I have follow this steps and cannot find a way to overclock the GPU. I have flash the GPU bios and I know they work because I tried it on a friend rig and they hash 30M/Hs. How ever when I connected to my rig is only giving me 27 M/Hs and I cannot find a way overclock and under volt. If I have my rig on for more then 30 min it shut down b/c I believe it consume more power then the PSU is capable on providing. Another issue is that when it’s mining a temp status usually show up every once in a while but right now when I start Claymore’s it does not show the temperature. I cannot find a way to determine at what temperature the card are running at. I tried installing trixx that it still does not show me the temperature of the card and cannot overclock which this program.
Hardware the I current have
EVGA Supernova 1300 G2
h81 pro btc r2.0
Sapphire Radeon NITRO+ RX 580 8GB GDDR5
SanDisk SSD PLUS 120GB Solid State
Kingston HyperX FURY 4GB
Intel Celeron G1840 Processor - BX80646G1840
When I connected everything I ran into a problem which was that I could not find a way to boot the OS using the GPU. The way that I solve this issue was by going into the bios and enable the on-board card as primary card. Then I was able to install the driver for the GPU’s by using the embedded graphics card on the board. I have tried enabling external graphics cards as primary but I still get stuck in a black screen if I do that. I’m that sure if that causing this problem.
Can someone please help.
