Hi. My problem is exactly whats described in the thread below
CGminer - GPU0: invalid nonce - HW error (
https://bitcointalk.org/index.php?topic=179718.0)
I have tried all of the suggestions in that thread and none work for me.
The only mining software I've been able to get my card working with is Reaper, but i have to use the proxy so it uses stratum.
Now that's fine until i find a better solution as sometimes the proxy takes 7-8 mins to send a reply back!
Are there any other alternative software out there that will allow stratum? and work with a ati radeon hd 5670
(before you laugh at the card...i've only been mining a week and just sorting out the technical issues before i spend hard earned cash on better hardware)
P.s
I know guiminer/cgminer work as my onchip graphics work properly
