If someone has a clue as to why 4 perfectly running vegas started to hashrate drop in a frozen windows installation, please share!

What miner are you using? Any recent temperature increases on the cards? Are temps in check?
Assume it was a significant hash drop?

As I said above, one of the possible changing variables (everything else is fixed by deepfreeze) was the cards temperature. Raising the card fan speed didn't solve the issue. They all sit at about ~55ºc (hbm 65ºc).

The drop is about 300 h/s on each of the 4 cards. It appears to happen simultaneously on all cards.
