GPU speed problem

[kryptominiu]

Hello,
I've just build my first GPU miner. I connected to NICEHASH and here is problem - speed is drooping to 0 and then go back ( as photos ).

Anyone have same problem - or maybe I have to check my internet connection ?

What GPU are you using ?
What overclock settings?

have you checked the logs?

How long have you set the switch-over

I don't think nicehash has good enough charts to see what you're really mining at accurately. What you are seeing is not "speed" (which is also more commonly referred to as "hash rate"), its profitability. It does have a tendency to fluctuate especially if the coin you are mining is more volatile. If i were you, i would look at your miner directly and see if it's hash rate is indeed fluctuating up and down.
