4GPU to 1Pcie x1

[Benop]

Morning Guys, i wanted to upgrade my rendering rig ( i use octane with 4 GTX 1060 6gb ) since my Motherboard have only 4 PCIE slots and i already have 4 GTX 1060 6GB installed, i was wondering if i can buy this  to add more card ( i have 6 more in my stock ).

4gpus on  1 pcie x1 doesnt sound like a good idea at all. 

These risers are made for mining, because the communication between the cards and the mobo is very minimal. Cards are given starting data sets and then they can just do the calculations without communication.

 

IF your rendering program acts the same way then you can use it, otherways you will get pretty bad performance.

That's a severe cut in bandwidth, and from what I know rendering needs bandwidth, unlike mining. Not a good idea imo.

waaaaittt whaaat ? mining rig uses usb 3.0 connector to transfer PCI, but you can't connect gpu to usb 3.0 extension card and expect it to work lul XDD

I don't know is that usb add on or pcie add on.

All I know is look like this

or this

 

I'm not sure how it will works for rendering since both of these are for mining purpose, while I'm sure it will works anyway but the issue is no one knows how effective that bandwith for your rendering.

 

Mining doesn't use lot's of bandwith since it's only calculating the algorithm.
