Hi,
Can i add 2 gtx1070 Ti (for mining) to a Gigabyte GA-AB350-GAMING 3 ( on the 2 others PCI-E 3.0 16x ports, without risers) when i have already 1 gtx 1070 Ti in the first PCI-E 3.0 16x port (for gaming) ?
Or do i need absolutely risers for those 2 cards ?
Thanks in advance
No.
Risers are needed either for pciex16 -> pciex1 transition or if directly installed card blocks another slot.
If you can install 3 cards in 3 slots directly, do so. It's probably even better.
