What is your GPU voltage set at?

Took a lot of tweaking to get that speed outta it and stable..

Same card will do 750 kh/s on normal scrypt with core voltage at 1.019.

Might buy a 7990 to play with but it wont be a Gigabyte one!

Good config for R9 280x and maybe 7970

If theres anyone out there stuck at 475 kh/s using this card, try this:

--scrypt-jane --sj-nfmin 2 --sj-nfmax 40 --sj-time 1388361600 -I 14 --gpu-engine 1225 --gpu-memclock  1500 --thread-concurrency 8192 --temp-target 85  --expiry 1 --queue 0 --no-submit-stale --vectors 1 --gpu-powertune 20

Getting 535 kh/s stable on my Gigabyte Windforce 280x. Core voltage is set to default (1.163v)

Still getting a few hardware errors (15 in 10 hours) but its working well, gpu temp at 69-73 degrees.
