I just wanted to report that I've solved my problem with one of my Vegas being quite spastic, like less than half hashrate of its sibling. My Windows key was deactivated for a while now, and I finally contacted the supports and they helped me reactivating my Windows copy. I got an update, and after restarting both cards are running at the same speed:

you need to cool those vegas, set the fan to 3000rpm.
That is why the hashrate drops, hbm gets too hot
Both are pretty much the same temps wise, maybe the upper one has a degree more.. Much better now since I switched to the Threadripper platform and there's more space between them, on the mainstream Ryzen mobo they were too close.
