Title: Instable Rigs with Saphire RX480 8GB Nitro OC Cards Post by: jadefalke on November 17, 2016, 01:01:41 PM Hey Guys,
i have multiple Rigs with the following Configuration: ASROCK Pro BTC Mainboard 6X USB Riser 6X RX 480 Nitro OC 8GB Celeron G1840+4GB Crucial DDR3 RAM Seasonic 1200 Watt Platin PSU The Rig is build pretty strait forward and running with Ethos, it is starting quite ok, but then after a time cards start to stop hashing. Some rig's do better and only one card is failing other have 3-4 Cards failing. I tried also another Mainboard (Asrock Anni H97) but the Problem is still the same. I think it has something to do with Power distribution or the Cabeling. The PSU has 7 Dedicated PCI-e Connector so each card has an own 8 Pin Connector, the Riser are powered via SATA Cable, 2 cards share one cable from the PSU. On one Cable the SSD is also connected. I tried to move cards around on the PCI-E Slots but that does not changed the Problem. Did anyone encountered same Problems and found a Solution? Any Help appreciated.

Did you try removing a gpu to see if it became stable?

Thanks for your input. Title: Re: Instable Rigs with Saphire RX480 8GB Nitro OC Cards Post by: jadefalke on November 17, 2016, 06:09:05 PM It could be power related.
