Can someoneplease explain why this keeps happening to me and how to fix it ....

When I mine after while some of my miners report they are going speeds in GH/s which is obviously impossible ... I don't know if this as affecting my mining bit I would like it to stop ... also this was the first time I got HW errors ....

See image to see what i mean.. the top 2 are reporting speeds in GH/s.

Thanks in advance for help!

Is this seriously not happening to anyone else ? It keeps happening to me more often.. Basically the GPU is useless once this happens and does not submit any shares.. I keep having to reboot every 45 minutes this is really annoying. Any help would be appreciated.

cheers,

For me, occasionally if a GPU crashes it will start reporting incorrectly GH/s. I'd suggest turning down your GPU clocks, or increasing the GPU voltage or increasing GPU cooling or maybe even two or all of them things.
