Title: Mining not working, help needed
Post by: Wes1180 on April 11, 2013, 01:24:32 PM
I have tried a few different miners and a couple different pools but it is not working.

I have a Radeon HD 6950 card (with the extra shaders unlocked using this  (http://www.techpowerup.com/articles/overclocking/vidcard/159)method, with +20% power on)
When I start the miner it shows me my MHash/s but it is getting hardware errors and no shares are being accepted and none of them are being rejected, it is just hardware errors.

I used to mine and it was working fine (though this was a couple years ago now, but I was using the same GPU)

I have tried using GUIMiner, PheonixMiner and DiabloMiner.

I've gotten a few different errors,
"No JSON object could be decoded"
"Verification failed, check hardware! (0:0:Cayman, 38570c89)"
"IO errors - 1, tolerance 2"

I've had a look around but nothing really seemed to help.
