Hello, newcomer here. Although I have made quite some researches on many topics, I still got to learn.
My plan is to build a 8 x 1080Ti rig.
About motherboards, I am hesitating between :
- ASUS PRIME H270-PLUS (6x PCI-E + 2x M.2 slots)
- Asus Z270-A mobo (7x PCI-E + 1x M.2)
- BTC250-BTC+ PRO (8x PCI-E)
First I was going for the H270-PLUS in order to save bucks.
Next thing I am told is that M.2 to PCI-E adapters can be tricky : there needs to find a sweet spot when pushed in, otherwise the “contact” can be very sensitive. Can a M.2 adapter displace itself on it’s own and lead to an off card some mornings ? I would not want to lose connectivity each time the rig is moved or parts randomly touched by mistake for instance.
I can also read some reports online that the hashrate may be sometimes lower from a M.2, than a PCI-E, unsure why exactly.
Last, I am warned about “lanes” which I might lack enough since I am using 1080Ti. Lanes is a concept I have no knowledge about… could you please tell if M.2 adapters are to be avoided at all cost to run a 1080 Ti ? Therefore, is the Biostar the only mobo recommended for my 8x 1080Ti setup ? All PCI-E as mandatory ?
As far as could be, my goal is to build a “plug and play” rig that won’t make me lose time on random issues, so I can grow some will to run more than one at a later stage. Hence, me going into details
