Need help for gpu config.

[Muhammad Osama]

Hello everyone

Sorry for my bad english.

 

I am building a separate pc  for mining.. i am not investing that much right now.. my first question is i am getting intel dq45cb motherboard for very cheap and since in gpu mining we really don't need a good cpu that should be enough. it's an quad core cpu that could easily run windows and nicehash. now the question is dq45cb has one 16x pcie slot and two 1x slots. now i know we can connect risers but still i wanted to confirm can i connect two more gpus to my 1x slots? in short can i connect a total of 3 gpus to this board? and also will my gpu performance drop significantly by connecting risers?

Nvidia cards require 8x minimum to my knowledge. I don't know about AMD ones.

for SLI yes

for connectivity, no

theoretically yes, im using some board's 1x slots for GPU mining

but i've owned a board that absolutely refuse to boot if i plug in more than 2 GPU at a time in any slot

sending out error in POST related to multi GPU

Just the latest generation then maybe? I seem to recall Nvidia preventing their cards from showing up on anything less than 8x to prevent the riser or less-than-8x (mining) business, but perhaps I recall wrongly.

not that i know of, i've been using risers on my gpu from 900 series, no issues whatsoever

no perf differences either
