nice ! but . . . 1 gpu goes down, whole rig goes down = lotsa downtime, the initial startup & DAG generation must be loooong. good for enthusiast but imo, it's NOT good or recommended for a newbie. try dual mining & what see it spits out. i won't even goto PSU topic, the amount of mess of cables (heh, except my rigs but still need LOTS of work) & i think 1 of the worse would be to figure out which gpu or hardware is the 1 causing all the issue or the entire rig to fail.
sorry for the -ve points but that's what i think & i hope you take it as constructive -ve points.
nevertheless, HURRY up & share the secret sauce & an awesome job done !
Well the point of this project is to have a cheaper/easier entry into muti-gpu mining that never existed before. This will REDUCE downtime/cost and increase ease of setup, since no risers = no USB cords or riser power cords. Sucks I have to keep rebooting this dev system otherwise I could prob show off a 100+ hour continuous mining with no GPU fails with these boards. I don't even need to mention the benefits for a larger farm.
Of course if a GPU does go down its just a matter of rebooting (about 2-3 min from reboot to full hashing with 16 GPUs, on eth, faster with Zcash or other algos)
no risers & cords (but i'm sure still some are needed to power the board right) will be great but still need to purchase a magical board to fit all 16 gpus in right ? as you mentioned it's cheaper compared to risers, this is really interesting then ! i hope its not too big (enough spacing for cooling) or too small (not enough space for cooling) but i'm sure you have done your homework & tests.
just a quick question that just came thru my head, on a regular setup, if a riser fails we can just replace with a riser & that should solve the problem, what if 1 of the slots out of 16 on the board fails, will it affect others ?
let's see how it all turns out when you decide to release it to the public in terms of practicability, costs, shipping and so on.
i hope it all goes well & if it fits in well for me, i will definitely be ordering a piece to play with or probably try to work with you to be 1 of your reseller/dealer/distributor/partner at this part of the world if you wish too.
i hope there's enough copper (i think minimum would be 2oz & up) on the pcb, 16 of rx's does really suck up quite a bit of juice.
show us some pix of it, a little preview.
much thx for the great work & share especially with this 1 of a kind setup. good work do keep up the great job !
