I tried the new gpu miner in the OP.
Ran fine for about 3 hours then I had the lock up again . I am puzzled at what is causing this.
I have no issues at all running my Nvidia cards but can't get the AMD to stay up and running.
Using Windows 7 64bit driver 13.12. I thought maybe driver issue but someone else posted same issue using driver 14.7 on Windows 7, though not sure if they are on 32 or 64 bit.
i think you should try 14.4 at least or maybe even 14.9
but it does sound more like a heat problem or maybe faulty hardware
Yea sounds tht way to me too, maybe the fan speed is not high enough allowing card to overheat. I've started a new miner before and not noticed the fan was barely running untill it overheated and crashed the comp.
I'm getting 9.3 Mh/s on my 290x bf4 an 3.6 Mh/s on hd7850. Didn't do much tweaking last night as I was late getting my cards launched but Today Im going try to tweak alittle more but overall the miners seem to be stable. One rig is running windows 8.1 x64 w 14.7 drivers and the other windows 7 x64 14.6 drivers
