Is it to be expected that the hashrate when mining x16rt is varying quite a lot?
In my case it varies between 8 and 16 MH/s (for each GPU) over a few minutes, with all GPUs on a rig showing the same ups and downs synchronously.
Is this a property of this new algo or rather a bug in this very early release?

EDIT: When the hashrate goes down, so does the temperature and fan speed on the cards. So they obviously don't work as much as they should/could.
