try to remove: -w 256, --lookup-gap 2, --thread-concurrency 32765, -I 13
a bigger psu? 300W per card = 1200W, you are right at the limit.
an r9 290 can make 450 with a bit of overclock, but not in your case, cause of not enough current.
thanks I know I'm at the limit, will upgrade to dual psu soon. nice to know that the settings are not bad anyway.
Tried without -w 256, --lookup-gap 2, --thread-concurrency 32765, -I 13 and it's +- the same.
Hi guys it's me again with the 4x R9 290 rig.
I added a second PSU to power the last GPU standalone and the results have been good. I am now able to overclock to 1100/1425 in a climatized room.
-g 1 -w 256 --lookup-gap 2 --thread-concurrency 32765 -I 20 --temp-overheat 90 --temp-cutoff 95
