The only thing I've needed to change for Vertcoin is thread concurrency. These seem to be the optimal ones for the cards I've tried so far:
R9 290: 24550
7950: 19712
5850: 5120
Thanks for the 5850 TC. 5120 seems to be the only one that works.
just started mining this and I was wondering if half of the speed you get running scrypt is normal? Also it really slows down the pc compared to scrypt.
my 5850 normally does about 320 kh/s and with this coin it does 160 kh/s, is this normal?
I use this:
--scrypt -o stratum+tcp:// --intensity 16 --gpu-engine 800 --gpu-memclock 1125 --worksize 256 --thread-concurrency 5120 --no-submit-stale --failover-only --queue=0 --scan-time=0 --expiry=1 -g 1
