Title: ATI 4870 Crashes Can't Mine Anything With CGMiner Post by: mainguy1984 on March 12, 2014, 02:47:14 AM So I upgraded from a POS card with like the smallest fan on it lol was only getting 32kh/s with DogeCoin hey still better than nothing
I got this 4870 Sapphire Radeon ATI video card and no matter what program I run (CGMiner, GUIMiner, etc) It crashes before mining. While the POS video card still mines 32kh/s if I put it back in. I tried downloading a new version of cgminer and that didn't work. According to https://litecoin.info/Mining_Hardware_Comparison the 4870's should get around 120 - 140kh/s which isn't bad for being so cheap, so it'd be great if I can get this to mine! I hope someone here at can help me out this has been giving me a headache for a couple long nights. Thanks guys! If it helps I'm using Catalyst 13.1 with CGMiner 3.7.2 it doesn't give off any specific error it just crashes "CGMiner has stopped working" 1 second after I press enter this is my config cgminer --scrypt -o stratum+tcp://stratum-us.doge.hashfaster.com:3339 -u myusername.workername -p mypassword I'm not using any high intensity settings or anything. I've TRIED uninstalling drivers and re-installing 13.1 13.9 and 14.2 beta all CRASH on CGMiner. Games run fine. I read something about a BIOS Update to these Sapphire cards that might do the trick but all I find are dead links. I heard that there may be a new bios update for the Sapphire 4870 but all I keep finding is dead links and no good tutorials on how to flash it within windows. |
