Historically, there has been a 8 card limit due to non 64bit BIOS support, so that may be an issue. I would contact SuperMicro and confirm you will not run into that issue. Otherwise, should be fine with everything else.

that is a grate idle i will email them before purchase the MB 
THANKS

if there is a 8 card limitation i will go with  GTX 980 Ti for sure

any specific type of cooling you can recommend for the cpus?

also note that with 8 gpus you will have 8x 100% cpu load because of shitty nvidia opencl runtime. make sure you have enough cpu power

are u not afraid of it to get really hot for the cards?

it does not look like the cards will have lots of space between them.

i think thats enough.

why would u use linux instead of windows?
in windows u could also use Hash manager which works only on windows.. and support over 400 algorithim, i think u will have less problem with drivers on a windows machine to..

about the cpu, that should be ok i think, each cpu support up to 40 pci lanes
Quote:Max # of PCI Express Lanes

40


meaning the cards wont use x8 or x16. it will use only x4 (if i am not wrong)
with 2 of ur cpu u will have up to 80.


11x16=176
11x8=88
11x4=44

most of the xeon family support up to 40 pci lanes
please some one correct me if i am wrong.

I actually think Nvidia cards can't run with only 4 lanes, not sure if that's just in SLI or what but I recall seeing something about that. Might be helpful to double check especially if you have other stuff running through PCI.

I checked my system (1cpu xeon, 2 x gtx1080),
I took the card1 x16 slot and second card is x8 slot then check the benhmark same speed ~417kh ~414kh.
