so what your saying your going to be offering the motherboard for around 70 to 80 dollars? if not its hardly worth it. your still vetting out hardware so to say it will be cheaper in total supporting component costs per gpu is a bit premature. tbh I doubt this setup will be cheaper than compared to a typical 6 to 7 gpu setup not to mention your playin to a niche market and not everyone in that market will see that as viable, I see more points of failure being added etc, thats what I look at. but all in all I guess we all will find out

my question is what happens when you cant deliver on this promise your making that it will be cheaper and it turns out its not, you going to take a hit? doubt it lolz

That's not what he was saying, though...

Using the typical 6-GPU setup, the motherboard ($80), CPU ($40), RAM ($30), OS drive ($20), and risers ($50) add up to $220 (may be more or less depending on sales and availability, but this is about as low as you're going to go most of the time while using a free OS). Divide that by 6, and you have a per-GPU cost of $36.67. I'm not considering power supplies, because you'll need almost the same amount of power for either of these options, though needing only one ATX connection would further reduce costs. I'm also not considering the labor cost of setting up 3 systems with risers vs 1 system without risers.

For the 16-GPU board to be viable, the cost of the board, CPU, RAM, and OS drive combined must be less per GPU than $36.67. That means about $586, minus CPU, RAM, and OS drive (let's say ~$90 for those items). At around $500, this board would be comparable if you're using 3 consumer PSUs. If you're using one of the 4K + PICO PSU configurations, the board is comparable at $550-$600. If you are using a paid OS, you're saving 2x the cost of that, as well, so potentially $700-$800. Personally, I think the time and troubleshooting savings of not dealing with risers, and their myriad potential points of failure, is probably worth another $200 itself for bigger farmers.

I would be shocked to see a custom 16-GPU solution like this at $500, but even double that would probably have a good market among folks like OP.

I don't see OP even touching that, doubt you would see it for $500 and honestly with the setup having so many gpu's it just brings up a whole different set of failure points, as some have mentioned before. what if one gpu fails it could affect the whole rig and that could end up being costly, gpu's down is money lost. what about trouble shooting to figure out which one has failed, that wont be an easy task.

Setup is built around a 8 GPUs per daughterboard(the actual board I'm building). Two of my boards are connected to the mainboard (~$150). My current estimates are around 150 per board..so 300+100 = $450...I guess my estimate price is a bit too low for you then huh Wink

The current board I'm testing can physically connect a total of 18 GPUs since it has two extra PCIE slots...youll will just need risers for that last two (there is a possibility a future BIOS update I could make it to post with 3 or even 4 of my boards for a total of 32 GPUs, but I'm just working on 16 for now...plus I would need to work closely with miner devs for anything more than 16...I have slowly hinted them improvements which they have already implemented for multi GPU setups in the past year).

Also the board has status LEDs per GPU lane...if a GPU goes down you'll know right away which one it is, and yes if one GPU crashes the board will still work. This is no different than any other mutigpu setup, other than it having just more GPU lanes. Your doing something wrong if one GPU crash brings down your whole system.

Keep in mind that this price is mostly dependent on the quantities I can order for parts on the first batch. Obviously more boards = less price per board. I am also pretty much charging the cost of components + a small profit margin for me. The design + dev + testing + prototyping etc is all done by me so thats why I can price it so low.

Take my money now!

Any idea when you will be ready for pre orders?
