Title: Overclocking Cards on 1x Riser Post by: bluegreenpurple on January 23, 2014, 06:35:39 AM Hello, I have been trying to find info for 4 hours and couldn't seem to find the answer to a question. I am currently running ubuntu with 4 R9 270x's with 2 directly connected to the MoBo and 2 that are on 1x to 16x (usb cable) powered risers. I use cgminer. all cards show up and are mining, but the cards on the 1x risers are 70KHashes slower. cgminer doesn't show some of the info for the GPUs on the risers. Is there a way to overclock the GPUs on 1x risers? cgminer isn't showing the gpu temp, fan rpm, clock speed, mem speed or any other value in the change settings screen for the GPUs on risers. I have tried to input values but it just fails. I have also tried aticonfig overdrive and it doesn't show info for the GPUs on risers either Any help would be appreciated Thanks!
