Hello,
I just bought Octominer X12 Ultra with rx 470 8gb 12gpus already installed (samsung memories)
Pluged in, but the hashrate of each gpu is 8-9mhs on ravencoin… and it doesnt matter if I apply the overclocks like: core 1100, memory 2000 dpm, vdd and others, the hashrate doesnt change…
Ive seen videos only with rx470 4Gb versions, doing 13-14mhs with ease… what could be the problem?
How can I achieve better hashing? 12gpus only produce 105-110mhs…
what settings are you running? have you tried other miners?
Settings are core clock 1150 memory 2000. But as i said, with oc or no oc at all, hashrate is the same.
I havent tried other miner, as all my rigs on rx cards (580 8gb)hash with teamredminer
have you verified the settings are applying with amd-info? running any memory tweaks?
Yeah the settings is applying, i have undervolted the card, hashrate drops to 5, but they all cant go above 9,5mhs…
While my rx 580 everyone is going 14+ mhs
Hi,
Check your power supply settings. Make sure each GPU is receiving adequate power. Adjust the power limit in your mining software if necessary.
Thanks
