Title: Temperature sensor defective or Bad Install ?! HELP!
Post by: void9 on January 30, 2014, 10:09:54 AM
Hi,

just got two new 7950 sapphire to try out... plugged in, worked fine for an hour, temperature never reached more than 70C. But 1 of the cards the hash rate wasn't stable was droping like 100Kh/z then slowliy going back up and droping again..

i uninstalled the ati drivers, rebooted, re-installed and now a very strange thing happens...

if i ran the "sudo aticonfig --adapter=all --odgt" command, i see

Adapter 0 - AMD Radeon HD 7900 Series
            Sensor 0: Temperature - 6499066.00 C

So of course CGminer won't work with bad sensor data like that (to my knowledge)

is this a defective card or am i missing something, btw this is my 7th rig, so i'm pretty use to setting them up....

thanks!
