Title: "Verification failed, check hardware!" Post by: kwoody on July 16, 2013, 03:38:29 PM I recently replaced a 6950 card with a 7950 card. The 11.1 drivers I was using on the 6950 were not compatible with the 7950, so I deleted the 11.1 driver, manually deleted the associated files in system32 and syswow64 folders, and installed 13.4(latest) drivers. It appears to start mining but as soon as a share is discovered it throws up an error "verification failed, check hardware", I've been told that there's an opencl issue between the software/hardware that causes the shares to be invalid. I've tried installing multiple different driver sets, like 13.1 as people had good results with that, but that gave me a huge error.
any advice...? Title: Re: "Verification failed, check hardware!" Post by: Zanatos666 on July 17, 2013, 08:01:26 PM Use driver sweeper to make sure you didnt miss anything when uninstalling 11.1 and try again.
