help me please: 270x can't mine
« on: March 21, 2014, 07:23:22 PM »
hi everybody, I have one problem: I have this rig: MB gigabyte matx 88x chipset with 2x 3.0 gen PCI express, the hardware is APU kaveri 7850 black edition + sapphire radeon 290x + sapphire radeon 270x... the apu's gpu (r7 260) is mining at 50 khash...(I think it should mine around 100)...the 290x is mining @650 khash (it should mine around 800)....and the 270x can't go over 40 khash... I tried every batch configuration even setting only the --shaders 1280 without other customs but nothing... it doesn't mine over 40.... the catalyst is 13.12 and in it I can see that the apus gpu and the 270x are disabled (I think this can be a problem only for gaming) please...i don't know how to solve this...
thank you everybody

At first, I would forget about apu's gpu mining and would concentrate my efforts to mining using your video cards. I'm not an expert, but you have to be sure that all drivers installed properly and check with GPU-Z utility if all of them are enable and running. I do not remember, but I guess you need to use 75 Ohm resistors connected to your videocards outputs to make Windows think that you have all video cards connected to monitors. If I am not mistaken you need to do this if you running XP, but im not sure, google it.
Do not forget to remove bin files after any mining config changes. 7850 should have about 300KH/S, 290X should have about 800 I think, cause my 280 gives 720KH/S.
What OS you are using?
