w/ cgminer 2.11.3 and drivers 13.2 w/ SDK 2.5 manually installed.
The issue is that I received the 7xxx series card and I reformatted the hard drive to install the current drivers and SDK for it.
Now with just the 7850 in place, I am able to get good performance out of it (around 380kh/s with overclocking) but when i try to have all the cards running at the same time the driver is constantly crashing after some time causing cgminer to crash etc. I've tried lowering the overclocks and intensity without success.
The same rig has been 48++hr stable with just the 5xxx cards in place and running I 19.
Are there some tips to mixing generations like this?
