I have a problem with my r9 290s, the memory clock stays at 150mhz whatever I do. I can't change it with cgminer or conf file or even afterburner it always stays at 150...
do you have it on all the cards or just those that isnt "the main card"
sounds like thr cards are idled. i had this issue on some rigs with windows.
needed to make dvi dummies to fool the gpu out of idle:)
max.nut2pools.comOn all my cards, the problem is only with cgminer for keccak, it works perfectly with sgminer, cgminer for vertcoin, etc.
My hashrate are about:
415 MH/s for r9 290 with engine clock 1000mhz, memory clock 150mhz
400 MH/s for 7970 with engine clock 1200mhz, memory clock 1050mhz
