Thanks GPUH and put me down for 14 of them, best guess.  I haven't made it out to my rigs to know how many m2 slots I have...

To all: does anyone want to help me compile a list of the best parts necessary to run the accelerator? I am such a novice, so forgive me if this isn't helpful.  Here's my first iteration, and of course let me say that I haven't ordered yet and am not "counting on" GPUH to come through or any of that.  Just trying to be ready if this ends up being a "thing."  Without further ado:


https://www.newegg.com/Product/ProductList.aspx?N=100007627%20600307108&IsNodeId=1&Submit=ENE .  This is a starting point that's a filter for the mobos with the most pcie x16 slots.  You have to dig in each one to find out the true numbers - it's not entirely clear to me but it looks like even with that filter, some slots are the x16 length but not x16 strength.  For example, this ASUS one looks to be able to provide 4 slots at x16 strength (power? data? not even sure what x16 is, lol) https://www.newegg.com/Product/Product.aspx?Item=N82E16813182968

As far as CPU's, it looks like they need to be strong but nobody has stated how strong.  It also sounds like iterations of software could come out that rely less on the CPU's strength.  Somebody please correct me if I am wrong.

m2: Well obviously you need to have at least 1.  It has been said that 1x m2 slot can work for multiple cards, but it isn't entirely clear whether or not 2 will work better enough to justify buying 2 for 4 cards, 2 for 6 cards, etc.  I could have missed something or obviously something could have went over my head.

@Iamtutut has the x470 which seems a great value.  It's here: https://www.newegg.com/Product/Product.aspx?Item=N82E16813144177&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Motherboards+-+AMD-_-N82E16813144177&gclid=Cj0KCQjwgMnYBRDRARIsANC2dfk4QffGNjnVh_uI4dD9TGFwDHk6Kz4uV5Dxoz2wodzJ5Pi1dkECO8waAt7kEALw_wcB&gclsrc=aw.ds

It indicates it has 3 x16 slots, but one covers up an m2.  That will probably be OK (3 GPU's on 1 m2 connected FPGA accelerator), but I def am not an authority.  That represents my best target on first pass.

Hopefully this helps, spurns some discussion and research. 

Thanks,

Nate
