Hello, I'm crossposting here from the sph sgminer thread, I know I shouldn't but nobody answers me there:
I have a sapphire r9 290 which doesn't want to move the memory clock from 150 when mining darkcoins, leading to 1/10 of the available hashrate. All other cards are fine, and the card mines fine with other miners (engine clock can be changed instead).
Please help!
try editing the sgminer default .conf file to force values....
also, make sure you compiled with the right AMD sdk + AMD APP
I run it like this, but I've tried any other possible setting:
-I 19 -w 128 --gpu-engine 1100 --gpu-memclock 1250 --gpu-powertune 20
I'm on ubuntu with fglrx 2:13.200~beta-0ubuntu1~xedgers~saucy2.
Compiled many flavors of cgminer and sgminer without issues in the past.
