I'm starting to suspect I have a failed PCIE slot but I ran out of time to continue messing with it last night.
..figured I would post here to see if anyone else has had this issue.
This rig has been fine for near a year running 4x RX480s without issue.
I just swapped all those 480s for 1070s yesterday and now it will not detect any GPU placed in PCIE16_3 on the board.
I swapped the cards around to make sure it's not the 1070 and that's where I ran out of time. 1070's are fine.
This board is supposed to support 4x Nvidia or AMD cards but my question is has anyone else running Nvidia cards out there ran into this or a similar issue with an Asus board?
As I ran out of time I didn't yet try throwing an RX480 in it to see if it worked or not.
Thanks.
I have a similar situation with a MSI Z170 M5 coming with 3 full PCIE and 4 short slots.
1. No problem for on board 2X 1080 Ti + 1X 1070, or 1 x1080 Ti + 2 X 1070. Failed to start with 3 X 1080 Ti
2. With risers, 4 X 1080 Ti + 2 X 1070 work with specific PCIE slot combo. Failed to start once I put specific cards in two specific short slots. Also occasionally (not that frequent) I lost one card during mining resulting crashing, considering upgrading my PSU for this.
I asked around and some senior members here suggests that might be due to insufficient PCIE power-supply in situation 1. Even you have a WS ASUS board, which might not be designed to handle four thirsty GPUs on board. You see here my Z170 only gets 2 X 1080 Ti + 1 X 1070.
May be try powered riser 1st.
Thanks for the suggestions but these are plugged directly into the board, no risers and I'm using a 1600W PSU that worked fine with the 4x RX480s that pull more power than these 1070s do.
Even though I had the compatibility mode turned on I fear the Ref RX480's with 6 pin connectors I had toasted the slot.
I bought another board today but will try a few more things when I get home. Going to try just 1 1070 in the dead slot and see if it works, then try 1 RX480 -- if it doesn't work then, I know its dead.
